MODEL RELEASED. Drinking water testing. Microbiologist loading a growing medium onto a petri dish with a pipette. The prepared dishes will be used to test whether coliform bacteria are present in drinking water samples. The presence of this type of bacteria indicates that the water has been contaminated by faecal matter.
