Abstract

Abstract.

To assess water contamination and the relative effectiveness of three options for point-of-use water treatment in South India, we conducted a 6-month randomized, controlled intervention trial using chlorine, seeds, a closed valved container, and controls. One hundred twenty-six families participated. Approximately 70% of public drinking water sources had thermotolerant coliform counts > 100/100 mL. Neither seeds nor containers reduced coliform counts in water samples from participants' homes. Chlorine reduced thermotolerant coliform counts to potable levels, but was less acceptable to participants. Laboratory testing of seeds in water from the village confirmed the lack of reduction in coliform counts, in contrast to the improvement seen with seeded distilled water. This discrepancy merits further study, as was effective in reducing coliform counts in other studies and compliance with use in this study was high.
