Abstract

This report delineates and describes the geohydrology and susceptibility of major aquifers to contamination in Coffee, Dale, Henry, Houston, and Geneva Counties, Alabama. The major aquifers are the Upper Floridan, Lisbon, Nanafalia-Clayton, and Providence-Ripley aquifers. Estimated groundwater withdrawals for public water supplies are about 42 million gal/day. Maximum withdrawals for irrigation are 15 to 20 million gal/day. Withdrawals for self-supplied industrial and domestic uses are estimated to be 3 and 2.5 million gal/day, respectively. Long-term withdrawals of water from the Nanafalia-Clayton aquifer have resulted in significant declines in the potentiometric surface in Coffee, Dale, and Houston Counties. Significant declines in the potentiometric surfaces of the other major aquifers are not apparent. Recharge areas for all major aquifers are susceptible to contamination, but the probability of contamination of the Lisbon, Nanafalia-Clayton, and Providence-Ripley aquifers is low because the recharge areas are remote from areas of withdrawal. The recharge area for the Floridan aquifer, which consists largely of flat, sandy farmland , coincides with the area of use. This area is highly susceptible to contamination from insecticides and herbicides. (USGS)
