New storm sewer lines to curb PFAS leaking into the Flint River

A pair of storm sewers are being rerouted around Flint’s former Buick City site to try and keep PFAS out of the Flint River.

“We have on the site some storm water lines, old ones, that when they’re below the groundwater table, contaminated groundwater can leak into those storm sewers and migrate to the river,” says Grant Trigger. He's the cleanup manager for the former General Motors properties in Michigan. 

Trigger says they’ll spend the next three to four months replacing more than 3,600 feet of storm sewer lines.

Trigger says the old storm sewers will be capped to prevent the spread of PFAS.

Mumbai-based automaker Mahindra has expressed interest in redeveloping the former Buick City site.    

Mahindra and the RACER trust, which oversees the former GM properties, executed a letter of intent last August.
