Matthew Cohn’s practice focuses on all aspects of environmental law, pairing his legal experience with a professional background in environmental science. His work includes litigation, environmental due diligence and counseling on regulatory compliance.

Issues Matt frequently litigates include CERCLA cost recovery and contribution cases, RCRA citizen suits, toxic tort cases, permitting and insurance coverage disputes, and enforcement actions for violations of air, water and waste laws. He also counsels businesses on Clean Air Act and Clean Water Act regulations and has managed due diligence projects including site assessments under the EPA’s All Appropriate Inquiries Rule and the investigation and remediation of contaminated properties.

Before becoming an attorney, Matt spent several years as a hydrogeologist for a global environmental engineering and consulting firm. That experience included planning and implementing environmental investigations, assessing risks and identifying cost-effective remedies.
