- Drinking water : less than 18 hours to detect 1 or more coliforms in 100 ml water.
- Surveillance of beach water : less than 8 hours to detect 2000 or more E.Coli in 100 ml sea water.

· Surveillance of quality of drinking water, underground water, surface water, ...
· Surveillance of quality of beach water, sea water, waste water after disinfection for example, ...

Total coliforms that are present in a larger number than E.Coli are an early indicator of a possible contamination of drinking water and the Colilert® 3000 allows :
