PFAS in public drinking water · EPA UCMR 5 testing (2023–2025) · generated June 8, 2026
The bottom line
13
public water systems tested
0

10
with no PFAS detected at all
2.84 ppt
highest reading in the county (North Baldwin Utilities)
Every public water system serving Baldwin County tested below the federal limit of 4 parts per trillion (ppt) for the two regulated forever chemicals, PFOA and PFOS. The single highest reading anywhere in the county was 2.84 ppt — about 71% of the limit. Most systems showed no PFAS at all.

Every system, with its readings
Worst-sampling-point running annual average, in ppt. “ND” means non-detect. The limit is 4 ppt for PFOA and for PFOS.
Maps like EWG's plot several things at once — drinking water below the proposed limit, military sites, and other known sites — so a county can look covered in dots while every drinking-water system in it is actually under the limit. That is the case for Baldwin County.
The two genuinely over-the-limit systems near Baldwin County are not in it:
Saraland Water Service (PFOS ~10.7 ppt) is in Mobile County, across the bay.
Emerald Coast Utilities (ECUA) (PFOS ~24 ppt, with very high short-chain PFAS) is in Pensacola, Florida.
What this means
PFOA and PFOS are the two PFAS the U.S. EPA limits in drinking water, at 4 ppt each, measured as a running annual average at each entry point. A handful of Baldwin systems show low, detectable levels (Fairhope, North Baldwin, Belforest) — real, but well under the limit. The rest show none.
One honest caveat: these are the results from EPA's 2023–2025 testing. PFAS levels can change over time, and the limit does not take full legal effect until 2031. Your utility publishes an annual “Consumer Confidence Report” worth a glance each year. But based on the federal testing, Baldwin County’s drinking water is within the federal standard.
