Bacteriological water analysis - Wikipedia
Bacteriological water analysis - Wikipedia

Bacteriological water analysis, is a method of analysing water to estimate the numbers of bacteria present and, if needed, to find out what sort of bacteria they are. It represents one aspect of water quality. It is a microbiological analytical procedure which uses samples of water and from these samples determines the concentration of bacteria. It is then possible to draw inferences about the suitability of …
