Drinking Water Week 2012 began May 7
The American Water Works Assn. (AWWA) kicked off Drinking Water Week 2012 on May 7 with a call to “Celebrate the Essential” throughout North America.
Throughout the week, AWWA and its partners will celebrate water by recognizing the essential role drinking water plays in our daily lives, with special attention to water infrastructure, the economy and careers in the water profession.
Dr. Ashok Gadgil received $100,000 Lemelson-MIT Award for Global Innovation for solutions to global water crisis, among other accomplishments
The Lemelson-MIT Program recently announced Dr. Ashok Gadgil as the recipient of the 2012 $100,000 Lemelson-MIT Award for Global Innovation in recognition of his steady pursuit to blend research, invention and humanitarianism for broad social impact.
Gadgil is a chair professor of safe water and sanitation at the University of California, Berkeley, and director of the Environmental Energy Technologies Div. at Lawrence Berkeley National Laboratory, whose diverse inventions and sustainable innovations are helping those in the developing world to live healthier, safer lives.
This is the fourth year that the company has sponsored the initiative
Culligan Intl. has declared May Drinking Water Month. This is the fourth year Culligan has sponsored the month-long initiative, which complements other government- and association-sponsored events like the American Water Works Assn.'s Drinking Water Week, May 6 to 12.
"Drinking water helps us maintain energy, improve concentration, moderate body temperature and even ward off the common cold," said Curt Hilliard, Culligan's senior vice president of marketing. "Raising awareness about the importance and role water plays in our lives is what Drinking Water Month is about."
USGS analysis examined concentrations of chloride, dissolved solids and nitrate in groundwater
There was no change in concentrations of chloride, dissolved solids or nitrate in groundwater for more than 50% of well networks sampled in a new analysis by the U.S. Geological Survey (USGS) that compared samples from 1988 to 2000 to samples from 2001 to 2010. For those networks that did have a change, seven times more networks saw increases as opposed to decreases.
Approximately 6,000 public water systems will begin monitoring 28 chemicals and two viruses beginning in 2013
The U.S. Environmental Protection Agency (EPA) recently published a list of 28 chemicals and two viruses that approximately 6,000 public water systems will monitor from 2013 to 2015 as part of the agency’s unregulated contaminant monitoring program.
The program collects data for contaminants suspected to be present in drinking water but that do not have health-based standards set under the Safe Drinking Water Act.
The toxic New York site has contaminated the public water supply
The U.S. Environmental Protection Agency (EPA) has finalized its plan to demolish a building, dig up contaminated soil and sediment and treat the groundwater at the Crown Cleaners of Watertown Inc. Superfund site in Herrings, N.Y.
A wide range of research and development is being conducted to solve the challenges of providing clean water, with a significant emphasis on drinking water. The research focus has included advanced membrane technology; changing water chemistry to suit the remediation technology of choice; and media modification for increased selectivity, activity and capacity.
The purpose of this study is to focus on sorptive media modification for improved performance.
Treatment media advancements through application of nano-science
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.
