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 Waldoboro who sent a sample to the state lab, the health-based limits most often exceeded were uranium (28% of 107 wells), arsenic (10% of 123 wells), and fluoride (2% of 176 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 Waldoboro
653 domestic wells in Waldoboro are on record with the state since 1970. 99% are drilled into bedrock, and the typical well is 240 feet deep (one in ten goes past 380 feet).
In a typical Waldoboro well, bedrock starts about 17 feet down, the median yield is 5.5 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 Waldoboro
Maine DEP records 10 leaking underground storage tank sites, 2 unlined landfills, and 3 hazardous waste sites in Waldoboro, among 23 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.
