A major project to stop PFAS discharges in Flint has restarted and is expected to be finished sometime this fall
A project to stop per- and polyfluoroalkyl substances (PFAS) discharges in Flint, Michigan has restarted and is expected to be finished sometime this fall.
This project is the rerouting of a storm sewer line through Buick City, according to Booth Newspapers.
Revitalizing Auto Communities Environmental Response Trust, which owns the old Buick site, made the announcement in an update posted on its web site. This announcement comes four months after the sewer work was paused due to COVID-19 stay at home orders.
The project involves replacing and rerouting more than 3,600 feet of underground storm sewer lines. The goals is to stop PFAS contamination from continuing to spill into the Flint River. Currently, the river is no longer used for drinking water and accessing groundwater at Buick City for drinking or any other purposes is prohibited by the Michigan Department of Environment, Great Lakes, and Energy (EGLE).
Testing of water wells located near the Buick City property has not identified any contamination that has or could potentially contaminate any drinking water sources, according to RACER in its recent release.
Sampling crews and drilling rigs were scheduled to be on site to collect more soil and groundwater samples near Hamilton Avenue on Jul. 27. This area is a potential source area of PFAS after initial testing showed high levels of the man-made chemicals including PFOA and PFOS. One Buick City site sampled at 38,000 ppt of PFOS, which is more than 3,000 times that state rule.
“It is likely that additional rounds of sampling will be conducted later this summer, and a follow-up report reviewing possible treatment or remediation technologies will be prepared for review by EGLE in late fall,” said RACER in its recent release.
