ABSTRACT
This is a case study of a site investigation in the Dougherty Karst Plain topographic province in southwestern Georgia, USA, with particular emphasis on understanding a complex covered karst aquifer system’s flow paths and their effects on transport of contaminants off site. Because of their high inherent variability, hazardous waste sites in karst terrains are difficult and expensive to properly investigate. A suite of geochemical and statistical data analysis tools, more often used in regional water quality investigations, has been used to better define local hydrostratigraphy and flow regimes and augment limited drilling, core, and boring data in the interpretation of local areas of recharge, discharge, and interaquifer mixing and a better understanding of the general site characteristics. These tools include water type plots, saturation indices, and elemental ratios.
