A study to determine the validity and predictive value of the hydrogen sulphide screening test for water quality compared to a standard multiple-tube technique test was undertaken. The hydrogen sulphide test was found to be highly sensitive and specific with a high predictive value. It is recommended as a screening test for water quality in developing countries where resources are limited. It will be especially useful in monitoring improvement in rural water supplies.
