|Mississippi Embayment Regional Ground Water (PDF) (192 pp, 13 MB) (EPA/600/R-10-130) January 2011
Increased water usage in the southeastern United States in the tri-state area of Tennessee, Mississippi and Arkansas poses a dilemma to ensuring long-term sustainability of the quantity and quality of ground-water resources that underlie the region. Demand for ground water by agriculture, municipalities and industry are presently stressing the sustainable yield of the fresh water aquifers. Instances of ground-water contamination have closed water-treatment facilities; many other potential contaminant sources could threaten human health. To address these threats, federal, state and local government have initiated a four-phase research effort to understand, model, and suggest best management practices for the ground-water resources in the region. This report is the result of Phase I of this effort, which was to develop the intellectual, organizational, and methodological foundation for the subsequent three phases. During Phase I, the various stores of hydrogeologic data were evaluated on their quality and usability to addressing the impact of the surmounting stresses on the regional ground-water system. The area under investigation includes the Tennessee counties of Shelby, Fayette, Hardeman, and Tipton, the Mississippi counties of Desoto, Marshall and Tunica, and the Arkansas county of Crittenden.
