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.
Florida 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 2.653 persons per household. The USGS estimates the population of self-supplied water supply users in Florida to be 2,460,000 all supplied by groundwater.
