Vorys proudly represents our clients in courts and administrative agencies in both civil and criminal environmental proceedings across the nation.  Our attorneys defend clients in actions involving personal injury, property damage and cost recovery arising from alleged exposure to hazardous, radioactive, and/or toxic substances from Superfund sites, landfills, manufacturing plants and governmental facilities.  Often, such actions are brought as class actions, and our firm has extensive experience in addressing the unique procedural, factual, and legal issues that arise in putative class action cases. 

We also defend clients in cases involving claims of chemical spills and releases, air emissions, groundwater contamination, toxic mold, workplace exposures, and construction and excavation discoveries.  Our lawyers address the nuisance, trespass, emotional distress, and other common law claims that typically are asserted in such cases, as well as the federal and state laws that may be invoked.  We also defend against suits (including citizen actions) brought under state law, the Resource Conservation and Recovery Act (RCRA), Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), the Clean Water Act, the Clean Air Act, Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), and the Superfund Amendments and Reauthorization Act (SARA), and other federal and state statutes.  We also regularly assist and counsel our clients during enforcement investigations.

Key Areas of Focus

Enforcement and Criminal Defense

Regulators are becoming more aggressive in seeking and obtaining significant penalties in civil, criminal and administrative environmental enforcement actions.  Our attorneys have substantial experience both in defending civil and criminal environmental cases in state and federal courts, as well as before administrative review and appeal boards.  

In addition, we assist and counsel our clients during enforcement investigations and actions in cases involving air, water, solid waste, hazardous waste, underground storage tanks, wetlands and other issues.  Our attorneys provide guidance to clients on managing environmental misconduct by employees, responding to search warrants and civil subpoenas, and establishing and maintaining prudent recordkeeping practices.

PFAS Litigation

Per- and poly- fluorinated alkyl substances (PFAS) are omnipresent, newsworthy, and front-and-center for federal and state environmental lawmakers.  PFAS-specific regulations are evolving, triggering new business risks for most organizations.  More immediately, private litigation continues to grow and has been occurring even without PFAS-specific regulations.  Some states are also taking action in the absence of federal regulations.    

Vorys has been involved with PFAS litigation since its early inception and has a wealth of experience in assisting companies with PFAS-related investigations, regulatory enforcement and private litigation, as well as to stay current on expected litigation trends and provide best practices for managing risks.


The Vorys environmental team represents clients in all aspects of the Superfund/CERCLA liability process, including negotiation of administrative orders and consent decrees, defense of cost recovery actions, participation in multi-party cost recovery actions, and defense of enforcement actions brought by the United States or individual states.  We litigate matters involving liability, cost allocation, and indemnity issues.  Our attorneys have served on steering and coordinating committees in Superfund cases across the United States.  We have also brought and defended private recovery actions and contribution claims under CERCLA, tort and contract law that seek to secure reimbursement for costs incurred in remediating historic conditions.  We negotiate remedies for sites with contaminated waterway sediments and have secured alternative funding for the responsible parties under the mixed funding provisions of the Great Lakes Legacy Act and the Water Resources Development Act.

Crisis Management

The Vorys crisis management team is regularly called upon to help navigate our clients’ most difficult situations.  We understand that each crisis is unique and each one requires a variety of skill sets.  For these reasons, our team combines the experience of Vorys attorneys with the skills of on-staff strategic communication professionals.  When necessary, the team also calls upon our government relations advisors.
