US EPA Approves Merit Laboratories for UCMR 5 PFAS Testing

US EPA Approves Merit Laboratories for UCMR 5 PFAS Testing

The U.S. EPA officially approved Merit Laboratories to perform analytical laboratory testing for PFAS compounds as part of the fifth Unregulated Contaminant Monitoring Rule (UMCR5). As part of UCMR5, Merit Laboratories is approved for analytical methods EPA 533 and EPA 537.1. UCMR 5 includes all 29 PFAS compounds that are within the scope of EPA Methods 533 and 537.1.

EPA Finalizes the Fifth Unregulated Contaminant Monitoring Rule (UCMR)

EPA Finalizes the Fifth Unregulated Contaminant Monitoring Rule (UCMR)

The U.S. EPA has published the Fifth Unregulated Contaminant Monitoring Rule (UCMR 5). UCMR 5 requires sample collection for 30 chemical contaminants between 2023 and 2025 using analytical methods developed by EPA and consensus organizations. This action provides EPA and other interested parties with scientifically valid data on the national presence of these contaminants in drinking water. PFAS are included in the UCMR.

State Infrastructure Needs Prioritize Clean Water

State Infrastructure Needs Prioritize Clean Water

Years of underinvestment in Michigan’s infrastructure, including roads, bridges, dams, schools, transit, water and sewer systems, railways and energy systems, have left the state in a precarious position, according to the American Society of Civil Engineers (ASCE) 2018 Report Card for Michigan's Infrastructure and the 21st Century Infrastructure Commission.

Michigan Moving Forward with Draft MCLs for PFAS in Drinking Water

 Michigan Moving Forward with Draft MCLs for PFAS in Drinking Water

The Michigan PFAS Action Response Team (MPART) formally recommended to move forward with establishing draft maximum contaminant levels (MCLs) for PFAS compounds in drinking water. The recommendation was made by unanimous vote by MPART’s board on September 27, 2019 in Lansing. The MPART board is recommending the following health-based MCLs for seven PFAS compounds.

Michigan PFAS Drinking Water Rules Moving Forward

Michigan PFAS Drinking Water Rules Moving Forward

Moving Michigan forward on PFAS drinking water regulations, the Science Advisory Workgroup recently provided its health-based values to the Michigan PFAS Action Response Team (MPART). These PFAS health-based values will be used by the State of Michigan to develop regulatory drinking water standards.

EPA Issues Guidance for PFAS Groundwater Contamination with Draft Interim Recommendations

EPA Issues Guidance for PFAS Groundwater Contamination with Draft Interim Recommendations

The U.S. EPA has released draft recommendations for addressing groundwater contaminated with PFAS. The draft guidance specifically addresses perfluoroctanoic acid (PFOA) and perfluoroctane sulfonate (PFOS) at contaminated sites falling under federal cleanup programs. 

Michigan Sets New PFAS Health Screening Levels for Drinking Water

Michigan Sets New PFAS Health Screening Levels for Drinking Water

The State of Michigan has lowered the drinking water health screening levels for PFAS. These new levels replace the federal advisory guidelines of a combined 70 ppt for PFOA and PFOS that the state had been using since January 2018.

Michigan to Establish PFAS Drinking Water MCLs

Michigan to Establish PFAS Drinking Water MCLs

The MDEQ has been directed by the governor to begin the process of creating PFAS drinking water standards.  The MDEQ will file a Request for Rulemaking to establish maximum contaminant levels (MCLs). As part of the  governor’s direction, the Michigan PFAS Action Response Team (MPART) will form a science advisory workgroup to review health-based drinking water standards to support the rulemaking process and make recommendations by July 1.
