In many developing areas in Africa, accessing clean drinking water is a serious challenge for thousands of communities. The only sources of water available to their residents often are overrun with bacteria, waste and harmful contaminants. Many times, a family’s only way to obtain potable water is to walk long distances to the nearest well or other groundwater source. Such a task has several adverse effects, particularly on women and children, who may spend much of their time retrieving low-quality water for their families instead of attending school.
Nonprofit organizations work to provide clean water in Africa
The Embry-Riddle Aeronautical University students recently showed their design in Washington, D.C.
A portable solar-powered water purifier designed for use by disaster responders has put a team of student engineers from Embry-Riddle Aeronautical University in the running for a national award sponsored by the U.S. Environmental Protection Agency (EPA).
The group, led by Embry-Riddle engineering professors Marc Compere, Mark Fugler and Yan Tang, was one of 45 teams selected by the agency from among 150 applicants around the country and given funding to continue with development of its design.
Researchers found that solar disinfection coupled with lime juice removed harmful bacteria “significantly” faster than solar disinfection alone
A team of researchers from the Johns Hopkins Bloomberg School of Public Health and the Johns Hopkins School of Medicine found that adding lime juice to water that is treated with a solar disinfection method removed detectable levels of harmful bacteria such as E. coli significantly faster than solar disinfection alone.
The results are featured in the April 2012 issue of American Journal of Tropical Medicine and Hygiene.
Court dismissed lawsuit that sought to stop a metropolitan water district from adding hydrofluosilicic acid to its public drinking water

University of Michigan to co-sponsor studies focusing on gold mining in Ghana and stomach cancer in Peru
The University of Michigan's Graham Sustainability Institute and the Center for Global Health are co-sponsoring two research projects addressing water quality impacts on public health, one in Ghana and the other in Peru.
Each of the projects, which are called integrated assessments, will receive $350,000 over the next three years.
Article claimed drinking bottled water can contribute to tooth decay
The International Bottled Water Assn. (IBWA) issued the following statement regarding a March 6 New York Times article concerning recent increases in children’s cavity rates:
Like assembling a jigsaw puzzle, regulations for drinking water products must be understood and put together correctly to find a solution and see the entire regulatory picture. Unfortunately, the pieces can be difficult to assemble.
Certification programs help navigate complex international standards
Finding potable water can be a difficult task for rural communities in sub-Saharan Africa. South African nongovernmental organization Roundabout Water Solutions (RWSSA) found an innovative method for communities to pump and store clean drinking water: playground equipment that doubles as a pumping apparatus. Raissa Rocha, editorial intern at Water Quality Products, recently checked in with Sandra Hayes, administrative and donor relations manager at RWSSA, to discuss the systems and the organization’s efforts.
Raissa Rocha: How do these systems work?
Rainwater harvesting and storm water recycling are similar processes, but rainwater harvesting usually involves collecting water from cleaner surfaces, such as roofs, while storm water typically is ground-level runoff. Both require collecting, storing and conserving rain for later use.
