Well water in Sabattus, Maine
In Sabattus, 25% of 142 private wells tested had arsenic above the Maine guideline (10 ug/L), according to Maine CDC.
163 private wells tested in state summaries; 34 individual samples from 34 wells, 1976 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, 12% of 34 PFOS results in Sabattus were above the EPA limit of 4 ng/L. In that targeted sampling, 3% of 34 PFOA results in Sabattus were above the EPA limit of 4 ng/L.
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 Sabattus. 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.
| Contaminant | Samples | Detected | Above limit | Median | Highest | Limit | |
|---|---|---|---|---|---|---|---|
| PFOS 2024 to 2025 | 34 | 41% | 12% | 0 | 4.7 | 4 ng/L EPA limit | |
| PFOA 2024 to 2025 | 34 | 53% | 3% | 0.27 | 4.35 | 4 ng/L EPA limit | |
| PFHxS 2024 to 2025 | 34 | 26% | 0% | 0 | 2.82 | 10 ng/L EPA limit | |
| PFNA 2024 to 2025 | 34 | 3% | 0% | 0 | 0.346 | 10 ng/L EPA limit |

What this means
Among homeowners in Sabattus who sent a sample to the state lab, the health-based limits most often exceeded were arsenic (25% of 142 wells), uranium (18% of 119 wells), and fluoride (4% of 163 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 Sabattus
485 domestic wells in Sabattus are on record with the state since 1970. 94% are drilled into bedrock, and the typical well is 300 feet deep (one in ten goes past 520 feet).
In a typical Sabattus well, bedrock starts about 12 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 Sabattus
Maine DEP records 1 leaking underground storage tank site and 1 unlined landfill in Sabattus, 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.
- 1
- leaking underground storage tank siteGasoline 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.
