  • Federal environmental laws, including CERCLA and RCRA

We also assist clients with cost recovery, contribution and damages actions in state and federal courts for soil and groundwater contamination under state and federal law (including CERCLA) and assist clients with civil penalty and criminal enforcement actions under California’s Health and Safety Code and federal RCRA.

  • Development of feasibility studies 
  • Remedy negotiation and selection 
  • Consent decrees
  • Cleanup
