Our Environmental Litigation team combines deep trial experience with unsurpassed regulatory insight as well as in-house scientific and technical professionals to successfully navigate high-stakes enforcement actions, citizen suits, and complex litigation involving the full range of environmental media. Several critical differentiators set us apart from other environmental litigation firms:

• A deep bench of environmental lawyers who try cases in courts across the country.
• Trial experience across all statutory regimes and environmental media.
• In-house toxicologists, medical doctors, and other scientists.
• Experience resolving high-stakes, bet-your-business litigation.
• Experience on the cutting edge of litigation involving emerging contaminants, climate change, and other novel claims. 

Trial-tested Environmental Team 

Few law firms combine environmental enforcement, regulatory, and permitting capabilities with actual trial experience. Our lawyers litigate bet-the-company matters rooted in complex environmental regulatory frameworks, including claims involving chemical exposure and operational emissions. We have successfully defended clients through trial, including achieving a complete defense verdict in the first multi-plaintiff ethylene oxide case in the United States, as well as serving as lead litigation counsel in a major Clean Water Act enforcement action involving alleged long-term permit exceedances.

Deep Experience in Emissions, Groundwater, and Toxic Exposure Claims

Our lawyers have extensive experience defending claims alleging exposure to air emissions and groundwater contamination from manufacturing, sterilization, smelting, and generating facilities. We are deeply familiar with Clean Air Act permitting and monitoring requirements, human health risk assessments, air quality dispersion modeling, and the scientific evidence underlying claims of respiratory injury and other alleged health effects. We also advise on a broad spectrum of Clean Water Act matters, both in litigation before trial courts and on appeal. We regularly litigate matters involving a wide range of substances, including ethylene oxide (EtO), PCBs, mercury, lead, arsenic, hydrocarbons, benzene, TCE, PCE, TCA, Paraquat, PFAS, asbestos, talc, MTBE, and other alleged contaminants. 

Integrated Legal and Scientific Approach

In cases involving novel or complex science, we deploy integrated teams of litigators and lawyer‑scientists. Several of our lawyers hold advanced science and engineering degrees, supported by scientific specialists with MDs, PhDs, and other advanced scientific and technical credentials help ensure that legal strategy is grounded in rigorous science.

Litigation Implicating Complex Environmental Regulations 

We represent clients in high-stakes, multi-jurisdictional litigation involving complex environmental regulatory frameworks, including mass tort, NEPA, climate change, and Proposition 65 matters. 

Our work also extends to litigation focused on common law tort claims such as nuisance, negligence, and trespass allegedly caused by emissions, noise, groundwater contamination, runoff, stormwater, odor, exposure to hazardous substances, and incidents. 

State Attorney General Matters 

We defend clients in high-stakes investigations and litigation brought by State Attorneys General and multi-state coalitions, often involving allegations of environmental contamination, consumer protection violations, and emerging regulatory theories. These matters frequently span multiple jurisdictions and include claims for remediation, natural resource damages, and related personal injury, property damage, and economic loss.

Climate Change and Stormwater Litigation 

We guide clients through complex climate change and stormwater disputes, including enforcement actions, citizen suits, and regulatory investigations. We have deep, on‑the‑ground experience in jurisdictions such as California, work directly with environmental groups to resolve concerns, and advise regulators on enforcement priorities. We advise data center developers on the emerging challenges around water use, generator emissions, climate and sustainability claims, community concerns, and potential litigation involving common law tort claims.
