Well water in Rangeley, Maine

In Rangeley, 24% of 71 private wells tested had arsenic above the Maine guideline (10 ug/L), according to Maine CDC.

71 private wells tested in state summaries; 11 individual samples from 6 wells, 1979 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.

What homeowner tests found

Maine Tracking Network private well summaries: private wells tested and reported to the state. Shares are against the level the state applies to each contaminant, named in the last column; several are stricter than EPA.

What individual samples found

Each row summarizes every public sample for that contaminant inside Rangeley. Above limit means above the EPA maximum contaminant level; where EPA has no enforceable limit, the row shows a health guideline or nuisance level instead.

What this means

Among homeowners in Rangeley who sent a sample to the state lab, the health-based limits most often exceeded were arsenic (24% of 71 wells), fluoride (5% of 60 wells), and uranium (2% of 59 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 Rangeley

366 domestic wells in Rangeley are on record with the state since 1985. 99% are drilled into bedrock, and the typical well is 320 feet deep (one in ten goes past 500 feet).

In a typical Rangeley well, bedrock starts about 18 feet down, the median yield is 4.75 gallons per minute, 31% 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 Rangeley

Maine DEP records 4 leaking underground storage tank sites and 1 unlined landfill in Rangeley, among 10 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.
