  • Defended a manufacturer in federal and state cost recovery actions, as well as in administrative actions brought by the State and Regional Water Quality Control Board, related to groundwater contamination allegedly caused by the company’s former operations in the area. 
  • Defended an agricultural corporation in litigation involving thousands of plaintiffs from multiple countries who alleged personal injuries as a result of alleged exposures to a chemical while working for the company.
  • Defended a manufacturer in an action involving claims for public and private nuisance based on the allegation that the company’s former operations caused soil and groundwater contamination.
