Well water in Livermore, Maine
In Livermore, 4% of 53 private wells tested had uranium above the Maine guideline (30 ug/L), according to Maine CDC.
91 private wells tested in state summaries; 9 individual samples from 5 wells, 1979 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.
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 this means
Among homeowners in Livermore who sent a sample to the state lab, the health-based limits most often exceeded were uranium (4% of 53 wells) and fluoride (1% of 91 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 Livermore
359 domestic wells in Livermore are on record with the state since 1970. 99% are drilled into bedrock, and the typical well is 280 feet deep (one in ten goes past 460 feet).
In a typical Livermore well, bedrock starts about 24 feet down, the median yield is 5 gallons per minute, 29% 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 Livermore
Maine DEP records 2 leaking underground storage tank sites, 1 unlined landfill, and 1 hazardous waste site in Livermore, among 6 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.
- 1
- unlined landfillOlder unlined landfills are a leading source of PFAS, VOCs and metals in nearby wells.
- 1
- hazardous waste siteSolvents, degreasers and metals from industrial sites can travel far in fractured bedrock.

Common questions
How deep are wells in Livermore?
The typical domestic well in Livermore is 280 feet deep, based on 359 wells reported to the state since 1970. One in ten is deeper than 460 feet. 99% are drilled into bedrock.
Is there arsenic in well water in Livermore?
Arsenic was detected in 67% of 6 public well samples in Livermore, and 0% were above the EPA limit of 10 ug/L. Arsenic has no taste or smell; a lab test is the only way to know your level.
How high is radon in well water in Livermore?
The median radon level across 2 public samples in Livermore was 935 pCi/L, with a high of 950 pCi/L. New Hampshire recommends treatment above 2,000 pCi/L.
How often should I test a private well in Livermore?
Test for bacteria and nitrate every year. Test once for arsenic, uranium, radon, fluoride, manganese and PFAS, then again every three to five years or after any change in taste, color, or plumbing.

Non-detects count as samples and are treated as zero when computing medians. Exactly at the limit counts as not above it. A sample belongs to the town containing the well's reported coordinates.
