Groundwater withdrawal coefficients and subtotals by water-use type, aquifer, and county, 1995–2010

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2020-08-12T00:00:00Z
Values represent withdrawal coefficients and subtotals of groundwater withdrawals coming from the surficial aquifer system, intermediate aquifer system, Floridan aquifer system, or other unnamed or unknown aquifers for given years in the period 1995–2010 in the southeastern United States. Withdrawal coefficients represent the proportion of total groundwater withdrawals coming from each aquifer for a given county, year, and national water use code. Coefficients for each county and water-use category were back-calculated from data published in Marella and Berndt, 2005, Water withdrawals and trends from the Floridan aquifer system in the southeastern United States, 1950–2000: U.S. Geological Survey Circular 1278, 20 p. and from unpublished data from the U.S. Geological Survey South Atlantic Water Science Center (Georgia District).
