Thermotolerant faecal coliforms are indicator bacteria, which can form colonies at 44 degrees centigrade and can provide evidence of faecal contamination of water.
Membrane filtration is a means of testing the quality of water.
This film presents an overview of the process. Water is filtered though a membrane having pore sizes smaller than the size of a bacterium.
As water is filtered, bacteria are collected on the surface of the membrane.
The bacteria can then be incubated to produce visible colonies suitable for analysis.

This film looks at three methods of measuring turbidity in the field:
• measuring turbidity with a turbidity tube; • the Chinese method; and • measuring turbidity using a turbidity meter.
The first two methods are simple means of measurement.
The third involves the use of an electronic device that is more complex to use but is a more accurate means of measurement.

This film looks at how chemicals in water can be measured, using chlorine, nitrate and iron as examples.
Although the examples shown here were undertaken in a laboratory, with portable test kits, these methods can be used in the field too.
