Well water in Fort Fairfield, Maine

In Fort Fairfield, 15% of 47 private wells tested had nitrate above the Maine guideline (10 mg/L), according to Maine CDC.

47 private wells tested in state summaries; 45 individual samples from 45 wells, 1986 to 2023. 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, 2% of 45 PFOA results in Fort Fairfield were above the EPA limit of 4 ng/L. In that targeted sampling, 2% of 45 PFOS results in Fort Fairfield were above the EPA limit of 4 ng/L.

What this means

Among homeowners in Fort Fairfield who sent a sample to the state lab, the health-based limits most often exceeded were nitrate (15% of 47 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 Fort Fairfield

60 domestic wells in Fort Fairfield are on record with the state since 1975. 97% are drilled into bedrock, and the typical well is 121 feet deep (one in ten goes past 252 feet).

In a typical Fort Fairfield well, bedrock starts about 9 feet down, the median yield is 10 gallons per minute, 8% 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 Fort Fairfield

Maine DEP records 3 leaking underground storage tank sites, 2 unlined landfills, and 1 hazardous waste site in Fort Fairfield, among 23 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.

leaking underground storage tank sitesGasoline and heating oil that leaked from tanks move through groundwater as benzene, MTBE and other volatile organic compounds.
