What this means
Among homeowners in Pittston who sent a sample to the state lab, the health-based limits most often exceeded were fluoride (3% of 185 wells), arsenic (2% of 167 wells), and uranium (<1% of 162 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 Pittston
173 domestic wells in Pittston 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 500 feet).
In a typical Pittston well, bedrock starts about 18 feet down, the median yield is 5 gallons per minute, 32% 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 Pittston
Maine DEP records 2 leaking underground storage tank sites and 1 unlined landfill in Pittston, 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.
