What this means
Among homeowners in Limington who sent a sample to the state lab, the health-based limits most often exceeded were arsenic (24% of 107 wells), uranium (11% of 88 wells), and fluoride (3% of 126 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 Limington
320 domestic wells in Limington are on record with the state since 1970. 93% are drilled into bedrock, and the typical well is 320 feet deep (one in ten goes past 510 feet).
In a typical Limington well, bedrock starts about 30 feet down, the median yield is 7 gallons per minute, 23% 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 Limington
Maine DEP records 2 leaking underground storage tank sites, 1 unlined landfill, and 1 hazardous waste site in Limington, among 5 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.

Town summaries of private well tests run by the Maine Health and Environmental Testing Laboratory, published by Maine CDC through the Maine Tracking Network. 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.
