Book Description
Clean river water is used daily for numerous purposes. It can serve as a drinking water supply, be used in industries or serve for various recreational activities. Watersheds that are not impacted by human influence have the ability to self-regulate water quality, but those impacted by human usage become susceptible to point and nonpoint source pollution. Pollution in turn destroys river ecosystems and creates an actual health hazard for humans. There are several methods for testing water quality. To assess waterborne disease risk, microbial indicators are used. This study included testing for fecal coliforms, a subgroup Escherichia coli, and enterococci. Testing was conducted in the east branch of Eightmile River, located in East Haddam, Lyme and Salem, Connecticut. Water was tested for microbial indicators at six sites, bi-weekly for seven months. For most of the sampling period, all six test sites stayed within designated water quality standards for the State of Connecticut's Department of Environmental Protection, Class A. Occasional excursions from those limits happened at all sites at various times. In the case of fecal coliforms and E. coli, results above the water quality criteria were closely related to rain events in the area. For enterococci, high counts seemed to be more correlated with water temperature.
