    PER CURIAM
    This appeal arises from a dispute over the source of environmental
    contamination caused by the discharge of tetrachloroethylene (also known as
    perchloroethylene or PCE) onto property owned by plaintiff Clarke Brothers,
    Inc. (CBI). CBI operated a gasoline station and an automobile repair facility on
    the property and discovered the PCE contamination while remediating
    chemicals that had leaked from its underground storage tanks.
    A-1793-18
    2
    I.
    In 2008, CBI and its receiver, Alan E. Meyer (collectively, plaintiffs),
    filed a complaint against the owners of an adjacent three-unit shopping center 1
    and the owners and operators of the dry-cleaning business that leased one of the
    units.2   The complaint alleged that the dry-cleaning operations caused the
    discharge of PCE, which migrated downhill onto the CBI property, and that the
    PCE contamination prevented plaintiffs from selling their property and
    decreased its market value.    Plaintiffs sought relief under the New Jersey
    Environmental Rights Act (ERA), N.J.S.A. 2A:35A-1 to -14, the New Jersey
    Spill Compensation and Control Act (Spill Act), N.J.S.A. 58:10-23.11 to -23.24,
    and various common law causes of action.3
    1
    Defendants Michael and James Constantinou purchased the shopping center
    property in 1993 and constructed a new building in 1995. The following year
    the Constantinous began leasing a portion of the shopping center property to a
    dry-cleaning business – Atlantic Cleaners.
    2
    Atlantic Cleaners was purchased by defendant Silver Hanger of Manasquan,
    Inc. in 1996. Silver Hanger was owned by defendant John O'Connor and Robert
    Kowalski. In 2007, Silver Hanger sold its assets to defendant Han Lim and S.J.
    Prodigy. The business continued to operate as Atlantic Cleaners throughout this
    litigation.
    3
    In 2010, the Constantinous transferred title to the shopping center property to
    defendant Manasquan Plaza, Inc. Each brother owned fifty percent of the shares
    of Manasquan Plaza.
    A-1793-18

    A.
    In November 2011, Silver Hanger and O'Connor filed a motion to refer
    plaintiffs' action to the New Jersey Department of Environment Protection
    (DEP) pursuant to N.J.S.A. 2A:35A-8, "the statutory provision of the ERA that
    directs a court to remit parties to administrative proceedings that are 'required
    or available to determine the legality of the defendant's conduct.'" Meyer v.
    Constantinou, No. A-4163-11 (App. Div. Nov. 15, 2013) (slip op. at 8).
    On March 12, 2012, the trial court signed an order dismissing the
    complaint without prejudice and referring the environmental claims to DEP
    which was "actively enforcing the environmental laws" with regard to the CBI
    and Constantinou properties.
    CBI appealed from the March 2012 order. We affirmed, holding that
    plaintiffs had the ability "to cooperate with DEP in determining the extent of the
    contamination and the scope of the cleanup" and that after accomplishing those
    objectives, they could move to reinstate the complaint. Id. at 16.
    During the pendency of the appeal, the court entered a final judgment of
    foreclosure against the CBI property. A sheriff's sale took place in January 2019
    and the deed was transferred to the buyer on March 13, 2019.
    A-1793-18
    4
    After this court affirmed the order of referral to DEP, the Supreme Court
    released its decision in Magic Petroleum Corp. v. Exxon Mobil Corp., 
    218 N.J. 390
    , 409-10 (2014), which held that under the Spill Act, property owners could
    file contribution claims in New Jersey Superior Court and the court could
    allocate liability before final resolution of a site remediation plan.
    Therefore, on August 6, 2014, plaintiffs filed a motion for the trial court
    to reconsider its decision to refer the matter to DEP. The motion was granted
    and the matter returned to the trial court.
    B.
    Silver Hanger and O'Connor filed a motion for summary judgment
    seeking, among other things, to dismiss the ERA claim on the basis that
    plaintiffs failed to establish a continuous or intermittent violation. In their reply
    papers, these defendants asserted that plaintiffs' expert opinion was net opinion
    and should be barred. The court denied the motion and found the issue of net
    opinion had not been properly raised. A subsequent motion for reconsideration
    was also denied. Plaintiffs and Lim reached a settlement agreement in May 2016
    and the claims against those defendants were dismissed.
    Plaintiffs were permitted to proceed on their claim for consequential
    damages as they produced two contracts for the sale of the property which they
    A-1793-18
    5
    alleged they were unable to consummate because of their financial condition and
    inability to undertake the necessary remediation to sell the property.
    II.
    The case proceeded to a bench trial before Judge Jamie S. Perri over
    seventeen days between October 30, 2017 to December 14, 2017. On the first
    day of trial, defendants Silver Hanger and O'Connor requested a N.J.R.E. 104
    hearing for the court to determine whether plaintiffs' expert – Christopher
    Neuffer – had sufficient qualifications to support his testimony. Counsel also
    argued that Neuffer's expert report was net opinion.
    Because the case was proceeding as a bench trial, Judge Perri declined to
    conduct a Rule 104 hearing. She reasoned that because there was no jury, she
    could hear the expert's testimony and subsequently determine the net opinion
    issue.
    After plaintiffs completed their presentation of evidence, defendants
    moved for dismissal of all claims under Rule 4:37-2(b). The court granted the
    motion only for dismissal of the claims asserted against O'Connor for personal
    liability.
    On October 29, 2018, the court issued a comprehensive written opinion
    finding plaintiffs had not proven their claims and entering judgment in favor of
    A-1793-18
    6
    defendants. Judge Perri determined that plaintiffs' expert, Neuffer, had provided
    only a net opinion which could not support their claims. She stated further that,
    even if she had considered his opinion, Neuffer's testimony was not sufficiently
    credible to support a finding of proximate cause. The court also found plaintiffs
    could not pursue a cause of action under the ERA under the presented
    circumstances. The court memorialized its decision in a November 13, 2018
    order.
    III.
    On appeal, plaintiffs contend the trial court erred in: (1) finding Neuffer
    offered an inadmissible net opinion; (2) dismissing their claims under the ERA;
    and (3) dismissing the liability claims against O'Connor personally.
    To provide context for our decision, we provide the following facts
    elicited at trial.
    CBI Property
    Brothers Peter and John Clarke formed CBI in 1976 and, shortly
    thereafter, CBI purchased an existing gas station and automotive repair shop.
    They operated the business as a Gulf Service station. A one-story, four-bay
    cement block building was located in the central portion of the CBI property.
    Storage sheds and trailers were located along the property's northeastern border
    A-1793-18
    7
    adjacent to the shopping center owned by the Constantinous. The diesel fuel
    dispenser was located on the southeast corner of the property, and the gasoline
    pump island was located on the east side of the building.
    The property also contained five underground storage tanks (USTs),
    including three gasoline tanks, one diesel tank, and one waste oil tank. The
    gasoline and diesel tanks were located on the south side of the service building;
    two tanks held 8000 gallons of gasoline, one tank held 6000 gallons of gasoline,
    and one tank held 3000 gallons of diesel fuel. Gulf Oil replaced the gasoline
    tanks in the late 1980s or early 1990s.
    On the north side of the building, an underground tank held 250-275
    gallons of waste oil. This tank was present when the Clarke brothers purchased
    the property and was not replaced. Peter testified that he and his brother did not
    use that tank in their business.4 Instead, they used above-ground waste oil tanks.
    Peter said he and his brother never used PCE in the business . To clean
    tools, they used a spray can of cleaner "that anybody can buy." They would
    spray the brakes "to keep the dust down" and blow them dry. He did not know
    4
    Plaintiffs took Peter's de bene esse deposition in 2009. He died prior to the
    trial. The videotaped deposition was played in court.
    A-1793-18
    8
    the name of the spray can products or their chemical composition. He stated
    that no other maintenance work required the use of the spray cans.
    In 2000, CBI closed the gas station due to the cost of equipment upgrades.
    It retained Meridian Environmental Services (Meridian) to remove the four
    gasoline tanks and the piping connecting the tanks to the pumps. Peter testified
    that they retained an environmental company because they had "very generous
    offers" to buy the property, but "no one would buy it until everything was
    removed."
    During   his   deposition,   Peter   acknowledged     having   "difficulty
    remembering." He did not recall the name of the company retained by CBI or
    the date it removed the tanks. He also did not recall any assessment by DEP of
    penalties against CBI, a letter from the municipality warning against his
    intention to spread contaminated soil over his property, or the date when the
    contaminated soil was removed.
    In August 2000, Meridian removed the pump island, three gasoline USTs,
    and the diesel fuel UST; the inspection of each tank did not reveal any holes.
    In removing the waste oil tank, located adjacent to the dry-cleaning
    business, Meridian found "pea-sized holes" at one end of the tank. Therefore,
    the company collected a soil sample from that area of the tank. An analysis of
    A-1793-18
    9
    the sample detected total petroleum hydrocarbons (TPH), including heating and
    diesel oil. Based on the presence of TPH, the sample was further analyzed for
    volatile organics that were associated with waste oils or petroleum products.
    The scan detected xylene slightly in excess of DEP standards.
    Meridian lined the waste oil tank excavation with plastic before filling it
    with clean soils and called the DEP hotline to report a discharge of hazardous
    substances. Because the waste oil tank was located between CBI's service
    building and the Constantinous' adjacent property, no further excavations in this
    area were done. Meridian backfilled the excavations around the USTs and
    removed a truckload or approximately twenty-five tons of suspected
    contaminated soil. It stockpiled a small amount of contaminated soil on site.
    In September 2004, during a site visit by the municipality's Director of
    Code Enforcement, Peter stated he intended to spread the stockpiled soil over
    the property. In a letter dated October 5, 2004, the director "strongly suggested"
    that Peter refrain from disturbing "the pile of soil" without getting permission
    from the State. Nevertheless, CBI used the stockpiled soil to grade off the
    surface of the former tank excavation area after the soil had settled.
    A-1793-18
    10
    As stated, the brothers had decided to sell the property. CBI was in
    financial trouble. Peter testified there were substantial tax liens on the business
    and property for some time, even prior to John's death in December 2005.
    CBI executed a contract of sale with a developer to buy the property for
    $600,000 in March 2005. The contract was contingent in part on CBI obtaining
    a no further action (NFA) letter from DEP, indicating the property was clear of
    any contaminants.
    When the potential buyer retained an engineering company to perform a
    survey of the property, the company detected two areas of chemical
    contamination on the north side of the property between the service building and
    adjacent shopping center, and one area of oil contamination in the northwest
    corner. Although the buyer was willing to go forward with the sale, CBI was
    unable to obtain an NFA letter. The buyer cancelled the contract in August
    2007.
    Peter's former wife testified during the trial that she recalled interest in
    the property but she was unsure if there were other offers. She and Peter testified
    that the cancellation of the executed contract and the inability to find a different
    buyer due to the PCE contamination had a financial impact on the business and
    on their personal finances. When Peter closed the auto repair shop in December
    A-1793-18
    11
    2006, his wife said there were federal and state tax liens on the property in
    addition to "many outstanding debts, not only to the IRS but to the -- vendors
    and to the [municipality], property taxes."
    In December 2006, the court appointed Meyer as fiscal agent to "marshal"
    CBI's books and records, and to pay expenses. In June 2007, at the request of
    John's widow, the court appointed Meyer as receiver for CBI to manage the sale
    of its property and determine its liabilities. At the time, CBI had no liquid assets
    or available funds.
    In March 2008, a second entity offered to purchase the CBI property for
    $700,000 "with numerous contingencies."            The buyer intended to build
    condominiums on the property. He stated that groundwater contamination was
    a "deal breaker" for him because it would significantly impact the property's
    value.
    During the course of negotiating the contract and the contingencies, Peter
    and the potential buyer learned from Neuffer that his investigation confirmed
    that PCE had contaminated the groundwater. The buyer terminated the contract.
    Meyer made no further effort to sell, rent, or lease the property after the two
    potential buyers withdrew their purchase offers. Because of the accrual of taxes
    A-1793-18
    12
    and penalties, the property ultimately went into foreclosure and was sold during
    the pendency of the litigation.
    Plaintiffs' claim against defendants was for the consequential damages
    they alleged were incurred as they were unable to consummate two contracts for
    the sale of their property because of their financial condition and inability to
    undertake the necessary remediation to sell the property.
    Atlantic Cleaners
    The shopping center owned and constructed by the Constantinous was
    located about twenty to twenty-five feet from the CBI service building. There
    was a fence along the northern border between the properties. Neuffer stated
    that beyond the rear door of the dry-cleaning business was a concrete sidewalk,
    then a two-foot area of soil up to the fence separating the Constantinou property
    from the Clarke property. The fence was on the northern property boundary of
    CBI adjacent to the soil excavation conducted for the former waste oil tank. The
    distance from the rear door to the Clarke Brothers property was approximately
    six feet.
    As stated, O'Connor and his partner, Kowalski, purchased the shares of
    Silver Hanger and took over a lease in the shopping center from the owner of a
    dry-cleaning corporation. They also purchased the dry-cleaning equipment from
    A-1793-18
    13
    the prior owner. In June 1997 they opened Atlantic Cleaners. The partners hired
    O'Connor's wife and son and Kowalski's wife to assist in the daily operations of
    the company.
    O'Connor had no prior experience operating a dry-cleaning facility.
    Before purchasing the business, he and Kowalski spent five days observing the
    operation of another dry cleaners. After the purchase, O'Connor's son and
    Kowalski's wife attended two or three weeks of training on the operation of dry -
    cleaning machinery. During the first two months of its operation, the prior
    owner provided two people to work at the dry cleaners and assist with the
    transition to make sure the operation was "running as planned."
    At first, O'Connor's son and Kowalski's wife were the only people who
    operated the dry-cleaning machine. However, after retiring from his principal
    job in 1998, O'Connor attended a three-week training course on the operation of
    dry-cleaning machinery conducted by the National Cleaners Association (NCA).
    Until 2000, O'Connor worked mostly on weekends. He operated the dry-
    cleaning machine alone or assisted his son. Kowalski's wife left the business in
    2000 and for the next year O'Connor worked there three to four days a week. In
    2001, he left to join a family-owned business, but returned to Atlantic Cleaners
    A-1793-18
    14
    in 2002 and worked there "three days on, three days off, a week on or a week
    off."
    Atlantic Cleaners used a Multimatic dry-cleaning machine which
    contained a closed-vent system with carbon absorbers to remove vapors from
    the system. Atlantic also purchased a containment tank from the manufacturer
    of the dry-cleaning machine. The ten-inch-high steel tank went under the
    machine and surrounded it on all sides, with two feet extending behind the motor
    pumps and button traps, and one foot in front, so any leaks of PCE would fall
    into it. The dry-cleaning machine was used three times a day for five days a
    week. Only O'Connor and his son, and Kowalski and his wife could operate the
    machine and remove and dispose of its waste.
    At the time of his purchase of the business, O'Connor was aware that the
    dry-cleaning machine used a chlorinated solvent, PCE. During the ten years that
    O'Connor owned and operated the business, Atlantic Cleaners used PCE.
    O'Connor described PCE as a carcinogen. He was aware of OSHA regulations
    and requirements regarding its handling and storage.
    O'Connor testified that the PCE used in the dry-cleaning machine
    discharged vapors. In 1999, Atlantic Cleaners purchased a halogen device to
    measure the volume of PCE in the air. By 2000 the employees were using the
    A-1793-18
    15
    halogen device every day. O'Connor said "there were times when we would
    detect a vapor leak, which would require a gasket to be changed. And that was
    the benefit of it."5 He usually operated the dry-cleaning machine in the morning
    to shield his employees and customers from exposure to the PCE vapor .
    O'Connor said that a vendor placed the PCE in the machine. Deliveries
    were made through the rear door of the business and the vendor would place a
    drum containing PCE into the "button trap," which would "move the chemical
    into the machine." The solvent was used in lieu of water and detergent to remove
    dirt and stains on clothes.
    The PCE and its waste by-products were removed daily from the machine.
    A spout with an open valve would drain the "wastewater" into a three -to-five-
    gallon plastic bucket that hung from the back of the machine. After the machine
    was shut down and the lint, waste bucket, and strainers were cleaned, the
    operator would carry the uncovered bucket over the waste containment tank and
    then pour the wastewater into an unlocked plastic receptacle, lock the receptacle,
    and put the bucket back on the machine for use the next day. O'Connor estimated
    they collected a quart of wastewater a day. He stated there was no floor drain
    near the machine.
    5
    Gaskets held the filters in place.
    A-1793-18
    16
    The Atlantic Cleaners employees also changed the spent filters that
    removed impurities from the solvent, and they removed sludge and lint from the
    machine. The filters, sludge, and lint collections contained traces of PCE. There
    were separate receptacles for wastewater, sludge, and lint which had lids and
    were kept a few feet behind the back of the machine, approximately twenty-five
    feet from the rear door of the business.
    Atlantic Cleaners used a licensed disposal company to remove the
    wastewater, sludge, and lint receptacles and replace them with new containers.
    On average, the company removed the wastewater container about once a month.
    If the bucket was close to full, O'Connor or another employee would ask the
    disposal company to remove it. He said the disposal company would place the
    locked receptacle on a dolly and remove it through the rear door. The lint and
    sludge receptacles were removed every two to three months.
    The dry-cleaning machine was serviced as needed by specialized
    individuals recommended by the manufacturer. O'Connor, his son, Kowalski,
    and his wife also performed service and maintenance on the machine. On every
    day of use, the operator felt around the machine for residue and visually looked
    under it "to see if anything was dripping." The operator also conducted daily
    inspections of the "pipe connections, fittings, couplings and valves," in areas
    A-1793-18
    17
    where PCE came through, as well as the pumps, filter gaskets, solvent tanks and
    containers, and the water separator. As stated, the operator also performed daily
    inspections using the halogen detector to determine whether there were any PCE
    leaks.
    O'Connor testified that his employees used "checklists from day one" to
    show the business complied with inspections and the handling of any PCE leaks.
    The business kept daily records and weekly condenser temperature and leak
    inspection logs recommended by DEP.
    According to O'Connor, PCE was ordered "as needed," with deliveries
    occurring every three to four months. Each delivery consisted of approximately
    19.2 gallons of PCE solution with approximately sixty-seven gallons delivered
    annually.
    O'Connor never witnessed or heard anyone report a spill of wastewater on
    the premises or a discharge to the environment. He specifically denied ever
    having a spill in the area outside the dry cleaner's back door.
    O'Connor was aware of self-contained leaks in the steel tank of the dry-
    cleaning machine. He stated:
    And I think I mentioned yesterday that we found many
    times with our hands that there would be a residue and
    you would change the gasket. We did have a leak or
    two, few leaks that we had over the course of the years.
    A-1793-18
    18
    It's a machine. That's why we put the container tank
    there.
    O'Connor was aware of approximately five to ten gasket leaks of PCE
    during his ownership and operation of Atlantic Cleaners. He performed two of
    the repairs himself. In one instance, he notified DEP, but it was not a "reportable
    incident" because the leak was contained in the tank and "did not hit the
    environment." He also recalled a leak of PCE into the motor pump, which he
    fixed by tightening a fitting. On the other occasions, Kowalski fixed the leaks
    by replacing gaskets.
    O'Connor explained that any leaks from the machine went into the steel
    containment tank, where rags would soak up the chemical. The operator then
    wrung out the rags in the button trap, placed them back into the machine and ran
    the cycle again. O'Connor said he learned this procedure during his training at
    the NCA. He further explained: "There's no drips into the containment tank, it
    means that it was just moisture starting to come, it was indicating that the gasket
    was starting to corrode and needed to be inspected." He also advised that
    government authorities inspected the dry-cleaning operations during his years
    of ownership, and the business was never cited for noncompliance with any laws
    or regulations. O'Connor testified he did not learn of any PCE contamination of
    A-1793-18
    19
    either the CBI property or the Constantinou property until after the sale of the
    dry-cleaning business.
    In May 2007, Silver Hanger sold the business to Prodigy, which was
    owned equally at the time by Lim and his mother. The sale included the dry-
    cleaning machine.
    Before buying the business, Lim received training for two weeks from
    Kowalski. Lim used PCE in the same dry-cleaning machine until July 2012,
    when he bought a new machine that used a non-hazardous cleaning substance.
    He replaced the machine because it was "old and wearing down." He denied
    any leaks of PCE while the old machine was in place. He was still operating
    Atlantic Cleaners at the time of trial.
    Michael Constantinou also testified at trial. He stated he was unaware of
    any spill of PCE within or outside of the dry-cleaning premises while Silver
    Hanger owned the operation. He did recall Lim telling him of an incident in
    2012 when PCE leaked from the machine onto the floor inside the dry-cleaning
    store. He also described a second incident in 2012 when the disposal company
    that removed the waste spilled some of it onto the sidewalk behind the dry
    cleaners. The Constantinous reported that spill to DEP, which investigated and
    tested the wastewater and had no concerns. According to Michael, DEP stated
    A-1793-18
    20
    there was no indication of any PCE in the spilled wastewater. Both of these
    events occurred after Atlantic Cleaners was sold to Lim and after the lawsuit
    was filed.
    Counsel also questioned O'Connor about the grade level of the
    Constantinou property as compared to the CBI property. He said that from 1997
    to May 2007 the Constantinou property was lower than the CBI property . He
    described that after rain storms the water flowed from the CBI property into the
    rear door of the dry cleaners.
    Michael Constantinou also recalled that "for the longest period of time"
    the CBI property was higher than the Constantinou property. However, after the
    Clarkes excavated some of the soil on their property, Michael stated the
    Constantinou property had a higher elevation by one or two inches.
    Remediation of the CBI Property
    In February 2005, DEP conducted a compliance evaluation and found
    violations related to the August 2000 removal of the USTs on the CBI property.
    It ordered CBI to submit a site investigation report detailing the prior removal
    of the storage tanks and a remedial investigation report.
    The following year, CBI retained Neuffer and his company, Envirotactics,
    Inc. – a consulting company that performed environmental investigation and
    A-1793-18
    21
    remediation work.       In March 2006, Envirotactics prepared a remedial
    investigation report regarding the removal of the five USTs by Meridian. As
    previously noted, Meridian had found surficial contamination, meaning it was
    limited to the upper two feet of soil, and attributed it to a spilling or overfilling
    of the tanks. Relying on Meridian's findings, Envirotactics determined that no
    additional investigation or remediation was required with the exception of the
    waste oil tank.    It proposed additional soil excavation, disposal, and post-
    excavation soil sampling in the waste oil tank area, along with disposal of soils
    "impacted by the gasoline tank overfill release."
    In following through with its proposal, Envirotactics conducted its first
    excavation in the area of the former waste oil tank to remove contaminated soils,
    and also performed post-excavation sampling. Envirotactics also re-excavated
    and removed approximately one foot of the contaminated soil which had been
    spread over the area of the former gasoline and diesel fuel oil tanks and
    stockpiled it with the soil removed from the area of the waste oil tank.
    The company also collected eight soil samples along CBI's property line
    with Manasquan Plaza. The purpose of the samples was to document that all the
    contaminated soil had been removed and that the vertical excavation was
    complete. One of the eight samples, taken at the western end of the excavation
    A-1793-18
    22
    (the farthest distance from the Constantinou property), detected the highest level
    of TPH and was sent to a laboratory to analyze for volatile organics. PCE was
    detected at a reported level of 120 ppm, which was above the DEP's most
    stringent cleanup criteria.
    Thereafter, Envirotactics conducted additional soil excavation along the
    northern end of the property adjacent to the fence along the property boundary
    and collected post-excavation samples. Testing of the samples revealed PCE.
    The company also removed approximately twenty tons of soil, which it
    stockpiled separately.
    In late March 2006, Envirotactics collected three additional soil samples
    to determine whether the PCE contamination was due to an off-site discharge.
    Two samples were collected about one foot from the fence; one sample was
    collected on CBI's property directly opposite the rear door of the dry cleaners
    and the other was collected approximately twenty feet to the east towards the
    area of the former waste oil tank. All three samples detected PCE, with the two
    samples near the property line indicating higher concentrations.
    On May 2, 2006, Envirotactics submitted a remedial action report
    addressing the February and March 2006 investigations.                  Although
    acknowledging soil sampling in the area of the waste oil tank detected PCE,
    A-1793-18
    23
    Neuffer stated "reportedly, chlorinated solvents were not utilized by Clarke
    Brothers." He noted that "additional soil sampling was performed along the
    property boundary in the general area of the former waste oil tank and in an area
    away from the waste oil tank. PCE contaminated soil was identified in higher
    concentrations than those previously detected in the area of the waste oil tank."
    Neuffer also reported that soils collected at the property line ten feet
    directly across from the rear door of the dry cleaners had "a distinct dry cleaning
    solvent (PCE) odor." He stated that "the surface drainage from the adjacent
    property containing the dry cleaning operation is towards the Clarke Brothers
    property." Therefore, he concluded, "it is apparent that the [PCE] has migrated
    onto the [CBI] site from the adjacent property that is operated as a dry cleaner."
    Neuffer requested DEP issue an NFA letter regarding the PCE on the CBI
    property.
    DEP responded by requesting Envirotactics conduct more sampling to
    establish that the PCE contamination on the CBI property was not associated
    with the former USTs.       In July 2006, Neuffer and Peter entered into a
    memorandum of agreement (MOA) with DEP, stating that an off-site source
    existed for the contamination detected on the CBI property and outlining certain
    environmental work to be performed.
    A-1793-18
    24
    In October 2006, Neuffer submitted a remedial investigation report to
    DEP for the PCE detected on the CBI property not associated with the USTs.
    The report addressed the excavations relating to the removal of the waste oil
    tank, and the test results of various samples. It noted that higher concentrations
    of PCE were detected along the northern boundary, that the soils near the dry
    cleaners had a distinct PCE smell, that CBI did not use chlorinated solvents in
    its auto repair services, and that the dry cleaners recently installed a new system .
    Envirotactics concluded: "Since soil sample results confirm that the PCE
    contamination has migrated onto the Clarke Brothers property from an offsite
    source, no further investigation or remediation is proposed. Clarke Brothers is
    not responsible for contamination originating from an offsite source."
    The same month, DEP issued an Administrative Order and Notice of Civil
    Administrative Penalty Assessment to plaintiffs of $26,000 for violations,
    including the failure to submit a site investigation report, to determine the
    classification of wastes, and to submit a remedial investigation report. DEP also
    cited CBI for failure to remove the contaminated soil. In February 2008, DEP
    and Meyer on behalf of CBI entered into a settlement agreement that addressed
    the violations and enforcement actions and imposed a reduced penalty of
    $13,000.
    A-1793-18
    25
    In the interim, in March 2007, Envirotactics submitted a remedial
    investigation report to obtain an NFA letter for the tank-removal investigation
    and remediation. The company conducted groundwater and soil investigations
    and concluded that no further investigation of groundwater was necessary and
    that the only outstanding issue was the disposal of the stockpiled soil . On July
    6, 2007, Envirotactics reported to DEP that the stockpiled soil was properly
    disposed of and requested an NFA letter with a covenant not to sue for the USTs
    removals.
    In June 2007, Neuffer collected three samples near the rear door of the dry
    cleaners. These samples detected PCE, with the highest level being next to the
    concrete sidewalk at the rear of the dry-cleaning operation. The concentrations
    exceeded DEP's most stringent cleanup criteria. Neuffer stated these levels far
    surpassed the highest concentration of PCE in any sample taken from the CBI
    property.
    In its remediation investigation report addendum dated August 2007,
    Envirotactics wrote that the additional soil sampling on the Constantinou
    property identified higher levels of PCE than previously detected at the property
    boundary. Therefore, Neuffer concluded again that the contamination on the
    CBI site came from Atlantic Cleaners. He supported his conclusion with the
    A-1793-18
    26
    same reasons he had previously presented in his May 2006 report: (1) CBI did
    not use chlorinated solvents; (2) PCE was a common chemical used in the dry-
    cleaning industry; (3) the rear door of the dry cleaners opened to a sidewalk that
    ran along the northern property boundary directly adjacent to the soil
    excavations for the former waste oil tank; (4) surface drainage ran from the
    adjacent property containing the dry cleaners towards the CBI property; (5) PCE
    contamination was surficial and present at the greatest levels on the adjacent
    property; (6) PCE concentrations increased with the distance away from the
    former waste oil tank; (7) samples collected on the adjacent property had high
    levels of PCE and "a distinct dry cleaning solvent odor"; and (8) the dry cleaners
    had reportedly replaced its dry-cleaning machine.
    On October 5, 2007, DEP issued an NFA letter and covenant not to sue,
    informing Peter that no further action was necessary for the remediation of
    contamination caused by the USTs. However, the NFA did not encompass the
    PCE contamination found on the CBI property.
    The letter stated that the PCE found on the CBI property "is from an
    unknown source unrelated to the [waste oil tank area of concern]." "In order to
    identify any areas of concern that may be contributing to the noted
    contamination, or alternatively, confirm that the source of this PCE
    A-1793-18
    27
    contamination is from off-site, a Preliminary Assessment pursuant to N.J.A.C.
    7:26E-3, is necessary."
    In July 2008, Envirotactics collected eight soil samples and three
    groundwater samples on the CBI property to determine the effect of PCE on the
    groundwater. Neuffer testified that the additional work was done because a
    purchaser was interested in the property.
    In a letter to Peter dated August 4, 2008, Envirotactics reported that the
    PCE contamination was the result of a discharge from the adjacent Constantinou
    property, and that the groundwater was significantly impacted. Due to the high
    levels of contamination on the adjacent property and the depth of groundwater
    contamination on the CBI property, Envirotactics concluded that "it d[id] not
    appear feasible to remediate the subject property without also remediating the
    contaminated soil located offsite to the north."        This letter was the last
    involvement Envirotactics had with the CBI property.
    In January 2009, DEP's Bureau of Underground Storage Tanks (Bureau)
    sent a notice of deficiency letter to Peter, identifying the failure to remediate a
    discharge and to submit a preliminary assessment report in the required format .
    In February 2012, the Bureau notified CBI of its failure to comply with
    the MOA and to evaluate and remediate the PCE on its property. The letter
    A-1793-18
    28
    noted that counsel for the Clarke Brothers had informed DEP that CBI did not
    intend to address the previously reported violations. It advised CBI that "based
    upon the investigation conducted to date, contaminants which are not normally
    related to the material stored in the UST(s) have been detected in the soil and
    groundwater on-site." The Bureau also informed CBI that it had to conduct a
    remedial investigation of groundwater unless it could demonstrate that the
    contamination came from an off-site source with no on-site contribution to show
    CBI was exempt from liability under the Spill Act.
    The Constantinou Property and Remediation
    In light of the information received from Neuffer regarding the
    Constantinou property, DEP sent a notice of deficiency to Lim and Michael
    Constantinou in January 2009 advising they had failed to remediate the PCE
    discharge. The letter stated that PCE was "a chemical not related to petroleum
    products sold or used at the Gulf Service Station, but was commonly used by
    dry cleaners." DEP required a vapor intrusion investigation to collect vapor
    samples from the soil and air to determine if levels of contamination were above
    the DEP cleanup guidelines. It also required a work plan that included proposals
    for sub-slab and indoor air sampling, and directed Atlantic Cleaners to enter into
    an MOA to address the contamination.
    A-1793-18
    29
    In March 2009, the Constantinous retained Practical Environmental
    Solutions, LLC to conduct a vapor intrusion investigation at the shopping center .
    A vapor intrusion system, approved by DEP, was eventually installed in the dry
    cleaners building.
    The Constantinous also retained Stantec, an engineering and consulting
    company, which performed additional sampling to delineate the extent of the
    soil contamination and to characterize the groundwater on and off-site. A soil
    sampling taken in front of the CBI service building detected a low concentration
    of PCE.     Sampling also identified elevated levels of PCE in the soil and
    groundwater in the location of the dry cleaners. Stantec opined that a discharge
    of PCE at Atlantic Cleaners caused the contamination near its building.
    The Constantinous subsequently hired another environmental company to
    remediate the soil of PCE contamination both on their own property and on the
    CBI site.
    Neuffer's Expert Testimony at Trial
    Neuffer earned a Bachelor of Arts degree in industrial engineering and a
    Master's degree in environmental science.         He worked for DEP in its
    Environmental Cleanup and Responsibility Act department and then for a
    private consulting company where he performed site investigations and
    A-1793-18
    30
    remediation. In 1995, he started his own company – Envirotactics. He was
    certified by DEP for subsurface investigations and closures of USTs, registered
    by the National Registry of Environmental Professionals as an environmental
    property assessor, and certified by the Institute of Hazardous Materials
    Management as a hazardous materials manager. In 2010, Neuffer became a
    DEP-licensed site remediation professional (LSRP), which allowed him to "sign
    off and close environmental cases."6
    Neuffer was qualified by the court as an expert in the field of
    environmental sciences, including "the assessment and investigation of not only
    the source of location of the contaminant but all of the geological and hydro
    geological aspects of migration."
    Neuffer testified that PCE was "a chlorinated volatile organic" that had a
    "specific gravity that's heavier than water and it's a typical chemical that's used
    in dry cleaning applications." He characterized PCE as a known hazardous
    substance and a carcinogen that required disposal by a licensed facility or
    reclamation recycling.
    6
    Neuffer testified that the LSRP program replaced DEP's NFA letter for site
    remediation cases.
    A-1793-18
    31
    Neuffer explained the first excavation conducted in February 2006 was in
    the area of the waste oil tank because when that tank was removed, there were
    holes in the tanks. He needed to take soil samples to assure DEP that the
    contaminated soil was completely removed. Neuffer testified he did not expect
    to find PCE in the soil because it had not been found in the area of the waste oil
    tank, and because Peter had denied using PCE "in his parts cleaning" or "as a
    parts degreaser or anything." A second deeper excavation continued to reveal
    PCE contamination.
    Neuffer told the court that he suspected the PCE contamination was
    coming from "off site." He therefore took soil samples from under the fence
    situated along the CBI/Manasquan Plaza property boundary.           The samples
    detected PCE, with the highest level of contamination coming from a sample
    taken from under the fence outside the rear door of the dry-cleaning operation.
    Neuffer opined that a surface discharge at the adjacent dry cleaners was
    the source of the PCE contamination on the CBI property. He gave the following
    reasons: Peter denied using a chlorinated solvent on his property, whereas the
    dry cleaners used PCE; the soil samples collected near the dry cleaners smelled
    like solvents used for dry-cleaning; the concentrations of PCE were highest in
    soil samples taken outside the rear of the dry cleaners and decreased in all
    A-1793-18
    32
    directions from there; the topography sloped downward from the dry cleaners
    towards the CBI property; and the highest level of groundwater contaminants
    were detected directly behind Atlantic Cleaners.
    Neuffer also noted that PCE was detected underneath the dry-cleaning
    facility, but not under the CBI service building, that PCE was the only
    contaminant detected in the area away from the waste oil tank, and that the dry
    cleaners had recently replaced their machinery.       He further noted that the
    consultants who performed excavations on the Constantinou property concluded
    that there was a discharge of PCE from the dry cleaners.
    Neuffer did not believe the PCE leaked from holes in the waste oil tank.
    He explained that PCE was usually detected in soil samples taken close to the
    surface, whereas the holes in the tank were below the surface. He also stated
    that PCE contamination would not travel from a greater depth to the surface, and
    that no PCE was detected in the area of the tank holes. He conceded he did not
    know the history of the waste oil tank or observe its piping, which could
    sometimes leak.
    As stated, Neuffer relied on Peter's testimony that CBI did not use solvents
    to wash auto parts. He admitted he did not know the scope of vehicle repairs
    performed by CBI or whether CBI performed brake work, and he did not
    A-1793-18
    33
    investigate prior operations on the property.      Neuffer stated he knew that
    solvents were used in auto repair work and that such products could contain PCE
    and conceded that CBI might have used small quantities of chlorinated solvents
    for cleaning parts or brakes. Nevertheless, even if CBI used small amounts of
    spray can solvents, Neuffer said he would not change his conclusion as to the
    source of the contamination.
    Neuffer testified that he visually observed the properties and said:
    it was plain to see that the sidewalk was definitely
    higher than the level that was on the . . . other side of
    the fence. So it dropped off . . . [n]ot substantially, but
    then it was a gradual gradient away from this property
    toward the Clarke Brothers.
    In Neuffer's opinion, the PCE migrated downgradient with rainwater from
    the Constantinou property onto the CBI property, and entered the ground
    vertically and horizontally. He said this explained why the soil sample with the
    highest level of PCE contamination was not found outside the dry-cleaning store
    but was found on CBI property.
    Neuffer did not know exactly how the discharge or spill occurred but said
    it could happen a "wide variety of ways." For example, based on his prior
    experience with PCE, spent solvents from a dry-cleaning operation sometimes
    were stored outside the rear door and could spill. "There could be waste water
    A-1793-18
    34
    from mopping floors where there was a spill and you could discharge that out
    the back." Likewise, "if you had filters from the dry cleaning machine or
    something if they were stored outside and rain water got on them, it could cause
    PCE to come out of the filters."
    Although Neuffer never saw filters outside the rear of the dry cleaners, he
    said there were a "wide variety of potential ways that PCE could have been
    discharged to the surface." He noted that the samples taken by Stantec detected
    no PCE in the soils below CBI's service building, but found PCE in the soil
    samples taken below the slab floor of the dry cleaners, with the highest
    concentration at the rear of the cleaning facility. Moreover, he relied on Peter,
    who told him the dry cleaners had replaced its machinery.
    On cross-examination, Neuffer acknowledged that he did not measure the
    exact topography of the properties and did not know the gradient of the CBI
    property before 2006. Nor did he ask any of the property owners for information
    about the topography. He also did not know what CBI used the sheds and trailer
    for or whether prior owners used the waste oil tank.
    Neuffer explained that CBI did not ask him to prepare a preliminary
    assessment report or a phase I investigation, which would have provided
    information regarding the historical use of the properties. If he had done so, he
    A-1793-18
    35
    would have looked at the site history back to 1932 or when it was "naturally
    vegetated." However, he stated that he did not need to look at any other sources
    of information because his investigation focused on determining whether the
    dry-cleaning operation was the source of the contamination.
    Neuffer acknowledged he had no personal information about a discharge
    of PCE from Atlantic Cleaners. He assumed the discharge occurred after the
    building was constructed because the spill was surficial. He did not see a
    discharge occur and neither Peter nor anyone else reported a discharge to him .
    He also never visited the dry cleaners, other than as a customer. He never saw
    where the cleaners kept the dry-cleaning equipment and did not ask O'Connor
    to see the record of PCE usage. In fact, he never had a conversation with
    O'Connor when he was conducting his investigation.
    Neuffer further acknowledged that auto repair facilities commonly used
    solvents. However, he never investigated whether the activities on the CBI
    property caused or contributed to the PCE contamination on its property.
    Neuffer advised that at some point after "all the reports" were prepared,
    he became aware that CBI used spray cans containing chlorinated solvents. He
    did not know when or how CBI used the products or the amount they used. He
    admitted making no determination regarding CBI's use of the spray cans. He
    A-1793-18
    36
    acknowledged that the use of spray cans of chlorinated solvents constituted the
    use of solvents, but explained that he did not think it was a potential source for
    the contamination.
    When shown a receipt from an auto parts store that reflected CBI's
    purchase of a solvent, Neuffer did not recall seeing it before. He stated he did
    not inform DEP that the references in his reports about the non-use of
    chlorinated solvents were inaccurate, explaining the use of these spray cans did
    not affect the conclusions in the reports that he submitted or the "tank work ."
    Neuffer was questioned about specific soil samples. He testified that the
    sample taken from the waste oil tank excavation site, about ten feet from the end
    of the CBI service building, which detected PCE, was subject to dilution at the
    laboratory by a factor of 500% during testing. He did not know why the lab
    diluted the sample and could not say if or how the dilution affected the
    quantitative result. He did not place this sample on his isopleth map. Neuffer
    acknowledged that if the results without dilution had shown a higher
    concentration of PCE, they would have contradicted his opinion. Specifically,
    he acknowledged that if the soil sample had a much higher concentration of PCE
    than depicted in his reports, then "yeah, this isopleth would be totally different ."
    A-1793-18
    37
    IV.
    In a comprehensive written opinion dated October 29, 2018, Judge Perri
    reviewed the factual findings and assessed the credibility of the witnesses.
    Judge Perri noted that Peter was the primary source of information
    regarding the Clarke's operation of its business and the use of its property. She
    stated that when his videotape deposition was conducted in December 2009,
    Peter was suffering from stage four renal cancer and had undergone extensive
    radiation and chemotherapy treatments. She described him as "very weak and
    frail. It was the court's impression that Peter's physical condition contributed to
    his inability to give credible, reliable testimony." The court found Peter could
    not recall the sequence of important events and did not seem to have the energy
    to give thought to the questions being asked. Therefore, she "put little credence
    in the accuracy of Peter's recollection or testimony, particularly with regard to
    critical liability issues."
    Judge Perri also found that Neuffer was not a credible witness, explaining
    that he could not provide details on critical issues, he avoided responding
    directly to questions, he appeared "noticeably uncomfortable," he gave
    inconsistent testimony about Meridian's initial soil samples, he accepted Peter's
    A-1793-18
    38
    bare statement that CBI did not use solvents, and he did not satisfactorily answer
    questions on cross-examination.
    The judge noted that "out of an abundance of caution" she qualified
    Neuffer "by virtue of his training and experience to offer opinions on matters of
    site   investigation,   remediation     and   determination   of   the    source   of
    contamination." However, after listening to Neuffer's testimony, despite his
    qualifications, Judge Perri found "Neuffer offered no real technical or scientific
    testimony at trial regarding the properties of PCE or how it interacts with the
    environment." She noted that his reports and his testimony did not address the
    specific properties of the chemical. The court also found that Neuffer did not
    offer testimony or modeling to explain, "on a chemical or physical level, how
    PCE would travel through rainwater over the ground or how its pro perties 'can
    affect travel and impact.'" In addition, the judge stated Neuffer did not discuss
    the effect of rainwater or the elements on PCE after it was introduced into the
    environment, "or correlate any such changes in the concentrations of PCE
    detected on both properties."
    The judge stated that Neuffer:
    relied on such 'unscientific' bases for his opinion as his
    visual observation of a 'gradual downward slope' from
    the [Manasquan Plaza] property to the CB[I] property,
    which he opined permitted PCE to be transported by
    A-1793-18
    39
    rainwater to the CB[I] property. Even in this regard, he
    did not offer any data or measurements to support his
    opinion. He did not obtain a survey or perform any tests
    that would identify the actual slope of the property nor
    did he offer any evidence that the slope was sufficient
    to permit rainwater to travel to the other locations on
    the CB[I] property where PCE was detected. He did
    not explain how the topography or ground cover would
    impact on the manner and direction in which water
    would flow from the one property to the other which
    might explain the random nature of the deposits.
    Judge Perri found these deficiencies and omissions affected "the weight and
    credibility that can be afforded to Neuffer's opinions." She elaborated that
    "Neuffer's willingness to accept Peter's bare statement that CB[I] did not use
    solvents in its auto repair business and his failure to perform any investigation
    of the historical use of the CB[I] property, casts serious doubt on the validity of
    his expert opinion."
    The judge noted that the CBI property was used as a gas station before
    CBI purchased it, that CBI did not perform any environmental investigations
    prior to its purchase, and that it continued to operate a gas station and auto repair
    service on the property for thirty years before PCE was detected. Furthermore,
    [d]espite Neuffer's knowledge of CB[I]'s casual attitude
    toward environmental contamination, as evidenced by
    the decision to simply spread the stockpiled
    contaminated soil on the property rather than disposing
    of it properly, Neuffer accepted at face value Peter's
    representation that CB[I] did not use solvents in its auto
    A-1793-18
    40
    repair business and relied on that fact in forming his
    opinion.
    In addition, when Neuffer was confronted on cross-examination with the sales
    receipt establishing CBI's purchase of aerosol cans of solvents, she stated he
    "became hesitant and evasive."      She also found Neuffer's credibility was
    diminished when he was unsure when or how he found out CBI did use spray
    solvents and in his concession that he did not advise DEP of the information.
    Judge Perri further found that Neuffer's credibility was undermined by his
    "equivocal attempts" to explain why he did not perform a preliminary
    assessment of the property. She stated he appeared "noticeably uncomfortable
    when questioned about the failure to perform a [preliminary assessment]" and
    that he testified unconvincingly that he did not recall whether "he told Peter
    about the obligation to perform a [preliminary assessment]," despite repeated
    demands to do so by DEP. The court noted that if Neuffer had prepared a
    preliminary assessment and researched the historical use of the CBI property
    and other potential sources of PCE, it would have enabled him and DEP "to
    eliminate CB[I] as a potential source of the PCE contamination." The judge
    concluded that Neuffer or Peter "made an informed decision not to perform a
    [preliminary assessment], which might disclose CB[I]'s own responsibility for
    the contamination."
    A-1793-18
    41
    Moreover, the court found inconsistencies in Neuffer's testimony
    regarding the soil samples collected by Meridian in 2000.         She noted that
    Neuffer testified that Meridian scanned one of the samples for PCE and none
    was found, which contradicted the March 2006 report in which he wrote that
    this sample was only analyzed for TPH.
    Additionally, the court found Neuffer's explanation for the exclusion from
    his isopleth map and exhibits of the first soil sample taken from the CBI property
    that detected PCE, "less than credible." The judge noted Neuffer did not discuss
    "any anomalies" regarding the sample until cross-examination, when he
    acknowledged that the sample had a dilution factor of 500%. The court also
    noted, that in his report, Neuffer wrote that the sample had a PCE level of 120
    ppm, without mentioning the undiluted reading. Notably, the court found that
    "[i]f in fact the undiluted reading had been included on the isopleth map, it
    would have substantially skewed the map 'results' and demolished Neuffer's
    theory."
    Judge Perri determined that Neuffer based his opinion on three facts that
    were not supported by credible evidence.          First, he assumed the PCE
    contamination came from the adjacent property because CBI did not use
    solvents, which was disproven.      Second, he assumed the dry cleaners had
    A-1793-18
    42
    purchased a new dry-cleaning machine around the time the PCE contamination
    was discovered on the CBI property and relied on this assumption to prove the
    discharge came from the dry cleaners. But there was no evidence of a change
    in equipment at Atlantic Cleaners at that time.       Third, he assumed a spill
    occurred at the dry cleaners and that the PCE was carried by rainwater onto the
    CBI property, with no scientific support or attempt to identify the degree of
    slope that led to the movement of the substance.
    Therefore, the judge concluded that Neuffer offered a net opinion that
    could not support plaintiffs' claims. She stated further that, "[e]ven assuming
    that the opinion [was] not barred as a net opinion, the court would find that
    Neuffer's testimony on many key issues, as set forth above, was not sufficiently
    credible to support a finding that plaintiff had proven causation by a
    preponderance of the credible evidence."7 The court dismissed plaintiffs' claims
    and entered judgment in favor of defendants.
    V.
    On appeal, plaintiffs argue that the court erred in finding Neuffer's
    testimony was inadmissible net opinion; dismissing its claims against O'Connor;
    and in dismissing its ERA claims. We are not persuaded.
    7
    The court also considered and rejected plaintiffs' ERA claim.
    A-1793-18
    43
    A.
    In considering Neuffer's testimony and opinions, we turn to N.J.R.E. 703
    as the foundational rule for expert testimony. Townsend v. Pierre, 
    221 N.J. 36
    ,
    53 (2015). This rule requires experts to support their opinions with "facts or
    data derived from (1) the expert's personal observations, or (2) evidence
    admitted at the trial, or (3) data relied upon by the expert which is not necessarily
    admissible in evidence but which is the type of data normally relied upon by
    experts." 
    Ibid.
     (quoting Polzo v. Cnty. of Essex, 
    196 N.J. 569
    , 583 (2008)).
    A corollary to N.J.R.E. 703 is the net opinion rule, which "forbids the
    admission into evidence of an expert's conclusions that are not supported by
    factual evidence or other data." Id. at 53-54. It requires an expert to "'give the
    why and wherefore' that supports the opinion, 'rather than a mere conclusion.'"
    Id. at 54 (quoting Borough of Saddle River v. 66 E. Allendale, LLC, 
    216 N.J. 115
    , 144 (2013)). An expert's opinion is inadmissible if it is "'based merely on
    unfounded speculation or unquantified possibilities.'"         Id. at 55 (quoting
    Grzanka v. Pfeifer, 
    301 N.J. Super. 563
    , 580 (App. Div. 1997)). An expert also
    renders an inadmissible net opinion if the expert fails "to explain a causal
    connection between the act or incident complained of and the injury or damage
    allegedly resulting therefrom." Koruba v. Am. Honda Motor Co., 396 N.J.
    A-1793-18
    44
    Super. 517, 526 (App. Div. 2007); see Townsend, 221 N.J. at 57-58 (holding
    expert's testimony was net opinion to extent he speculated on causation by
    failing to apply his engineering expertise to present empirical evidence and by
    reconstituting facts). Experts must "be able to identify the factual bases for their
    conclusions, explain their methodology, and demonstrate that both the factual
    bases and the methodology are reliable." Townsend, 221 N.J. at 55 (quoting
    Landrigan v. Celotex Corp., 
    127 N.J. 404
    , 417 (1992)). Thus, "a trial court must
    ensure that an expert is not permitted to express speculative opinions or personal
    views that are unfounded in the record." Ibid.; see Koruba, 396 N.J. Super. at
    526 (experts must "be able to point to a generally accepted, objective standard
    of practice and 'not merely to standards personal to the witness'") (quoting
    Fernandez v. Baruch, 
    52 N.J. 127
    , 131 (1968)).
    The net opinion rule, however, does not require an expert to support or
    organize an opinion in a manner preferred by opposing counsel. Townsend, 221
    N.J. at 54. Moreover, a court should not exclude an expert's testimony merely
    because it does not account for a particular fact or condition that opposing
    counsel considers relevant. Ibid. An expert who fails to give weight to a factor
    deemed important by an adverse party does not render an inadmissible net
    A-1793-18
    45
    opinion if the expert offers sufficient reasons that logically support the opinion.
    Ibid. Such an omission is a proper subject for cross-examination. Id. at 54-55.
    The admission or exclusion of evidence lies in the sound discretion of the
    trial court. Id. at 52. We apply a "deferential approach to a trial court's decision
    to admit expert testimony, reviewing it against an abuse of discretion standard."
    Id. at 53 (quoting Pomerantz Paper Corp. v. New Cmty. Corp., 
    207 N.J. 344
    ,
    371-72 (2011)).
    We also defer to a trial judge's credibility determinations.       Cesare v.
    Cesare, 
    154 N.J. 394
    , 412 (1998); Reese v. Weis, 
    430 N.J. Super. 552
    , 567 (App.
    Div. 2013). "Such deference is appropriate because the trial judge has 'a feel of
    the case' and is in the best position to 'make first-hand credibility judgments
    about the witnesses who appear on the stand.'" Reese, 430 N.J. Super. at 567-
    68 (quoting N.J. Div. of Youth & Fam. Servs. v. E.P., 
    196 N.J. 88
    , 194 (2008)).
    Plaintiffs presented Neuffer as their liability expert.         His ultimate
    conclusion was that the source of PCE contamination on the CBI property was
    the dry-cleaning operation at the adjacent shopping center. Our review of his
    extensive testimony reflects this opinion was not supported by the facts or any
    explained reliable methodology. Instead, Neuffer's testimony on the cause of
    the PCE contamination was speculative and based on his personal opinions.
    A-1793-18
    46
    As Judge Perri found, Neuffer did not provide any objective data to
    support his theory that rainwater carried PCE downhill from the dry cleaners to
    the CBI property. He acknowledged that he did not know how or when a
    discharge or spill occurred at the dry-cleaning facility, and he could not confirm
    that CBI did not use chlorinated solvents in its auto repair work.
    Neuffer relied on three unfounded "facts" to support his causation opinion.
    First, he assumed the PCE contamination came from the adjacent dry cleaners
    because CBI did not use chlorinated solvents in the operation of its business.
    However, he did not investigate the history of the CBI property, did not know
    the contents of the waste oil tank during the years of use by the former owners,
    and did not confirm Peter's statement that CBI did not use PCE. He testified
    that CBI never asked him to prepare a preliminary assessment but said such an
    investigation was not necessary because his work focused on determining
    whether the dry cleaners was the source of contamination. Despite the letter
    from DEP requiring the assessment, Neuffer claimed there was no indication in
    any documents that such an assessment was necessary. And he did not believe
    that a preliminary assessment would have changed his opinion.
    Moreover, Neuffer did not investigate Peter's claim that he and his brother
    never used PCE in their auto repair business, even though he conceded at trial
    A-1793-18
    47
    that auto repair facilities used chlorinated solvents and that after "all the reports
    were prepared," he became aware that CBI used spray cans that contained these
    solvents. Although Neuffer did not know when or how CBI used chlorinated
    solvents, or the amount or number of spray cans used over the years, he did not
    "think that having a spray can that may contain PCE would be a potential source
    for the contamination we identified." He never told DEP about the use of
    chlorinated solvents on the CBI property, although he knew the references in his
    reports about the non-use of chlorinated solvents was inaccurate.              Thus,
    Neuffer's assumption that CBI did not use PCE on its property was not supported
    by the factual evidence.
    Second, Neuffer assumed Atlantic Cleaners obtained a new dry-cleaning
    machine around the time of the discovery of the PCE contamination on the CBI
    property.   He apparently believed this change in equipment was due to a
    discharge of PCE. He relied on the replacement of the machine as one of the
    eight reasons supporting his opinion that the chlorinated solvent contamination
    was due to the adjacent dry-cleaning operation, and included this "fact" in his
    May 2006 remediation report, and in its August 2006 remediation investigat ion
    report addendum.
    A-1793-18
    48
    Neuffer, however, never visited the dry cleaners, other than as a customer,
    and never inspected the dry-cleaning equipment or saw the rear of the shop
    where the owners kept it. He also never spoke to O'Connor or anyone else at
    the time who worked at the dry cleaners, and never asked to see the records
    maintained by O'Connor for the dry-cleaning operations. Most importantly, Lim
    testified that he replaced the dry-cleaning machine in July 2012 – many years
    after the PCE was first detected on the CBI property. Moreover, Lim stated he
    replaced the dry-cleaning machine with one that used a non-hazardous cleaning
    substance and that he supplanted the machine because it was "old and wearing
    down." There was no evidence in the record that he replaced it because of a
    discharge of PCE at his dry-cleaning facility. Thus, Neuffer's testimony about
    the reason for the replacement of the dry-cleaning machine was speculative and
    unsubstantiated by any facts in the record.
    Third, Neuffer assumed there was a discharge of PCE on the property of
    the dry cleaners and that the PCE was carried by rainwater onto the CBI
    property. He stated he followed the contamination gradient from the off-site
    source, found no indication of another source within that gradient, and observed
    that contamination levels continually decreased as they moved towards the CBI
    property.
    A-1793-18
    49
    Judge Perri found Neuffer provided no "scientific support for this
    hypothesis," that he failed to identify "the degree of the 'gradual slope' between
    the properties that would have permitted the transfer to occur," and that he did
    not explain how the migration of PCE led to "the levels plotted on the isopleth
    map." We cannot disagree.
    Neuffer primarily relied on test results from soil samples taken on the two
    properties. He explained that a sample taken near the rear door of the dry
    cleaners indicated the presence of PCE at a level of 12,138 ppm, whereas the
    highest concentration of PCE on the CBI property "[r]ight under the fence line"
    was 393 ppm. When questioned, he acknowledged that a sample taken closest
    to the dry cleaners' rear door showed a PCE level of 850 ppm, saying "the
    numbers don't decrease exactly from the rear of the door."
    Neuffer believed the isopleth map he created supported his opinion by
    showing that the PCE concentration increased closer to the dry cleaners,
    explaining its gradients matched the land's topography. However, he did not
    include the sample taken from the excavation of the waste oil tank and located
    only several feet from the CBI service building which detected PCE in excess
    of 12,000 ppm. He acknowledged that if he had included that sample on the
    A-1793-18
    50
    map, the "isopleth would be totally different." As the trial court described, this
    testimony was "the most devastating attack on Neuffer's credibility."
    Neuffer's opinion on the downward gradient from the dry cleaners to the
    CBI property was based on his visual observation of the two properties in 2006.
    He explained: "[J]ust visually observing the property, it was plain to see that the
    sidewalk was definitely higher than the level that was . . . on the other side of
    the fence." He did not investigate whether there were any changes in the
    gradient over time.
    Neuffer relied on the gradient to explain the PCE found on the CBI
    property. However, both O'Connor and Michael Constantinou testified that for
    a long period of time the Constantinou property had a lower topography than its
    neighbor. O'Connor recalled that from 1997 through May 2007, water would
    flow after rainstorms from the CBI property to the rear door of his cleaners.
    Michael recalled that the topography changed after the Clarke brothers
    excavated some of the soil on their property, which left the Constantinou
    property higher by about two inches.        There is no evidence that Neuffer
    consulted topographic maps, soil surveys, or groundwater site maps in reaching
    his conclusion about the gradient or spread of the PCE contamination. Nor did
    he consider the contrary testimony of other witnesses.
    A-1793-18
    51
    In Neuffer's opinion, the PCE "spread out with rainwater" even where the
    gradient was "close to level." He testified that PCE was denser than water and
    tended to migrate vertically and then horizontally at greater depths, but he also
    claimed that the contamination on the CBI soil traveled horizontally from
    surface runoff. However, as stated by the trial court, Neuffer did not explain
    how PCE would travel through rainwater over the ground, address how its
    properties could affect "travel and impact," or discuss "the effect that rainwater
    or the elements would have on PCE" after its introduction into the environment .
    He therefore did not support his opinion with any scientific data or explanation.
    The record also supports the trial court's determination that Neuffer was
    not a credible witness on key issues such as the source of the PCE contamination
    and how and why it migrated to the CBI property. For example, he could not
    explain why the specific soil sample with unfavorable readings for CBI was
    excluded from the isopleth map or why the lab diluted the sample. He also
    testified that in 2000, after removing the waste oil tank, Meridian conducted soil
    sampling that detected TPH and based on that result, it "ran an analysis for
    volatile organics" and detected xylene, but not PCE. In contrast, Envirotactics
    reported in 2006 that Meridian collected one soil sample from the area of the
    waste oil tank, which was analyzed only for TPH.
    A-1793-18
    52
    We are satisfied the court did not err in finding Neuffer rendered a net
    opinion by inferring causation of the source of the PCE contamination without
    supporting facts, scientific data, or methodology.
    B.
    Plaintiffs argue that the court erred in dismissing their claims against
    O'Connor.     They contend O'Connor was personally liable for the PCE
    contamination under the tort participation theory, and that the operation of a dry
    cleaners was an abnormally dangerous activity. Again, we disagree.
    At the conclusion of plaintiffs' case, O'Connor's counsel moved for his
    dismissal, arguing there was no evidence he engaged in any tortious conduct and
    that he did not act in a personal capacity outside of his role as principal of Silver
    Hanger. In granting the dismissal, Judge Perri stated there was no evidence to
    suggest "O'Connor in any way was involved in or instrumental in moving either
    PCE or PCE contaminated products out of the building to the location near the
    back door where plaintiffs' expert identified the principal spill." She explained:
    All of the contamination claims at issue in this case are
    with regard to soil contamination. And according to
    Neuffer, that contamination emanated from discharges
    or spills that occurred outside of the leasehold for the
    dry cleaner, but on the premises owned by the
    Constantinou[s].
    A-1793-18
    53
    So I find that there has been no evidence presented even
    under the rigorous standard under Rule 4:37-2(b) from
    which a reasonable fact finder could conclude that John
    O'Connor was personally involved in the discharge of
    PCE in a location where plaintiffs' expert has identified
    it as having been migrated from the Constantinou
    property to the Clarke Brothers property.
    That is not to say that there may not ultimately be some
    consideration of liability with regard to Silver Hanger
    Manasquan by virtue of the actions of those non-
    testifying witnesses. And the [c]ourt may draw
    inferences with regard to that.
    Following the ruling, plaintiffs' counsel requested an opportunity to brief
    the issue of whether O'Connor could be held personally liable. The court granted
    the request.
    The next day, after additional oral argument on the issue, the court again
    found that plaintiffs had not proven O'Connor was personally liable under the
    participation theory for any discharge. Relying on Saltiel v. GSI Consultants,
    Inc., 
    170 N.J. 297
     (2002), the court concluded that plaintiffs did not sustain their
    burden to show that O'Connor took part in the commission of a tort by the
    corporation and that, "under the facts and circumstances of this case," there was
    no other basis to impose personal liability on him.
    A-1793-18
    54
    The court also found there was no evidence that the operation of a dry
    cleaner was an abnormally dangerous activity or that the use of the commercially
    available PCE was an abnormally dangerous activity.
    At the close of a plaintiff's case, a defendant "may move for a dismissal
    of the action or of any claim on the ground that upon the facts and upon the law
    the plaintiff has shown no right to relief." R. 4:37-2(b). The standard for an
    involuntary dismissal is whether "the evidence, together with the legitimate
    inferences therefrom, could sustain judgment in plaintiff's favor." 
    Ibid.
     Where
    reasonable minds can differ, accepting as true the evidence supporting the
    position of the non-moving party, and giving that party the benefit of all
    reasonable and legitimate inferences, the court must deny the motion.
    Verdicchio v. Ricca, 
    179 N.J. 1
    , 30 (2004). The court is not concerned with the
    worth, nature or extent of the evidence, but only with its existence viewed most
    favorably to the party opposing the motion. Dolson v. Anastasia, 
    55 N.J. 2
    , 5-6
    (1969). We apply the same standard. Craggan v. IKEA USA, 
    332 N.J. Super. 53
    , 61 (App. Div. 2000).
    The Spill Act provides that "any person who has discharged a hazardous
    substance, or is in any way responsible for any hazardous substance, shall be
    strictly liable, jointly and severally, without regard to fault, for all cleanup and
    A-1793-18
    55
    removal costs no matter by whom incurred." N.J.S.A. 58:10-23.11g(c)(1); N.J.
    Dep't of Envtl. Prot. v. Dimant, 
    212 N.J. 153
    , 175 (2012). The Spill Act defines
    a discharge as "any intentional or unintentional action or omission resulting in
    the releasing, spilling, leaking, pumping, pouring, emitting, emptying or
    dumping of hazardous substance into the waters or onto the lands of the State,
    or into waters outside the jurisdiction of the State when damage may result to
    the lands, waters or natural resources within the jurisdiction of the State."
    N.J.S.A. 58:10-23.11b. Although the Spill Act does not define the phrase "in
    any way responsible," the Supreme Court has interpreted it to mean "ownership
    or control over the property at the time of the discharge." Dep't of Env't Prot.
    v. Ventron Corp., 
    94 N.J. 473
    , 502 (1983).
    Plaintiffs argue that the plain language of the Spill Act imposes personal
    liability on O'Connor because he had ownership or control over Atlantic
    Cleaners at the time of a discharge of PCE. O'Connor, however, did not own or
    control Manasquan Plaza or the Constantinou property. Moreover, although he
    was aware of several instances of a PCE leak inside the containment tank
    surrounding the machine, he testified there were no discharges of PCE into the
    environment during the years he operated Atlantic Cleaners. Any leaks noted
    A-1793-18
    56
    were enclosed in the containment tank. The record contains no evidence to the
    contrary.
    Plaintiffs further argue that, because a dry-cleaning facility is an
    abnormally dangerous activity, O'Connor is strictly liable for damages resulting
    from the PCE contamination on the CBI property. Because O'Connor was
    strictly liable, plaintiffs contend they are not required to establish fault.
    Plaintiffs' reliance on Ventron to support its argument is misplaced.
    In Ventron, the Court held that "those who use, or permit others to use,
    land for the conduct of abnormally dangerous activities are strictly liable for
    resultant damages." 
    Id. at 488
    . In that case, the defendant corporations dumped
    toxic mercury into a nearby creek, and the defendant Ventron expressly assumed
    the liability of one of them. 
    Id. at 493
    .
    Adopting the analysis in the Restatement (Second) of Torts § 520 (1977),
    the Court stated that whether an activity was abnormally dangerous was
    determined on a case-by-case basis after taking into consideration the following
    factors:
    (a) existence of a high degree of risk of some harm to
    the person, land or chattels of others;
    (b) likelihood that the harm that results from it will be
    great;
    A-1793-18
    57
    (c) inability to eliminate the risk by the exercise of
    reasonable care;
    (d) extent to which the activity is not a matter of
    common usage;
    (e) inappropriateness of the activity to the place where
    it is carried on; and
    (f) extent to which its value to the community is
    outweighed by its dangerous attributes.
    The Ventron Court concluded that "mercury and other toxic wastes were
    'abnormally dangerous,' and the disposal of them, past or present, is an
    abnormally dangerous activity." Id. at 493. See T&E Indus., Inc. v. Safety Light
    Corp., 
    123 N.J. 371
    , 391, 394-95 (1991) (holding, under facts of case, the
    defendants were strictly liable for harm caused by their "processing, handling,
    and disposal" of radium).
    Unlike Ventron, the operation of a dry-cleaning business does not qualify
    as an abnormally dangerous activity given its "common usage," "value to the
    community" and appropriateness of the activity to "the place where it is carried
    on." See Restatement (Second) of Torts § 520 comment f ("In determining
    whether the danger is abnormal, the factors listed in Clauses (a) to (f) . . . are all
    to be considered, and are all of importance.").
    A-1793-18
    58
    Moreover, O'Connor testified that Silver Hanger bought a containment
    tank from the manufacturer of the dry-cleaning machine to catch leaks,
    conducted daily measurements of PCE in the air, kept records of purchases and
    disposal of PCE, and recorded leaks in inspection logs. He and the other
    employees also received training on the use of the machinery.         Thus, the
    likelihood of harm was not great.        Plaintiffs have not demonstrated the
    applicability of any of the enumerated factors to categorize a dry-cleaning
    business as an abnormally dangerous activity.
    C.
    Plaintiffs also contend the court erred by rejecting their argument that
    O'Connor was personally liable under the tort participation theory.         They
    contend that he participated or cooperated in the commission of a tort by Silver
    Hanger, and that he should not "escape the consequences of his individual
    wrongdoing by saying that he acted on behalf of a corporation."
    In Saltiel, the defendant corporation entered into a contract with the
    plaintiff to design and prepare specifications for turf grass on athletic fields.
    
    170 N.J. at 299
    . The plaintiff alleged the corporation was negligent in preparing
    and designing the specifications and that its officers were personally liable
    because they participated in the corporation's tort. 
    Ibid.
     The sole issue on
    A-1793-18
    59
    appeal was whether the court erred by granting summary judgment in favor of
    the corporate officers. 
    Id. at 302
    . To resolve the issue, the Court considered:
    "(1) the proper application of the participation theory of personal liability for
    tortious conduct by corporate officers under New Jersey law; and (2) whether
    the plaintiff's claim against [two corporate officers] sounds in tort or contract."
    
    Ibid.
    The Court noted that the "essence" of the participation theory is "that a
    corporate officer can be held personally liable for a tort committed by the
    corporation when he or she is sufficiently involved in the commiss ion of the
    tort." 
    Id. at 303
    . It explained that "a predicate to liability is a finding that the
    corporation owed a duty of care to the victim, the duty was delegated to the
    officer and the officer breached the duty of care by his own conduct." 
    Ibid.
    Under this theory, a corporate officer can be held individually liable for tortious
    conduct committed by the corporation if he or she participated in that conduct
    and it resulted in injury to the plaintiff. 
    Id. at 309
    .
    The Court observed that most New Jersey cases applied the participation
    theory to intentional torts such as fraud or conversion and that the theory also
    applied to certain statutory violations. 
    Id. at 304-05
    ; see Allen v. V. & A. Bros.,
    
    208 N.J. 114
    , 136 (2011) (holding individual liability for violation of Consumer
    A-1793-18

    Fraud Act depended on evaluation of specific source of claimed violation and
    particular acts undertaken by individual); Van Natta Mech. Corp. v. Di Staulo,
    
    277 N.J. Super. 175
    , 191 (App. Div. 1994) (holding corporate officer acting on
    behalf of corporation was liable to persons injured by his or her own torts). The
    Saltiel Court, however, held that the theory did not apply where breach of the
    corporation's duty was governed by contract law. 
    Id. at 309, 318
     (holding
    participation theory inapplicable because contract law governed duty of
    corporate officers).
    Here, plaintiffs presented no evidence that Silver Hanger or O'Connor
    participated in negligent conduct.    They do not cite actions performed by
    O'Connor that constituted a breach of any duty owed by the corporation.
    Instead, they argue that he operated Atlantic Cleaners for more than a decade
    during which time he used PCE, and that he was "intimately involved in its
    management and operation." They note that O'Connor handled, stored and
    removed the PCE, that he oversaw "the management, oversight, and
    implementation of policies concerning same," that he performed routine
    maintenance on the dry-cleaning machine, and that he was in "exclusive
    possession of the premises during the time the PCE was discharged and
    discovered."

    However, O'Connor testified without contradiction that there were
    policies for daily monitoring and handling of PCE, and that employees were
    required to confirm their compliance by way of a "checklist." He stated that
    every day the operator felt around the machine and looked underneath it for
    leaks, inspected the pipe connections, fittings, couplings and valves, along with
    the filter gaskets, solvent tanks, containers, and waste separator, and performed
    daily leak inspections using a halogen detector. O'Connor also testified that
    government authorities inspected the dry-cleaning machine over the years and
    never cited Silver Hanger for noncompliance. Plaintiffs' conclusory arguments
    that O'Connor participated in a tort are without any basis in the record. The trial
    court did not err in dismissing plaintiffs' claims against O'Connor individually.
    D.
    Plaintiffs also contend the court erred in dismissing their claims asserted
    under the ERA. Because we have determined that plaintiffs cannot sustain their
    claims without expert evidence and the expert opinion rendered was net opinion
    and not grounded in fact, there was no basis to support an ERA claim. In
    addition, plaintiffs were not seeking to enforce environmental laws or pursuing
    declaratory relief or civil penalties pursuant to the ERA. See N.J.S.A. 2A:35A-
    4(a). They were seeking damages for the decreased value of their property,

    v. Borough of Medford Lakes,
