36 residential wells in Hartford have tested positive for PFAS. The Van Buren Cass District Health Department announced the results of tests on 59 wells this week. The tests were conducted by the Michigan Department of Environment, Great Lakes, and Energy after high PFAS levels were found at former the Du-Wel Metal Products site in Hartford earlier this month. The U.S. Environmental Protection Agency’s Lifetime Health Advisory level for PFAS is 70 parts per trillion, and of the 59 residential wells tested this month in Hartford, 11 exceeded that level. 25 showed PFAS below the 70 parts per trillion mark. 23 of the residential wells showed no PFAS. The Van Buren Cass District Health Department and the Michigan Department of Health and Human Services have contacted residents whose wells were sampled, and filters have been provided to residents whose well water had any amount of PFAS. Also, the water station at the Hartford Fire Department will continue to distribute water to the affected well owners in the study area until their filters are installed. The Michigan Department of Environment, Great Lakes, and Energy is working with the local health department to expand the testing area. Affected residents will be contacted. The health department says the municipal water system in Hartford has been tested for the chemical, and it came back clear.
