Variability in the Characterization of Total Coliforms, Fecal Coliforms and Escherichia coli in Recreational Water Supplies of North Mississippi, USA
The fecal coliform, Escherichia coli, is a historical organism for the detection of fecal pollution in water supplies. The presence of E. coli indicates a potential contamination of the water supply by other more...
