The Use Of Down-Hole Video To Evaluate Parameters Affecting Removal Of Storm Water Runoff Into A Karst Aquifer In Bowling Green, Kentucky, Philip Reeder

Masters Theses & Specialist Projects

Due to recent land use changes, runoff has greatly increased In Bowling Green, necessitating the drilling of nearly 600 drainage wells to direct storm water into the Lost River Karst Aquifer. Research was conducted to (1) differentiate areas of the city as optimal for removal of storm water runoff, (2) correlate lithologic features between wells, and (3) determine optimal depths to which new drainage wells should be drilled. This was accomplished using maximum capacity tests, correlation of lithologic features between wells and comparing void density to depth below the land surface.

It was only possible to develop general trends in …

Enteric Contamination Of An Urban Karstified Carbonate Aquifer: The Double Springs Drainage Basin, Bowling Green, Kentucky, Geary Schindel

Masters Theses & Specialist Projects

Biological and chemical analysis of water samples, collected from surface and subsurface streams was preformed to determine the quantity and biologic sources of enteric contamination in the Double Springs Groundwater Basin, an urban karstified carbonate aquifer under Bowling Green, Kentucky. Major flow paths, drainage basin boundaries and geologic/hydrologic relationships were identified for the basin. Analysis of biologic contaminates using fecal coliform /fecal streptococcus counts and ratios were conducted for baseflow and storm events and related to the Double Springs hydrographs. Analysis was also conducted to determine the source of sulfides responsible for the growth of sulfur fixing bacteria in the …

Nonpoint Agricultural Pollution In A Karst Aquifer: Lost River Groundwater Drainage Basin, Warren County, Kentucky, Nancy Tucker

Masters Theses & Specialist Projects

Chemical analysis of samples collected from subsurface streams and wells were analyzed to identify nonpoint pollutants in karst aquifers resulting from agricultural land use. Major flow paths and travel times taken by nonpoint pollutants were identified. A land use limitation map showing areas where agricultural activities may results in nonpoint pollution of the karst aquifer was prepared. A groundwater susceptibility map was prepared to show areas of the karst aquifer most susceptible to groundwater contamination by nonpoint pollution resulting from agricultural land use.

Research findings revealed that pollutant concentrations may reach levels thousands of times greater during high discharge events …
