The Bray Road Site located at 5200 Bray Road, was historically used by the City of Flint as a storage area for drinking water treatment residuals, including lime and ferric chloride. In the 1980's, the city began using it for storage of inert materials such as concrete, rock, and asphalt. In 2001, EGLE became aware that unapproved solid waste materials were being disposed of at the site and ordered the city to stop solid waste disposal activities and perform investigations to address any potential contamination. Due to this historical contamination, EGLE issued a request for PFAS sampling in January 2021.
Groundwater flow direction is east-northeast toward the CS Mott Lake reservoir, however, PFAS is not discharging to the lake at levels above health criteria. The Cornwell Drain runs along the northern boundary of the property and drains into CS Mott Lake.
For information on fish sampling in Mott Lake and other water bodies, see the MPART Eat Safe Fish Guidelines webpage.

There are four residential drinking water wells nearby, three of which have been sampled by EGLE. EGLE is working with DHHS and the local health department to determine if there are any other nearby residential wells that need to be considered for sampling. The Great Lakes Water Authority (serving the City of Flint) and Genesee County Drain Commissioner, Water Treatment Plant (serving Genesee Township) have not had detections of PFAS and continue to be safe to drink.
The City of Flint will perform additional sampling of groundwater wells and surface water to fully delineate the extent of PFAS contamination. The next sampling event is not yet scheduled but is anticipated to occur in November 2021. MDHHS will provide and install a permanent point-of-use filter to the resident with PFAS exceedances. EGLE will continue to investigate additional sources of PFAS within the Cornwell Drain. EGLE will continue efforts to obtain an access agreement to sample the one remaining residential well.

*Residential well and groundwater monitoring well results are compared to EGLE Part 201 criteria for 7 PFAS compounds effective 12/21/2020: PFOS (16 ppt), PFOA (8 ppt), PFNA (6 ppt), PFHxS (51 ppt), PFHxA (400,000 ppt), PFBS (420 ppt), and HFPO-DA (370 ppt). *Surface water samples are compared to Rule 57 non-drinking water values of 12 ppt for PFOS and 12,000 ppt for PFOA.
