Indiana 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.
Indiana is found in the Midwest, along with these other states: Ohio, Michigan, Indiana, Illinois, Wisconsin, Minnesota, North Dakota, South Dakota, Iowa, Nebraska, Kansas, and Missouri.
The last American Housing Survey Census indicates this region had 3,990,0002 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 Indiana to be 1,680,000, all of which were groundwater supplied.
