What are E. coli and enterococci?

E. coli and intestinal enterococci are indicator bacteria for fecal contamination. Their presence suggests sewage or animal waste in the water, which may contain harmful pathogens. The EU Bathing Water Directive (2006/7/EC) classifies water quality based on these two indicators.
