Escherichia coli or E. coli is a type of bacteria found in the intestines and feces of warm-blooded animals, including humans. While E. coli are not generally harmful themselves, their presence indicates feces or sewage contamination, which raises the possibility of disease-causing bacteria or viruses in the water. The presence of E. coli is used to determine if the public needs to be notified of a health risk.
The Division of Water Quality (DWQ) and local health departments sample surface waters for E. coli from May to October of each year. The health departments issue advisories when E. coli levels exceed health-based water quality standards.
