On July 9^th, 2025, the Eastern District of New York ruled on a series of motions in Suffolk County Water Authority v. Dow Chemical Company, a case brought by the Suffolk County Water Authority (“Suffolk”) against chemical manufacturers for the alleged contamination of Suffolk’s groundwater supply with 1,4-dioxane (“dioxane”), a chemical classified by the EPA as a “probable human carcinogen.”  Judge Gershon issued an opinion allowing most of the plaintiff’s common law tort claims to proceed to trial while clarifying the standard for expert admissibility under recently amended Federal Rule of Evidence 702.

On January 2, 2024, the United States District Court for the Eastern District of Michigan issued an order to exclude the expert testimony of Dr. Robert Michaels in a series of cases related to the corrosive water in Flint, Michigan. Carthan, et al. v. Snyder et al, No. 5:16-cv-1044 (E.D. Mich. 2024). The court held that Dr. Michaels, in applying a methodology commonly employed by epidemiologists known as the Bradford Hill guidelines, failed to establish an association between corrosive water and skin and hair conditions, and without such, the testimony was unreliable and could not be used to infer causation between Flint water and reported skin rashes and hair loss.  Read More »

On Monday, July 29, 2019, the New Jersey Supreme Court held that an arbitrator’s decision dismissing a property owner’s claim for coverage under the Spill Compensation Fund was arbitrary and capricious because the decision was procedurally and substantively flawed. US Masters Residential Property (USA) Fund v. N.J. Dept. of Envt’l Prot., __ A.3d __, 2019 WL 3402917 (N.J. 2019) (slip opn.). The Court’s 4-3 opinion suggests that despite the deference afforded arbitrators in these cases, they remain subject to a searching judicial review. Read More »

On April 9, 2019, Judge John Z. Lee of the District Court for the Northern District of Illinois, Eastern Division denied the City of Evanston’s motion for a preliminary injunction against two utility companies in a RCRA action that sought to compel the utility companies to investigate and remediate polycyclic aromatic hydrocarbon (PAH) contamination in the area.  After a lengthy evidentiary hearing spanning eight days, Judge Lee found that the city had failed to meet its overall burden of proving likelihood of success on the merits, in part because he believed one of the city’s main theories of contamination to be “simplistic.”  (Memorandum Opinion and Order, at *4, City of Evanston v. Northern Illinois Gas Company, No. 16 C 5692 at *19 (N.D. Ill. Apr. 9, 2019)). And on May 16, 2019, the Seventh Circuit Court of Appeals affirmed a similar decision in Varlen Corporation v. Liberty Mutual Insurance Company, No. 17-3212 (7^th Cir. May 16, 2019), excluding an expert witness and granting summary judgment to the defendant because the expert's testimony regarding the cause of contamination was found to be unreliable, having failed to meet the Daubert standard.

On January 4, 2019, the Superior Court of New Jersey, Appellate Division, affirmed a Middlesex County trial court order holding that judicial estoppel is a valid defense to contribution claims under the New Jersey Spill Compensation and Control Act (the “Spill Act”), at N.J.S.A. 58:10-23.11 to 23.24. The case, Terranova et al., v. Gen. Elec. Pension Trust et al., N.J. Super. App. Div.

Last month, a district court in the Northern District of California held on motions for summary judgment that Technichem, Inc., a hazardous waste management company, was liable under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) for PCE contamination, but that the issue of whether an employee was also considered an “operator” under CERCLA could not be resolved on summary judgment.  The case, Department of Toxic Substances Control v. Technichem, Inc. et al, Case No. 12-cv-05845-VC (N.D. Cal, March 15, 2016), was decided by United States District Judge Vince Chhabria.     Read More »

On Friday, the Pennsylvania Superior Court issued a non-precedential opinion that affirmed a trial court’s order denying objections filed by natural gas drilling company, Range Resources-Appalachia, LLC, to a subpoena issued to one of its engineering consultants, URS Corp. The case, Haney v. Range Resources-Appalachia, LLC, et al., No. 2012-3534, involves personal injury and property damage claims filed by a group of residents that live near Range’s Yeager natural gas drilling site in Washington County, Pennsylvania.   Read More »

In the 2012 case of New Jersey Schs. Dev. Auth. v. Marcantuone, 428 N.J. Super. 546 (App.Div. 2012), the New Jersey Appellate Division held that a passive landowner who purchased contaminated property prior to the enactment of the New Jersey Spill and Compensation Act (“Spill Act”) was a liable party under the Act even if the owner did not contribute to the contamination, unless it could meet the Spill Act’s definition of an “innocent purchaser.”  This decision gave rise to an entirely new wave of litigation against landowners who, previously, were not thought to be PRPs under the Spill Act.  Last week, however, the Appellate Division of the Superior Court of New Jersey returned some hope to these property owners when it affirmed a Superior Court decision holding that, while a passive landlord is a  liable party under the Spill Act, application of the equitable principles of allocation may result in a finding that such a landlord is nevertheless 0% responsible  for the costs of remediation.   Read More »

Since the United States Supreme Court decided Wal-Mart Stores, Inc. v. Dukes, 131 S.Ct. 2451 (2011), plaintiffs in contamination cases have struggled to meet the raised bar for class certification.  And that bar was certainly not lowered by the Seventh Circuit in its decision in Parko v. Shell Oil Co., Nos. 13-8023 & 13-8024 (7^th Cir. Jan 17, 2014).  Parko involved a putative class comprised of property owners in the town of Roxana, Illinois, who claimed that their property values had been diminished by benzene contamination of the groundwater from an adjacent oil refinery which had been in operation for nearly 100 years.  In checking off the certification requirements, the district court held that the question of whether the multiple defendants who owned and operated the refinery during the preceding 90 plus years failed to “contain petroleum byproduct [resulting] in contamination to Roxana property” predominated.   The Seventh Circuit panel unanimously disagreed.  Judge Posner, writing for the Court, described the opinion as necessary for clarification of a trial court’s responsibility to conduct a “rigorous analysis” of whether common issues predominate; in doing so, he did not hesitate to take the district judge to task for “treat[ing] predominance as a pleading requirement” rather than an evidentiary one.  Read More »

I love dissents.  While majority opinions focus on legal analysis, as they should, dissents tell the story, because it is usually only in the context of the story that the legal analysis of the majority can be directly attacked.  Such is the case with the recent en banc decision by the Pennsylvania Superior Court in Barrick v. Holy Spirit Hospital, 2011 Pa. Super. 251 (2011).  But more on the dissent later. Read More »
