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.
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
Over the years, the public has become more aware of drinking water quality issues. Urban development has placed increased stress on water resources, which in turn has increased the need for cost-effective methods to treat drinking water. This is true regardless of whether the installation is at a single point of use (POU) or at the point of entry (POE) for treating all water used in the home.
Choosing the right treatment option for the water supply
In recent days, groundwater has been gaining attention. Increased hydraulic fracturing operations have caused controversy over potential methane gas contamination. Reports indicate that groundwater aquifers, especially in the drought-prone southwestern U.S., are being depleted more quickly than they can be recharged. Surveys, like the one recently released by the U.S. Geological Survey (USGS), reveal that contaminants such as arsenic are widespread in the nation’s water wells.
More than ever, sustainable surface and groundwater supplies are essential to communities across North America and around the world. The strains of industry and agriculture on groundwater are noticeable as pressures on water supplies intensify and supply patterns change. The increase in agriculture over vulnerable aquifers, climate change and hydrocarbon production are impacting water quality. Unregulated use or uncontrolled flow of groundwater can cause water quality degradation and conflict between water users.
Small drinking water systems opt for POE UV treatment
When McMaster University in Hamilton, Ontario, Canada, set about constructing its new Engineering Technology Building, it used the latest state-of-the-art technology not only to achieve U.S. Green Building Council Leadership in Energy and Environmental Design (LEED) Gold certification, but also to create a living laboratory to train students on the building systems of the future. One of the components is a rainwater harvesting system that collects, filters and disinfects rainwater for non-potable and potable use in the building.
