Fecal Contamination of Drinking-Water

Global access to safe drinking water is monitored by the World Health Organization using the indicator “use of an improved source,” such as a protected dug well. But accessing water through protected wells does not necessarily mean a household in the developing world will have safer drinking water than if they used more traditional, unprotected water sources. In fact, fecal contamination still occurs in about 25 percent of water from improved sources. These are the findings of a new analysis conducted by The Water Institute at UNC and published in PLOS Medicine.
