Tryptophan-Like Fluorescence And Non-Point Source Pollution In Karst Basins, Inner Bluegrass Region, Kentucky, Ryan Dapkus

Theses and Dissertations--Earth and Environmental Sciences

Typically, the degree of fecal contamination of water is assessed by the concentration of thermotolerant coliforms, like E. coli. This method is time-consuming, taking > 18 hours between the start of incubation and subsequent enumeration. The current study examines the utility of monitoring tryptophan-like fluorescence (TLF) using in-situ fluorometers as a proxy for fecal contamination, particularly E. coli. Relative timing of discharge peaks and TLF peaks is considered, as well as differences in E. coli concentrations and major anion concentrations between two different basins that were monitored weekly. Results indicate that TLF is somewhat useful in the prediction of …

Identification Of Soil-Water Chemical Parameters For The Prediction And Treatment Of Suspended Solids In Surface Water Reservoirs Of Coal Mine Lands, V. P. Evangelou, J. H. Grove, R. I. Barnhisel

KWRRI Research Reports

High concentrations of suspended solids in coal mine sedimentation ponds are a factor in lowering water quality. This study focuses on the influence dissolved solids have on concentration and settling of suspended solids. Water samples from sedimentation ponds in Eastern and Western Kentucky were used to evaluate water composition in such ponds. Spoil samples from surface mine sites in both parts of the state were used to evaluate water composition released from the spoils upon introducing water.

The results demonstrate that water quality emanating from coal spoils of Eastern and Western coal mines is dependent on the type of spoil …
