Wells in Plainfield
158 domestic wells in Plainfield are on record with the state since 1988. 99% are drilled into bedrock, and the typical well is 260 feet deep (one in ten goes past 460 feet).
In a typical Plainfield well, bedrock starts about 19 feet down, the median yield is 10 gallons per minute, 17% 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 Plainfield
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.
