    OPINION OF THE COURT
    ____________
    HUTCHINSON, Circuit Judge.
    Appellants are three groups of plaintiffs whose
    separate actions were consolidated by the district court because
    they all claimed they were harmed by exposure to toxic wastes
    appellee, the United States Army ("Army"), had deposited in lands
    once a part of the New Cumberland Army Depot ("Depot").      In all
    three cases, plaintiffs sought class certification, but the
    district court denied class certification.1   One group of
    plaintiffs consists of workers for the township ("Township
    Workers") who converted the area the Army used as a landfill into
    a soccer field after the Army had transferred it to the township
    that adjoins the Depot.   The second group consists primarily of
    residents living near the landfill (the "Neighbor Plaintiffs").
    The third group are persons, primarily children, who played
    soccer (the "Soccer Plaintiffs") on the field created on the site
    of the Army's landfill.   This third group includes two children
    of the Elliott family, Todd and Tracey (the "Elliotts").      Tracey
    suffers from leukemia and Todd from enlarged lymph nodes.
    Except for the Elliotts, the primary relief all parties
    seek is medical monitoring.   They appeal the district court's
    final order for the Army on all their claims, which was entered
    following orders granting the Army's motions for summary
    judgment.   Their appeals raise several important issues.
    Ultimately, we will affirm the orders of the district court with
    respect to all appellants except the Elliotts, the only
    plaintiffs who have been able to produce evidence of actual harm
    by medical evidence showing the Elliott children are suffering
    from conditions that require medical attention beyond the medical
    1
    . Basically, the named plaintiffs sought to include all persons
    exposed to any toxic substances the Army had deposited in the
    affected lands.
    services everyone in the general population should have.    Our
    reasons, which differ somewhat from those of the district court,
    follow.2
    I.   Factual History
    A.   The History of Marsh Run Park
    1.   NCAD's Use of the Land as a Landfill
    The New Cumberland Army Depot is located just east of
    the Harrisburg Airport on about 974 acres of land, between the
    Pennsylvania Turnpike to the south and some railroad tracks and
    the Susquehanna River to the north.    From 1917 until the mid-
    2
    . We may summarily dispose of two of the arguments appellants
    raise on appeal. We hold that their argument that the district
    court abused its discretion when it denied class certification
    lacks merit and so will affirm the order denying class
    certification. We also reject appellants' argument that the
    district court erred in denying "Plaintiffs' Motion for Emergency
    Relief," relating to a discovery motion filed in a separate case,
    O'Neal v. United States, No. 1:CV-90-1073 (order filed Nov. 16,
    1993). The district court had consolidated O'Neal with the
    instant case for discovery purposes. It held that counsel for
    the Depot correctly sought to preclude plaintiffs' counsel from
    contacting current or former Depot employees about the case
    without first complying with 
    32 C.F.R. § 516.35
    (d). This
    regulation requires an individual seeking information from
    present or former employees of the Army to make the request in
    writing to appropriate Department of Defense personnel. It is
    known as the Touhy provision after United States ex rel. Touhy v.
    Ragen, 
    340 U.S. 462
     (1951). The United States argues this order
    is not appealable because it was entered in a separate case not
    before the Court in these appeals. Because O'Neal was
    consolidated with Redland for discovery purposes, the United
    States also argues that the motion was untimely because discovery
    had ended and summary judgment had been entered in Redland on all
    issues but one when the court denied "Plaintiffs' Motion for
    Emergency Relief." Assuming that the order denying discovery in
    O'Neal is properly before us, we nevertheless hold that this
    argument also lacks merit.
    1950's, the Depot used a fourteen-acre tract of land in its
    extreme southeastern part as a landfill to dispose of various
    wastes.   The former landfill is bordered by a railroad embankment
    and the Susquehanna River to the north and by Marsh Run Creek
    ("Creek") and an access road on the south.    A drainage pipe
    carrying storm water from the Depot once emptied out onto the
    western part of the tract.    When the landfill was closed in the
    mid-1950's, Depot employees covered the debris with eighteen
    inches of dirt taken from the bank of the Creek and then spread
    coal ashes over the landfill's surface, adding another six to
    seven inches of cover.    The Depot's perimeter fence was moved
    westward so that the land, then known as Marsh Run Field, was no
    longer within the fence.    The Depot remains adjacent to the west
    end of Marsh Run Field.
    2.    Transfer of the Land to Fairview Township and
    Conversion Into a Soccer Field
    In 1970, an executive order directed the Army to
    identify and dispose of its excess acreage.    The Depot identified
    its former landfill as excess and engaged in negotiations with
    adjoining Fairview Township ("Township") officials to transfer
    the former landfill to the Township for use as a public
    recreational area, which would include soccer fields.     The land
    was formally transferred to the Township in 1976.    According to
    both Army officials and Township employee, E. Robert McCollum
    ("McCollum"), it was common knowledge that the area was once used
    as a landfill by the Depot.    Indeed, the tract was commonly
    referred to as "Pineapple Junction" because of old canned goods
    that were known to have been disposed of there.   No one from the
    Depot or the Army informed the Township that the landfill
    contained potentially hazardous or toxic substances.   Whether the
    Army knew the landfill was contaminated before the transfer is a
    point of contention.3
    In 1981, the Township began excavating and leveling the
    site, now known as Marsh Run Park ("Park"), for use as a soccer
    field.   The soccer field was completed in 1982 and was used by
    the Redland Soccer Club from 1982 until the Park was closed on
    August 28, 1987.
    3.   The Park Closure and Tests for Contamination
    In the 1960's and 1970's environmental concerns
    intensified in this nation.   New laws and regulations reflected
    3
    . This issue is the focus of plaintiffs' argument that the
    district court erred in holding that the government's deliberate
    process privilege justified the Army's refusal to disclose or
    discuss certain internal records. We discuss that issue infra in
    Part VIII of this opinion, where we conclude that the district
    court did not adequately explain the reasons for its ruling. We
    note there, however, that this discovery related not to the
    nature or toxicity of the substances the Army deposited in the
    landfill, the subject of other discovery and extensive testing,
    but rather to the Army's knowledge of their presence. That
    knowledge, or lack of it, seems to us to have little relevance to
    the plaintiffs' medical monitoring claim. See also infra
    footnote 20. We are thus satisfied that any error in this
    respect, if indeed the order refusing discovery, as opposed to
    the failure fully to explicate its rationale, is erroneous, does
    not materially affect the parties' medical monitoring claims,
    which are the subject of the claims of all plaintiffs except the
    Elliotts, who also claim standard tort damages, including damages
    for pain and suffering.
    this growing concern, and the Army began investigating how wastes
    were disposed of at its facilities.    The Depot was included.   In
    1972, the United States Army Environmental Hygiene Agency did a
    study on the Depot's wastewater discharges' effect on local
    streams and waters, including the Susquehanna River and the
    Creek, a stream which flows through the whole southern end of the
    Depot.   This study concluded that the Depot's discharges had no
    apparent deleterious impact on the Susquehanna River, but that
    they did have "a significant, adverse impact" on the plant and
    animal life in the part of the Creek lying within the Depot's
    boundaries.    In June of 1978, the Army recommended that the
    waters of the Creek within the Depot be closed to recreational
    use because low levels of polychlorinated biphenyls ("PCBs") had
    been detected in them.
    Most of the environmental studies done at the Depot
    thereafter focused on lands within the Depot and excluded the
    closed landfill, which was no longer Depot property.    In
    September of 1977, Depot officials discovered a document
    indicating a one-pound container of potassium cyanide, a toxic
    substance, had been buried in the landfill.    Depot officials
    contacted the Township and asked for permission to dig it up and
    remove it.    Depot officials were unable to locate any other
    documents detailing the contents of the landfill, and to date all
    its contents have not been identified.4

    . A United States Army Environmental Hygiene Agency Interim
    Final Report (Draft) dated December 14-17, 1987, called
    Groundwater Contamination Survey at New Cumberland Army Depot,
    listed "damaged canned goods" as the major item for disposal
    a.    Woodward-Clyde Soil Testing Report Dated July, 1987
    In 1986, the United States Army Corps of Engineers
    ("Corps") hired Woodward-Clyde Consultants ("Woodward-Clyde") to
    perform soil testing at the former landfill to see whether any
    contamination existed there.    This was done pursuant to the
    Defense Environmental Restoration Account ("DERA"), a program
    established under 
    10 U.S.C.A. § 2701
     et seq. (West 1983), to
    investigate and remedy environmental contamination at former
    Department of Defense sites.    The testing was done in March of
    1987 when the field was still being used by the Redland Soccer
    Club.
    The parameters of the study were determined by the
    Corps.    Woodward-Clyde installed three monitoring wells
    surrounding, but not on, the landfill.    It dug five test pits:
    one in the cut area on the northern edge of the Park to obtain
    background soils, one in the area of the cyanide canister burial
    and the remaining three on the field itself.    The test pits in
    the field were four to five feet in depth.    Two samples were
    removed from each pit, one near the surface and one at mid-depth.
    Surface soil samples were also taken, but not from the soccer
    (..continued)
    along with "damaged, out-of-specification or empty containers
    from such materials as napalm thickener (aluminum naphthalate
    soaps), decontaminating agent noncorrosive, decontaminating
    solution DS-2) (sic), bleaches, and clothing impregnating
    compounds (acetylene tetrachloride or chlorinated aniline in a
    chlorinated paraffin binder)." Appellants' Appendix ("App.") at
    1013a. A United States Environmental Protection Agency Report
    dated July 9, 1988 speculates that acids, solvents, fuels and
    plating solutions may also have been disposed of in the landfill.
    field area.     Groundwater was sampled in the monitoring wells,
    surface water was sampled at two locations along the site's
    boundaries and samples were obtained from in or near the Creek.
    The testing demonstrated a "significant presence of
    contaminants in some areas" of the Park and contamination in most
    of the soil and sediment samples.     Test pit soil samples
    contained organic contaminants and all surface soils contained
    elevated levels of petroleum hydrocarbons.     Groundwater samples
    contained elevated concentrations of metals.     Woodward-Clyde
    recommended further testing, including testing of the surface
    soils from the playing fields and surrounding areas "where fill
    is visible at the surface."     Appellants' Appendix ("App.") at
    950a.   Following receipt of the Woodward-Clyde report, the Army
    and the Township, by mutual agreement, closed the Park to further
    public use and the Army repossessed the land in order to conduct
    additional testing.
    b.   Corps' Public Health Evaluation Dated June 1988
    On May 25, 1988, nine months after the Park was closed
    to public use, the Corps sampled surface soils from seven areas
    on the soccer fields and one off site in an effort to determine
    whether the surface soils of the former landfill presented
    possible human health hazards.     The samples were analyzed for the
    presence of volatile organic compounds ("VOCs"), semi-volatile
    organics, PCBs, metals and cyanide.     In four of the eight
    locations low levels of polycyclic aromatic hydrocarbons ("PAHs")
    were detected.     Lead was the only metal detected at levels
    significantly above those found in the off-site sample.     The
    report considered exposure pathways of dust inhalation, skin
    contact and inadvertent ingestion of soil by hand-to-mouth
    contact.   The Corps concluded that the sampling results showed
    "no apparent increase in health risk to the children playing at
    Marsh Run Park" because the concentrations of contaminants were
    within the acceptable limits proposed by the United States
    Environmental Protection Agency ("EPA").
    c.   EPA Soil and Groundwater Sampling Report Dated July 29, 1988
    On June 11, 1988, the Army determined that the former
    landfill was an appropriate site for a remedial investigation
    study, which was also to be performed by the Corps as part of the
    Defense Environmental Restoration Program.   Meanwhile, EPA
    officials also decided to conduct soil and groundwater sampling
    at the Park and make a detailed magnetic survey.   Surface samples
    were taken by EPA on June 22 and 23, 1988 at ten on-site
    locations, stratified soil samples at three locations and
    groundwater samples at three on-site monitoring wells.     EPA
    concluded that the Park's surface soils were contaminated with
    lead and PAHs, its subsurface soils with lead and VOCs and its
    groundwater with VOCs.   The magnetic survey showed three possible
    drum burial sites in the former landfill.
    d.    EA Engineering Remedial Investigation Report Dated January
    1990
    In conducting its remedial investigation, the Corps
    contracted with EA Engineering, Science and Technology, Inc. ("EA
    Engineering").     EA Engineering agreed to identify potential
    sources of contamination, define the nature and extent of site
    contamination and any immediate offsite impact to ground water,
    surface water and air, and to assess downstream ground water and
    surface water for human health and environmental risks.      EA
    Engineering sampled waters from four nearby residential wells on
    August 31, 1989.    It sampled ground water and soils from
    monitoring wells in two separate phases in February and August of
    1989.   The record does not contain the entire EA Engineering
    Remedial Investigation Report, and it does not indicate when EA
    Engineering took the Creek surface water and sediment samples it
    analyzes in the Report.     EA Engineering did not sample the Park's
    surface soils but instead used the results of the Corps' and
    EPA's surface soils testing in May of 1988.     EA Engineering did
    not sample the waste fill itself but analyzed the surface soil
    and groundwater samples results to determine what contaminants
    might be flowing out from the waste fill.
    EA Engineering concluded that the site was contaminated
    with PAHs but that the PAHs were not unique to the site.      It
    concluded the site was also contaminated with trace metals
    including barium, lead, copper and silver.     It also determined
    the fill was a potential source of VOCs.     It found VOCs in the
    bedrock aquifer beneath the site and determined the source of
    this contamination was probably the fill.   It found low-level
    VOCs discharging to the Creek upstream from and adjacent to the
    Park, but could not confirm whether this contamination was
    resulting from ground water flowing from the fill or from some
    other source.   EA Engineering also concluded the trace metals
    were emanating partially from the fill and some other source.      It
    found no contamination in any of the residential wells, all of
    which are hydraulically upgradient from the Park.
    EA Engineering concluded that any contaminated ground
    water from the site would migrate north towards the Susquehanna
    River or flow into the adjacent Creek and that no residences are
    in the predicted migration path.   It also concluded that the
    Creek's surface waters upstream from the Park contained low-level
    volatile contaminants trichloroethane and 1,1,2,2-
    tetrachloroethane, and that the upstream sediments contained
    low-level PAHs.   The Creek's waters adjacent to and downstream
    from the Park contained low-level volatiles of trichloroethane
    and 1,2-dichlorothene.   EA Engineering concluded that the source
    of these compounds was somewhere upstream, unrelated to the Park
    and that dust from the surface soils was not a significant
    exposure pathway because the field, when tested, was covered by
    dense grass.
    As for human health risk, EA Engineering concluded that
    "the past use of Marsh Run Field as a soccer field . . . resulted
    in very little risk to the children using the field."   App. at
    1251a.   It concluded that there would be potential health risk
    from any ingestion of on-site ground water, but that such
    ingestion would be highly improbable because it was unlikely any
    residential use would be made of the site in the future.
    Finally, EA Engineering concluded there was no risk to any of the
    nearby residents because their wells were not contaminated and
    would not become contaminated in the future.    As for residents
    who may have eaten fish from the Creek, it concluded there was no
    carcinogenic risk.
    B.   The Township Worker Plaintiffs
    The Township worker plaintiffs consist of seven
    individuals who either performed the excavation and levelling
    work while the former landfill was being converted into a soccer
    field or who mowed the grass and performed maintenance work at
    the Park after the field was constructed.    Their deposition
    testimony and affidavits can be summarized as follows.
    Sometime in 1980 or 1981, Fairview Township Engineer,
    Robert G. Hartman ("Hartman"), was assigned the task of
    landscaping the former landfill for recreational use as a soccer
    field.   He conducted a topographical and perimeter survey with a
    field crew.   The Township Workers then excavated and levelled the
    land over a four month period during the summer of 1981.
    When the Township Workers first arrived at the site, it
    was covered by brush and trees and was swampy in some areas.    The
    Township Workers cleared the brush and trees and also removed
    what little topsoil was present at the site, which they put aside
    for later use.   As they began to grade the site and move earth
    from a higher section of land to the north, near the railroad
    tracks, to a lower section to the south in order to level the
    ground, they began to unearth "junk," including several barrels
    of white powder, drums, canisters, broken glass, old coffee mugs,
    utensils, cans, wood, a railroad rail and gas masks.   One of the
    Township Workers recalled someone digging test holes into the
    junk area and taking samples from them.    No one recalled any Army
    personnel being on site at any time during the work.     As
    excavation continued, the junk was covered up and used as part of
    the fill for the lower area.   The Township Workers estimated that
    a cap of an average of three feet of dirt from the higher area
    near the railroad embankment was placed over the junk.    After the
    fill was levelled, the Township Workers placed on-site topsoil
    and topsoil from off-site over the fill to a depth of two to six
    inches.   The field was then seeded.   The Township Workers
    testified they inhaled dust, waded through dirt and debris, sat
    in the dirt and ate their lunch there over the four-month period.
    One Township Worker recalled that his eyes burned or stung while
    he was running the grader and tearing up new soil and that the
    burning did not stop until the newly torn up soil was reburied.
    During the excavation and leveling work, some of these
    same Township Workers constructed a drainage swale to redirect
    water flowing out of a pipe carrying storm drainage waters out of
    the Depot.   During excavation for the swale, the Township Workers
    exposed groundwater.   Some of the Township Workers performed
    repairs on a bridge over the Creek and removed debris from the
    Creek.
    A Township Worker named David A. Kupp ("Kupp") was
    responsible for mowing the field after it was constructed.    He
    mowed once a week for approximately five hours.     Kupp recalled
    the field as dry and only sparsely covered with grass and
    remembered the mower kicking up dirt and dust from the surface of
    the field about 20% of the time.    He also spent several hours
    painting the bridge over the Creek while he stood on the banks
    and rocks and in the waters of the Creek.
    None of the Township Workers are currently suffering
    from any physical ailment that they claim is the result of their
    exposure.    There is no evidence in the record that any of them
    have been examined for health problems related to their exposure
    at the Park or that any doctor has personally informed them that
    they have an increased health risk because of exposure to toxic
    substances while working at the Park.
    C.   The Neighbor Plaintiffs
    The Neighbor Plaintiffs are twelve residents living in
    the immediate vicinity of the Park and the Creek, plus some
    relatives who regularly visited them.    Some testified in
    depositions or affidavits that they waded in the Creek, fished in
    it and ate fish they caught there.    Several testified they hunted
    in the former landfill area and ate pheasant, rabbit, squirrel or
    turtle they caught or shot there.    Most of the Neighbors used the
    Park for walking or other forms of exercise.
    On May 8, 1988, the Department of Environmental
    Resources ("DER") tested residential wells for trace metals and
    VOCs and found none of the wells were contaminated.    One
    Neighbor, however, testified that her well water was tested in
    1990 by her employer and found to contain high concentrations of
    several chemicals, including lead.    Another Neighbor testified
    that he was told his well water did not pose a health risk but
    contained traces of contaminants.    He and his family stopped
    drinking from it.   None of the Neighbors are currently suffering
    from any illness as a result of their exposure, nor have any been
    personally advised by a doctor that they have an increased health
    risk as a result of such exposure.
    D.   The Soccer Plaintiffs
    The remaining 128 plaintiffs are members of the Redland
    Soccer Association ("Redland"), adults and children who used the
    Park on a regular basis from 1982 to 1987 for soccer activities,
    and members of their immediate families who were with them during
    activities at the Park.    Some of the Soccer Plaintiffs testified
    they helped build the soccer field in 1982, picking rocks and
    moving dirt around the field and then raking and seeding it,
    setting goalposts and lining the field in order to get it ready
    for play in 1983.   This took five or six weekends with about six
    hours work per day.
    One of the Soccer Plaintiffs coached a team for
    Redland.   He testified that his team, boys sixteen years old and
    under, practiced two to three hours, three times each week at the
    Park and played one game each weekend, half at the Park.     He also
    coached a team for boys fourteen years of age and under.     That
    team also practiced three times each week and played a game once
    every weekend during the season.     Half of this team's games and
    practices were played at the Park.
    Soccer's spring season started in April of each year
    and ended in early June.     Its fall season began in mid-August and
    ended in mid-November.      Practices were canceled if it rained, but
    games were played no matter what the weather conditions were.        If
    water was on the field, someone would shovel the water away or
    throw sawdust on it.      The soccer coach recalled several players
    falling into the drainage ditch that ran the length of the field,
    which was sometimes dry and sometimes wet.     Each practice started
    with calisthenics.
    The record contains excerpts from the depositions of
    two of the soccer players.     One of them, a goalie, testified he
    often fell in the dirt around the goal area, sometimes face down
    in puddles one to two inches deep.     He also testified he
    sometimes got dirt in his mouth that he had to spit out.      Both
    players testified at times they went into the Creek to retrieve
    balls.   None of the players except Todd Elliott and his sister,
    Tracy Elliott are alleging that they are currently suffering from
    any ailment as a result of their exposure or that they have been
    personally advised by a doctor that they have an increased health
    risk due to their exposure.
    E.    The Elliott Plaintiffs
    The Elliott plaintiffs include soccer player Todd
    Elliott and his younger sister, Tracey Elliott, as well as their
    parents.   Todd played soccer at the Park and Tracey, while
    attending practices and games at the Park, skipped stones in a
    stagnant creek near the field, sat on the grass and ate food,
    crawled and ran on the field and walked through a mud-filled
    gully near the parking area.   The Elliotts allege that as a
    result of Todd's and Tracey's exposure to contaminants at the
    Park, Tracey is suffering from acute lymphocytic leukemia and
    Todd suffers from enlarged lymph nodes and an increased risk of
    cancer.5
    5
    . The Elliotts are also plaintiffs in an action against the
    Three Mile Island nuclear plant and allege their illnesses were
    caused by its release of radiation in March of 1978. See Brinser
    v. Metropolitan Edison Co., No. 481-S-88 (Pa. Commw. Ct. filed
    Feb. 1988).
    F.   The Parties' Expert Reports6
    1.   Plaintiffs' Risk Assessment
    The plaintiffs rely primarily on a report by Richard S.
    Greeley, Ph.D. ("Dr. Greeley") of R.E. Wright Associates, Inc.
    entitled "Public Health Risk Assessment of a Soccer Field Near
    the New Cumberland Army Depot, Fairview Township," dated
    January 24, 1992 ("Plaintiffs' Risk Assessment").    The
    Plaintiffs' Risk Assessment is limited to a study of the health
    risks for children and adults making use of the former landfill
    as a soccer field.    It does not address any health risks to the
    Township Workers from their excavation work or to the Neighbors
    from their recreational use of the Creek and their ingestion of
    fish and animals from the Creek and Park or water from
    residential wells.
    The Plaintiffs' Risk Assessment contains the following
    summary:
    Surface soil samples and soil samples from
    excavation of test pits on the soccer field
    have shown that volatile and semi-volatile
    organic compounds and inorganic chemical
    compounds are present in the soil. Some of
    these compounds are carcinogenic and others
    can cause adverse non-carcinogenic health
    effects. The assessment considered health
    risks arising from four primary pathways of
    exposure of the soccer players, referees and
    6
    . Because the parties on appeal do not dispute the
    admissability of any of the expert reports, we do not address the
    experts' qualifications or the reliability of their techniques or
    data, as otherwise required under our decisions In re Paoli
    Railroad Yard PCB Litigation, 
    35 F.3d 717
    , 742-49 (3d Cir. 1994)
    ("Paoli II"), cert. denied, General Electric Co. v. Ingram, 
    1995 WL 75508
     (Feb. 27, 1995), and In re Paoli Railroad Yard PCB
    Litigation, 
    916 F.2d 829
    , 855-859 (3d Cir. 1990) ("Paoli I").
    coaches to contaminant chemicals in the soil:
    (1) ingestion of contaminated soil; (2)
    ingestion of contaminated water on or near
    the field; (3) inhalation of contaminated
    dust; and (4) dermal contact with the
    contaminated soil or water.
    The risk assessment was conducted based on
    U.S. Environmental Protection Agency risk
    assessment guidance documents.
    The results of the calculations indicate that
    participation in games or practices at the
    soccer field for periods of time greater than
    33 hours results in significant health risks
    for both children and adults.
    The primary chemicals contributing to these
    risks are the inorganic chemicals arsenic and
    lead, and the base neutral polycyclic
    aromatic hydrocarbon benzo(a)pyrene. Other
    inorganic chemicals, polycyclic aromatic
    hydrocarbons, and semi-volatile organic
    compounds contribute lesser percentages to
    the risks.
    App. at 2909a.   The Report also states that increased risk may
    arise from absorption of chemicals through a cut, abrasion or
    perspiration, increased amounts of volatiles and dusts in the air
    during play and ingestion of contaminated soil or water during
    rough play when a player's face comes in contact with the ground.
    In arriving at his conclusion that adults and children
    using the field for soccer play or practice for more than
    thirty-three hours were exposed to a significant health risk, Dr.
    Greeley relied on EPA's risk assessment procedure which consists
    of four steps:   (1) data collection, evaluation and
    identification of chemicals of concern; (2) exposure assessment;
    (3) toxicity assessment and (4) risk characterization.    Risk
    characterization involves, among other things, the calculation of
    carcinogenic risks, which are stated in terms of "risk per
    million," and is arrived at by multiplying the calculated
    "increased risk of cancer" by 1,000,000.7    For each pathway of
    exposure, Dr. Greeley added together the cancer risks for each of
    the carcinogenic chemicals found at the site to derive an
    increased risk of cancer for each pathway.    He then totalled the
    risks for each pathway to arrive at a total "increased risk of
    cancer," which he defined as an increased risk of cancer due to
    exposure at the site against everyone's everyday risk of getting
    cancer.
    Using the EPA guideline that treats an increased cancer
    risk which is greater than one in a million as "significant" and
    a similar guideline for non-carcinogenic health risks, Dr.
    Greeley concluded that children or adults playing or practicing
    soccer at the Park for thirty-three hours or more had an
    increased risk of cancer of one in a million and an increased
    7
    . No one points to any demographic, epidemiologic or any other
    type of scientific data, nor to any risk-utility analysis that
    supports EPA's million-fold regulatory factor as demonstrating
    the presence of a hazard, nor does this threshold appear in the
    regulatory or statutory history. Nevertheless, the million-fold
    factor seems ubiquitous in regulatory risk-utility determinations
    despite its indeterminate pedigree. We will assume that it has
    some rational basis and thus represents a regulatory
    determination to which we must defer in deciding plaintiffs'
    statutory claims. Chevron U.S.A., Inc. v. Natural Resources
    Defense Council, 
    467 U.S. 897
     (1984); Federal Labor Relations
    Authority v. Dep't of Navy, 
    966 F.2d 747
     (1992). For purposes of
    simplicity, we will also use it to assess the tort claims. We
    note, however, that a common law court may still be free to apply
    standard tort risk-utility analysis to the problem of defining
    the threshold at which a toxic substance becomes a hazard.
    risk of non-carcinogenic health problems of three in a million
    (children) and one in a million (adults).    Children who played or
    practiced soccer at the Park for the maximum calculated exposure
    time of 1,350 hours had an increased risk of cancer of sixty-five
    in a million and of non-carcinogenic health risks of thirty-eight
    in a million.    Adults with the maximum calculated exposure time
    had an increased risk of cancer of forty-six in a million and a
    non-carcinogenic increased health risk of eleven in a million.
    In preparing his report, Dr. Greeley relied on the soil
    and groundwater sampling performed by Woodward-Clyde in March of
    1988.   Dr. Greeley also considered the soil and groundwater
    sampling results from the Corps' study performed in May of 1988
    and the EPA study performed in June of 1988, but he decided to
    rely solely on the Woodward-Clyde results because of "the non-
    homogeneity of the landfill/soccer field soil, as well as the
    difficulty in attempting to correlate samples taken at different
    depths at different times by different sampling personnel."    App.
    at 2921a.    He reasoned that the Woodward-Clyde study was the most
    representative of the three, and its sampling was performed while
    the soccer field was still in use.    He acknowledged, however,
    that Woodward-Clyde only dug three test pits within the immediate
    area of the former landfill, now the soccer field, and that the
    samples were not from the surface but were "'near-surface'"
    samples and composite samples over the four-foot depth of the
    test pits.    Therefore, he concluded "[t]he actual concentrations
    of the chemicals of concern in the soil to which the soccer
    players and adults were exposed may vary more or less from the
    values selected for this risk assessment."   App. at 2960a.   He
    also considered and rejected additional exposure routes via
    ingestion or contact with the sediments in the marsh area
    adjacent to the soccer field and the surface water of the Creek
    because the concentrations of chemicals there were either below
    the detection limits of the testing method used or no larger than
    the concentrations in the test pit soils.
    2.    Plaintiffs' Medical Monitoring Report
    The plaintiffs also rely on a report by Susan M. Daum,
    M.D. ("Dr. Daum") entitled "Medical Surveillance for Individuals
    Exposed to Hazardous Waste on Land Known as 'Marsh Run Park' in
    Fairview, Pennsylvania near the 'New Cumberland Army Depot'"
    ("Medical Monitoring Report") dated May 2, 1993.    App. at 3006a.
    There, Dr. Daum states she relies on Dr. Greeley's Risk
    Assessment and agrees with Dr. Greeley that risk levels above one
    times the background rate of one case per million is medically
    significant.    She refers to "the exposures which occurred from
    the . . . Depot and waste disposal site, whether through well
    water, or recreational activities on/in contaminated soil," as
    having a risk estimate above one in a million but does not state
    where she obtained the risk estimate for well water exposure, in
    light of the fact that Dr. Greeley did not address well-water
    exposure in his Risk Assessment.   App. at 3010a.   Ultimately, Dr.
    Daum concludes that
    the examinations [she recommends] . . . are
    not out of the ordinary, but consist of the
    usual adult medical examinations recommended
    for all adults with the adult risk of cancer
    in our society from those carcinogen
    exposures which are already prevalent. It is
    because of the increased risk of the
    exposures at the Marsh Run area, however,
    that such examinations become more urgent,
    and access to such examinations should not be
    left to vicissitudes of employment, health
    insurance contract, or other individual
    economic difficulties so prevalent in current
    health care delivery.
    App. at 3008a.   Therefore, Dr. Daum did not recommend any
    specialized tests for any of the plaintiffs but did recommend
    routine physical examinations and preventative programs.
    3.    Plaintiffs' Contributing Contaminants Report
    Finally, the plaintiffs rely on a report by Richard C.
    Cronce, Ph.D. ("Dr. Cronce") of R.E. Wright Associates, Inc.
    entitled "Evaluation Contributions of Contaminants to the
    Fairview Township Soccer Field" ("Contributing Contaminants
    Report") dated May 19, 1993.    App. at 3044.   The purpose of the
    report is "to determine the possible pathways of migration of
    regulated compounds to the surface of the soccer field, thus
    exposing persons on the field to potential adverse health effects
    from these chemicals."   
    Id.
     at 3044a.   In preparing his report,
    Dr. Cronce reviewed the various Army reports on the site and also
    performed a "site walkover" to observe present on-site
    conditions.   Id. at 3044.   The report concludes that periodic
    additions of contaminants to the surface of the soccer field are
    likely as a result of flooding, overland flow of discharge waters
    from a drainage pipe adjacent to the field, erosion of top soil
    which is revealing an underlying layer of coal ash and movement
    of the contaminants inside the landfill up to the surface soil
    either by VOCs moving up through pore space in the soil or semi-
    volatile organic compounds moving upwards as a result of
    pedoturbation, or physical soil mixing, which occurs as animals
    or insects dig or burrow in the ground.      Finally, Dr. Cronce
    concluded that because some of the topsoil used on the field
    originated from a point along the Creek, it was probably
    contaminated.
    Dr. Cronce did not perform any soil testing to confirm
    his hypotheses.      He believed, however, that "[t]he presence of
    these contaminants on the existing surface has been documented
    and, therefore, the contribution of these contaminants from these
    various processes is highly likely."      Id. at 3049a.
    4.    Elliott Plaintiffs' Expert Report
    Finally, the record contains the affidavit of Peter W.
    Wright, M.D. ("Dr. Wright"), dated April 23, 1992 regarding
    plaintiff Tracy Elliott's acute lymphocytic leukemia and
    plaintiff Todd Elliott's enlarged lymph nodes.      While preparing
    his report, Dr. Wright reviewed Tracy and Todd Elliotts' medical
    records as well as extensive scientific and medical literature
    regarding the causes of cancer and acute leukemias in particular.
    He concluded, "based on a reasonable degree of medical certainty,
    [that] the chemicals . . . found at Marsh Run Park are known to
    cause cancer, and some have been specifically implicated with
    acute leukemias, such as that which has affected Tracy Elliott.
    App. at 2233a-34a. Dr. Wright further opined that "the acute
    lymphocytic leukemia of Tracey Elliott is related to her exposure
    to the [certain] chemicals[]" [and that] "Todd Elliott, . . . due
    to his exposure to the [these] chemicals, is himself at increased
    risk of cancer."   Id.
    5.    Defendants' Expert Reports
    The defendants present a number of expert reports
    refuting plaintiffs' experts' conclusions and assumptions.
    Jessica Herzstein, M.D., M.P.H. ("Dr. Herzstein"), a physician
    specializing in occupational and environmental health, reviewed
    the Plaintiffs' Risk Assessment and the three soil sample
    analyses performed in 1987 and 1988.     She concluded that no
    medical monitoring was necessary because the plaintiffs' excess
    risk for cancer was extremely low and the risks of such tests
    outweighed the benefits.     Dr. Herzstein also produced an
    affidavit addressing Dr. Daum's Medical Monitoring Report and
    refuting its conclusion that medical monitoring was necessary for
    the same reasons given in her initial report.         Defendants also
    produced an expert report by Martyn T. Smith, Ph.D. ("Dr.
    Smith"), a toxicology specialist, who also critiqued Plaintiffs'
    Risk Assessment and concluded that the actual excess cancer risk
    posed to the Soccer Plaintiffs was zero.     Dr. Smith also
    concluded that Plaintiffs' Risk Assessment was flawed in the
    following respects: (1) it utilized unrealistic weather
    conditions; (2) it assumed an exceptionally high intake of
    surface water and soil; (3) it used test results from soil
    samples taken three to five feet below the surface; (4) it failed
    to take into account normal background levels of contaminants and
    (5) it used rodent studies for carcinogenic potency values, which
    are upper bound estimates of human potencies.   Dr. Smith also
    produced an affidavit negating Dr. Greeley's response to his
    critique of the Plaintiffs' Risk Assessment.
    James H. Jandl, M.D. ("Dr. Jandl"), a specialist in
    blood and blood disorders, reviewed Tracey Elliott's medical
    records as well as the existing literature and research in the
    fields of hematology and oncology and concluded that there is no
    medically recognized evidence linking acute lymphatic
    (lymphoblastic) leukemia to any chemical substances.    He stated
    that the only known cause of this type of leukemia is exposure to
    ionizing radiation.   He also reviewed Todd Elliott's medical
    records and concluded Todd has no medical problem with respect to
    his enlarged lymph nodes.
    Roger Minear ("Minear"), Director of the Institute for
    Environmental Studies at the University of Illinois and Professor
    of Civil Engineering, conducted a detailed review of the
    available documents concerning the Army's use of the land as a
    landfill as well as the various soil studies and remedial
    investigations reports undertaken by EPA and the Army and
    pertinent literature.   He concluded that the landfill has not
    caused surface contamination at the soccer field and that
    plaintiffs' use of the subsurface soil test results to represent
    the surface conditions on the soccer field was not realistic or
    scientifically defensible.   He also prepared a report critiquing
    Dr. Cronce's Contributing Contaminants Report, concluding that
    Dr. Cronce's hypothesized transportations of contaminants to the
    field has not been confirmed by any of the soil samples.
    Finally, defendants rely on a report by Marilyn A.
    Hewitt, P.G. ("Hewitt"), a certified professional geologist and
    former Pennsylvania DER hydrogeologist.   Hewitt reviewed
    Plaintiffs' Risk Assessment, as well as the soil test reports and
    other environmental investigation reports at the Park, maps,
    photographs, depositions and correspondence.   She concluded that
    the exposure assumptions made in the Plaintiffs' Risk Assessment
    were not consistent with standard EPA protocols for evaluating
    human exposure to contaminants when the use of the contaminated
    property is recreational, such as a soccer field.   She found the
    Plaintiffs' Risk Assessment was erroneous primarily because it
    utilized test results from soils as deep as three feet below the
    surface, whereas the standard EPA protocol called for use of
    surface soil samples no more than one foot deep.    She also found
    the Risk Assessment failed to average the concentrations of
    contaminants in the soil samples and calculated the health risks
    using the maximum concentrations of contaminants, also contrary
    to standard EPA protocol.   Therefore, she concluded that the
    Plaintiffs' Risk Assessment contained an inflated estimate of the
    health risks associated with the soccer field.   She also examined
    Dr. Cronce's Contributing Contaminants Report and, using the
    available soil testing results, refuted Dr. Cronce's assumptions
    regarding contaminants being contributed from other contaminated
    areas of the Creek or Depot.   She refuted Dr. Cronce's conclusion
    that the surface soils were contaminated by upward transport by
    volitization of contaminants within the landfill based on the
    "insignificant" concentrations of such chemicals in the soils at
    the Park.    App. at 3223a.    Finally, Hewitt refuted Dr. Cronce's
    assumption that pedoturbation had caused mixing of the surface
    soils with the contaminated subsurface soils based on the fact
    that the surface soils were tested after the field had been
    closed for use as a soccer field.
    Both Dr. Greeley and Dr. Cronce submitted affidavits
    responding to defendants' experts' critiques of their reports.
    II.     Procedural History
    On June 7, 1990, five of the plaintiffs filed a class
    action complaint ("Redland complaint") seeking (1) injunctive
    relief and money damages under the Federal Tort Claims Act
    ("FTCA"), 
    28 U.S.C.A. § 2671
     et seq. (West 1994), for remedial
    action, medical monitoring and emotional distress ("Redland FTCA
    Plaintiffs"); (2) injunctive relief and response costs under the
    Comprehensive Environmental Response, Compensation, and Liability
    Act ("CERCLA"), 
    42 U.S.C.A. § 9601
     et seq. (West Supp. 1994), in
    the form of remedial action, medical monitoring and reimbursement
    of plaintiffs' litigation costs; (3) injunctive relief under the
    Pennsylvania Hazardous Sites Cleanup Act ("HSCA"), 
    35 Pa. Cons. Stat. § 6020.101
     et seq. (West 1993), in the form of remedial
    action, monetary damages and reimbursement of plaintiffs'
    litigation costs and (4) monetary damages for diminution of the
    Neighbors' property values based on trespass.      On February 26,
    1991, the Elliotts filed a complaint under the FTCA alleging
    negligence and seeking monetary damages for past and future
    medical expenses, pain and suffering, medical monitoring and
    litigation costs.     The district court consolidated these cases on
    September 30, 1993.
    The district court denied class certification for the
    Soccer Plaintiffs, Neighbors and Township Workers on March 4,
    1991.   After the plaintiffs' motion for reconsideration was
    denied on May 3, 1991, they filed an amended complaint joining an
    additional one hundred forty-five plaintiffs (collectively
    "Redland Plaintiffs") on August 26, 1991.
    On December 12, 1991, the United States moved to
    dismiss plaintiffs' claims for medical monitoring and injunctive
    relief pursuant to Federal Rule of Civil Procedure 12(b)(6).    On
    February 12, 1992, the district court granted the motion in part,
    and dismissed the Redland Plaintiffs' request for a medical
    monitoring fund under CERCLA.     The court also dismissed all of
    the Redland Plaintiffs' FTCA claims requesting injunctive relief.
    On March 27, 1992, the United States moved for
    dismissal of the Elliotts' complaint and for summary judgment.
    On June 23, 1992, the district court granted the motion in part
    and entered summary judgment in favor of the United States on all
    claims except medical monitoring, which it then left for trial.
    On June 4, 1992, the United States moved for summary
    judgment or, in the alternative, partial summary judgment on the
    amended Redland complaint.    On September 15, 1992, the district
    court granted the motion in part and dismissed the Redland
    plaintiffs' citizen suits under CERCLA and HSCA claims for lack
    of subject matter jurisdiction.   The court also granted summary
    judgment to the United States and dismissed the Redland
    Plaintiffs' claims for attorneys' fees and experts' fees under
    CERCLA and for attorneys' fees under the HSCA.    The court did not
    address the Redland Plaintiffs' entitlement to expert fees under
    HSCA.   The court denied the United States' request for partial
    summary judgment based on sovereign immunity, and denied the
    motion in all other respects.
    On January 25, 1993, the United States moved to dismiss
    the Redland Plaintiffs' FTCA claims for lack of subject matter
    jurisdiction and, in a separate motion, asked for summary
    judgment on all of the plaintiffs' claims for medical monitoring
    and emotional distress, including the Elliotts' medical
    monitoring claim.   On June 1, 1993, all plaintiffs moved for
    partial summary judgment.   On October 19, 1993, the district
    court denied the United States' motion to dismiss but granted its
    motion for summary judgment on all plaintiffs' medical monitoring
    and emotional distress claims and entered judgment against
    plaintiffs on those claims.   It therefore denied plaintiffs'
    motion for partial summary judgment.
    During the proceedings in the district court, the
    parties became embroiled in a number of discovery disputes which
    the district court resolved in the United States' favor and which
    plaintiffs now challenge on appeal.    These include (1) an order
    dated January 14, 1991 denying plaintiffs' motion to compel
    discovery and sustaining the United States' objections to several
    interrogatories; (2) an order dated August 13, 1992 denying
    plaintiffs' motion to compel the production of one hundred
    thirty-nine documents and sustaining the United States' assertion
    of the Deliberative Process Privilege; (3) an order dated
    January 29, 1993 denying plaintiffs' motion to compel the
    production of five documents and sustaining the United States'
    assertion of the Deliberative Process Privilege; (4) an order
    dated March 4, 1993 granting the United States' motion for a
    protective order concerning plaintiffs' notices of deposition and
    (5) an order dated November 16, 1993 denying plaintiffs' motion
    for emergency relief concerning defense counsel's contact with
    former Army employees who were potential witnesses for the
    plaintiffs.
    On November 29, 1993, the court entered final judgment
    in favor of the United States and against the plaintiffs.    On
    December 23, 1993 plaintiffs filed a timely notice of appeal.
    III.   Jurisdiction and Standard of Review
    The district court had subject matter jurisdiction
    pursuant to 
    28 U.S.C.A. §§ 1331
    , 1346 (West 1993) and 
    28 U.S.C.A. § 2671
     (West 1994), as well as CERCLA, 
    42 U.S.C.A. § 9613
    (b)
    (West 1983).    It had supplemental jurisdiction over the
    plaintiffs' state law claims pursuant to 
    28 U.S.C.A. § 1367
     (West
    1993).   We have appellate jurisdiction pursuant to 
    28 U.S.C.A. § 1291
     (West 1993).
    In reviewing an order granting summary judgment, we
    exercise plenary review.    Viewing the facts in the light most
    favorable to the nonmoving party, we look to see if there was a
    genuine issue of material fact; and, if not, whether the moving
    party was entitled to judgment as a matter of law.    See Fed. R.
    Civ. P. 56; Anderson v. Liberty Lobby, Inc., 
    477 U.S. 242
    , 249-50
    (1986); In re Paoli R.R. Yard PCB Litigation, 
    916 F.2d 829
    , 860
    (3d Cir. 1990) ("Paoli I").
    We review de novo the district court's determination
    that the Redland Plaintiffs were not entitled to response costs
    under CERCLA and HSCA, including a health risk assessment, expert
    fees, attorney fees and other costs.    See United States v.
    Hardage, 
    982 F.2d 1436
    , 1446 (10th Cir. 1992).    Finally, we
    generally review the court's discovery rulings for abuse of
    discretion.    See Marroquin Manriquez v. I.N.S., 
    699 F.2d 129
    , 134
    (3d Cir. 1983), cert. denied, 
    467 U.S. 1259
     (1984).
    Nevertheless, we exercise de novo review over the standards the
    district court used in exercising its discretion.    We find an
    abuse of discretion only if there is either an interference with
    a substantial right or a gross abuse that could result in
    fundamental unfairness at trial.     
    Id.
     (citations omitted).
    IV.    Plaintiffs' Claims Under FTCA
    A.   Medical Monitoring
    We will first address the Redland FTCA Plaintiffs'
    argument that they presented sufficient evidence to the district
    court to withstand a motion for summary judgment on their FTCA
    claim that the Army's negligence entitles them to medical
    monitoring.   In Paoli I, supra, we concluded that the
    Pennsylvania Supreme Court would recognize a cause of action for
    medical monitoring for plaintiffs who have been exposed to
    various toxic substances.     See Paoli I, 
    916 F.2d at 852
    .     In so
    concluding, we set forth four factors a plaintiff must prove in
    order to recover:
    1.   Plaintiff was significantly exposed
    to a proven hazardous substance through the
    negligent actions of the defendant.
    2.   As a proximate result of exposure,
    plaintiff suffers a significantly increased
    risk of contracting a serious latent disease.
    3.   That increased risk makes periodic
    examinations reasonably necessary.
    4.   Monitoring and testing procedures
    exist which make the early detection and
    treatment of the disease possible and
    beneficial.
    
    Id.
       We stated that these factors must be proven by competent
    expert testimony.     
    Id.
     (citation omitted).     We did not, however,
    define the term "significantly exposed" or state what details an
    expert must testify to in order to establish it.
    We recently revisited this issue in In re Paoli
    Railroad Yard PCB Litigation, 
    35 F.3d 717
     (3d Cir. 1994),
    (Paoli II), cert. denied, General Electric Co. v. Ingram, 
    1995 WL 75508
     (Feb. 27, 1995) .     There, we noted a New Jersey Supreme
    Court decision which held that plaintiffs seeking recovery for
    medical monitoring must "'have . . . experienced direct and hence
    discrete exposure to a toxic substance[.]'"     
    Id. at 787
     (quoting
    Theer v. Philip Carey Co., 
    628 A.2d 724
    , 733 (N.J. 1993)).      Theer
    held a plaintiff who was exposed to asbestos while laundering her
    husband's clothes could not bring a medical monitoring claim
    because, in part, "it was too difficult to quantify her
    exposure."    
    Id.
       We noted our uncertainty regarding the impact of
    Theer, but believed Pennsylvania courts would not adopt such a
    narrow view of the cause of action.     We reasoned that "[s]omeone
    indirectly exposed to one chemical might have as much risk of
    disease as someone directly exposed to another chemical[.]"      
    Id. at 787-88
    .    Accordingly, we declined to adopt a "per se rule
    requiring direct exposure, actual injury, and testimony about an
    individual's particular level of exposure."     
    Id. at 788
    .
    Nevertheless, we predicted that the Pennsylvania
    Supreme Court would set some limits on a medical monitoring
    claim, and we therefore adopted the Utah Supreme Court's holding
    in Hansen v. CCI Mechanical, Inc., 
    858 P.2d 970
    , 980 (Utah 1993).
    We stated that:
    In order for a plaintiff to show significant
    exposure that causes a significantly
    increased risk to plaintiff of contracting a
    serious disease that makes periodic testing
    reasonably necessary, we think that a
    plaintiff must:
    prove that by reason of the
    exposure to the toxic substance
    caused by the defendant's
    negligence, a reasonable physician
    would prescribe for her or him a
    monitoring regime different from
    the one that would have been
    prescribed in the absence of that
    particular exposure. This is
    because under this cause of action,
    a plaintiff may recover only if the
    defendant's wrongful acts increased
    the plaintiff's incremental risk of
    incurring the harm produced by the
    toxic substance enough to warrant
    a change in the medical monitoring
    that otherwise would be prescribed
    for that plaintiff.
    Hansen v. CCI Mech., Inc., 
    858 P.2d 970
    , 980
    (Utah 1993). The court continued:
    [I]f a reasonable physician would
    not prescribe it for a particular
    plaintiff because the benefits of
    the monitoring would be outweighed
    by the costs, which may include,
    among other things, the burdensome
    frequency of the monitoring
    procedure, its excessive price, or
    its risk of harm to the patient,
    then recovery would not be allowed.
    
    Id. at 788
    .   "Significant exposure," therefore, refers to an
    exposure which, either by duration or harm, is sufficient to
    cause a significantly increased risk, which in turn is sufficient
    to require a monitoring regime different from that normally
    required in the absence of such an exposure.
    Here, in order to establish the first Paoli I factor of
    significant exposure, the district court reasoned that plaintiffs
    must show by clear evidence that they were actually exposed to
    toxins.   The district court noted that "[t]here is, of necessity,
    a degree of speculation in a medical monitoring case.
    However, . . . the allowable conjecture should be in regard to
    the amount or future effect of the exposure, not whether there
    was exposure at all."    Redland Soccer Club Inc. v. Dep't of Navy,
    No. 90-1072, slip op. at 14-15 (M.D. Pa. Oct. 19, 1993).     After
    reviewing plaintiffs' expert reports, the district court
    concluded that nowhere did plaintiffs' experts unequivocally
    state that plaintiffs had actually been exposed to any of the
    toxins alleged to be in the Park's soils or that any of the
    toxins had actually entered any of the plaintiffs' bodies.    The
    district court's conclusion was based on plaintiffs' failure to
    present any evidence that the surface soils of the Park contained
    a level of contamination harmful to human beings.
    The district court's analysis focuses perceptively on
    an issue we believe is central in all toxic tort cases; namely,
    the requirement that the alleged wrong create some significant
    risk of harm to the plaintiff.   Thus, a plaintiff must not only
    show exposure, but must prove that he was exposed beyond what
    would normally be encountered by a person in everyday life, so
    that the plaintiff's risk of being injured from the exposure is
    greater, in some way, than the normal risks all of us encounter
    in our everyday lives.   In Paoli II, we chose not to delve into
    the issues of how much exposure there had to be to equal
    "significant exposure", nor how "direct" the exposure must be.
    Instead, we simply required the plaintiff to prove indirectly the
    nature of the exposure by requiring him to show an "injury"
    (e.g., a need for medical monitoring greater than that what is
    required by all persons).8
    We do not believe, however, that the Redland FTCA
    Plaintiffs' failure to produce evidence, in the form of blood or
    tissue tests, showing directly that they absorbed toxins from the
    field into their bodies is fatal to their claims.   Defendants'
    own expert stated generally that there are no medical tests which
    8
    . The injury requirement is particularly important before a
    remedy such as medical monitoring is provided because the
    plaintiff's injury is only an increased possibility of harm
    rather than actual harm. Paoli II's requirement of "special"
    medical monitoring implicitly recognizes the longstanding
    requirement in all tort cases other than those based on the old
    "intentional" common law torts for various forms of trespass that
    a plaintiff must prove an injury before he may recover anything
    from a defendant. See Gideon v. Johns-Manville Sales Corp., 
    761 F.2d 1129
    , 1136 (5th Cir. 1985) ("An actionable tort, whether
    based on negligence or strict liability consists of two elements:
    a failure to act in accordance with the standard of care required
    by law and a resultant injury . . . . However egregious the
    legal fault, there is no cause of action for negligence . . .
    until there is 'actual loss or damage resulting to the interests
    of another.'") (citations omitted). Otherwise, a polluter would
    become a health care insurer for medical procedures routinely
    needed to guard persons against some of the ordinary vicissitudes
    of life. It would convert toxic torts into a form of specialized
    health insurance. Imposition of liability on this basis seems to
    go beyond current tort theories of negligence or strict liability
    by requiring a polluter to pay for medical procedures that the
    general population should receive. Thus, Paoli II requires
    plaintiffs to show not only that their exposure to toxic
    substances is greater than normal background levels, but that the
    increased risk of injury from such exposure warrants medical
    monitoring against future illness beyond that which is
    recommended for everyone. See Paoli II, 
    35 F.3d at 788
    .
    could have detected the presence of the toxins found at the Park,
    and even if a test existed which could have detected a particular
    toxin, it would have been useful only if it were conducted within
    one hundred twenty days of the plaintiffs' exposure.   App. at
    82a.   Requiring a plaintiff to produce this kind of evidence to
    support a finding of exposure to a toxic hazard would place an
    impossible burden on persons subjected to serious medical risk
    from toxic substances polluters have left to contaminate the
    environment and afflict the people who live near the wrongdoer's
    waste deposits.   Thus, even without this direct evidence, we
    believe plaintiffs may still satisfy the first Paoli I factor
    through expert testimony showing they were exposed to the toxins
    at issue at levels significantly above their normal background
    presence so as to require special tests or more frequent medical
    monitoring than medicine recommends for the general population.
    With this in mind, we turn to the Redland FTCA Plaintiffs' expert
    reports to see whether any of them have produced evidence
    sufficient to survive summary judgment on their medical
    monitoring claims.
    Surprisingly, we discover the record has no expert
    opinion on whether either the Township Workers or the Neighbors
    have been exposed to toxins to such an extent that they suffer
    such an increased risk of contracting a serious disease that
    supplemental medical testing is reasonably required.   Of all the
    Redland Plaintiffs, the Township Workers who excavated and
    levelled the contaminated landfill for four months would appear
    to have the highest potential for significant exposure to toxins.
    Yet plaintiffs' experts virtually ignore them, as well as the
    Neighbors, and focus their expert opinion almost exclusively on
    the soccer players, who would seem to have suffered a more
    limited risk of significant exposure, given the paucity of
    evidence in this record showing there were harmful quantities of
    contaminants in the surface soils of the playing field.   Our
    review of the expert reports presented by the parties, as well as
    the soil testing analyses, indicates that the subsurface of the
    landfill was contaminated; but neither the EPA's nor the Corps'
    surface soil test results indicate contamination in the surface
    soil above background levels.   It is undisputed that the soccer
    players' primary exposure for any substantial length of time was
    only to the surface soils on the soccer field.   Without evidence
    showing that the surface was contaminated, the Soccer Plaintiffs
    cannot show significant exposure.
    Dr. Greeley's report relies solely on the
    Woodward-Clyde soil samples which were taken at some depth below
    the surface of the Park, and he acknowledges that the exposure
    values selected for use in the risk assessment may vary from the
    actual concentrations in the soil.   Nevertheless, we believe that
    Dr. Greeley's report, as well as Dr. Cronce's report in which he
    concluded that contaminants from the subsurface could migrate
    upwards into the surface and that flooding of the Creek could
    spread contaminants on the surface, permit a reasonable
    factfinder to infer that adults and children using the soccer
    field for thirty-three hours or more were exposed to carcinogens
    and non-carcinogens that increased their risk of illness beyond
    the one-in-a-million benchmark the EPA uses to measure
    significant risk.9
    Turning to the Redland FTCA Plaintiffs' evidence
    concerning special medical monitoring, the only expert report
    concerning the need for and extent of medical monitoring is that
    of Dr. Daum.   She expressly states that she does not recommend
    special testing for any of the plaintiffs:10
    I emphasize . . . that the examinations
    suggested [below] are not out of the
    ordinary, but consist of the usual adult
    medical examinations recommended for all
    adults with the adult risk of cancer in our
    society . . . . It is because of the
    increased risk of the exposures at the Marsh
    Run area, however, that such examinations
    become more urgent, and access to such
    examinations should not be limited to
    vicissitudes of employment, health insurance
    contract, or other individual economic
    difficulties . . . .
    She acknowledges the considerable limitations of the currently
    known examinations and tests for the early detection of cancer,
    as well as the fact that some, such as lung cancer screening,
    create risks that outweigh the potential benefits.   She also
    9
    . We again note, however, that Dr. Cronce's report is not based
    on any study quantifying the actual effects of this hypothetical
    migration. We also note again that EPA's basis for its use of
    the one-in-a-million lifetime ratio to judge significant exposure
    is not readily apparent. Nevertheless, we will assume a rational
    basis for EPA's one-in-a-million standard in defining
    "significant" risk. See supra footnote 7.
    10
    . Dr. Daum does not distinguish between the different groups
    of Redland Plaintiffs. Rather, she refers simply to them as the
    "individuals" exposed to contaminants at the Park. App. at
    3006a.
    declines to recommend any specific surveillance tests for any
    other non-cancerous chronic diseases, for the same reasons.
    (App. 3011)
    Thus, because all the Redland FTCA Plaintiffs (the
    Township Workers, the Neighbors and the Soccer Players) failed to
    introduce evidence that their exposure required a different
    medical monitoring regimen than that which would normally be
    recommended for them absent exposure, under Paoli II, we will
    affirm the district court's order granting summary judgment to
    the United States on the Redland FTCA Plaintiffs' medical
    monitoring claims.
    B.    Emotional Distress
    The Redland FTCA Plaintiffs also seek to recover
    damages for negligent infliction of emotional distress caused by
    their exposure to chemicals at the Park.   The record shows that
    none of the Redland FTCA Plaintiffs currently suffer a physical
    injury or a medically-identifiable effect from any exposure to
    chemicals at the Park.    Therefore, we conclude the district court
    did not err in granting summary judgment to the United States on
    this aspect of plaintiffs' claim.   Absent some physical injury or
    impact, Pennsylvania's governing law does not provide recovery
    for negligent infliction of emotional distress.    See Wisniewski
    v. Johns-Manville Corp., 
    759 F.2d 271
    , 274 (3d Cir. 1985) (citing
    Cathcart v. Keene Indus. Insulation, 
    471 A.2d 493
    , 508 (Pa.
    Super. Ct. 1984)); see also Bubash v. Philadelphia Elec. Co., 
    717 F. Supp. 297
    , 300 (M.D. Pa. 1989) (mere exposure not equivalent
    to physical injury).
    We also believe the district court correctly
    distinguished Merry v. Westinghouse Elec. Corp., 
    684 F. Supp. 847
    (M.D. Pa. 1988).   There, the court held that plaintiffs'
    emotional distress claims survived Westinghouse's summary
    judgment motion because the plaintiffs' experts testified that
    plaintiffs suffered a present "physical effect as a result" of
    exposure to contaminated well water and that some plaintiffs
    "demonstrated acute physical symptoms of exposure to the
    chemicals."   
    Id. at 852
    .   We have no such expert evidence here.
    Therefore, summary judgment against the Redland FTCA Plaintiffs
    on their emotional distress claims was appropriate.11
    V.   The Redland Plaintiffs' Claims Under CERCLA
    We turn next to the Redland Plaintiffs' argument that
    the district court erred in dismissing their claims for response
    costs, including attorneys fees, expert witness fees and health
    11
    . The Redland FTCA Plaintiffs also argue the district court
    erred in dismissing their FTCA request for remedial action under
    CERCLA and HSCA. This remedy is not available against the United
    States under FTCA, and we will affirm the district court's order
    dismissing it. See, e.g., Hatahley v. United States, 
    351 U.S. 177
    , 182 (1956) (district court did not possess power under FTCA
    to enjoin United States); Moon v. Takisaki, 
    501 F.2d 389
    , 390
    (9th Cir. 1974) (per curiam) (FTCA does not submit United States
    to injunctive relief). Accordingly, we need not, and do not
    consider whether the district court correctly denied the Redland
    FTCA Plaintiffs' motion for summary judgment on their claim of
    negligence per se against the United States.
    risk assessment costs, under CERCLA.    We conclude that the
    district court correctly dismissed these response cost claims.12
    Although the Redland Plaintiffs acknowledge the
    existence of an ongoing remedial action at the site, they contend
    that the remedial action "is not even attempting to address the
    health risks created by the contaminated site," and therefore
    their request for expert fees, costs of health risk assessments
    and other costs are not "challenges" to the remedial action.
    Brief for Appellants at 17.    They also contend their action is an
    action for response costs, which is not subject to CERCLA's
    prohibition against private remedial actions.   See 
    42 U.S.C.A. § 9613
    (h) (West Supp. 1994).
    Under CERCLA, there are at least two theories on which
    a private individual can base an action for response cost.
    First, a person who has incurred response costs that were
    necessary and consistent with the national contingency plan
    12
    . Initially, we note that the Redland plaintiffs also contend
    that the district court erred in dismissing their claim for
    medical monitoring under CERCLA. We believe that the elements of
    a claim for medical monitoring under CERCLA and HSCA are the same
    as the elements for a common law medical monitoring claim set out
    in Paoli I and Paoli II. Because of our conclusion that the
    Redland FTCA Plaintiffs failed to introduce sufficient evidence
    to survive a summary judgment motion on their FTCA medical
    monitoring claim, we need not and do not address whether they
    could recover medical monitoring costs from the United States as
    a "response cost" under CERCLA or HSCA. We also note that the
    United States Supreme Court recently held that attorneys fees
    are not recoverable as response costs under CERCLA. See Key
    Tronic Corp. v. United States, 
    114 S. Ct. 1960
    , 1967 (1994).
    Thus, as the Redland Plaintiffs concede, we must affirm the
    district court's order dismissing their request for attorneys
    fees under CERCLA.
    ("NCP"), has a private right of action under 
    42 U.S.C.A. § 9607
    (a)(4)(B) (West Supp. 1994).    Second, any person may bring
    a civil action on his own behalf in the proper district court
    against any person, including the United States or its agencies,
    for violations of CERCLA or against the President or the
    Administrator of EPA for their failure to perform any act or duty
    arising under CERCLA.   See 
    42 U.S.C.A. § 9659
    (a) (West Supp.
    1994); see also Key Tronic Corp., 
    114 S. Ct. at 1965-66
    .
    The district court's jurisdiction over such actions is
    limited as follows:
    No Federal Court shall have jurisdiction
    under Federal law other than under section
    1332 of Title 28 (relating to diversity of
    citizenship jurisdiction) or under [relevant]
    State law . . . to review any challenges to
    removal or remedial action selected under
    section 9604 of this title, or to review any
    order issued under section 9606(a) of this
    title, in any action except one of the
    following:
    (1) An action under section 9607 of
    this title to recover response costs or
    damages or for contribution.
    . . .
    (4) An action under section
    9659 of this title (relating to
    citizen suits) alleging that the
    removal or remedial action taken
    under section 9604 of this title or
    secured under section 9606 of this
    title was in violation of any
    requirement of this chapter. Such
    an action may not be brought with
    regard to a removal where a
    remedial action is to be undertaken
    at the site.
    
    42 U.S.C.A. § 9613
    (h)(1), (4) (West Supp. 1994).13
    The absence of a definition of "response costs" has
    been the source of much litigation since CERCLA's enactment.    The
    terms "response" and "respond" are defined as "remove, removal,
    remedy, and remedial action," including enforcement activities.
    
    42 U.S.C.A. § 9601
    (25) (West Supp. 1994).    "'[R]emedial action'
    means those actions consistent with permanent remedy taken
    instead of or in addition to removal actions in the event of a
    release or threatened release of a hazardous substance into the
    environment, to prevent or minimize the release of hazardous
    substances . . . ."   
    42 U.S.C.A. § 9601
    (24) (West Supp. 1994) (in
    relevant part). The terms "remove" or "removal" means:
    the cleanup or removal of released hazardous
    substances from the environment, such actions
    as may be necessary taken in the event of the
    threat of release of hazardous substances
    into the environment, such actions as may be
    necessary to monitor, assess, and evaluate
    the release or threat of release of hazardous
    substances, the disposal of removed material,
    or the taking of such other actions as may be
    necessary to prevent, minimize or mitigate
    damage to the public health or welfare or to
    the environment, which may otherwise result
    from a release or threat of release.
    
    42 U.S.C.A. § 9601
    (23) (in relevant part).
    13
    . The Redland Plaintiffs argue the district court incorrectly
    limited its analysis to section 9613(h)(1), (4) in dismissing
    their CERCLA claims. Nevertheless, when we look to section 9659,
    we see that the issues still to be decided on this appeal do not
    involve either of the kinds of claims that can support a
    citizen's suit alleging a removal or remedial action undertaken
    or secured by or through EPA. The Redland Plaintiffs do not
    contend otherwise. Therefore, we focus our analysis on the first
    exception to section 9613(h).
    We do not believe the Redland Plaintiffs' litigation
    costs are "response costs" under any of these definitions.      The
    health risk assessment and expert testimony were designed to
    assess, for litigation purposes, what health risks, if any, the
    plaintiffs were exposed to while using the Park for recreation.
    The expert assessments were conducted long after the Park was
    closed to recreational use and have nothing to do with any
    remedial or response action at the Park itself.    Moreover, under
    section 9607, plaintiffs may only recover response costs which
    are necessary and consistent with the NCP.    See 
    42 U.S.C.A. § 9607
    (a)(4)(B).   The heart of these definitions of removal and
    remedy are "'directed at containing and cleaning up hazardous
    releases. . . .    [T]herefore[,] . . . 'necessary costs of
    response' must be necessary to the containment and cleanup of
    hazardous releases."   United States v. Hardage, 
    982 F.2d 1436
    ,
    1448 (10th Cir. 1992) (health assessments conducted by experts
    retained for litigation purposes not response costs under section
    9607(a)(4)(B)), cert. denied, Advance Chemical Co. v. U.S., 
    114 S. Ct. 300
     (1993); see Cook v. Rockwell Int'l Corp., 
    755 F. Supp. 1468
    , 1476 (D. Colo. 1991) ("A plaintiff who has incurred no
    costs, except for litigation expenses, prior to the filing of a
    CERCLA action has incurred no 'necessary costs of response' under
    § 9607(a)."); Ambrogi v. Gould, Inc., 
    750 F. Supp. 1233
    , 1246
    (M.D. Pa. 1991) (health assessments not recoverable response
    costs under CERCLA).    Therefore, we do not believe the district
    court erred in determining that plaintiffs' costs are not
    response costs because they are not "monies . . . expended to
    clean up sites or to prevent further releases of hazardous
    chemicals."   Redland Soccer Club Inc. v. Dep't of Navy, No. 90-
    1073, slip op. at 5 (M.D. Pa. Sept. 15,, 1992).14
    VI.   Summary Judgment against Elliotts
    Finally, we consider the Elliotts' claims.    They
    challenge the district court orders dismissing their FTCA
    negligence claim against the Army in which they seek damages for
    medical monitoring, past and future medical expenses, pain and
    suffering and emotional distress.   The district court held that
    the Elliotts, like the other plaintiffs, had produced no evidence
    they were actually exposed to chemicals at the Park.    We
    concluded in Section IV.A. that there is enough evidence to
    create a genuine issue of material fact as to whether persons
    using the Park for thirty-three hours or more had enough exposure
    to carcinogens and non-carcinogenic toxins to create a
    significant risk to their health.   Nevertheless, we affirmed the
    district court's order granting summary judgment to the
    government on the claims of the Township Workers, the soccer
    players and the Neighbors for medical monitoring because they had
    failed to show that their exposure made any medical monitoring
    14
    . The Redland Plaintiffs also argue that the district court
    erred in dismissing their citizen suits for injunctive and
    remedial relief, as well as attorneys fees, expert fees and
    health risk assessment costs under HSCA. In view of our
    disposition, we need not decide that issue. We note, however,
    that the test of HSCA is markedly different from that of CERCLA.
    We express no opinion, however, about any claim for medical
    monitoring under state law.
    tests or examinations necessary or desirable other than those
    that health care professionals recommend for people who have had
    no exposure to any of the toxic substances that might be found at
    the Park.
    The Elliotts' case differs in a striking respect from
    the other plaintiffs in this action:    Tracey Elliott suffers from
    leukemia and Todd Elliott suffers from enlarged lymph nodes.
    None of the other Redland Plaintiffs show any signs of physical
    injury from their exposure.    Accordingly, the Elliotts have shown
    harm because the illnesses of their children demonstrate an
    immediate need for medical monitoring beyond that which is
    recommended for the general population.    Still, neither their
    common law tort claim nor any of their statutory claims can
    survive unless they establish their exposure is the cause of
    their increased medical needs.    The district court held that Dr.
    Wright's statement that the Elliott children's illnesses were
    "related to" their exposure to the health hazards at the Park
    that resulted from the Army's deposit of toxic substances there
    was insufficient to show causation under applicable Pennsylvania
    law.   We believe the conclusion that the Elliotts have failed to
    show causation, as a matter of law, should not have been made at
    this stage of the proceeding on the record before the district
    court.
    In order to establish a traditional tort claim for
    negligence under Pennsylvania law, the Elliotts must establish
    that the Army's failure to exercise reasonable care towards them
    and any breach of its duty exposed them to an elevated risk of
    foreseeable harm, which resulted in injury.15   Mohler v. Jeke,
    
    595 A.2d 1247
     (Pa. Super. Ct. 1991).    On this record, we think
    the question whether the Elliotts can successfully establish all
    these elements of their claim is a question of fact, not law.      At
    this stage, we look only to see if the Elliotts have introduced
    enough evidence to create a genuine issue of material fact as to
    each of these elements, including causation, the only one still
    at issue.    For the following reasons, we conclude they have.
    We note initially that "cause in fact," or physical
    cause, is not the same as "proximate cause," or legal cause, and
    that both must be shown.   See Bell v. Irace, 
    619 A.2d 365
    , 367
    (Pa. Super. Ct. 1993); Novak v. Jeanette Dist. Mem. Hosp., 
    600 A.2d 616
    , 618 (Pa. Super. Ct. 1991).    Causation in fact is
    normally a question for the jury, but proximate cause poses
    questions of law which require the court to determine whether the
    defendant's negligence was so remote that, as a matter of law, he
    cannot be held liable for the harm which subsequently occurred.
    See Bell, 
    619 A.2d at 367
    ; Novak 
    600 A.2d at 618
    .   Of course,
    under Pennsylvania law, the exposure must appear to contribute
    15
    . The parties agree that Pennsylvania law governs all state
    law issues in this case. We believe causation is an issue that
    should be determined by state law on all the theories of recovery
    the Elliotts assert. Paoli II, 
    35 F.3d at 717
    . Like the
    district court, we recognize that violation of a statute or
    administrative regulation may be negligence per se, and therefore
    a higher degree of care may be required in handling dangerous or
    toxic materials. The principles of negligence per se aid
    plaintiffs in establishing a breach of duty, but they do not
    avoid the issue of causation. The basic elements of any
    negligence claim remain a duty, breach of the duty, actual loss
    or harm and a causal connection between the breach and the harm.
    See Casey v. Geiger, 
    499 A.2d 606
    , 612 (Pa. Super. Ct. 1985).
    "substantially" to the Elliotts' injuries, but this is an issue
    of degree that is usually a question for the factfinder.16     See
    Paoli II, 
    35 F.3d at
    761 n.31 (citing Hamil v. Bashline, 
    392 A.2d 1280
    , 1284 (1978) (discussing Pennsylvania's "substantial" factor
    requirement on proving causation).
    The district court believed that Dr. Wright's statement
    that the Elliott children's illnesses was "related to," rather
    than "caused by," any assumed exposure failed to show a causal
    connection between Tracey's exposure and her leukemia.     It relied
    on Novak v. United States, 
    865 F.2d 718
     (6th Cir. 1989), in
    rejecting Dr. Wright's report and thus analyzed Dr. Wright's
    report in terms of proximate cause, rather than "but for" cause
    or causation in fact.     In Novak, an expert testified that
    plaintiff's death was "related" to a swine flu vaccination he
    received.   
    Id. at 720
    .    This medical opinion was based on the
    expert's assumption that the disease plaintiff suffered was
    caused by a virus.   Tellingly, "no witness for the plaintiff
    could say with scientific or medical certainty that the
    particular vaccine at issue . . . caused [plaintiff's] disorder."
    
    Id. at 722
    .    Considered along with the defendant's expert
    testimony that there was no scientific evidence that the vaccine
    was related to the cause of plaintiff's illness, the United
    States Court of Appeals for the Sixth Circuit concluded that the
    16
    . Of course, if it could be shown, by cross-examination or
    otherwise, that Dr. Wright used the term "relation" to mean
    "correlation" in the statistical sense instead of cause in either
    the medical or legal sense, the force of his testimony could be
    significantly affected.
    district court clearly erred in upholding a finding of causation
    and entering judgment for the plaintiff.   
    Id.
    On this appeal, however, we are reviewing the Elliotts'
    claims at the summary judgment stage, and on that basis alone
    Novak is distinguishable.   Whether Dr. Wright's testimony will
    persuade the factfinder that leukemia is caused by toxins of the
    type found at the Park remains to be seen.   For summary judgment
    purposes, however, we believe that the Elliotts have introduced
    sufficient evidence to establish a genuine issue of material fact
    regarding causation. Dr. Wright testified:
    It has been stated in a standard text of
    oncology that irradiation and exposure to
    toxic chemicals are the most studied
    environmental factors that predispose to
    leukemia. In another standard text of cancer
    epidemiology, it has also been stated that
    the probable causes of leukemia include a
    range of factors, acting singly or in
    combination, some involving intrinsic host
    mechanisms and others reflecting
    environmental exposures, including radiation,
    chemicals and others.
    App. at 2190a. Dr. Wright continued:
    Some of the chemicals found on [NCAD]
    includ[ing] . . . but not restricted to
    arsenic, cadmium, trichloroethylene,
    chloroform, DDT, PCBS, carcinogenic PAHs,
    hexachlorobenzene, radium, and
    pentachlorophenol.
    Lymphoreticular malignancies in humans have
    been linked to exposure to benzene,
    chloroform, chlorophenols, and
    trichloroethylene. Animal studies have also
    supported a causal relationship between
    exposure to trichloroethylene, DDT, and
    benzene and lymphoreticular malignancy in
    animals. A positive statistical association
    of childhood leukemia and well water
    contaminated with chlorinated organics,
    including trichloroethylene chloroform has
    been reported. An increased leukemia
    mortality has been attributed to occupational
    exposure to chemicals, including organic
    solvents, and chlorophenols, all chemicals
    known to be present at Marsh Run Park.
    
    Id.
     at 2191a.   In contrast to Novak, Dr. Wright also testified,
    "based upon a reasonable degree of medical certainty," some of
    the chemicals at the Park cause cancer, including acute leukemia,
    and Tracey Elliott's disease is related to her exposure at the
    Park.   
    Id.
     at 2233a.17
    Under Paoli II, 
    35 F.3d at 750-52
    , the requirement of
    expert testimony on issues of the type involved here is a matter
    of substantive law governing a plaintiff's burden of proof.
    However, Pennsylvania caselaw on causation does not require that
    expert testimony include any "magic words" such as "caused by,"
    rather than "related to."   To the extent that "magic words" have
    any significance in the Pennsylvania cases, they seem merely to
    reflect Pennsylvania's sensible requirement that the expert speak
    "with a reasonable degree of medical certainty."   In Gradel v.
    Inouye, 
    421 A.2d 674
    , 679 (Pa. 1980), for example, the Supreme
    Court of Pennsylvania held:
    Expert medical opinion on causation need not
    be unqualified and absolute, i.e., stated in
    'categorical terms;' ordinarily, it must
    17
    . Of course, if it could be shown, by cross-examination or
    otherwise, that Dr. Wright used the term "relation" to mean
    "correlation" in the statistical sense instead of cause in either
    the medical or legal sense, the force of his testimony could be
    significantly affected.
    establish that the injury was, to a
    'reasonable degree of medical certainty,'
    caused by the alleged negligence.
    [When] the complexities of the human
    body place questions as to the cause of pain
    or injury beyond the knowledge of the average
    layperson . . . the law requires that expert
    medical testimony be employed. In addition
    to its bearing on whether or not the
    defendant's conduct was negligent, such
    testimony is needed to establish that the
    injury in question did, with a reasonable
    degree of medical certainty stem from the
    negligent act alleged.
    
    Id.
     (quoting Hamil v. Bashline, 
    392 A.2d 1280
    , 1285 (Pa. 1978)
    (emphasis omitted from original and added)).   We believe Dr.
    Wright spoke with the "reasonable degree of medical certainty"
    required by Pennsylvania caselaw.
    The district court also concluded that Dr. Wright's
    report did not sufficiently "rebut" the affidavit submitted by
    the Army's expert, Dr. Jandl, stating that leukemia is not caused
    by the types of chemicals found at the Park and that Tracey's
    leukemia and Todd's enlarged lymph nodes therefore cannot be
    causally linked to their exposure.   Dr. Wright's report stated
    that Tracey Elliotts' leukemia is related to her exposure to the
    chemicals found at the Park and that Todd Elliott has an
    increased risk of cancer due to his exposure to the same
    chemicals.   It also states that exposure to certain chemicals,
    including those found at the Park, is among the risk factors
    associated with leukemia.   Dr. Wright and Dr. Jandl simply
    reached different conclusions regarding the cause of the Elliott
    children's injuries after reviewing the Elliotts' medical
    records.   Because their opinions conflict as to the fact of
    causation, there remains a genuinely disputed issue of material
    fact on the issue of causation, which is for the factfinder to
    resolve.   It is up to the jury to decide whether the chemicals at
    the Park were a substantial contributory cause of the Elliott
    children's illnesses.   Viewing the evidence in the light most
    favorable to the Elliotts, the nonmoving party, we believe Dr.
    Wright's report is enough to permit the Elliotts to survive the
    United States' motion for summary judgment on the issue whether
    Todd and Tracey Elliotts' present injuries, including any need
    for special medical monitoring, has been caused by their exposure
    to any toxic substances the Army may have deposited in the
    landfill under the Park in which they played.
    VII.   Discovery Disputes
    Because we will reverse the district court's order
    granting   summary judgment to the United States on the Elliotts'
    claims, we must consider the discovery issues the appellants
    raise concerning the district court's decision that the
    deliberate process privilege enabled the United States to
    withhold discovery of certain documents that could be relevant or
    likely to lead to the discovery of relevant information.    The
    plaintiffs appeal three discovery related orders, issued by the
    district court, which denied their motions to compel production
    of documents.18
    A.   The Deliberative Process Privilege
    First, the plaintiffs allege that the district court's
    order, dated August 13, 1992, denying their motion to compel
    production of one hundred thirty-nine documents based upon the
    defendants' deliberative process privilege, was an abuse of
    discretion.   The deliberative process privilege permits the
    government to withhold documents containing "confidential
    deliberations of law or policymaking, reflecting opinions,
    recommendations or advice."   In re Grand Jury, 
    821 F.2d 946
    , 959
    (3d Cir. 1987) (citing NLRB v. Sears Roebuck & Co., 
    421 U.S. 132
    ,
    150-54 (1975); EPA v. Mink, 
    410 U.S. 73
    , 89 & n.16 (1973)), cert.
    18
    . The plaintiffs also challenge the district court's order,
    dated March 4, 1993 granting the defendants' motion to require
    the plaintiffs to travel to the residence or place of business of
    certain witnesses who were sought to be deposed. The plaintiffs
    contend that it was an abuse of discretion to require them to
    send an attorney there to conduct the depositions and that the
    district court should have ordered the depositions to occur at
    the site of the litigation. In the end, the plaintiffs deposed
    these individuals by phone and so did not incur the travel
    expense to which they objected. The plaintiffs now claim this
    was unfair because they were unable "to evaluate the appearance
    and conduct of [the] witnesses." Reply Brief of Appellants at
    22. We cannot say, based on this generalized complaint, that the
    district court's order was an abuse of discretion. See
    Marroquin-Manriquez v. I.N.S., 
    699 F.2d 129
    , 134 (3d Cir. 1983),
    cert. denied, 
    467 U.S. 1259
     (1984) (a district court has broad
    discretion in determining the manner in which discovery is
    conducted.).
    denied sub. nom., Colafella v. United States, 
    484 U.S. 1025
    (1988).19
    "[T]he ultimate purpose of this long-recognized
    privilege is to prevent injury to the quality of agency
    decisions."     Sears, Roebuck & Co., 
    421 U.S. at 151
    .    It
    recognizes "that were agencies forced to operate in a fishbowl,
    the frank exchange of ideas and opinions would cease and the
    quality of administrative decisions would consequently suffer."
    First Eastern Corp. v. Mainwaring, 
    21 F.3d 465
    , 468 (D.C. Cir.
    1994) (quotations and internal ellipses omitted).      The
    deliberative process privilege does not protect factual
    information, even if such information is contained in an
    otherwise protectable document, as long as the information is
    severable.    See In re Grand Jury, 
    821 F.2d at 959
    .     In addition,
    it does not protect "[c]ommunications made subsequent to an
    agency decision."    United States v. Farley, 
    11 F.3d 1385
    ,     1389
    (7th Cir. 1993).
    The privilege, once determined to be applicable, is not
    absolute.    First Eastern Corp., 21 F.3d at 468 n.5; Farley, 
    11 F.3d at 1389
    .    After the government makes a sufficient showing of
    entitlement to the privilege, the district court should balance
    19
    . Our discussion of the deliberative process privilege is
    based, in part, on interpretations of the bank examination
    privilege. The two privileges are similar and precedent
    concerning them is often relied upon interchangeably. See, e.g.,
    Schreiber v. Society for Savings Bancorp, Inc., 
    11 F.3d 217
    , 220-
    22 (D.C. Cir. 1993); In re Subpoena Served Upon the Comptroller
    of the Currency and the Secretary of the Board of Governors of
    the Federal Reserve System, 
    967 F.2d 630
    , 634 (D.C. Cir. 1992).
    the competing interests of the parties.    The party seeking
    discovery bears the burden of showing that its need for the
    documents outweighs the government's interest.    This Court has
    previously stated that "the party seeking disclosure may overcome
    the claim of privilege by showing a sufficient need for the
    material in the context of the facts or the nature of the case .
    . . or by making a prima facie showing of misconduct."   In re
    Grand Jury, 
    821 F.2d at 959
     (internal citations omitted).       The
    United States Court of Appeals for the District of Columbia,
    recently determined that a district court, in balancing the
    interests, should consider at least the following factors:
    "(i) the relevance of the evidence sought to be protected;
    (ii) the availability of other evidence; (iii) the 'seriousness'
    of the litigation and the issues involved; (iv) the role of the
    government in the litigation; [and] (v) the possibility of future
    timidity by government employees who will be forced to recognize
    that their secrets are violable."    First Eastern Corp., 21 F.3d
    at 468 n.5.
    Thus, a party's assertion of the deliberative process
    privilege requires a two-step review in the district court.
    First, it must decide whether the communications are in fact
    privileged.    Second, the court must balance the parties'
    interests.    Because the district court did not sufficiently
    explain its rationale in either respect, we will vacate its order
    of August 13, 1992 denying the plaintiffs' motion to compel
    discovery of the 139 documents which the Army claimed the
    deliberative process privilege.20    On remand, the district court
    should demonstrate its adherence to the process.
    The initial burden of showing privilege applies is on
    the government.   See Schreiber v. Society for Savings Bancorp.,
    
    11 F.3d 217
    , 221 (D.C. Cir. 1993).    To meet it, the government
    must present more than a bare conclusion or statement that the
    documents sought are privileged.     
    Id.
       Otherwise, the agency, not
    the court, would have the power to determine the availability of
    the privilege.    
    Id.
    The United States, in support of its assertion of the
    deliberative process, initially gave the district court a list
    and description of fifty-nine requested documents which
    plaintiffs had requested with supporting affidavits.      There it
    states that all the documents fall within one of three
    categories:   "1) [d]raft documents intended only for internal
    review; 2) comments on draft documents; and 3) internal, pre-
    decisional notes and memoranda recommending courses of agency
    action."   App. at 1900.   The affidavit then states in general
    terms that the documents in each category are within the purview
    20
    . Our remand on these discovery related orders does not affect
    our affirmance of summary judgment against the plaintiffs who
    were unable to show an injury. The discovery that was denied
    sought information on violations of law, the defendants'
    knowledge, overall contamination, etc. See App. at 2334-37.
    These issues go to breach of duty, or violation of law, not to
    the special monitoring that might be necessary from the exposure
    involved here. See also supra footnote 3. Unlike the other
    plaintiffs, the Elliotts and their children seek damages beyond
    medical monitoring and have produced evidence showing present
    illness, not just future risk of harm.
    of the privilege.21   The listing provided some benefit to the
    district court in its description of the documents, but the
    detail given in the various descriptions varies.   The description
    given for most of the documents withheld provides little more
    than general information indicating which of the three general
    categories the documents fall into.   For example, one document is
    described as "August 1990 draft New Cumberland Army Depot
    Remedial Investigation/Feasibility Study of the AMSCS."
    21
    . The entire argument the United States presented to the
    district court follows:
    An essential element in the effective
    management of the Army's environmental
    program at Army installations is the
    assurance that the Army, its contractors, and
    other reviewing agencies may engage in free
    and candid discussions while formulating Army
    positions, arriving at Army decisions, and
    preparing final versions of Army documents.
    Draft documents and the comments on draft
    documents listed in attachment 1 are an
    integral part of the deliberational,
    predecisional processes that results in a
    final Army decision. Editorial changes that
    would be apparent fr[o]m a comparison of the
    draft to the final document reflect the
    personal opinions and mental impressions of
    the drafting and editing staff. Disclosure
    of draft documents and comments on drafts
    would stifle the editing process and impair
    the frank presentation of ideas that
    accompanies the drafting and finalization of
    Army documents. Disclosure would, therefore,
    result in an identifiable harm to the public
    interest, namely an impairment of the
    decision making process would result in
    prejudice to the Army's goal of making the
    best possible decisions and producing the
    best possible documents.
    App. at 1900-01.
    Approximately two months after the filing of the initial
    affidavit and document list, the defendants presented the
    district court with a second affidavit, verbatim except for the
    different date, and a listing of an additional 82 documents for
    which the defendants wished to invoke the privilege.   The
    descriptions of these documents were similarly conclusory.
    Before this Court, both the United States and the
    Elliotts dispute the reasoning behind the district court's order.
    The Elliotts rely on the district court's use of the phrase
    "compelling reason" in its order to argue that the court erred by
    applying a "compelling reason test."   The United States points to
    the court's use of the word "outweighs" to argue that the
    district court applied the correct balance in the exercise of its
    discretion.  The district court stated:
    It is understandable that plaintiffs may
    wish access to this material but they state
    no specific or compelling reason to obtain
    any particular item. Based upon our review
    of the arguments made and authorities cited
    we believe the need to protect the
    predecisional, deliberative process in
    government decision making outweighs the
    general desire of plaintiffs to view this
    material as part of discovery.
    App. at 2402.
    We are reluctant, on this record, to decide just what
    the district court meant by the use of any particular word or
    phrase.   Instead, we think the district court should, on remand,
    apply the balancing test as we have outlined it.   It should also
    make any findings of fact that may be needed to support its
    implicit conclusion that the documents sought fell under the
    deliberative process privilege, if it so decides on remand.       See
    Comptroller of the Currency, 
    967 F.2d at 636
     (Although the
    district court used the language of balancing, "[n]either the
    order nor the . . . hearing that preceded it indicates with any
    clarity, [] the factors that persuaded the court to [reach] this
    conclusion."); In re Grand Jury, 
    821 F.2d at 959
    .
    The district court may elect to perform a preliminary
    in camera review of the documents in question before balancing
    the competing interests and exercising its discretion.    In In re
    Grand Jury, we referred to the Supreme Court's statement in Kerr
    v. United States District Court, 
    426 U.S. 394
    , 406 (1976), that
    "in camera review is a highly appropriate and useful means of
    dealing with claims of governmental privilege."     In re Grand
    Jury, 
    821 F.2d at 959
    .22
    22
    . See also In re Franklin Natl. Bank Securities Litig., 478
    F. Supp. at 582 ("Given this clash of strong competing interests,
    the official information privileged usually requires examination
    of documents in camera."); Northrop v. McDonnell Douglas Corp.,
    
    751 F.2d 395
    , 405 (D.C. Cir. 1984) ("The litigant's need for the
    information cannot be balanced against its sensitive and critical
    role in the government's decision making process without any
    indication of what that information is.").
    The plaintiffs also contend that the district court erred by
    not considering whether the government committed illegal acts,
    the fact that the government is alleged to be a tortfeasor, that
    the individual who characterized the documents could not
    objectively evaluate their deliberative content, that the
    government failed to persuasively show the potential harm from
    disclosure and that the government failed to adequately describe
    the documents. We believe these tests tend to beg the privilege
    question.
    In considering the United States' assertion of
    privilege, the district court should keep in mind the fact that
    Federal Rule of Civil Procedure 26 authorizes broad discovery
    into "any matter, not privileged, which is relevant to the
    subject matter involved in the pending action, [see Federal Rule
    of Civil Procedure 26(b)(1)] but the deliberative process
    privilege, like other executive privileges, should be narrowly
    construed."    See Coastal States Gas Corp. v. Dep't. of Energy,
    
    617 F.2d 854
    , 868 (D.C. Cir. 1980); Cooney v. Sun Shipbuilding &
    Drydock Co., 
    288 F. Supp. 708
    , 716 (E.D. Pa. 1968) (collecting
    cases).
    B.   Waiver of the Privilege
    The plaintiffs also attack the district court's order,
    dated January 29, 1993, denying their motion to compel discovery
    of five documents.    In this respect, they claim, even if the
    documents were privileged, that the United States has waived its
    privilege.    Waiver is based on the Army's disclosure of these
    five documents in the course of a subsequent response.    The
    district court concluded that this disclosure was "inadvertent"
    and did not qualify as a "voluntary" waiver.    App. at 2621.     See
    Transamerica Computer Co. v. International Business Machines
    Corp., 
    573 F.2d 646
    , 651 (9th Cir. 1978).    The district court did
    not err when it rejected the plaintiffs' waiver argument.
    We also reject the plaintiffs' contention that the
    importance of the documents should be factored into the
    determination of whether the government waived its privilege.
    The importance of the documents is relevant to the balancing of
    interests, but the plaintiffs refer us to no cases and we find
    none stating that it is relevant to waiver.   Moreover, we believe
    the importance of the documents is immaterial to whether their
    disclosure was voluntary.
    C.   Relevance
    Finally, the plaintiffs challenge the district court's
    order, dated January 14, 1991, regarding their attempt to compel
    discovery against the Army's contention that the Privacy Act, 5
    U.S.C.A. § 552a(b)(11) (West 1995), covered some of the
    plaintiffs' requests.   In this order, the district court held
    that the Privacy Act did not protect the discovery sought, but
    denied some of the requested discovery as overbroad or
    burdensome.   The plaintiffs contend that the court failed to
    apply the standards this court requires in deciding whether a
    discovery request is overbroad or burdensome.     See Josephs v.
    Harris Corp., 
    677 F.2d 985
    , 992 (3d Cir. 1982).    The United
    States responds with a footnote in its brief, stating:
    The basis for appealing this order is unclear
    given the fact that the district court
    required the United States to supply
    plaintiffs with information which otherwise
    would have been protected by the Privacy Act,
    5 U.S.C. § 552a(b)(11). This Court should
    reject the appeal because plaintiffs have
    failed to show how the district court abused
    its discretion.
    Brief of Appellees at 41 n.22.
    In Josephs, we stated "the mere statement by a party
    that the interrogatory was overly broad, burdensome, oppressive
    and irrelevant is not adequate to voice a successful objection to
    an interrogatory."    Josephs, 
    677 F.2d at 992
     (internal quotations
    omitted).   Instead, "the party resisting discovery must show
    specifically how each interrogatory is not relevant or how each
    question is overly broad, burdensome or oppressive."       
    Id.
    (citations, internal ellipses and internal quotations omitted).
    The record before us has only the district court's
    order which states its conclusion that the discovery requests
    were "overbroad and burdensome."     App. at 1507.   On remand the
    district court might wish to set forth its recognition and use of
    the Josephs standards in support of its conclusion that the
    plaintiffs' request for some documents be overturned.
    VIII.   Conclusion
    The order of the district court dismissing the claims
    of the Neighbors, the Soccer Plaintiffs and the Township Workers
    will be affirmed.    Its order granting the United States summary
    judgment on the Elliotts' claims will be reversed, and their case
    will be remanded for further proceedings consistent with this
    opinion.
    The parties shall each bear their own costs.
