San Francisco Hunters Point land development on hold as falsification of toxics cleanup investigated

NBC Bay Area reported earlier this year that a former Tetra Tech employee said he had been told to swap potentially contaminated soil samples for clean ones, dump potentially contaminated soil into open trenches around Hunters Point, sign falsified documents submitted to the government, and tamper with computer data about radiation levels. Other former workers said they were fired in retaliation after reporting violations to regulators.

 

UC Santa Cruz researcher Dan Hirsch, part of a team preparing a report on the cleanup, said that not only had Tetra Tech falsified soil samples, the Navy has been using outdated remediation standards that allow much higher levels of toxic material than the EPA currently recommends—in some cases about 100 times higher—and radiation levels equivalent to 12 chest x-rays per year for residents.

“We found over and over again that the Navy used standards that EPA said they aren’t supposed to use,” Hirsh said.
