New Hampshire Groundwater and Water Well Statistics
Few states can accurately or confidentially determine how many residential wells are in place. For each region, the American Housing Survey by the U.S. Census provides regional data.
New Hampshire is found in the Northeast, along with these other states: Maine, Vermont, New Hampshire, Massachusetts, Connecticut, Rhode Island, New York, New Jersey, and Pennsylvania.
The last American Housing Survey Census indicates this region had 3,210,0002 households served by residential wells, with an average of 2.473 persons per household. The USGS estimates the population of self-supplied water supply users in New Hampshire to be 497,000, with 100% of their water supply from groundwater.
