William J. Walsh is a partner in the Washington, D.C. office of Lewis Brisbois and a member of the Environmental & Administrative Law Practice. He principally focuses his practice in the areas of government policy advocacy, regulatory compliance and counseling and environmental litigation. Bill advises companies and industry trade associations on compliance with wide range of environmental laws (including the Toxic Substance Control Act, the Federal Insecticide Fungicide, and Rodenticide Act (FIFRA), the Clean Water Act, the Resource Conservation and Recovery Act, the California Safe Drinking Water and Enforcement Act (commonly referred to as Proposition 65), and the California Safer Consumer Product (SCP) regulations, among other statutes and regulations). Bill assists clients in identifying and mitigating business risks associated with increasingly complex product safety and chemical ingredient regulations developed pursuant to these environmental statutes and various product safety statutes (e.g., the Consumer Product Safety Act, the National Highway Safety Act). He also defends regulatory enforcement actions and personal injury/property damage liability litigation. He advocates changes to environmental regulations and policies and provides counsel on a broad range of environmental issues involving innovative scientific, regulatory, legal and policy questions. Bill is listed in Chambers USA: America’s Leading Lawyers for Business.

Prior to joining Lewis Brisbois, Bill was an associate, partner, and eventually Of Counsel at one major U.S. based law firm (from 1986 to 2016) and a Senior Counsel at another major law firm (from 2016 through 2019). Prior to that, Bill served as the chief of the Environmental Protection Agency’s (EPA) Drinking Water and Wetlands Enforcement Branch and was lead EPA counsel on the precedent-setting hazardous waste lawsuits brought against Occidental Chemical Corporation concerning the Love Canal and related landfills.

Bill has served on more than 13 NAS Committees, including Committees that authored reports on Alternatives for Ground Water Cleanup (1994) and Alternatives for Managing the Nation's Complex Contaminated Groundwater Sites (2013), evaluations of the hazardous waste remediation process and the limits to remediation technology.

Bill has written and spoken on a wide range of topics, including regulation and cleanup levels, choosing cleanup goals and technologies, the use of groundwater models in the regulatory system, and the distinction between personal injury claims and regulatory limits.
