Well water in St. Albans, Maine

In St. Albans, 16% of 45 private wells tested had arsenic above the Maine guideline (10 ug/L), according to Maine CDC.

51 private wells tested in state summaries; 22 individual samples from 22 wells, 2021 to 2025. Data refreshed September 3, 2026.

Maine DEP samples private wells near fields where sludge or septage was spread and near other known PFAS sources, and resamples detections. PFAS shares describe wells that were tested for a reason, not every well in the area. In that targeted sampling, 5% of 22 PFOA results in St. Albans were above the EPA limit of 4 ng/L. In that targeted sampling, 5% of 22 PFNA results in St. Albans were above the EPA limit of 10 ng/L.

What this means

Among homeowners in St. Albans who sent a sample to the state lab, the health-based limits most often exceeded were arsenic (16% of 45 wells). These are ordinary wells tested by their owners, so the shares are the best available picture of a typical well here, with one caveat: people test more often when they suspect a problem.

Wells in St. Albans

192 domestic wells in St. Albans are on record with the state since 1971. 100% are drilled into bedrock, and the typical well is 240 feet deep (one in ten goes past 400 feet).

In a typical St. Albans well, bedrock starts about 15 feet down, the median yield is 6 gallons per minute, 24% of wells yield under 3 gallons per minute and usually need a storage tank.

Bedrock wells are where arsenic, uranium and radon come from: the water sits in fractures in granite and metamorphic rock and picks up whatever the rock carries. That is why testing for those three matters more here than in a dug or gravel well.

Contamination sources on record in St. Albans

Maine DEP records 2 leaking underground storage tank sites and 1 unlined landfill in St. Albans, among 4 regulated sites in total. Groundwater does not follow property lines, so a well within a few hundred feet of one of these is worth testing for what that site could release.

Shares are against Maine's guideline for each analyte (arsenic 10 ug/L, uranium 30 ug/L, fluoride 2 mg/L, manganese 0.3 mg/L, nitrate 10 mg/L, nitrite 1 mg/L). Towns with too few tests are suppressed (NR). Only the share above the guideline and wells tested are published; no medians. Retrieved September 3, 2026.
