FLINT, MI — Results from new sampling for PFAS in Flint show four additional locations at the former Buick City factory are contaminated, and one residence near a second closed General Motors facility has the chemicals in its well.
"We have some … preliminary results and they’re pretty high," said Grant Trigger, Michigan cleanup manager for RACER Trust, about Buick City.
There’s no indication the contamination is reaching drinking water supplies in the city, Trigger said.
Results are still being reviewed, Trigger said, even as RACER plans a pair of community meetings in November to discuss PFAS on its sites and answer questions.
The Buick City property had been a factory site for a century before it moved into RACER’s control for cleanup and redevelopment after the GM bankruptcy.
Cleanup is ongoing, and parcels have been sold to new industrial users.
The new locations at Buick City with PFOS are: The old GM wastewater treatment plant on Stewart Avenue, at 4,800 ppt.
RACER is collecting more samples near the storm sewer, with results expected back in the first week of November.
Four additional monitoring wells will be added to the property starting this week, allowing more groundwater tests.
Homes on Stanley Road near the long-closed landfill on the property were tested for PFAS, with one reaching a combined 69 ppt for both PFOS and PFOA.
