Faecal coliform bacteria = heat tolerant coliform and E. coli

These bacteria are normally found in the intestines of humans and mammals, but are usually harmless. These bacteria do not multiply outside the human body - especially in the bathing water. Therefore, they are a useful indicator of contamination by human waste. The presence of faecal coli may simultaneously comprise of other pathogens that may also be present in the intestine. Inversely, if there are no faecal coli in the bathing water, then you can be pretty sure that no other harmful intestinal bacteria are present in the water. <ref name ="isa" />

The concentration of faecal coliform bacteria is usually measured in CFU/100 ml = E.Coli = similar coliform = heat tolerant.

Intestinal Enterococci (Synonym: Faecal streptococci)

A positive detection of enterococci indicates the high probability of faecal contamination. The bacteria hardly multiply in the water and are an evidence of past contamination. They are particularly resistant to chlorine.
