The microbiologist will certainly be looking for counts of faecal coliforms such as E. coli, whose only environment is the intestine, and whose life outside it is short-term; is their explanation viewed as the optimal indication organism.

Suggested media for coliforms and E.in cooling towers need to be lugged out on a regular basis and need to belong to a plant's program of screening.
