Study shows promising results in using the sun's ultraviolet rays to decontaminate water at high altitudes

Research shows that solar water disinfection (SODIS) may be just as effective at decontaminating Escherichia coli (E coli) infected water at high altitudes as it is at low altitudes. The results of a new study appearing in the Wilderness Medical Society's official journal Wilderness & Environmental Medicine show promise for improving global access to safe drinking water.
