Escherichia coli and Fecal-Coliform Bacteria as Indicators of Recreational WaterQuality

摘要

The report provides information on the use of E. coli and fecal-coliform bacteriaas indicators of recreational water quality. The report includes a literature review on (1) the development of recreational water-quality criteria, (2) the link between recreational water quality and the occurrence of swimming-associated illness, and (3) comparisons of E. coli and fecal-coliform concentrations and their relation to each other and to State water-quality standards. The report also presents the results of a study in which bacteriological water-quality data were collected from four Ohio rivers (Scioto, Olentangy, Cuyahoga, and Ohio Rivers) to determine if a statistical relation exists between E. coli and fecal-coliform concentrations.
