Rhode Island 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.
Rhode Island 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 2.493 persons per household. The USGS estimates the population of self-supplied water supply users in Rhode Island to be 113,000, with 100% of their water supply from groundwater.
