Association of Supply Type with Fecal Contamination of Source Water and Household Stored Drinking Water in Developing Countries: A Bivariate Meta-analysis

Monitoring drinking water focuses on water supply at the source but less is known on whether water quality differences at the source persist in water stored at home. In Environmental Health Perspectives, we performed a bivariate meta-analysis of 45 studies and found water quality deteriorated significantly between the source and household stored water (HSW). However, piped water is less likely to be contaminated at the source and in HSW than non-piped. A focus on upgrading water services to piped supplies may improve water quality for all, including those drinking stored water.
