Testing strongly recommended
private wells tested in West Gardiner had arsenic above the Maine guideline (10 ug/L), according to Maine CDC.

Compiled by Nick at Well Water Nerd from public records. How these pages are built
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.

Among homeowners in West Gardiner who sent a sample to the state lab, the health-based limits most often exceeded were arsenic (27% of 339 wells), uranium (14% of 254 wells), and fluoride (2% of 324 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 West Gardiner
269 domestic wells in West Gardiner are on record with the state since 1970. 99% are drilled into bedrock, and the typical well is 260 feet deep (one in ten goes past 457 feet).
In a typical West Gardiner well, bedrock starts about 11 feet down, the median yield is 6 gallons per minute, 26% 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 West Gardiner
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 West Gardiner
Maine DEP records 6 leaking underground storage tank sites in West Gardiner, among 8 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.
