    COURT OF APPEALS
    THIRTEENTH DISTRICT OF TEXAS
    CORPUS CHRISTI - EDINBURG
    IN RE: ALLIED CHEMICAL CORPORATION, ET AL.
    On Petition for Writ of Mandamus
    OPINION
    Before Chief Justice Valdez and Justices Garza and Benavides
    Opinion by Justice Garza
    In September 1999, hundreds of plaintiffs sued more than thirty defendants, seeking
    damages for a vast array of injuries allegedly caused by a “toxic soup” of pesticides
    released into the community from facilities in Mission, Texas, operated by Hayes-
    Sammons Chemical Co. (“Hayes-Sammons”) between 1950 and 1967. Nine years after
    the suit was initiated, the claims of one plaintiff, Guadalupe Garza, have been severed and
    set for trial.
    In a petition for writ of mandamus filed on April 16, 2008,1 the defendants,2
    comprised mostly of manufacturers and suppliers of the chemicals used in the pesticide

    facilities, ask us to order the trial court to grant their motions for summary judgment and
    their fourth motion to compel discovery. In a separate petition filed on November 25,
    2008,3 the defendants ask us to compel the trial court to vacate its orders severing Garza’s
    claims and setting them for trial. We deny both petitions in part and conditionally grant the
    writs in part.
    I. BACKGROUND
    Multiple petitions for writ of mandamus have been filed with this Court by the
    defendants in this case. In 2004, the defendants asked us to compel the trial court to
    vacate its order consolidating five plaintiffs’ claims and setting them for trial, asserting that
    those plaintiffs had not timely provided adequate discovery responses. We denied the
    petition. In re Allied Chem. Corp., No. 13-04-00491-CV, 2004 Tex. App. LEXIS 9931, at
    *1-2 (Tex. App.–Corpus Christi Nov. 4, 2004, orig. proceeding) (per curiam) (mem. op.).
    In a five-to-four decision, the Texas Supreme Court subsequently granted mandamus
    relief, noting that “in mass tort cases involving hundreds of parties and complicated
    causation questions, a trial judge could not postpone responses to basic discovery until
    shortly before trial.” In re Allied Chem. Corp., 
    227 S.W.3d 652
    , 655 (Tex. 2007) (orig.
    proceeding) (citing Able Supply Co. v. Moye, 
    898 S.W.2d 766
    , 772 (Tex. 1995)); but see
    
    id. at 664
    (Jefferson, J., dissenting) (noting that plaintiffs had already supplemented their
    discovery responses and mandamus was inappropriate because the case was moot). The
    plaintiffs have since repeatedly amended their discovery responses. Whereas the 2004
    petition was concerned with the timeliness of plaintiffs’ responses, we are now called upon
    to evaluate, among other things, the adequacy of those responses.
    The defendants first served their master set of interrogatories on plaintiffs on
    November 12, 2001. The master set included the following Interrogatory 20, known as the
    Able Supply interrogatory:
    Please state the name and address of each and every doctor, physician,
    3
    Appellate cause num ber 13-08-00678-CV.
    2
    psychiatrist, psychologist, counselor, or other medical practitioner who has
    attributed your alleged injury made the basis of this lawsuit to exposure to
    the Defendants’ products or Defendants’ conduct, including the dates of
    treatment or examination of each such doctor, physician, or other medical
    practitioner, and the name or identity of the products to which your alleged
    injury is attributed.
    See Able 
    Supply, 898 S.W.2d at 768
    (mandating trial court to compel mass tort plaintiffs
    to answer similar interrogatory).4
    On June 25, 2002, the defendants filed their first motion to compel, seeking an order
    compelling the plaintiffs to answer Interrogatories 15 (asking plaintiffs to identify the
    product or products that caused their injuries), 16 (asking which defendants produced the
    products that caused their injuries), 17 (asking which facility was the source of the products
    that caused their injuries), and 20 (the Able Supply interrogatory).5 The trial court granted
    this motion on October 29, 2002, ordering the plaintiffs “to provide full, complete, and
    plaintiff-specific answers to Interrogatories 15, 16, 17, and 20” on or before December 2,
    2002.
    On December 2, 2002, the plaintiffs supplemented their answers to the
    interrogatories. In response to Interrogatories 15 and 16, the plaintiffs provided a general
    list of products produced by each defendant. The response did not indicate which plaintiffs
    had been exposed to which products. In response to Interrogatory 17, the plaintiffs
    identified “the Hayes-Sammons faciliti(es) located in Mission, Texas” as the location from
    which the products causing their injuries originated.
    In response to the Able Supply interrogatory, the plaintiffs stated that “none of their
    treating physicians have told them that their health condition(s) are or were attributable to
    their exposure” to defendants’ products. The response to Interrogatory 20 also included
    an expert report authored by Sandra Mohr, M.D., stating that “most primary care physicians
    4
    Plaintiffs’ initial responses to the m aster set of interrogatories are not contained in the record before
    us.
    5
    According to defendants, the plaintiffs had previously objected to Interrogatories 15, 16, 17 and 20
    as “overly broad, harassing, unduly burdensom e, seek[ing] inform ation that is neither relevant nor likely [to]
    lead to the discovery of adm issible evidence and ... constitute[] an im perm issible fishing expedition.”
    3
    are not prepared by virtue of their clinical training to assign a chemical etiology to the
    diagnosis of a disease and that Occupational and Environmental Medicine physicians are
    the most appropriate specialists to determine chemical etiology of a disease.”
    The defendants then filed a second motion to compel on April 26, 2004, again
    asking the trial court to compel “plaintiff-specific” answers to the Able Supply interrogatory.
    The trial court granted this second motion as well, ordering all plaintiffs to “supplement
    Interrogatory No. 20 (i.e., the Able Supply Interrogatory) . . . in accordance with the Court’s
    October 29, 2002 Order.” In response, the plaintiffs filed supplemental Able Supply
    answers on July 19, 2004, which consisted of a three-page affidavit authored by Michael
    Wolfson, M.D., a physician trained in occupational and environmental medicine. Dr.
    Wolfson’s affidavit was accompanied by a 1,848-page chart entitled “Exhibit A,” which
    listed each individual plaintiff’s symptoms and the pesticides produced at the Hayes-
    Sammons plant which could have caused those symptoms. The chart included references
    to academic literature which Dr. Wolfson claimed supported his assertions that the various
    chemicals could cause the various symptoms. An example of one plaintiff’s entry on the
    chart is as follows:

    Zivot (1993)
    Dr. Wolfson noted in his affidavit that the chart provided only a general statement
    4
    about which pesticides could produce certain symptoms, and that it did not purport to make
    any specific statements about causation regarding any individual plaintiff. Specifically, Dr.
    Wolfson stated:
    Exhibit “A”, attached to this affidavit, is a summary of my opinions. My
    opinions at this time are limited to the general causation of medical harm by
    pesticides (i.e. whether a pesticide is capable of causing a particular disease,
    condition or injury) and not specific causation (i.e. whether a pesticide, in
    fact, caused a plaintiff’s disease, condition or injury).
    Subsequently, on August 9, 2004, the trial court granted a motion filed several
    months earlier to consolidate five plaintiffs’ claims and set them for trial. Trial was set for
    the five plaintiffs—Irma Gomez, Sandra Aguero, Noelia O. Morales, Garza, and Jose Maria
    Solis—for February 14, 2005.
    Certain defendants then moved for no-evidence summary judgment on September
    9, 2004, claiming that the plaintiffs had still not adequately answered the Able Supply
    interrogatory. Certain other defendants filed a third motion to compel with the trial court
    seeking to compel an adequate response. At a hearing on November 22, 2004, the trial
    court denied both motions.
    On February 14, 2005, four of the five trial plaintiffs—Garza, Morales, Gomez and
    Solis—filed an additional supplemental response to Interrogatory 20, identifying nine
    experts that would testify on their behalf at trial:        a hematologist/oncologist, two
    toxicologists, a civil engineer, an industrial hygienist, two environmental engineers, an
    epidemiologist, and a former DuPont research chemist.
    On March 3, 2005, defendants Aventis CropScience USA (“Aventis”) and Maxus
    Energy Corp. (“Maxus”) filed no-evidence and traditional motions for summary judgment,
    contending that they never sold or delivered any of the pesticides at issue in the case to
    the Hayes-Sammons facility.
    Subsequently, on June 15, 2007, the Texas Supreme Court granted mandamus
    relief to all defendants, directing the trial court “to vacate its order setting any of the
    plaintiffs’ claims for trial until the defendants have a reasonable opportunity to prepare for
    5
    trial after learning who will connect their products to plaintiffs’ injuries.” In re Allied Chem.
    
    Corp., 227 S.W.3d at 659
    . The Court found specifically that the defendants were entitled
    to adequate responses to the Able Supply interrogatory establishing the causation element
    of their claims. Moreover, the Court noted that mandamus was an appropriate remedy
    because: (1) making thirty defendants “prepare in the dark for 1,900 claims is far out of
    proportion to the benefit of giving the plaintiffs more time (after five years) to decide who
    or what injured them”; (2) allowing discovery to continue to thirty days before trial amounts
    to a “denial of discovery . . . go[ing] to the very heart of this case”; and (3) “the plaintiffs’
    intention to withhold responses until shortly before [trial] meant the defendants could not
    prepare a viable defense.” 
    Id. at 658
    (citing Able 
    Supply, 898 S.W.2d at 771
    , 772). In
    response, on July 17, 2007, the defendants filed a fourth motion to compel answers to the
    Able Supply interrogatory, asking the trial court to mandate “complete and plaintiff-specific
    responses,” and to order that a failure to so respond by any plaintiff within 30 days “shall
    result in severance and dismissal with prejudice.”
    One week prior to its decision in In re Allied Chemical Corp., the Texas Supreme
    Court handed down Borg-Warner Corp. v. Flores, 
    232 S.W.3d 765
    (Tex. 2007), which
    addressed the adequacy of causation evidence in an asbestos exposure case. The Borg-
    Warner court held that, in order to establish causation, the plaintiff must provide
    “[d]efendant-specific evidence relating to the approximate dose to which the plaintiff was
    exposed, coupled with evidence that the dose was a substantial factor in causing the
    asbestos-related disease.” 
    Id. at 773.
    In response to this decision, the defendants in the
    instant case propounded an additional interrogatory on plaintiffs on July 2, 2007, asking
    the following:
    For each Defendant listed in Plaintiffs’ Thirteenth Amended Petition or any
    Defendant listed in a previous petition that has settled, please provide:
    a.        The approximate dose of each product manufactured or sold by each
    Defendant to which Plaintiff was exposed that is alleged to have
    caused harm to Plaintiff;
    b.        The methodology used to calculate the dose; and
    6
    c.      Evidence that the dose was a substantial factor in causing the harm
    to Plaintiff.
    After over two months, having failed to receive an answer to this interrogatory—which the
    defendants style “the Borg-Warner interrogatory”—the defendants filed a motion to compel
    an answer with the trial court.
    On September 11, 2007, Garza provided an amended Able Supply answer,
    including reports authored by the nine experts identified in the earlier response. In one
    report, Frank Gardner, M.D., a clinical professor of medicine, concluded after reviewing
    Garza’s hospital and clinical records that: “[Garza] lived in the vicinity of the [Hayes-
    Sammons] facility, and had prolonged exposure to pesticides. The chronic exposure to
    high risk levels of organochlorine pesticides were the cause, with more probability than not,
    for [her] onset of non-Hodgkins lymphoma.” In another report, William R. Sawyer, Ph.D.,
    a toxicologist, calculated Garza’s exposure doses of organochlorine pesticides and
    concluded:
    I am certain, to within a reasonable degree of toxicological certainty that Ms.
    Garza’s chronic exposures to DDT, dieldrin, BHCs, and toxaphene released
    from Hayes-Sammons significantly contributed to the onset of her NHL [non-
    Hodgkin lymphoma]. My review of her historical medical records, direct
    interview, and inspection of her 1016 Nicholson Street home failed to provide
    any other significant occupational or environmental exposures contributing
    to the onset of her NHL.
    On October 9, 2007, Garza provided an amended answer to the so-called Borg-
    Warner interrogatory. The response included detailed calculations of the amount of the
    chemicals to which Garza was exposed. The response included precise estimates as to
    Garza’s exposure to each of the chemicals based on dermal absorption, inhalation, and
    ingestion of dust and soil, and concluded that Garza had been exposed to the following
    doses6:
    6
    The response stipulated that the total dose levels were “[u]nderestim ated value[s]” because of
    “unavailable inhalation data [and] oral fruit and vegetable ingestion [data]” and that “household dust derm al
    absorption” was not included in the figures.
    7
    DDT                       2.2 × 10-4 mg/kg/day
    Dieldrin                  1.95 × 10-4 mg/kg/day
    BHC                       1.1 × 10-2 mg/kg/day
    Toxaphene                 2.0 × 10-5 mg/kg/day
    Garza’s October 9, 2007 supplemental response also contained a list identifying
    certain defendants which, she alleged, provided the specific pesticides that caused her
    injuries. The list, included as a supplemental response to defendants’ Interrogatory 16,
    stated:
    Guadalupe Garza supplements this response and identifies the following
    manufacturers and/or distributors of the pesticides and the specific
    pesticides sold or otherwise distributed to Hayes-Sammons and which are
    the cause of her Non-Hodgkins’ Lymphoma:
    COMPANY                                          CHEMICAL(S)
    Allied Chemical Corporation                      BHC, DDT
    Aventis Cropscience USA                          BHC
    Holdings, Inc. d/b/a Aventis
    Cropscience USA
    Maxus Energy Corporation                         DDT
    f/k/a Diamond Shamrock
    Corporation
    [etc.] . . .
    Accompanying Garza’s amended responses was a motion to sever her claims and a
    request to set her claims for trial.
    At a hearing on October 10, 2007, the trial court considered the motion for summary
    judgment filed by Aventis and Maxus, the defendants’ fourth motion to compel an adequate
    Able Supply answer, the defendants’ motion to compel Borg-Warner answers, as well as
    Garza’s motion for severance and request for trial setting. At the hearing, the plaintiffs
    conceded that they are obligated to answer the Borg-Warner interrogatory, but merely
    argued that they ought to be given the opportunity to do so “on a rolling basis rather than
    all 1,800 at once.” The defendants, on the other hand, argued that not only was Dr.
    Wolfson’s affidavit and chart insufficient to adequately answer the Able Supply
    8
    interrogatory on behalf of the non-trial plaintiffs, but also that Garza’s supplemental
    responses to the Able Supply and Borg-Warner interrogatories were inadequate because
    they are not “defendant-specific.” After hearing argument, the court granted the plaintiffs’
    motion to sever Garza’s claims on December 11, 2007, and took the motion for summary
    judgment and the two defendants’ motions to compel under advisement.7
    Subsequently, on October 18, 2007, Garza filed a second set of supplemental
    answers to the interrogatories, including a report by Marco Kaltofen, a professional
    engineer, which attempted to ascertain the source of the chemicals identified in the Borg-
    Warner response as causing Garza’s injuries. Kaltofen’s report referenced historical sales
    records, audit records, and deposition testimony, and concluded:
    In summary based on the manufacturing and distribution history of the
    defendants, the evidence of sales to Hayes Sammons and the testing
    results, it is my opinion that the following manufacturers supplied the
    identified products to the Hayes Sammons facility during the time period in
    question:
    Allied—DDT
    Syngenta, Zeneca AG, ICI Americas (all formerly doing business as
    Geigy)—DDT
    Maxus (formerly doing business as Diamond Alkali)—DDT
    Dupont—DDT
    Lebanon, as distributor for Montrose Chemical—DDT
    Montrose Chemical—DDT
    Pharmacia Corporation (formerly doing business as Monsanto)—DDT
    Velsicol—DDT
    Shell—Dieldrin
    PPG—BHC
    Hercules—Toxaphene
    On September 12, 2008, the trial court denied the defendants’ motions to compel
    7
    Garza’s case against 14 defendants was set for trial on October 20, 2008. On March 20, 2008, the
    trial setting was vacated at the plaintiffs’ request. Trial on Garza’s claim s was later reset to June 15, 2009.
    9
    as to Garza and granted Garza’s motion for trial setting. By a scheduling order entered on
    October 6, 2008, the court set Garza’s claims for trial on June 15, 2009.
    In their April 16, 2008 petition for writ of mandamus, the defendants challenge the
    trial court’s October 10, 2007 ruling in trial court cause number C-4885-99-F denying their
    motions for summary judgment and their fourth motion to compel an adequate answer to
    the Able-Supply interrogatory.8 The defendants also assert that the trial court abused its
    discretion by failing to rule on their motion to compel answers to the Borg-Warner
    interrogatory.
    Defendants’ November 25, 2008 petition, addressing Garza’s severed claims in trial
    court cause number C-4885-99-F(10), asks that we compel the trial court to (1) vacate its
    December 11, 2007 order severing Garza’s claims, (2) vacate its October 6, 2008 order
    denying defendants’ motions to compel and setting Garza’s claims for trial, and (3) grant
    defendant Aventis’s no-evidence motion for summary judgment.
    II. STANDARD OF REVIEW
    Mandamus will issue to correct a clear abuse of discretion for which the remedy by
    appeal is inadequate. In re Prudential Ins. Co. of Am., 
    148 S.W.3d 124
    , 135-36 (Tex.
    2004). A trial court abuses its discretion when it acts in an unreasonable or arbitrary
    manner or, stated differently, when it acts without reference to guiding rules and principles.
    See, e.g., Beaumont Bank, N.A. v. Buller, 
    806 S.W.2d 223
    , 226 (Tex. 1991). Additionally,
    an abuse of discretion occurs when the trial court clearly fails to analyze or apply the law
    correctly. Walker v. Packer, 
    827 S.W.2d 833
    , 840 (Tex. 1992).
    An appellate remedy is “adequate” when the benefits to mandamus review are
    outweighed by the detriments. In re Prudential Ins. Co. of 
    Am., 148 S.W.3d at 136
    . When
    the benefits outweigh the detriments, appellate courts must consider whether the appellate
    remedy is adequate.           
    Id. Nevertheless, in
    this context, “‘adequate’ . . . has no
    comprehensive definition; it is simply a proxy for the careful balance of jurisprudential
    8
    On February 6, 2008, defendant Maxus withdrew its m otion for sum m ary judgm ent.
    10
    considerations that determine when appellate courts will use original mandamus
    proceedings to review the actions of lower courts.” 
    Id. Whether an
    appellate remedy is
    “adequate” so as to preclude mandamus review depends heavily on the circumstances
    presented and is better guided by general principles than by simple rules. 
    Id. at 137.
    III. MOTIONS TO COMPEL
    We first address the defendants’ request that we order the trial court to grant their
    fourth motion to compel answers to the Able Supply interrogatory, filed on July 17, 2007,
    and their motion to compel answers to the so-called Borg-Warner interrogatory, filed on
    September 17, 2007.
    A.     Able Supply Interrogatory
    In Able Supply, the Texas Supreme Court clarified the burden which plaintiffs
    asserting immature mass-tort claims must meet at the discovery stage of 
    litigation. 898 S.W.2d at 771
    . “Requiring the plaintiffs to answer an interrogatory linking each plaintiff’s
    injuries with a particular product will simplify the case, streamline costs to both plaintiffs
    and defendants, conserve judicial resources, and aid the trial court in preparing a plan for
    the trial of these cases.” 
    Id. The defendants
    claim that the answers provided by both
    Garza and the non-trial plaintiffs are insufficient to satisfy this standard.
    In 2007, we held that mass-tort plaintiffs’ responses to Able Supply in a similar case
    were inadequate and that mandamus relief was appropriate to preclude the trial court from
    setting a plaintiff’s case for trial in the absence of an adequate such response. In re Van
    Waters & Rogers, Inc. (Van Waters III), No. 13-06-00153-CV, 2007 Tex. App. LEXIS 1883,
    at *13-18 (Tex. App.–Corpus Christi Mar. 6, 2007, orig. proceeding) (per curiam) (mem.
    op.). The plaintiffs in Van Waters III “either answered that (1) no health care provider has
    made the required connection between injury and exposure to the defendant’s products,
    or (2) have answered that a named health care provider has attributed the possibility of
    injury to chemicals generally, without specifying a particular product or products.” 
    Id. at *17.
    11
    Here, Dr. Wolfson’s report, unlike the plaintiffs’ response in Van Waters III, does
    attribute the possibility of each plaintiffs’ injury to specific chemicals. However, the report
    does not provide the defendant-specific causal link required under Able Supply. Dr.
    Wolfson’s affidavit and chart comprise what is essentially a compendium of epidemiological
    studies linking the plaintiffs’ symptoms with chemicals that could have caused them. Such
    studies cannot, by themselves, establish the actual cause of an individual’s injury or
    condition.    Merrill-Dow Pharms. v. Havner, 
    953 S.W.2d 706
    , 715 (Tex. 1997)
    (“epidemiological studies cannot establish the actual cause of an individual’s injury or
    condition”). That is because “[e]vidence that a chemical can cause a disease is no
    evidence that it probably caused the plaintiff’s disease.” In re 
    Allied, 227 S.W.3d at 656
    (citing 
    Havner, 953 S.W.2d at 714-21
    ) (emphasis in original). Indeed, Dr. Wolfson
    expressly stipulates that his opinions “are limited to . . . whether a pesticide is capable of
    causing a particular disease, condition or injury . . . and not . . .whether a pesticide, in fact,
    caused a plaintiff's disease, condition or injury” (emphasis added). Additionally, the non-
    trial plaintiffs’ responses do not link specific chemicals to specific defendants; this deprives
    the defendants of the ability to pinpoint which claims they may reasonably need to defend
    against and harms their ability to prepare a viable defense. See 
    id. at 658.
    A comparison with Garza’s responses is instructive. In her first supplemental
    response, Garza provided the identities of medical experts who have attributed her alleged
    injuries to exposure to specific products: “Guadalupe Garza supplements this response
    to state that Dr. Frank Gardner and Dr. William Sawyer have attributed her exposure(s) to
    toxaphene, dieldrin, DDT and BHC to the Non-Hodgkin’s Lymphoma.” Moreover, in her
    second supplemental response, Garza provided the report by engineer Kaltofen
    establishing that the allegedly injury-causing chemicals were produced by specific
    defendants to the Hayes-Sammons plant during the time period in question.
    The defendants claim that Garza has still not provided a sufficient Able Supply
    response because (1) the reports of Drs. Gardner and Sawyer do not link the allegedly
    12
    injury-causing chemicals with specific defendants, and (2) Kaltofen’s report does not
    provide “a medical determination that an illness has been caused by [a particular]
    defendant’s product.” See Able 
    Supply, 898 S.W.2d at 770
    . While it is true that the
    individual reports themselves may be insufficient, we conclude that when considering the
    reports together, Garza has provided an adequate response to the Able Supply
    interrogatory. That is because she has properly alleged the causal link between a specific
    product or products, produced by specific defendant or defendants, with her specific
    injuries. The reports of Drs. Gardner and Sawyer are sufficient to alert the defendants as
    to “whether there has been a medical determination that an illness has been caused by
    that defendant’s product,” see 
    id., and Kaltofen’s
    report links each defendant to specific
    products provided to the Hayes-Sammons plant. The responses together give each
    defendant notice as to which of their chemicals, if any, are alleged to have caused Garza’s
    injury; it thereby allows each defendant to be able to mount a defense and develop the
    merits of the case. The remaining non-trial plaintiffs must be held to this standard.
    We conclude that the non-trial plaintiffs’ responses to Able Supply are insufficient
    to establish causation, or to give the defendants an opportunity to prepare a viable
    defense. See In re Allied Chem. 
    Corp., 227 S.W.3d at 658
    . Accordingly, the trial court
    abused its discretion by failing to grant defendants’ fourth motion to compel adequate Able
    Supply responses from the non-trial plaintiffs.
    B.     “Borg-Warner Interrogatory”
    Defendants additionally claim that the trial court abused its discretion by failing to
    rule on their motion to compel answers to the so-called Borg-Warner interrogatory. The
    non-trial plaintiffs have not, as of yet, responded to the interrogatory; however, at the trial
    court’s hearing on October 10, 2007, they conceded that they are required to do so.
    The Borg-Warner court noted the following standard for expert opinions in an
    asbestos exposure case:
    An opinion on causation should be premised on three preliminary
    assessments. First, an expert should analyze whether the disease at issue
    13
    can be related to chemical exposure by a biologically plausible theory.
    Second, the expert should examine if the plaintiff was exposed to the
    chemical in a manner that can lead to absorption into the body. Third, the
    expert should offer an opinion as to whether the dose to which the plaintiff
    was exposed is sufficient to cause the 
    disease. 232 S.W.3d at 771
    (citing BERNARD D. GOLDSTEIN & MARY SUE HENIFIN , Reference Guide
    on Toxicology, in FEDERAL JUDICIAL CENTER , REFERENCE MANUAL ON SCIENTIFIC EVIDENCE
    401, 403 (2d ed. 2000)). The court further held that, in the context of asbestos litigation,
    “substantial-factor causation, which separates the speculative from the probable, need not
    be reduced to mathematical precision.                  Defendant-specific evidence relating to the
    approximate dose to which the plaintiff was exposed, coupled with evidence that the dose
    was a substantial factor in causing the asbestos-related disease, will suffice.” 
    Id. at 773.
    Although the mass tort considered here is immature, unlike asbestos litigation, we believe
    that the same standard is applicable in this context. The three “preliminary assessments,”
    made defendant-specific and including a dosage approximation, would suffice to put the
    defendants on notice as to the claims against which they may reasonably need to defend,
    and would allow them to prepare a viable defense. See In re 
    Allied, 227 S.W.3d at 658
    .
    Dr. Wolfson’s report, which was the most extensive interrogatory response provided
    by the non-trial plaintiffs, is not adequate for this purpose. The report, with its attached
    references, provides the first “preliminary assessment” in that it establishes the scientific
    possibility that certain chemicals provided by certain specific defendants caused the
    injuries complained of by plaintiffs.               It does not, however, provide the remaining
    assessments because it did not set forth an opinion as to: (1) whether it was possible for
    each individual plaintiff to have absorbed the chemicals in an amount sufficient to have
    caused the injury; or (2) whether the specific defendants’ chemicals did, in fact, cause the
    plaintiffs’ injuries.9     Accordingly, Dr. Wolfson’s affidavit and chart do not constitute
    adequate answers to the Borg-Warner interrogatory. The trial court therefore abused its
    9
    The1,848-page chart attached to Dr. W olfson’s affidavit sim ilarly fails to adequately answer the Borg-
    W arner interrogatory, because (1) it does not purport to m ake allegations as to specific causation, and (2) it
    is not defendant-specific.
    14
    discretion in failing to grant defendants’ motion to compel such answers from the non-trial
    plaintiffs.
    However, Garza’s Borg-Warner response provided detailed calculations as to the
    approximate doses of each chemical she was exposed to during the time period in
    question. Kaltofen’s report, which relied on “historical pesticide soil data” to indicate the
    precise dosage of each chemical Garza was likely exposed to at her childhood home,
    concluded as follows:
    I am certain, to within a reasonable degree of toxicological certainty that Ms.
    Garza’s chronic exposures to DDT, dieldrin, BHCs, and toxaphene released
    from Hayes-Sammons significantly contributed to the onset of her NHL. My
    review of her historical medical records, direct interview, and inspection of
    her 1016 Nicholson Street home failed to provide any other significant
    occupational or environmental exposures contributing to the onset of her
    NHL.
    Defendants contend that this response is inadequate because it is not defendant-
    specific; we disagree. Kaltofen’s report also contained a list, based on documentary
    evidence, identifying which specific manufacturers supplied the named chemicals to the
    Hayes-Sammons facility during the time period in question. Kaltofen concluded that
    defendants Allied, Syngenta, Zeneca AG, ICI Americas, Maxus, DuPont, Montrose
    Chemical, Pharmacia and Velsicol provided DDT; defendant Shell Chemical provided
    Dieldrin; defendant PPG Industries provided BHC; and defendant Hercules Inc. provided
    Toxaphene to the Hayes-Sammons plant during the time period in question.                  This
    conclusion, taken in combination with Garza’s supplemental response providing dosage
    approximations for DDT, Dieldrin, BHC, and Toxaphene, provided the three defendant-
    specific “preliminary assessments” as required under Borg-Warner. 
    See 232 S.W.3d at 771
    , 773. Accordingly, the trial court did not abuse its discretion in denying defendants’
    motion to compel a new Borg-Warner answer from Garza. Because Garza’s Able Supply
    and Borg-Warner responses were adequate, the trial court did not abuse its discretion by
    15
    severing her claims and setting them for trial.10
    The responses to the Borg-Warner interrogatory which will be provided by each of
    the non-trial plaintiffs must similarly be defendant-specific and show: (1) that the plaintiff’s
    complained-of injuries can be related to chemical exposure by a biologically plausible
    theory; (2) that the plaintiff was exposed to the chemical in a manner that can lead to
    absorption into the body; and (3) that the dose to which the plaintiff was exposed is
    sufficient to cause the complained-of injury. See 
    id. C. Adequate
    Appellate Remedy
    Having held that the trial court abused its discretion in failing to require the non-trial
    plaintiffs to adequately answer the Able Supply and Borg-Warner interrogatories, we now
    must consider whether defendants have an adequate appellate remedy in order to
    determine whether they are entitled to mandamus relief. See In re Prudential Ins. Co. of
    
    Am., 148 S.W.3d at 135-36
    .
    A party does not have an adequate remedy by appeal when that party’s ability to
    present a viable claim or defense is severely compromised or vitiated by the erroneous
    discovery ruling to the extent that it is effectively denied the ability to develop the merits of
    its case. See 
    Walker, 827 S.W.2d at 843
    . Plaintiffs have proposed answering the Able
    Supply and Borg-Warner interrogatories on a rolling basis, in groups of ten every 45 days.
    10
    Defendants claim that the suprem e court’s opinion in In re Allied Chem. Corp, 227 S.W .3d 652, 659
    (Tex. 2007) (orig. proceeding), requires that all plaintiffs file adequate Able Supply responses prior to any
    plaintiff’s claim s being set for trial, pointing to Justice Brister’s statem ent at the conclusion of the opinion that
    “we direct the trial court to vacate its order setting any of the plaintiffs' claim s for trial until the defendants have
    a reasonable opportunity to prepare for trial after learning who will connect their products to plaintiffs’ injuries.”
    
    Id. It is
    clear to this Court, however, that the statem ent m erely m eans that each individual plaintiff’s claim s
    m ay not be set for trial until that individual plaintiff has provided sufficient inform ation linking defendants’
    products to his or her injuries. The alternative interpretation advocated by defendants im plies that the
    suprem e court intended to foreclose trial against any plaintiff unless and until the defendants have a
    “reasonable opportunity to prepare for trial” against all of the hundreds of plaintiffs, a conclusion that we
    cannot countenance.
    M oreover, we do not believe that the suprem e court intended to abrogate or lim it the trial court’s
    discretion to sever a claim or to order a separate trial of any claim in furtherance of convenience. See T EX .
    R. C IV . P. 41 (“Any claim against a party m ay be severed and proceeded with separately.”), 174(b) (“The court
    in furtherance of convenience or to avoid prejudice m ay order a separate trial of any claim , cross-claim ,
    counterclaim , or third-party claim , or of any separate issue or of any num ber of claim s, cross-claim s,
    counterclaim s, third-party claim s, or issues.”).
    16
    At that rate, according to defendants, it would take over 23 years for the more than 1,800
    remaining plaintiffs to answer. Defendants ask that we require the trial court to compel
    answers “immediately” and raise the specter that, without such an order, 23 years will
    elapse without an adequate response.
    Although such a protracted period of litigation is certainly onerous to all parties, the
    nature of an immature mass tort is such that neat and expeditious conclusion to all
    litigation by all plaintiffs is next to impossible. Furthermore, it is not our province to impose
    a strict time-limited discovery mandate analogous to the statutory expert report
    requirements imposed upon medical malpractice claimants and asbestos or silica
    claimants. See TEX . CIV. PRAC . & REM . CODE ANN . §§ 74.351(a), 90.006(a) (Vernon Supp.
    2008). Defendants are simply not entitled to “immediate” responses to questions for which
    answers may take many years to develop.
    Nevertheless, the trial court may not abate meaningful discovery with respect to any
    of the plaintiff’s claims. See In re Van Waters & Rogers, Inc. (Van Waters I), 
    62 S.W.3d 197
    , 201 (Tex. 2001) (orig. proceeding). That is, plaintiffs are not absolved of the
    responsibility to timely provide adequate interrogatory responses merely because their
    ranks are numerous. We are concerned that the trial court has failed to set any temporal
    guidelines for the production of discovery, particularly in a case involving such a wide array
    of claims and claimants. Regardless of the procedural obstacles presented by a case
    involving thousands of parties, the defendants are entitled to full, fair discovery within a
    reasonable period of time. See Able 
    Supply, 898 S.W.2d at 773
    .
    We note that the rules of civil procedure require that “a party must make a complete
    response, based on all information reasonably available to the responding party or its
    attorney at the time the response is made.” TEX . R. CIV. P. 193.1; see In re Allied Chem.
    
    Co., 227 S.W.3d at 657
    . Thus, the plaintiffs are not at liberty to withhold any information
    from the defendants if such information is reasonably available. However, to the extent
    that the trial court’s failure to set appropriate temporal guidelines for discovery in this
    17
    matter constitutes an abatement of discovery with respect to the non-trial plaintiffs, it is in
    contravention of the supreme court’s rulings in Van Waters 
    I, 62 S.W.3d at 201
    , and In re
    Allied Chemical 
    Co., 227 S.W.3d at 657
    .             Such an abatement would deprive the
    defendants of an adequate appellate remedy because it would vitiate their ability to
    develop the merits of the case. See 
    Walker, 827 S.W.2d at 843
    ; see also Van Waters III,
    2007 Tex. App. LEXIS 1883, at *15-16.
    We therefore conditionally grant in part the writ requested in defendants’ April 16,
    2008 petition and order the trial court to require that all non-trial plaintiffs produce adequate
    answers to the Able Supply and Borg-Warner interrogatories within a reasonable time
    period as determined by the trial court.
    IV. MOTIONS FOR SUMMARY JUDGMENT
    We next address defendants’ request that we compel the trial court to grant their
    motions for summary judgment first filed on September 9, 2004.
    A.     Non-Trial Plaintiffs
    After adequate time for discovery, a party without presenting summary judgment
    evidence may move for summary judgment on the ground that there is no evidence of one
    or more essential elements of a claim or defense on which an adverse party would have
    the burden of proof at trial. TEX . R. CIV. P. 166a(i).
    Defendants, citing In re 
    Prudential, 148 S.W.3d at 135-36
    , contend that they have
    no adequate appellate remedy available to them with respect to the trial court’s denial of
    their summary judgment motions. However, the defendants do not direct us to any
    authority indicating that mandamus relief is appropriate to remedy, specifically, a trial
    court’s denial of a summary judgment motion.
    Without determining whether mandamus is appropriate in this context, we note that
    a trial court errs in granting a no-evidence motion for summary judgment if “adequate time
    for discovery” has not elapsed. See TEX . R. CIV. P. 166a(i); Brewer & Pritchard, P.C. v.
    Johnson, 
    167 S.W.3d 460
    , 469 (Tex. App.–Houston [14th Dist.] 2005, pet. denied); Caso-
    18
    Bercht v. Striker Indus., 
    147 S.W.3d 460
    , 463 (Tex. App.–Corpus Christi 2004, no pet.).
    With respect to the claims of the non-trial plaintiffs, we agree with the defendants that
    these plaintiffs have not yet complied with the requirements of Able Supply and Borg-
    Warner and that they must be required to so comply within a reasonable period of time.
    See Able Supply 
    Co., 898 S.W.2d at 773
    . However, for the same reason that we will not
    impose strict time limits such as those the legislature has imposed on medical malpractice
    plaintiffs or asbestos and silica claimants, we cannot say that a reasonable time—or an
    “adequate time for discovery”—has yet elapsed in this case with respect to the non-trial
    plaintiffs. Accordingly, the trial court’s denial of the defendants’ motions for summary
    judgment was not an abuse of discretion for which no adequate appellate remedy is
    available. We deny the defendants’ request to compel the trial court to grant their
    summary judgment motions as to the non-trial plaintiffs.
    B.     Garza’s Claims
    Insofar as we have determined Garza’s Able Supply and Borg-Warner responses
    to be adequate, the defendants are not entitled to summary judgment on that particular
    plaintiff’s claims.
    With respect to defendant Aventis’s motion for summary judgment, however, the
    record reflects that the trial court has not yet ruled on the motion but, rather, took the
    matter under advisement as of December 11, 2007. Aventis asks that we compel the trial
    court to grant its motion, noting that Aventis, unlike the other defendants that moved for
    summary judgment, was not listed by Kaltofen as having provided any of the named
    chemicals to the Hayes-Sammons plant during the time in question. We agree that
    Kaltofen’s report is critical to Garza’s case as to each defendant because it provides, in
    combination with the report detailing the estimated dosage of each chemical that Garza
    was exposed to, the essential defendant-specific causal link between chemicals produced
    and Garza’s injuries. Aventis’s absence from Kaltofen’s list indicates that Garza has not
    yet met her pre-trial burden under Borg-Warner with respect to that defendant. Moreover,
    19
    because trial in that cause is scheduled for June 15, 2009, Garza’s failure to date to meet
    that burden jeopardizes her claims against Aventis. See In re 
    Allied, 227 S.W.3d at 655
    (a trial judge cannot postpone responses to basic discovery until shortly before trial), 658
    (allowing discovery to continue to thirty days before trial amounts to a denial of discovery
    going to the very heart of the case).
    Because the trial court has not yet ruled on Aventis’s motion for summary judgment,
    we will not direct a particular judgment. However, a trial court’s failure to rule on a matter
    may be deemed an abuse of discretion subject to mandamus relief if the petitioner shows
    that the trial court: (1) had a legal duty to rule; (2) was asked to rule; and (3) failed or
    refused to do so. In re Dimas, 
    88 S.W.3d 349
    , 351 (Tex. App.–San Antonio 2002, orig.
    proceeding); In re Chavez, 
    62 S.W.3d 225
    , 228 (Tex. App.–Amarillo 2001, orig.
    proceeding); Barnes v. State, 
    832 S.W.2d 424
    , 426 (Tex. App.–Houston [1st Dist.] 1992,
    orig. proceeding). A trial court has a reasonable time to perform the ministerial duty of
    considering and ruling on a matter properly filed and before the court. In re 
    Chavez, 62 S.W.3d at 228
    ; 
    Barnes, 832 S.W.2d at 426
    . Whether the judge has acted within a
    “reasonable” period of time depends on the circumstances of the case. In re 
    Chavez, 62 S.W.3d at 228
    (“No bright-line demarcates the boundaries of a reasonable time period.”).
    Here, Aventis filed its motion for summary judgment on March 3, 2005; the trial court
    heard evidence thereon and took the matter under advisement on December 11, 2007.
    We believe that the trial court has had ample time to review the merits of the motion as it
    relates to Garza’s claims, especially considering the impending trial date of June 15, 2009.
    We conclude that the trial court abused its discretion by failing to rule on Aventis’s no-
    evidence motion for summary judgment on Garza’s claims, and we direct the trial court to
    so rule.
    VI. CONCLUSION
    We conditionally grant the writ of mandamus requested in appellate cause number
    13-08-00206-CV in part, and direct the trial court to grant defendants’ fourth motion to
    20
    compel in part by requiring all plaintiffs in trial court cause number C-4885-99-F to provide
    adequate answers to the Able Supply and Borg-Warner interrogatories within a reasonable
    time period as determined by the trial court. Further, we conditionally grant the writ of
    mandamus requested in appellate cause number 13-08-00678-CV in part, and direct the
    trial court to rule on defendant Aventis’s motion for summary judgment in trial court cause
    number C-4885-99-F(10).
    The writs will issue only if the trial court fails to comply. The petitions for writ of
    mandamus filed in appellate cause numbers 13-08-00206-CV and 13-08-00678-CV are
    denied in all other respects.
