Environmental Litigation
Tonkon Torp attorneys understand the science and complicated legal issues involved in complex environmental litigation. Our environmental litigation team includes lawyers with advanced degrees and work experience in environmental science, which allows them to translate scientific and technical concepts to jurors, judges, arbitrators, consultants and peers.

We build collaborative trial teams that include both seasoned environmental trial lawyers and experienced regulation attorneys that handle litigation in federal and state courts throughout the region. We represent clients in lawsuits, high-profile administrative proceedings and private arbitrations. Tonkon Torp attorneys handle matters involving toxic torts and personal injuries, and help clients address insurance issues associated with environmental liabilities.

Our environmental attorneys work diligently to prevent lawsuits, but when these disputes do arise, we provide creative strategies for prevailing in litigation as quickly and cost-effectively as possible.

Our representations include:
  • The defense of criminal and civil investigations and prosecutions
  • Litigation arising from private citizen suits
  • Natural resource damage claims
  • Superfund cost recovery claims
