In 1946 and 1947, the Navy towed the six most contaminated of its Bikini Atoll target ships — the carrier Independence and two submarines among them — to Hunters Point, in San Francisco, and by 1948 the yard had handled seventy-nine vessels from the tests. Cleaning the radioactivity off those hulls contaminated the shipyard's own ground in the process, and beginning in 2003 the Navy hired the engineering firm Tetra Tech EC to reverse that transfer: test and remediate the site so the city could finally build on it. Two of the firm's field supervisors later admitted in federal court what their testing actually looked like. Justin Hubbard substituted five-gallon buckets of clean soil for the potentially contaminated soil his crews were supposed to be sampling, then filled out chain-of-custody paperwork as though nothing had moved. Stephen Rolfe told his crews to do the same, by his own count, roughly twenty times.
The fraud was not confined to two men with buckets. Federal prosecutors would later allege that across fifteen Navy contracts worth a combined $262 million, Tetra Tech's technicians also manipulated the shipyard's radiological database itself, doctoring records so that scans taken at different locations appeared to have been performed by the same technician at the same time. Hubbard and Rolfe pleaded guilty and were sentenced to eight months in federal prison in 2018. But the company's exposure reached that far only because seven of its own former employees and contractors had already done something the fraud was counting on nobody doing: they sued it.
Their complaint, filed in 2013, invoked one of the oldest fraud-fighting devices in American law — the qui tam provision of the False Claims Act, which lets a private citizen sue on the government's behalf and keep a share of whatever the case recovers. On August 13, 2026, U.S. District Judge James Donato approved the resulting $57 million False Claims Act settlement, calling it fair, adequate, and reasonable; Tetra Tech had already agreed to pay $40 million more under federal environmental law in a separate Superfund settlement entered in July 2025. Close to $12 million of the False Claims Act money goes to the seven whistleblowers. Assistant Attorney General Brett Shumate put the outcome in the flattest possible terms: companies that contract with the government are expected to do business honestly and fairly.
The mechanism that produced that outcome is 163 years old. Abraham Lincoln signed the False Claims Act in 1863 to stop Civil War contractors who were shipping the Union Army sawdust packed as gunpowder, blind horses sold as cavalry mounts, and boots that fell apart in the field. Its sponsor, Senator Jacob Howard, never pretended the qui tam bounty was elegant. He told the Senate he had based those sections of the bill on the old-fashioned idea of holding out a temptation, and setting a rogue to catch a rogue, which was the safest and most expeditious way he had ever discovered of bringing rogues to justice. He was not counting on anyone's conscience. He was betting that someone inside a fraud would tell the truth once telling it paid better than staying quiet.
That bet is still the load-bearing one. An organization capable of faking a chain-of-custody form is rarely capable of confessing to one on its own; the incentive has to come from outside, or from someone still inside willing to become an outsider. The soil under a city slated for twelve thousand new homes did not care what any spreadsheet said about it. What made the difference was a law built for a battlefield, still doing the same job a century and a half later: making it worth somebody's while to say so.
