On August 16, the Michigan PFAS Action Response Team (MPART) published the final report from last year’s statewide sampling of community, school, childcare provider, and tribal water supplies for PFAS. Overseen by the Michigan Department of Environment, Great Lakes, and Energy, MPART sampled 1,723 public water systems statewide for 14 different PFAS compounds. As previously reported in ECOSWIRE, roughly 90 percent of these supplies showed no detection for PFAS, 7 percent detected very low levels of PFAS (below 10 parts per trillion (ppt)), and 3 percent detected PFAS levels between 10 and 70 ppt. Only two sites tested at levels exceeding U.S. EPA’s Lifetime Health Advisory of 70 ppt for PFOA and PFOS in drinking water.
MPART will continue to monitor sites at 10 ppt or higher on a quarterly basis, and will test sites with surface water sources monthly. It has also expanded the statewide PFAS survey to cover additional types of public water supplies like those serving sensitive populations or to address worker safety.
