Field notes
The lookup is described as combining EPA UCMR 5 PFAS occurrence data, Safe Drinking Water Information System records, and water-system service boundaries, with address location handled by the US Census geocoder. The page says a ZIP code gives a less exact result than a full address, and cautions that utility records do not capture lead from a home's plumbing. For private wells, it recommends lab testing first.
