What Alabama offers well owners

Here's what we know about radon and PFAS in Elmore County.

Elmore County is in the EPA's middle radon zone. An indoor air test is cheap and tells you whether to look at your water. Radon guide

Between 2023 and 2025 the EPA had 9 town water systems in Elmore County test for PFAS. 7 of them had at least one test above 4 ng/L, the new EPA limit for PFOA and PFOS. The highest single result was 29 ng/L of PFOS. No well in Elmore County has public PFAS results, so the town systems are the best clue to what's in the groundwater nearby. PFAS guide
