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.

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:
The global need for point-of-use (POU) drinking water treatment products with microbiological reduction or purification claims has grown in recent years. The proliferation of these products is evident in developing countries such as Brazil, China, India and Mexico, where water quality is of concern to the general population.
Because microbial reduction or purification is a significant health claim, the efficacy of these products’ performance is paramount for consumer protection.
POU systems meet global standards for microbial reduction
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.
Rainwater harvesting system provides alternative to well water
Six months ago I opened the refrigerator to pour myself a glass of water from my pour-through pitcher. As I was filling my glass, I realized I could not remember the last time I changed the carbon filter. I had been thinking about replacing the filter for a while—a really long while.
Determining when to change your activated carbon filter
