Evaluation of the H2S paper strip test - A field test for assessing microbiological quality of water

Epidemics arising from drinking water contaminated with faecal matter are a global health problem. Standard methods currently used for routine microbiological testing of drinking water have many limitations. The H2S paper strip test appears to be a sensitive, simple and inexpensive procedure for screening of water supplied towards potential contamination. It eliminates complicated procedures and costly chemicals and lab equipment.
