Water Quality Laboratories in Colombia

Monitoring water quality is a substantial logistical challenge, particularly in resource-constrained settings. In this study, reported in Science of the Total Environment, researchers from The Water Institute collaborated with researchers from Colombia and the UK to quantify this challenge in urban and rural Colombia. The spatial analysis combined data on laboratory locations with detailed census data and demonstrates the difficulties in undertaking laboratory-based microbiological water testing in rural areas. The approach presented here provides a new means of using geographic information systems (GIS) to support water quality monitoring in such areas.
