Overview

BCLP has particular depth in the environmental field and we offer a leading environmental practice committed to balancing social, environmental and economic concerns. For more than 30 years, our lawyers have represented clients facing a broad range of environmental issues and challenges, including environmental compliance counseling, litigation, liability management, strategic planning and stewardship. The technical skills of our environmental lawyers combine with a multidisciplinary approach to offer clients an exceptional, comprehensive service. Our practice methods are deliberately solution-orientated and geared towards treating environmental law practice as a means to client’s ends rather than as an end in itself. 

The lawyers who practice environmental law at BCLP have the experience and reach to assist clients in the wide variety of matters they face in the field, in the courtroom and at the negotiating table. The hallmarks of our practice are deep technical knowledge in environmental and occupational health and safety law, a record of success in the litigation and trial of significant environmental and related insurance-coverage lawsuits (including group/class actions and mass torts), and advising on major projects of international, national and regional importance that raise complex environmental issues. We help our clients to navigate through the intricacies of environmental law and policy, including nature conservation, environmental impact assessment, environmental regulatory issues, dispute resolution and the environmental aspects of real estate and corporate transactions. Delivering solutions to environmental problems that confront owners of contaminated land, and developers of regeneration projects on brownfield land, also remains a core part of our business. 

Our lawyers are well aware that it is often essential for corporate and other institutional clients to maintain a working relationship and reputation for integrity, cooperation and environmental excellence with regulators and other public stakeholders. Our lawyers have many years of experience working with agencies and other stakeholders to represent clients effectively and with appropriate sensitivity to their reputational interests.  

Lawyers in the Environmental Practice Group represent the firm’s clients over the full spectrum of environmental and occupational safety and health matters. Please visit our associated environment pages to view more specific areas of our experience.

PFAS in groundwater: state-by-state regulations

In the absence of federal cleanup standards for per- and polyfluoroalkyl substances (“PFAS”) in groundwater, several states have started the process of regulating PFAS in groundwater themselves. As a result, states have adopted a patchwork of regulations and guidance standards that present significant compliance challenges to impacted industries. This client alert explores the current landscape of state regulations regarding the advisory, notification, and cleanup levels for PFAS – typically perfluorooctane sulfonic acid (“PFOS”) and perfluorooctanoic acid (”PFOA”) – in groundwater.

Manufacturers, distributors, and retailers of consumer products across a broad spectrum of industries are being impacted by state laws regulating the presence of per- and polyfluoroalkyl substances (“PFAS”) in their products. This area is rapidly developing as states create new laws or amend existing ones, and the penalties and litigation risks for non-compliance can be significant.

PFAS drinking water standards: state-by-state regulations

The regulation of per- and polyfluoroalkyl substances (“PFAS”) in drinking water remains one of the primary focuses for legislatures and agencies at both the state and federal levels.  In May 2025, the United States Environmental Protection Agency (“EPA”) affirmed Maximum Contaminant Levels (“MCLs”) of 4 parts per trillion (“ppt”) for two PFAS substances, perfluorooctanoic acid (“PFOA”) and perfluorooctane sulfonic acid (“PFOS”).  Many states have already regulated PFAS compounds in drinking water but have done so in a variety of different ways and at different levels.  The result is a patchwork of regulations and standards which presents significant operational and compliance challenges to impacted drinking water systems.  This client alert surveys  MCLs, as well as guidance and notification levels, for PFAS compounds in drinking water across the United States.
