Abstract

Transmissivity and storativity data for the clastic sediments of the northern Coastal Plain of eastern Alabama, Georgia, and western South Carolina were compiled and evaluated. Transmissivity values ranged from less than 100 to about 35,000 ft sq/day; storativity ranged from about 0.00002 to 0.0002. Data for lower Tertiary sediments represented by the Clayton and Tallahatta Formations and equivalent Midwayan and Claibornian sediments are listed for 17 sites. Transmissivity values of these sediments range from about 500 to 10,000 ft sq/day. Transmissivity values for the Cretaceous Providence Sand and Cusseta Sand and equivalent Navarroan-Tayloran sediments are listed for 10 sites and range from about 500 to 34,000 ft sq/day. Transmissivity values for the Blufftown and Eutaw Formations and equivalent Cretaceous Tayloran-Austinian sediments are listed for 16 sites and range from about 3000 to 35,000 ft sq/day. Transmissivity of the Cretaceous Tuscaloosa Formation and equivalent Eaglefordian sediments is listed for 5 sites and ranges from about 30 to 500 ft sq/day. Estimates of transmissivity based on well specific capacity were computed by using the modified nonequilibrium formula and linear regression analysis. The regression analysis was based on log-transformed paired transmissivity and specific-capacity data at 48 pumping wells. The regression model provided better estimates of transmissivity than the modified nonequilibrium formula. (Author 's abstract)
