Ceramic Water filters used for household disinfection in developing countries

GENEVA — A study of four household-based technologies for water disinfection has found that household chlorination is the most cost-effective of the four for preventing diarrhea outbreaks in those parts of the developing world where piped-in public water is not feasible, a new World Health Organization (WHO) study has found.

In their recently released study, Dr. Thomas Clasen of the London School of Hygiene and Tropical Medicine and Laurence Haller of WHO note that diarrhea kills an estimated 1.8 million people annually worldwide, and accounts for 17 percent of deaths of children under age 5 in developing nations. Most of these deaths are attributable to poor drinking water supplies or poor sanitation.

Analyzing information from water quality programs in 28 nations, Clasen and Haller concluded that household-based chlorination, with a cost per disability-adjusted life year (DALY) of US$53, was the most cost-effective among the four technologies studied for improving water quality at the household level.

Other DALY cost-effectiveness ratings for household-level disinfection technologies calculated in the study were: solar disinfection, US$61; ceramic filtration, US$142; and household flocculation/disinfection, US$472.

Nitrates pose potential threat to Lake Superior MINNEAPOLIS/ST. PAUL, MN — Nitrate levels continue to rise in Lake Superior, which contains 10 percent of the Earth’s supply of surface fresh water, and push lake water closer toward being considered unsafe to drink, according to a May 31 University of Minnesota press release.

Heightened MTBE threat for New York communities

RONKONKOMA, NY — A recently released study shows that aquifers which supply the drinking water for this Long Island community face a greater threat then previously thought from the fuel additive methyl tertiary butyl ether (MTBE), according to a February 23 Newsday article. The New York state Department of Environmental Conservation released a study on February 22 that showed MTBE plumes from previously undetected petroleum spills migrating toward aquifers that supply public drinking water.
