Report from EWG shows that Chemical Manufacturers Knew of the Risks Associated with PFAS more than 60 years ago

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.

State of Michigan Releases First PFAS Sampling of Drinking Water Supplies Report

State of Michigan Releases First PFAS Sampling of Drinking Water Supplies Report

The Michigan Department of Environment Great Lakes & Energy (EGLE) has released its report detailing a massive state-wide PFAS drinking water sampling program that began in April 2018. The report, PFAS Sampling of Drinking Water Supplies, presents findings of EGLE’s sampling efforts from more than 1,700 facilities.

Wisconsin's Largest PFAS Clean-up Program on Tap

Wisconsin's Largest PFAS Clean-up Program on Tap

Groundwater contaminated with PFAS in Marinette, Wisconsin is slated for environmental remediation. Marinette, a small town located in northeastern Wisconsin, is home to the headquarters of the Tyco Fire Products unit of Johnson Controls, Inc. (JCI). According to the Wisconsin DNR, the Marinette PFAS remediation will be the most expensive PFAS cleanup in the state. Some estimates place the cleanup effort at more than $140-million.

Michigan EGLE PFAS Map Tracker Confirms Growing Number of PFAS Contaminated Sites

Michigan EGLE PFAS Map Tracker Confirms Growing Number of PFAS Contaminated Sites

Residents can now track the locations of PFAS sites in Michigan, which continues to grow. According to the most recent update to the PFAS Map Tracker from the Michigan EGLE (formerly MDEQ), the number of confirmed PFAS contaminated sites has grown to 52. The PFAS site map shows sites spread across Michigan.  

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 The draft guidance specifically addresses perfluoroctanoic acid (PFOA) and perfluoroctane sulfonate (PFOS) at contaminated sites falling under federal cleanup programs. 

The Number of PFAS Sites in Michigan Grows

The Number of PFAS Sites in Michigan Grows

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 PFAS Laboratory

Merit Laboratories is Michigan’s PFAS Laboratory

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.

Just the Facts!   PFAS Fact Sheets Published by ITRC

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

Michigan’s PFAS Industrial Pretreatment Program Initiative on the Fast Track

Michigan’s PFAS Industrial Pretreatment Program Initiative on the Fast Track

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:
