Well water in North Washington UT, Maine
In North Washington UT, none of 34 tested well samples exceeded the EPA limit for nitrate, based on public data from USGS Water Quality Portal.
The strongest signal is arsenic: 7% of 29 local samples were above the limit, too few samples to carry the headline but first on the test list below.
7 private wells tested in state summaries; 290 test results across 9 contaminants from at least 20 wells, 1980 to 1986; iron has the most at 36. Data refreshed September 3, 2026.

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 North Washington UT. 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.

The same records, drawn around one point: which wells within a few miles were sampled and what they found, how deep the wells next to you were drilled, and any leaking tank or cleanup site within a mile.
Check my addressWhat this means
The contaminants most often above their limit here are arsenic (7% of 29 samples). A well next door can differ sharply from yours because bedrock fractures, well depth and plumbing all matter, so these rates describe the area, not your tap.
Iron, Manganese, and Chloride are widespread in local groundwater. They are mainly a staining and taste problem, but high manganese also carries a health advisory for infants.

Wells in North Washington UT
67 domestic wells in North Washington UT are on record with the state since 1971. 97% are drilled into bedrock, and the typical well is 218 feet deep (one in ten goes past 394 feet).
In a typical North Washington UT well, bedrock starts about 30 feet down, the median yield is 10 gallons per minute, 24% 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.
The rock under North Washington UT
Not a principal aquifer
The USGS map places this area outside any principal aquifer, which usually means wells here draw from fractured bedrock or thin local deposits rather than a large regional aquifer. Bedrock wells of that kind are where arsenic, radon and uranium turn up, and yields vary from well to well.
Classification from the USGS Principal Aquifers of the United States (national map, 2003 edition, GIS release 2015), read at the town centroid. A single well can sit in a different unit, especially near a boundary.

Contamination sources on record in North Washington UT
Maine DEP records 3 leaking underground storage tank sites and 3 unlined landfills in North Washington UT, among 12 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.
- 3
- leaking underground storage tank sitesGasoline and heating oil that leaked from tanks move through groundwater as benzene, MTBE and other volatile organic compounds.

- unlined landfillsOlder unlined landfills are a leading source of PFAS, VOCs and metals in nearby wells.
