Targeting appropriate interventions to minimize deterioration of drinking-water quality in developing countries.

In developing countries, it has been observed that drinking-water frequently becomes recontaminated following its collection and during storage in the home. This paper proposes a semi-quantified 'disease risk index' (DRI) designed to identify communities or households that are 'most at risk' from consuming recontaminated drinking-water. A brief review of appropriate physical and educational intervention measures is presented, and their effective use is discussed.

The importance of domestic water quality management in the context of faecal-oral disease transmission.

The deterioration of drinking water quality following its collection from a community well or standpipe and during storage in the home has been well documented. However, there is a view that post-supply contamination is of little public health consequence. This paper explores the potential health risk from consuming re-contaminated drinking water.

Mechanisms leading to post-supply water quality deterioration in rural Honduran communities.

Drinking water can become contaminated following its collection from communal sources such as wells and tap stands, as well as during its storage in the home. However, the mechanisms leading to contamination between the points of supply and consumption have not been well documented. This study carried out field-based experiments in three rural Honduran communities to investigate the potential for contamination through hand contact, method used to draw water, and dirty collection containers.

Water quality deterioration: a study of household drinking water quality in rural Honduras.

There is growing awareness that drinking-water can become contaminated following its collection from communal sources such as wells and tap-stands, as well as during its storage in the home. This study evaluated the post-supply drinking-water quality in three rural Honduran communities using either a protected hand-dug well or borehole supply. Water management practices were documented as a basis for further research to improve household drinking-water quality.
