At Last! EPA Finally Validates PFAS SW-846 Method 8327

The U.S. Environmental Protection Agency (EPA) finally validated EPA SW-846 Method 8327 for the analysis of PFAS using LC/MS/MS instrumentation for non-potable water. Sample matrices for EPA 8327 include surface water, groundwater water, and wastewater. The method evaluated 24 PFAS compounds.

U.S. Congressional Bill Introduced to Require Water Monitoring for PFAS Receives Hearing

 U.S. Congressional Bill Introduced to Require Water Monitoring for PFAS Receives Hearing

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.

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 The draft guidance specifically addresses perfluoroctanoic acid (PFOA) and perfluoroctane sulfonate (PFOS) at contaminated sites falling under federal cleanup programs.

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.

Senate Legislation Keeps PFAS on track to be Designated as Hazardous Substances under Superfund

 Senate Legislation Keeps PFAS on track to be Designated as Hazardous Substances under Superfund

The United States Senate introduced legislation that would classify PFAS chemicals as hazardous substances under the Superfund (CERLCA/SARA).  The legislation, if enacted, provides an enforcement and cost recovery tool for the U.S. EPA to track down polluters and hold them responsible for clean-up costs associated with PFAS contamination.

Michigan PFAS Advisory Report Highlights Proactive Approach to Protecting State Residents

Michigan PFAS Advisory Report Highlights Proactive Approach to Protecting State Residents

Last month, Merit Laboratories introduced you to the advisory report on the Scientific Evidence and Recommendations for Managing PFAS Contamination in Michigan. The report, authored by the Michigan PFAS Science Advisory Panel with support from state agency staff, provides a detailed look at Michigan’s PFAS contamination crisis. 

U.S. EPA Releases First-Ever PFAS Action Plan

 U.S. EPA Releases First-Ever PFAS Action Plan

The U.S. Environmental Protection Agency (EPA) released its PFAS Action Plan for addressing the Per- and Polyfluoroalkyl Substances (PFAS) challenges facing the nation. The PFAS Action Plan addresses short-term solutions for addressing PFAS and long-term strategies that will help provide the tools and technologies needed to provide clean drinking water and address PFAS prevention and contaminant control at the source.
