In a four-page order, U.S. District Judge James Donato, a Barack Obama appointee, said the settlement between contractor Tetra Tech EC, a wholly owned subsidiary of Tetra Tech Inc., and the government is “fair, adequate, and reasonable under all the circumstances,” noting no party or person had objected. Four whistleblowers — relators Elbert Bowers, Arthur Jahr, III, Archie Jackson and Susan Andrews — initially filed the qui tam case in March 2013 on behalf of the government, accusing Tetra Tech EC of falsifying soil tests that were supposed to verify the decontamination of Hunters Point Naval Shipyard in San Francisco, a 400-acre site where more than 10,000 homes were slated to be built.
