Role of Suspended Sediment in Facilitating Pathogen Transport in Inner Bluegrass Karst Aquifers

The objectives of this study were to characterize the relationship   between suspended sediment and pathogen indicators at two springs   draining karst basins with contrasting land uses (urban and   agricultural) in Woodford County, Kentucky. Blue Hole Spring is   located in Versailles; spring SP-2 is at the University of Kentucky   (UK) Animal Research Center (ARC). At each site, specific   conductance (SC), pH, and temperature (T) were manually measured   weekly from fall 2  2 to spring 2  4. Concentrations of fecal   coliform bacteria (FC), total coliforms (TC), atypical coliforms   (AC), male-specific coliphage (MSP, an indicator of viruses in waste   water), and major ions were measured biweekly. Discharge at SP-2,   stream stage at Blue Hole (which has been correlated to discharge),   SC, pH, T, and turbidity were monitored continuously by sensors   linked to digital data loggers. Bed sediments at SP-2 and the   sinkhole feeding it were analyzed for mineralogy, petrology,   particle size, total organic carbon (TOC), and total inorganic   carbon (TIC). During two storms, SC, T, FC, TC, AC, MSP, and total   suspended solids (TSS) were measured at both springs, and suspended   sediment samples were collected at SP-2 for the same analyses   previously performed on bed sediments.    (karst environment); (suspended sediment); (pathogens); (coliform);   (microbial); (bacterial); (microbes); (bacteria)
