What they found
This study found detectable PFAS in 15.4% of Indiana's public drinking water systems, with 1.9% exceeding proposed maximum contaminant levels. Statewide fish monitoring revealed substantial bioaccumulation, with PFOS comprising ~69% of the total PFAS burden.
What they studied
Researchers conducted a cross-media evaluation of PFAS occurrence, distribution, bioaccumulation, and exposure across Indiana, a U.S. state with mixed land use. They analyzed atmospheric deposition, 473 public water systems, 940 fish samples, and preliminary human serum biomonitoring.
Takeaways
The abstract focuses on findings; it does not give personal how-to steps.
About this paper
This peer-reviewed study conducted an integrated, multi-compartment assessment of PFAS at a regional scale in Indiana. It utilized targeted LC-MS/MS and electrochemical sensor approaches to detect both known and previously unmonitored PFAS compounds. Bench-scale treatment tests were also conducted.
