For decades, WilmerHale has counseled clients through complex legal issues involved in the management of hazardous and non-hazardous waste streams and the cleanup and restoration of contaminated sites.

Our environmental lawyers help clients ensure compliance with federal, state and local statutes and processes that govern the generation, transportation, treatment and disposal of hazardous and solid waste and the restoration of natural resources, including the Resource Conservation and Recovery Act, Natural Resources Damage Assessment, and related state programs. We also represent clients in actions, including contribution claims, under the Oil Pollution Act, Clean Water Act, Clean Air Act, and Comprehensive Environmental Response, Compensation and Liability Act (CERCLA)—or Superfund law—brought by federal, state and local agencies, including the Environmental Protection Agency (EPA), and private parties. We have extensive experience defending claims for the restoration of public resources and groundwater in all phases of natural resource damage assessments under CERCLA, the Clean Water Act, the Oil Pollution Act, and related state authorities. Our team, which includes a former senior Department of Justice civil environmental prosecutor and skilled litigators who represent individual and groups of potentially responsible parties in disputes over the proper allocation of cleanup responsibility, has developed innovative solutions to difficult legal issues at many of the biggest cleanup sites in the United States.
