Bacteria water test
Bacteria water testing. Female researcher removing a membrane filter from a bacterial culture dish with forceps as she tests a water sample for bacterial contamination. The water sample was drawn through the membrane by a pump. Any bacteria present will be trapped in the membrane, which is incubated in the culture dish to allow them to multiply. The bacteria can then be identified. Bacteria are responsible for water-borne diseases such as typhoid fever and cholera. Photographed in part of the Public Health Service Laboratory, UK.
