Illinois EPA completes statewide sampling for PFAS in drinking water

By: Joe Jungmann

 
SPRINGFIELD – Illinois Environmental Protection Agency has announced the completion of a statewide sampling to investigate the prevalence of PFAS in drinking water in communities across the state. The Illinois EPA began the investigation in the fall of 2020 and completed sampling for 18 PFAS compounds in early 2022. PFAS chemicals are human-made and do not occur naturally in the environment.
Illinois PFAS detections were found to be similar to other Midwest states. Of the 1,017 CWSs sampled, 126 had confirmed PFAS detections, including one well in LaSalle. The data is available on an interactive website hosted by the Illinois EPA.

Due to their persistence and mobility, PFAS chemicals have been found widely in the environment, including in unpopulated areas. U.S. EPA established a federal Health Advisory for PFAS of 70 parts-per-trillion in 2016 but has taken no formal action to set drinking water standards.
