摘要

Waterborne diseases are a major health problem in many cuntries. Faecal contamination of drinking water is one of the main cause of these disease outbreaks as many pathogens are carried through human feaces. At present, the quality of drinking water is ensured by testing he water sample for total coliforms and thermotolerant coliforms of E. coli. However when applied in remote areas the standard methods have various limitations. The distance to laboratory facilities and the high cost of anlaysis restrict water quality assessment in remote areas and in developing countries. Under such circumstances an on-situ bacteriological test is considered to be highly essential for routine water quality testing. Teh H_2S paper Strip Method has been developed as a quick, inexpensive and easy to use method to test drinking water for remote and rural areas. With this method H_2S producign bacteria cause water sample to turn black when faecal contamination is present.
