The microbiologist will certainly be looking for counts of faecal coliforms such as E. coli, whose just habitat is the intestine, and whose life outside it from this source is short-lived; is viewed as the suitable indicator organism. Its existence in a sample of drinking water implies that the water is unsafe for human usage.
