What are enterococci and e. coli?
A. Enterococci and e. coli are bacteria that are found in the intestine of all warm-blooded animals, including humans. Because these bacteria are easy to detect and commonly found in animal and human waste, they are used as indicators of recreational water quality conditions. Enterococci and e. coli are the organisms recommended by the US Environmental Protection Agency (EPA) to measure fecal contamination in recreational water.
