The Latest News on Scientific and Regulatory Updates from Merit Laboratories
In this episode of sh(e)=mc2 we meet Abigail Hendershott of the Michigan Department of Environment, Great Lakes, and Energy (EGLE). Abigail leads the team tasked with cleaning-up Michigan’s largest PFAS site as Executive Director of MPART. Abigail shares her experience in leadership and the power of knowing your strengths and the importance of creating a team of who is not only skilled, but also happy.
The State of Michigan formally adopted a strict set of requirements regulating PFAS in drinking water. The Michigan EGLE announced the adoption of the new maximum contaminant levels (MCLs), which will go into effect on August 3, 2020. The establishment of enforceable MCLs for PFAS compounds will require compliance with the Safe Drinking Water Act (SDWA). Now they are adopted, the PFAS drinking water MCLs replace the current groundwater cleanup standard of 70 ppt for PFOA and PFOS.
In a continuing trend, another 19 sites with PFAS contamination have been added to the latest list of Michigan sites. The newest Michigan EGLE PFAS Map Tracker shows that the number of confirmed PFAS contaminated sites has grown to 93, up from 74 in December 2019 and 52 a year ago. The latest list of PFAS contamination includes sites spread across Michigan, throughout both the lower and upper peninsulas, in rural, suburban, and urban areas The EGLE also provides a PFAS map viewer, which provides information on the site name, location and address, description of the site, and a link to site-specific background, data, PFAS contaminants, site history, and recent activities.
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.
As the nation’s PFAS contamination problem continues to grow, a report recently released by the Environmental Working Group states that PFAS manufacturers have known about the risks associated with these chemicals for more than 60 years. The report documents studies and internal memos with a timeline that begins in 1950. PFAS manufacturers 3M and DuPont are the focus of the report.
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.
The congressional bill recently introduced that would require the U.S. Geologic Survey to monitor for PFAS received a hearing on June 13th. The PFAS Detection Act, introduced in March, authorizes the U.S. Geologic Survey and the U.S. EPA to coordinate and develop PFAS testing standards. The bill requires that the USGS monitor for PFAS nationwide in water through a five-year, $45-million program.
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.
