Abstract

The U.S. Army Corps of Engineers ' plan to control the natural chloride pollution in Wichita River basin includes construction of Truscott Brine Lake on a tributary of North Wichita River. In connection with the proposed brine lake, the U.S. Geological Survey was requested to define the existing ground-water conditions in the shallow freshwater system of the project area and to project the postconstruction effects of the proposed lake on the freshwater aquifer. The freshwater aquifer in the project area is a shallow water-table system with relatively freshwater that contains approximately 500-5,000 milligrams per liter of dissolved solids and consists of Permian rocks with very small values of hydraulic conductivity. It overlies a brine system that is even less permeable. Two-dimensional mathematical computer models were developed for aquifer simulation of steady-state conditions in a freshwater system and transient conditions in a brine-freshwater system where density effects of the brine are considered. Main results of the project are: (1) Water-level rises in the aquifer of 5-40 feet would be confined to areas near the proposed dam and along lake shoreline, and (2) migration of saltwater downstream from dam generally would be limited to less than 1 mile and apparently, would not reach equilibrium during the 100-year duration of the project.
