The list continues to grow. The Michigan PFAS Action Response Team’s (MPART) list of sites where the MDEQ has confirmed detections of PFOA and PFOS in groundwater has grown by another 16 sites. The list now includes the following sites.
The number of sites with PFAS contamination in Michigan continues to grow. The MDEQ has compiled a listing of these PFAS sites along with a map that have been identified as having PFAS levels that are potentially impacting human health and the environment . The sites, which are found at locations throughout Michigan, include:
Merit Laboratories is Michigan’s environmental laboratory for PFAS analytical testing. Merit offers two analytical options for PFAS: EPA 537 and ASTM D7979. Merit Laboratories performs EPA 537 in drinking water for the list of 14 PFAS substances that are EPA-approved by the method. EPA 537 is a prescriptive Drinking Water Method for 14 PFCs. We also perform ASTM D7979, which is a method for non-drinking water matrices. Merit Laboratories can analyze for the MDEQ PFAS requested list of 24 PFAS substances using ASTM D7979.
The Interstate Regulatory Technology Council (ITRC) just published three new fact sheets on Per- and Polyfluoroalkyl Substances (PFAS) along with one updated fact sheet. The four fact sheets address important topics related to PFAS remediation technologies, sample collection, laboratory methods, environmental fate and transport, and more. These four PFAS updates from ITRC are the most current guidance available and will provide environmental professionals with detailed information on PFAS
The presence of PFAS at sites throughout Michigan have prompted the Michigan Department of Environmental Quality (MDEQ) to require Wastewater Treatment Plants (WWTP) with an Industrial Pretreatment Program (IPP) to address this emerging contaminant. In a letter to WWTPs dated February 20, 2018, the MDEQ is requiring several actions be taken to ensure that all IPPs are prohibiting discharges of PFOS and PFOA. By June 20, 2018, the MDEQ is requiring WWTPs with an IPP to complete the following:
The Michigan Department of Environmental Quality (MDEQ) announced the establishment of new drinking water criterion for perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS). The criterion, the first of its kind in Michigan for these compounds, is set at 70 parts per trillion (ppt) for the combined concentration of PFOA and PFOS for both residential and non-residential drinking water.
