Wells in Hodgdon

136 domestic wells in Hodgdon are on record with the state since 1988. 100% are drilled into bedrock, and the typical well is 180 feet deep (one in ten goes past 300 feet).

In a typical Hodgdon well, bedrock starts about 9 feet down, the median yield is 12 gallons per minute, 4% 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.
