RESUMO
A simple and inexpensive assay for detection of H2S producing bacteria in drinking water was evaluated in Paraguay. Using an improved preparation procedure, results were basically temperature independent in the range of 22-37ºc and correlated well with the presence of total coliform bacteria (96 percent, 28ºc). The assay was not suitable for control of surface water and dug well water due to the frequent presence of non-faecal coliforms. However, it was very suitable for routine control of high quality water-systems, like treated community water systems or deeep-tube well water, where complete absence of coliforms is required a laboratory technician or special equipament. Its use permits a cost-effective routine control of high quality community water systems in developing countries. In addition, this test turned out to be an effective educational tool for heightening the awareness of people towards dangers of unclean drinking water
