HARTFORD — Thirty-six residential wells out of 59 tested in Hartford have some amount of per- and polyfluoroalkyl substances (PFAS) in them.

The Michigan Department of Environment, Great Lakes, and Energy (EGLE), in coordination with the Van Buren/Cass District Health Department and the Michigan Department of Health and Human Services (MDHHS), announced this week the results of the testing that took place May 10-13 near the former Du-Wel Metal Products site.

The Du-Wel plant was located at 520 Heywood St. It closed in 1992.

The results for two PFAS compounds, perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) were added together and compared to the U.S. Environmental Protection Agency’s Lifetime Health Advisory level of 70 parts per trillion (ppt).

Twenty-five drinking water wells identified PFOA and PFOS at concentrations below 70 ppt and 11 wells exceeded 70 ppt for PFOA and PFOS. Twenty-three wells did not have any PFOA or PFOS.

The agencies reported that the highest concentration of PFOA and PFOS found was 900 ppt.

The Van Buren/Cass District Health Department and MDHHS have contacted residents whose wells were sampled to communicate the results of the testing. Filters have been provided to residents whose well water had any amount of PFAS.

The water station at the Hartford Fire Department at 436 E. Main St. will continue to distribute water to the affected well owners in the study area until the filters are installed.

The city of Hartford's water was retested on May 14 and no PFAS was found.

Any resident with questions should contact the Van Buren/Cass District Health Department at 621-3143 Ext. 1311 or EGLE’s Environmental Assistance Center at 800-662-9278.

Residents with health related questions may also contact MDHHS’ MI-Toxics line at: 800-MITOXIC (1-800-648-6942). Any resident within the current study area with a water well on their property that has not been tested is encouraged to contact EGLE’s Environmental Assistance Center to arrange for their well to be sampled.
