Evaluation of a simple screening test for the quality of drinking water systems.
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 22-37°C and correlated well with the presence of total coliform bacteria (96%, 28°C).
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 deep-tube well water, where complete absence of coliforms is required.
