TL;DR: Although improved sources generally delivered ‘safe’ water at the point-of-supply, 12% of source samples were contaminated and as such were ‘unsafe’ in household storage, and this significant deterioration in microbial quality of water from improved sources was seen in both countries.

183. Use of Handheld Computers for Collecting Water Quality Data in Developing Countries
James S. Wright,Stephen W. Gundry,Bettina Genthe,M. du Preez,S. Moyo,Natasha Potgieter,J. Ndamba +6 more
TL;DR: A novel system for recording and storing details of water samples collected from rural African households and the water sources that they use makes use of handheld computers for data entry instead of paper-based records, significantly reducing the lag-time between data collection and analysis.
