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.
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.
As an industry leader in PFAS testing, Merit Laboratories is pleased to announce that it has purchased additional PFAS analytical testing instrumentation. The instrumentation addition will increase Merit’s PFAS testing sample capacity. Merit added the Agilent 6495B Triple Quadrupole LC/MS to its instrumentation roster because of recent technical advances.
The Michigan Department of Environmental Quality (MDEQ) is deploying drones to fly over Lake Margrethe to search for cold water springs that could be carrying PFAS contamination into the lake near Camp Grayling. The MDEQ believes this is the first-ever usage of drones to search for PFAS contamination.
While testing for PFAS in water sample matrices captures most of the attention, the analysis of soil for PFAS is growing in importance. Environmental scientists are working hard to identify and investigate the presence of PFAS contamination in soil. Soil site investigation efforts are increasing in importance as regulatory agencies and communities are looking to identify the sources of PFAS contamination.
In May, we shared with you information about a national PFAS contamination site tracker being maintained by Northeastern University’s Social Science Environmental Health Institute (SSEHRI). At the time, there were 17 sites in Michigan on the SSEHRI PFAS Contamination Site Tracker list. In just four months, the number has increased to now include 28 Michigan sites with PFAS contamination.
The State of Michigan has started posting PFAS testing results from the statewide drinking water initiative for schools using well water. The state has created a database of PFAS results for public review. The school drinking water results are posted here. The second part of the statewide initiative involves PFAS testing of public water supplies and these results are posted here.
