Table 5: Groundwater withdrawals from the Floridan aquifer system by county, 2005

Values represent groundwater withdrawals from the Floridan aquifer system for 2005 in the southeastern United States. Withdrawals were computed by multiplying the gross groundwater withdrawals for each county by a coefficient representing the proportion of total groundwater withdrawals coming from each aquifer. 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aquifer system in the southeastern United States, 1950–2000: U.S. Geological Survey Circular 1278, 20 p. and also from unpublished data from the U.S. Geological Survey South Atlantic Water Science Center (Georgia District).
