TL;DR: To assess the extent and causes of microbiological contamination of household drinking water between source and point‐of‐use in developing countries, a large number of countries in the region are surveyed.

TL;DR: No clear relationship was found with point-of-use water quality, although interventions did significantly reduce diarrhoeal incidence, and home water treatment and storage interventions were also found to reduce cholera.

TL;DR: The criterion used by the MDG indicator to determine whether a water source is safe can lead to substantial overestimates of the population with access to safe drinking-water and, consequently, also overestimates the progress made towards the 2015 MDG target.

TL;DR: Survey data is used to calculate household socio-economic-status (SES) indices in seven countries to assess inequalities in access as indicated by type of improved water source, use of safe water, and a combination of these, showing that use of a binary "improved"/unimproved categorization masks substantial inequalities.

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.
