Baldwin County, the fastest growing county in Alabama in 1995, is 100-percent dependent on ground water for public water supply. Ground-water withdrawals in Baldwin County were estimated to be about 7 million gallons per day in 1996, 12 million gallons per day in 1980, and 30 gallons per day in 1990. The effects of future increases in ground-water withdrawals, to supply the needs of the growing county population, cannot be assessed without defining baseline conditions. To address the future of ground-water development, the Baldwin County Commission requested the USGS to perform a study of the ground-water resources of Baldwin County.
