Tetra Tech EC Inc. (Tetra Tech), a wholly-owned subsidiary of Tetra Tech, Inc., paid $57 million to resolve False Claims Act allegations that it fabricated work and falsified data the U.S. Department of the Navy relied on to determine whether the former Hunters Point Naval Shipyard (HPNS) in the San Francisco Bay was free from harmful radiation.
In a lawsuit filed in the U.S. District Court for the Northern District of California, the government alleged that, pursuant to contracts issued by the Navy between 2003 and 2014, Tetra Tech was required to investigate the soil and buildings at HPNS and to remediate any areas where radiation was excessive so that the property could be transferred to the City of San Francisco for redevelopment. The government alleged that Tetra Tech instructed field technicians to discard soil samples collected from potentially contaminated locations, replace the discarded samples with “clean” soil known to satisfy the release criteria, and to submit the replaced samples for laboratory analysis. The complaint further alleged that Tetra Tech intentionally manipulated scan results in its database that falsely represented that scans taken at different locations were conducted by the same technician at the same time. The government alleged that Tetra Tech benefited from this misconduct by receiving unearned contract award fees and avoiding obligations to perform additional remediation work, thereby decreasing its costs and increasing its profits.
“We expect companies contracting with the government to do business honestly and fairly,” said Assistant Attorney General Brett A. Shumate of the Justice Department’s Civil Division. “This settlement demonstrates the Department’s continuing commitment to hold accountable those who fail to fulfill their responsibilities in providing services to the U.S. military.”
“Over the past two decades, the federal government has dedicated significant resources to ensuring that the Hunters Point Naval Shipyard is free from harmful radiation and safe for public use. This has been a critical project for the Hunters Point community and the federal government, and it should have been just as important to the contractor that the government selected and paid to perform radiological testing and remediation at the site,” said U.S. Attorney Craig H. Missakian for the Northern District of California. “This litigation and settlement send a clear message that the government will hold contractors accountable for knowingly defrauding taxpayers by flouting their duties.”
“By falsifying work claims and manipulating critical data, Tetra Tech put its own financial interests ahead of its commitments to the Department of the Navy, potentially placing the health and safety of the American people at risk,” said Acting Special Agent in Charge Brian Merkal of the NCIS Economic Crimes Field Office. “NCIS and our federal partners remain committed to protecting the integrity of the procurement process within the Department of War.”
The settlement resolves allegations filed under the qui tam or whistleblower provision of the False Claims Act, which permits private parties to file suit on behalf of the United States for false claims and share in a portion of the government’s recovery. The Act permits the United States to intervene and take over responsibility for litigating these cases, as the United States did here. The consolidated qui tam cases are captioned United States ex rel. Jahr, et al., v. Tetra Tech EC, Inc., Case No. 13-3835 (N.D. Cal.) and were brought by Arthur R. Jahr III, Elbert G. Bowers, Susan V. Andrews, Archie R. Jackson, Anthony Smith, Donald K. Wadsworth, and Robert McLean, former employees and contractors of Tetra Tech. The relators’ share of the settlement is approximately $11,970,000.
The resolution obtained in this matter was the result of a coordinated effort between the Justice Department’s Civil Division, Commercial Litigation Branch, Civil Fraud Section, and the U.S. Attorney’s Office for the Northern District of California, with assistance from the Naval Criminal Investigative Service, Defense Criminal Investigative Service, and the Defense Contract Audit Agency. The Justice Department also expresses its appreciation for the assistance provided by the Department of Navy, the Environmental Protection Agency, and the Nuclear Regulatory Commission.
The matter was handled by Civil Division Trial Attorney Jonathan Hoerner and Assistant U.S. Attorney Savith Iyengar for the Northern District of California.
This year the Administration launched the Task Force to Eliminate Fraud and the National Fraud Enforcement Division to enhance the Administration’s war on fraud, waste, and abuse in federal programs. When unscrupulous actors exploit these programs for their own financial gain, they defraud the government, harm the people these programs are designed to aid and protect, and undermine American businesses that play by the rules. The Civil Division’s FCA enforcement plays a critical role in combatting such fraudulent schemes, recovering billions of dollars for the American taxpayers, and holding wrongdoers accountable. FCA matters will continue to be on the forefront of the battle against fraud, and the Civil Division’s FCA work will support and advance the mission of the Task Force to Eliminate Fraud and the National Fraud Enforcement Division.
The United States also recovered $40 million in a separate settlement under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), also known as Superfund, that was entered by the U.S. District Court for the Northern District of California on July 2, 2025.
The claims resolved by the settlement are allegations only and there has been no determination of liability.
