Bacterial indicator testing is relatively inexpensive, and is one of the main modes of water quality management
in use today. Faecal bacteria are considered to be good indicators of faecal contamination as they are present in
the faeces of humans and warm-blooded animals. Total coliforms, faecal coliforms and enterococci are indicator
bacteria that have been used for decades to infer the presence of other potentially harmful pathogens in
recreational waters.
