    INTRODUCTION
    Plaintiffs and appellants Jennie Aguirre, Glenn DiCaro, Judy Gilleland, Rosemary
    Islava, Aliyah Islava, Ruth Linnea Karmelich, Ruben Lopez, and Olivia Santos
    (plaintiffs) brought an action against, inter alia, defendant and respondent Francine Rippy
    (defendant) concerning the alleged chemical contamination of their workplace.1 The trial
    court granted defendant’s motion for summary judgment (summary judgment motion)
    with respect to the fifth amended complaint. On appeal, plaintiffs contend that the trial
    court erred in granting summary judgment because there are triable issues of material fact
    as to their causes of action for negligence, strict liability for ultrahazardous activity, and
    public nuisance. Plaintiffs also contend that defendant failed to meet her burden of proof
    in demonstrating that they cannot establish causation and there is a triable issue of
    material fact with respect to causation. We affirm.
    BACKGROUND
    In their fifth amended complaint, plaintiffs asserted causes of action for
    negligence, strict liability for ultrahazardous activity, and public nuisance alleging that
    Omega Chemical Corporation (Omega) illegally stored and dumped chemicals on two
    parcels of land—12504 and 12512 Whittier Boulevard in the City of Whittier,
    California—that later became known as the Omega Chemical Superfund Site (Omega
    Site). Fred R. Rippy, Inc. owned the property at 12504 Whittier Boulevard from 1963
    until 1966 when it transferred its ownership interest to its then president Fred R. Rippy,
    defendant’s husband. In 1986, Mr. Rippy transferred ownership of 12504 Whittier
    Boulevard to the Fred R. Rippy Trust (Rippy Trust). Defendant and Mr. Rippy owned
    the property at 12512 Whittier Boulevard from about June 1984 to October 1986, when
    1     Plaintiffs alleged that Aliyah Islava’s mother Rosemary Islava worked in the
    workplace when Aliyah was in gestation.
    2
    they transferred the property to the Rippy Trust.2 From 1976 until 1987, Omega leased
    12504 Whittier Boulevard. In 1987, the Rippy Trust granted ownership of 12504 and
    12512 to Omega.
    According to plaintiffs, from 1976 to 1991, Omega operated a spent solvent and
    refrigerant recycling and treatment facility on the Omega Site. The facility treated
    commercial and industrial solid and liquid waste consisting of chlorinated and aromatic
    solvents and other hydrocarbons and chlorofluorocarbons and operated as a transfer
    station for the storage and consolidation of waste for shipment to other treatment and/or
    disposal facilities. The facility stored large quantities of waste on the property. The
    improper storage and handling of the waste, including leaking storage tanks and spills,
    resulted in contamination of the soil and groundwater. According to the Environmental
    Protection Agency (EPA), the toxic chemicals migrated through the soil as gas and
    entered adjacent buildings through cracks in basements, foundations, sewer lines, and
    other channels.
    Plaintiffs alleged that during the time that defendant owned 12512 Whittier
    Boulevard, the property had been and was contaminated, which contamination was
    visible in aerial photographs. Plaintiffs claimed that the spillage and staining on 12512
    Whittier Boulevard was caused or contributed to by Omega’s operations on that property
    or on 12504 Whittier Boulevard. They alleged that any reasonable, diligent property
    owner would have noticed and been aware of the significant spillage and staining on
    12512 Whittier Boulevard, and that defendant knew or should have known of the
    contamination
    According to plaintiffs, during the time that defendant owned 12512 Whittier
    Boulevard, the Los Angeles County Health Department sent a number of violation
    notices concerning soil and groundwater contamination at or around 12504 Whittier
    Boulevard caused by Omega’s operations. As owner of an adjacent property, defendant
    knew or should have known about the contamination and the public notices concerning
    2      Defendant may have retained some interest in the property as she released and
    quitclaimed her interest in the property to the Rippy Trust in September 1987.
    3
    12504 Whittier Boulevard and the effect that such contamination would have on her and
    other surrounding properties. Moreover, during defendant’s ownership of 12512 Whittier
    Boulevard, environmental investigative work was conducted on 12504 Whittier
    Boulevard, which investigative work found “ground/soil surface and subsurface
    contamination at the Omega Site.” Defendant knew or should have known about the
    investigative work.
    Defendant failed to investigate to determine the spread of the contamination to
    adjacent properties, plaintiffs claimed, despite having notice of the contamination and the
    need for such an investigation. Defendant had a duty to investigate and mitigate the
    contamination on her property.
    Except for Aliyah Islava, plaintiffs alleged that they worked at the Tri-Cities
    Regional Occupational Program (ROP), which occupied the property at 12519 East
    Washington Avenue (ROP Site) across the street from the Omega Site, and that they were
    exposed to chemicals that migrated from the Omega Site to the ROP Site through the soil
    and groundwater.3 Plaintiffs further alleged that defendant acquired ownership of the
    ROP Site in 1977 and leased it to the ROP from November 1998 to 2012. They
    contended that defendant had notice that the Omega Site contamination had reached the
    ROP Site but failed to investigate and mitigate the contamination on the property in a
    timely manner or to warn them of the foreseeable harm. As a result of the contamination
    to which they claimed they were exposed, plaintiffs alleged they suffered from the
    following: Ms. Aguirre—neuralgia, abnormal cells on her cervix, a two centimeter cyst
    in her ovary, Eagle Syndrome, and thyroid cysts; Mr. DiCaro—esophageal cancer; Ms.
    Gilleland—thyroid cancer, a cyst on her ovary, cervical discharge, breast cancer, and
    several lipoma tumors in her neck; Rosemary Islava—a severe rash, redness, and itching
    all over her body resulting in blisters during her pregnancy with Aliya; Aliya Islava—
    medulloblastoma (brain cancer); Ms. Karmelich—breast cancer and lymphoma in her
    3      See footnote 1 above.
    4
    lungs and bones; Mr. Lopez—benign tumors on his head and neck; and Ms. Santos—
    monoclonal gammopathy.
    According to plaintiffs, defendant was serving or had served as a board of
    directors board member, president, and chief executive officer (CEO) of Fred R. Rippy,
    Inc. She was Fred R. Rippy, Inc.’s CEO in 1998 when it leased the ROP Site to the ROP.
    As CEO, defendant would or should have known of investigations conducted by the EPA
    and by consultants hired by the Fred R. Rippy Trust and the results of those
    investigations. Defendant knew or should have known that the Omega Site was
    contaminated before Fred R. Rippy, Inc. leased the ROP Site to the ROP. Despite
    requests from the ROP “for such knowledge,” defendant failed to inform the ROP of the
    contamination. In 1999, defendant was aware of evidence that suggested that the use of
    chemicals and solvents at the Omega Site contributed to groundwater contamination that
    had spread “down-gradient” of the Omega Site and failed to inform the ROP.
    Despite her knowledge of the contamination, defendant failed to take any action to
    investigate or to assist in the investigation of the Omega Site or the ROP Site. She
    further failed to take any action to mitigate or remediate or to assist in any mitigation or
    remediation efforts at the Omega Site or the ROP Site. She also failed to notify the ROP,
    plaintiffs, or any of the ROP’s employees of the contamination.
    In light of the allegations in the fifth amended complaint, defendant moved for
    summary judgment asserting the following five undisputed material facts: (1) defendant
    never had an interest in, operations on, or the ability to control 12504 Whittier Boulevard
    or the ROP Site; (2) defendant’s only interest in 12512 Whittier Boulevard was as a joint
    tenant with her husband from June 7, 1984, through October 1, 1986; (3) during her
    ownership of 12512 Whittier Boulevard, defendant was never made aware that
    contamination from any source posed a threat to human health to persons within the
    buildings on the ROP Site, or likely would pose such a threat in the future; (4) defendant
    never released to soil or groundwater anywhere trichloroethylene, perchloroethylene,
    methylene chloride, or benzene; and (5) plaintiffs claimed adverse health effects were not
    caused by their exposures at the ROP Site to trichloroethylene, perchloroethylene,
    5
    methylene chloride, or benzene. Defendant repeated and relied on those same facts with
    respect to each of plaintiffs’ causes of action.
    In support of its summary judgment motion, among other evidence, defendant
    submitted a report from Barbara D. Beck, Ph.D., DABT (Diplomate, American Board of
    Toxicology), FATS (Fellow, Academy of Toxicological Sciences), a toxicologist who
    specialized in human health risk assessment. Dr. Beck performed hypothetical cancer
    and non-cancer risk assessments in accordance with EPA guidelines and toxicity criteria
    and California cancer and non-cancer toxicity levels using plaintiffs’ respective
    employment histories and indoor air data information for the ROP Site during the period
    from March 2010 to December 2012. She “[q]ualitatively and quantitatively evaluated
    the potential for causal associations between exposures to the [chemicals of concern4]
    and Plaintiffs’ claimed health effects.”
    Dr. Beck opined that the cumulative cancer risks—i.e., the sum of all risks posed
    by the chemicals of concern—did not exceed the EPA’s or California’s de minimis or
    “acceptable” risk ranges and the non-cancer risk did not exceed a “hazard index of 1, a
    level below which no adverse health effects [were] expected.” Dr. Beck’s findings
    supported the conclusion that the plaintiffs’ potential exposure to the chemicals of
    concern had “posed negligible cancer or non-cancer risks to any Plaintiff.”
    Dr. Beck also considered each plaintiff’s specific health claims, the plaintiff’s
    length of employment at the ROP Site, and where in the ROP Site the plaintiff worked.
    She then evaluated the potential for “causal associations” between exposure to the
    chemicals of concern and the plaintiffs’ claimed health effects. Based on her evaluations,
    she found that there was no “reliable qualitative and/or quantitative evidence that a causal
    association exist[ed] between Plaintiffs’ potential exposures to the [chemicals of concern]
    and the claimed health effects.” Dr. Beck “conclude[d], to a reasonable degree of
    scientific certainty, that it [was] highly unlikely that Plaintiffs’ potential exposures to [the
    chemicals of concern] in indoor air at the ROP . . . buildings could have caused or
    4     Dr. Beck identified the “chemicals of concern” as tetracholoroethylene (apparently
    another name for perchloroethylene), trichloroethylene, benzene, and methylene chloride.
    6
    actually caused their claimed health effects or could cause adverse health effects in the
    future. Furthermore, there [was] no reasonable basis to conclude otherwise.”
    Plaintiffs filed objections and a motion to strike all or parts of Dr. Beck’s
    declaration and report. The trial court did not expressly rule on plaintiffs’ objections, but
    implicitly overruled them as it relied on Dr. Beck’s report in ruling that there was no
    causal link between plaintiffs’ exposure to the chemicals at issue and plaintiffs’ maladies.
    In opposition to defendant’s summary judgment motion, plaintiffs submitted a
    declaration from Rob C. Hesse, a principal geologist with Soil Water Air Protection
    Enterprise (SWAPE), who reviewed the history and extent of hazardous waste releases
    from the Omega Site. In a declaration, Mr. Hesse opined that, based on the information
    he reviewed, “it is obvious that contamination should have been expected to be
    downgradient of the Omega Site as early as 1988, if not earlier.” Mr. Hesse stated, “it
    can be reasonably concluded that [defendant] had access to information and knowledge
    of possible hazards at the ROP . . . but failed to act responsibly by informing the ROP
    tenants and demanding that investigations be conducted to fully assess indoor air risks to
    ROP occupants.” Plaintiffs also submitted a supplemental declaration from Mr. Hesse.
    The supplemental declaration further addressed the issue of notice.
    Plaintiff submitted a report from Paul Rosenfeld, Ph.D., a SWAPE principal and
    an expert in the fields of environmental chemistry, risk assessment, contaminant exposure
    assessment, contamination investigation, remediation, ecological restoration, and
    epidemiological and statistical analysis, who evaluated the toxic air contaminants to
    which plaintiffs were exposed at the ROP Site and that addressed opinions Dr. Beck
    offered in her report. Dr. Rosenfeld criticized Dr. Beck’s report because the opinions
    expressed in it concerning historical exposure at the ROP Site were based on indoor air
    monitoring data collected after March 2010, which data primarily included results for
    tests performed after mitigation actions were taken at the site. According to Dr.
    Rosenfeld, Dr. Beck’s report did not consider historic chemical concentrations in the
    ROP Site from 1999 to 2010. Dr. Rosenfeld stated that vapor intrusion modeling
    demonstrated that plaintiffs were historically exposed to concentrations of contaminants
    7
    inside the ROP Site buildings that greatly exceeded the levels that Dr. Beck supposed
    were present and upon which she based her evaluation. He concluded, therefore, that Dr.
    Beck’s analysis was inadequate and unreliable for assessing plaintiffs’ exposures.
    Plaintiffs also submitted a report from Vera S. Byers, M.D., Ph.D., an expert in the
    fields of environmental toxicology, pharmaceutical toxicology, autoimmune diseases,
    exposure of populations to a variety of industrial chemicals including trichloroethylene,
    perchloroethylene, and methylene chloride, who opined on the source of plaintiffs’
    maladies using contamination exposure levels provided by SWAPE. As to Aliyah Islava,
    Dr. Byers concluded that “Rosemary Islava’s exposure to the [perchloroethylene,
    tricholorethylene] and methylene chloride at her workplace caused or substantially
    contributed to her daughter Aliyah Islava’s medulloblastoma.” With respect to Rosemary
    Islava, Dr. Beck stated, “It is my opinion to a reasonable medical probability that the
    prolonged exposure of Mrs. Islava to [tricholorethylene] at her workplace was the cause
    or a substantial factor contributing to her severe rash.”
    With respect to Ms. Gilleland’s and Ms. Karmelich’s breast cancer, Dr. Byers
    stated, “In conclusion there is definitely a causal association between exposure to the
    three chlorinated hydrocarbons under discussion in this case and breast cancer. I
    conclude that exposure to the three chlorinated hydrocarbons in this case was a factor in
    the development of breast cancer suffered by these two women.” Dr. Byers opined that
    “to a reasonable degree of medical certainty that Ms. Santos’s exposure to the chemicals
    in question in this case caused or substantially contributed to her [monoclonal
    gammopathy].”
    As for Mr. DiCaro’s esophageal cancer, Dr. Byers opined “to a reasonable degree
    of medical certainty that the exposure to the chemicals in question in this case was a
    factor in Mr. DiCaro’s esophageal cancer. Given, however, the smoking history in this
    case, I am unable to quantitate the significance of this factor.” With respect to Ms.
    Aguirre’s peripheral neuropathy, Dr. Byers stated, “there is a causal association between
    exposure to the three chlorinated hydrocarbons under discussion in this case and
    peripheral neuropathy. Without further information I am unable to opine on the
    8
    significance of Ms. Aguirre’s exposure to the chemicals in question in this case in the
    causation of her peripheral neuropathy.” Dr. Byers concluded, “to a reasonable degree of
    medical certainty that the workplace exposure to the chlorinated hydrocarbons especially
    [tricholorethylene] caused or substantially contributed to the Monday morning headaches
    suffered by Mr. Lopez” when he went to work and opened up the ROP.
    Defendant filed objections to Mr. Hesse’s declaration and supplemental
    declaration and Dr. Rosenfeld’s report. Defendant also filed objections to Dr. Byers’s
    report. Based on the appellate record plaintiffs provided, it appears that plaintiffs did not
    file responses to defendant’s objections. The trial court did not rule on the objections to
    Mr. Hesse’s declaration and supplemental declaration and Dr. Rosenfeld’s report and
    sustained the objections to Dr. Byers’s report. Plaintiffs do not challenge on appeal the
    trial court’s ruling sustaining defendant’s objections to Dr. Byers’s report.
    The trial court granted defendant’s summary judgment motion. In its discussion
    of plaintiffs’ negligence cause of action, it stated that Dr. Beck’s testimony “to a
    reasonable degree of scientific certainty, that ‘it is highly unlikely that Plaintiffs’
    potential exposures . . . . could have . . . caused their claimed health effects . . . ’” was
    credible. It further stated that “Plaintiffs’ evidence is insufficient to raise a triable issue
    as to causation.”
    DISCUSSION
    Plaintiffs contend that there are triable issues of material fact as to their causes of
    action for negligence, strict liability for ultrahazardous activity, and public nuisance.
    They also contend that defendant failed to meet her burden of proof in demonstrating that
    they cannot establish causation and there is a triable issue of material fact with respect to
    causation. We hold that defendant met her burden of proof in demonstrating that
    9
    plaintiffs cannot establish causation and there is no triable issue of material fact with
    respect to causation.5
    I.     Standard of Review
    “Summary judgment is granted when the moving party demonstrates that there is
    no triable issue as to any material fact and that the moving party is entitled to a judgment
    as a matter of law. (Code Civ. Proc., § 437c, subd. (c).) A defendant moving for
    summary judgment meets its burden of showing that there is no merit to a cause of action
    by showing that one or more elements of the cause of action cannot be established or that
    there is a complete defense to that cause of action. (Code Civ. Proc., § 437c, subd.
    (p)(2).) We review an appeal of a summary judgment de novo, as the appeal only
    involves legal issues. (State of California v. Allstate Ins. Co. (2009) 
    45 Cal. 4th 1008
    ,
    1017 [
    90 Cal. Rptr. 3d 1
    , 
    201 P.3d 1147
    ].)” (Greene v. Bank of America (2015) 
    236 Cal. App. 4th 922
    , 932.)
    II.    Causation
    Plaintiffs contend that the trial court improperly placed the burden on them of
    demonstrating causation and failed to consider whether defendant made a prima facie
    showing that there were no triable issues of material fact with respect to causation. In
    addition to that error, plaintiffs contend, the trial court erred in failing to find that they
    demonstrated a triable issue of material fact with respect to causation.
    A.      Defendant Made a Prima Facie Showing That There Are No Triable Issues
    of Material Fact as to Causation
    A defendant has met its burden of showing that there is no merit to a cause of
    action and thus is entitled to summary judgment by showing that one or more elements of
    5       Because we hold that plaintiffs cannot demonstrate causation, we need not reach
    their claims that there are other triable issues of material fact as to their causes of action
    for negligence, strict liability for ultrahazardous activity, and public nuisance.
    10
    a cause of action cannot be established. (Code Civ. Proc., § 437c, subd. (p)(2); Greene v.
    Bank of 
    America, supra
    , 236 Cal.App.4th at p. 932.) Causation is an element in every
    tort action. (C.A. v. William S. Hart Union High School Dist. (2012) 
    53 Cal. 4th 861
    ,
    876.)
    Plaintiffs contend that the trial court failed to consider whether defendant made a
    prima facie case that they could not prove causation. They claim that defendant failed to
    make such a case because defendant’s expert, Dr. Beck, was not qualified to offer
    conclusions about plaintiffs’ medical conditions because she was a toxicologist and not a
    medical doctor, her report lacked a foundation because she provided a conclusion on
    causation without any basis or analysis, and she failed to consider plaintiffs’ long-term
    exposure and based her analysis on contamination levels beginning in March 2010.
    Apparently, plaintiffs contend that the trial court erred in failing to exclude Dr. Beck’s
    report. Whether we review the trial court’s implicit rejection of plaintiffs’ objections to
    Dr. Beck’s report de novo or under an abuse of discretion standard (see Reid v. Google,
    Inc. (2010) 
    50 Cal. 4th 512
    , 535), the trial court properly considered the report.
    Dr. Beck did not testify as an expert in medicine and thus did not render her
    opinion on causation to a “‘“reasonable medical probability.”’” (See Bockrath v. Aldrich
    Chemical Co. (1999) 21 Cal.4th. 71, 79, italics added.) Rather, she testified as an expert
    in science and opined “to a reasonable degree of scientific certainty, that it [was] highly
    unlikely that Plaintiffs’ potential exposures to [the chemicals of concern] in indoor air at
    the ROP . . . buildings could have caused or actually caused their claimed health effects
    or could cause adverse health effects in the future.” (Italics added.) Dr. Beck was
    qualified to render that opinion. She was a Fellow and Past President of the Academy of
    Toxicological Sciences and a Visiting Scientist in the Department of Environment Health
    at the Harvard School of Public Health. She had been a Regional Expert in Toxicology
    and Chief of the Air Toxics Staff at Region 1 of the EPA. She became a Diplomate of
    the American Board of Toxicology—i.e., board certified—in 1988, and specialized in
    human health risk assessment. In ruling that plaintiffs could not establish causation, the
    trial court found credible Dr. Beck’s opinion to a reasonable degree of scientific certainty
    11
    that it was highly unlikely that plaintiffs’ potential exposures to the chemicals of concern
    could have caused their claimed health effects. A trial court has “considerable latitude in
    determining the qualifications of an expert and its ruling will not be disturbed on appeal
    unless a manifest abuse of discretion is shown.” (People v. Kelly (1976) 
    17 Cal. 3d 24
    ,
    39, abrogated by statute on another point as explained in People v. Wilkinson (2004) 
    33 Cal. 4th 821
    , 845-848.)
    There was a sufficient foundation for Dr. Beck’s report. In Dr. Beck’s detailed
    report, she stated that she relied on case-specific documents such as medical records,
    questionnaires, depositions, air quality data, complaints, and Dr. Byers’s and Dr.
    Rosenfeld’s declarations; general guidance documents in the fields of toxicology and
    risks assessment by the EPA, Agency for Toxic Substances and Disease Registry
    (ATSDR), and the California Environmental Protection Agency; environmental and
    regulatory documents that included toxicity criteria and secondary toxicological reviews
    of the chemicals of concern; and scientific literature on toxicology, epidemiology, and
    risk assessment of the relevant chemicals.
    As set forth above, Dr. Beck performed hypothetical cancer and non-cancer risk
    assessments in accordance with EPA guidelines and toxicity criteria and California
    cancer and non-cancer toxicity levels using plaintiffs’ respective employment histories
    and indoor air data information for the ROP Site during the period from March 2010 to
    December 2012. She considered each plaintiff’s specific health claims, the plaintiff’s
    length of employment at the ROP Site, and where in the ROP Site the plaintiff worked.
    She then evaluated the potential for “causal associations” between exposure to the
    chemicals of concern and the plaintiff’s claimed health effects.
    In that evaluation, relying on ATSDR toxicological profiles for the chemicals of
    concern, she first “evaluated qualitatively whether scientific evidence exist[ed] to support
    a causal relationship between exposures to the [chemicals of concern] and claimed health
    effects under any conditions.” Next, she “compared the highest UCLM [upper
    confidence limit of the mean] exposure concentrations in the ROP building to [chemicals
    of concern]-specific health-based toxicity criteria (reference concentrations, or RfCs) and
    12
    points of departure (PODs). The RfC is an estimate (with uncertainty spanning perhaps
    an order of magnitude) of continuous inhalation exposure to the human population
    (including sensitive subgroups) that is likely to be without an appreciable risk of
    deleterious effects during a lifetime . . . . PODs are ‘the dose-response point that marks
    the beginning of a low-dose extrapolation’ . . . to a cancer or non-cancer toxicity
    criterion. For air contaminants, the POD is traditionally the lowest concentration at
    which adverse effects have been observed in humans or animals, or the highest
    concentration at which no adverse effects have been observed. To evaluate the potential
    for non-cancer effects, [she] compared UCLM exposure concentrations to the RfC and
    POD from which the RfC was derived. . . . To evaluate the potential for cancer effects,
    [she] compared UCLM exposure concentrations to the POD serving as the starting point
    for deriving US EPA inhalation cancer criteria (i.e., inhalation unit risks).”
    In reaching her conclusions, Dr. Beck considered historic chemical exposure
    levels. Dr. Beck relied on indoor air data from several rooms in the ROP taken from
    March 2010 to December 2012. She then calculated the maximum value for each
    chemical of concern for each room. Based on that data, she conducted a hypothetical risk
    assessment for the following scenario: a full-time worker at the ROP for 14 years who
    was exposed at all times to the highest UCLM concentration for each chemical of
    concern. Dr. Beck’s use of actual indoor air data and maximum exposure levels for each
    chemical properly considered historic levels of chemical contamination.
    Plaintiffs also argue that the trial court held them to an improperly high standard
    of proof on summary judgment. Instead, plaintiffs argue, they were only required to raise
    a triable issue of material fact as to the causal connection between the alleged
    contaminants and their asserted maladies. The trial court did not hold plaintiffs to an
    improperly high standard in opposing defendant’s summary judgment motion. With
    respect to each of plaintiffs’ causes of action, the trial court expressly stated in its ruling
    that plaintiffs failed to establish a material issue of fact. Thus, the trial court applied the
    correct standard in ruling on defendant’s summary judgment motion.
    13
    B.      Plaintiffs Failed to Demonstrate a Triable Issue of Material Fact as to
    Causation
    In its ruling granting summary judgment, the trial court stated with respect to
    plaintiffs’ negligence cause of action, “In connection with defendant Fred Rippy’s prior
    motion for summary judgment, the Court found Dr. Beck’s testimony [i.e., her
    conclusion, to a reasonable degree of scientific certainty, that ‘it is highly unlikely that
    Plaintiffs’ potential exposures . . . could have . . . caused their claimed health effects . . .’]
    to be credible. At the same time, the Court sustained objections to the testimony
    provided by Plaintiffs’ expert, Dr. Vera Byers. Defendant’s objections are likewise
    sustained here. Dr. Byers’ statements re ‘reasonable medical probability’ are conclusory
    only, and are improperly based on ‘associations’ between exposure and certain illnesses,
    and speculative SWAPE opinions re the degree and duration of exposure. There is
    nothing before the Court in the instant motion to change the Court’s rulings re those
    objections. Thus, Plaintiffs’ evidence is insufficient to raise a triable issue as to
    causation.”6 Plaintiffs contend that the trial court erred in granting defendant summary
    judgment based on its causation ruling because they showed a triable issue of material
    fact concerning causation.
    As plaintiffs explain in their reply brief, their evidentiary showing on causation
    consisted of two parts. First, Mr. Hesse and Dr. Rosenfeld provided evidence of the
    levels of chemical exposure that each of the plaintiffs suffered at the ROP Site. Second,
    based on that chemical exposure evidence, Dr. Byers “considered whether causal
    connections existed between Plaintiffs’ exposure to the subject chemicals and Plaintiffs’
    medical conditions or issues with their health.” Dr. Byers’s expert opinion was the only
    evidence that specifically addressed that aspect of causation—i.e., that addressed whether
    6       Although the trial court stated its ruling on causation in connection with plaintiffs’
    negligence cause of action, plaintiffs’ causation theory was the same as to each of their
    causes of action—i.e., exposure to the chemicals at issue in this case caused plaintiffs’
    maladies. Accordingly, the trial court’s causation ruling applied with equal force to
    plaintiffs’ causes of action for strict liability for ultrahazardous activity and public
    nuisance.

    there was a causal link between plaintiffs’ alleged exposure to the chemicals at issue in
    this case and plaintiffs’ asserted maladies. As set forth above, however, defendant
    objected to Dr. Byers’s report, plaintiffs did not respond to those objections, and the trial
    court sustained the objections. When the trial court sustained defendant’s objections to
    Dr. Byers’s report, Dr. Byers’s report was excluded from plaintiffs’ evidentiary showing.
    Plaintiffs have not challenged the trial court’s ruling on appeal. Accordingly, by failing
    to respond to the objections to Dr. Byers’s report in the trial court and by failing to
    challenge the trial court’s ruling on those objections on appeal, plaintiffs have forfeited
    any challenge to the trial court’s ruling. Without Dr. Byers’s opinion on causation,
    plaintiffs are unable to show that the trial court erred in finding that plaintiffs failed to
    show a triable issue of material fact and thus erred in granting defendant summary
    judgment.
    DISPOSITION
    The judgment is affirmed. Defendant is awarded its own costs on appeal.
