A survey of heterotrophic bacteria and coliforms in the water of old and new distribution networks [PDF]

Journal of Advances in Environmental Health Research, 2016
Controlling the microbiological quality of water is important for its uses. Microbiological requirements of drinking water ensure the absence of coliforms, but may indicate the potential presence of other potentially pathogenic microorganisms and viruses
