2. Bacteriological, mycological
3. Protozoological, microscopical
4. Allergic test, serological

Bacteriological water testing is a method of collecting water samples and analysing those samples to estimate the numbers of bacteria present. This note presents the background to the testing of water samples to determine whether disease-causing bacteria, in particular faecal coliforms, are present in water.
