Our environmental attorneys handle the full scope of federal and state regulatory, compliance, and litigation matters. We specialize in anticipating risk, interpreting complex scientific evidence, and providing strategic counsel that protects both business and reputation.

Unlike many firms that offer separate environmental lawyers depending on the issue, our attorneys represent clients across every major environmental law — including CERCLA, RCRA, TSCA, the Clean Air Act, Clean Water Act, Proposition 65, and many others — ensuring continuity, clarity, and a holistic approach in every engagement.

Representative Work

Overturning Massachusetts DEP Fines

A manufacturing client faced penalties after a fire caused chemical runoff on its property. CMBG³’s investigation and expert soil analysis proved the pollution was contained onsite. The DEP dismissed all charges, saving the client thousands in fines and protecting its reputation.
PFAS Class Action Defense

Our client was a Fortune 500 company in the recyclability sector brought into one of New England’s largest PFAS class action lawsuits related to the manner in which it (and other companies) disposed of its waste byproduct at a composting facility. Plaintiff’s counsel brought novel RICO and triple damages claims against our client, which we aggressively defended at the Motion to Dismiss stage. The federal court ruled in favor of our client, saving our client from potential punitive damages claims.
