Tennessee 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.
Tennessee is found in the South, along with these other states: Maryland, Delaware, Virginia, North Carolina, South Carolina, Georgia, Florida, Alabama, Mississippi, Texas, Oklahoma, Arkansas, Tennessee, and Kentucky.
The last American Housing Survey Census indicates this region had 4,360,0002 households served by residential wells, with an average of 2.553 persons per household. The USGS estimates the population of self-supplied water supply users in Tennessee to be 594,000, with 100% of their water supply from groundwater.
