| Abstract: | Colquitt County, Georgia, is predominantly agricultural, but has some light industry. Anticipated growth in industrial activity and an increase in irrigation will impose some additional strains on the water supply. Streams in the county generally are undependable as sources of water, so wells are the principal source for domestic, municipal, and industrial uses. The abundant supply of ground water is generally of good quality. The most productive sources are limestone beds of Eocene, Oligocene, and Miocene age that make up the principal artesian aquifer. These beds can yield in excess of 1,000 gal/min of water to wells. The ability to transmit water to wells is modified by a structural, or a paleogeographic feature called the Suwannee strait, which extends from near the southwest corner through the northeast part of Colquitt County. In this strait limestone beds seem to be partly replaced by marl, which greatly impairs their transmissivity. Aquifer tests suggest that the transmissivity of the principal artesian aquifer is as much as 10 times as great southeast of the strait as it is to the northwest. A shallow depression in the potentiometric surface of the principal artesian aquifer near the center of heaviest pumping at Moultrie seems to parallel the hypothesized northeast-trending Ochlockonee fault, and may reflect enhanced anisotropic transmissivity.
