Recent research conducted by the United States Geological Survey (“USGS”) determined that at least 45% of the tap water in the United States is projected to contain at least one type of per- and polyfluoroalkyl substances (“PFAS”). The USGS’s study assessed over 700 private and public tap water supplies in the United States, though they believe that the lack of detailed information about PFAS exposure in unregulated private wells may impact their projected estimated of PFAS-impacted tap water.

USGS’s research compared human PFAS exposures in 716 different locations, with 269 unregulated private wells, and 447 regulated public-supply tap water sources analyzed across the US from 2016–2021. The study found estimated median cumulative concentrations being similar among private wells and the public-supply. USGS has determined that the results are definitive evidence that further assessments of the health risks of PFAS as a class of contaminant, and in combination with other co-occurring contaminants (meaning other contaminants which are likely to be present alongside PFAS), are necessary.Continue Reading Recent United States Geological Survey Finds Over 45% of Tap Water Contaminated by PFAS

On May 17, 2023, the Minnesota Pollution Control Agency and the Minnesota Department of Natural Resources announced that they had reached a settlement with Douglas Corp., a chrome plater, regarding its historical use and disposal of plating solutions containing per- and polyfluoroalkyl substances (“PFAS”) as part of its plating operations.

At issue were Douglas Corp.’s
