Drinking water taken from a deep aquifer protected by a semi-permeable layer of rock should be protected from many contaminants, including viruses. But viruses have been discovered in many deep Madison, Wis., water wells.
A team of Purdue University researchers has invented a prototype water-disinfection system that could help the world's 800 million people who lack safe drinking water.
Scientists at Kansas State University and seven other collaborating institutions were recently awarded $3.3 million from the National Science Foundation to conduct a-large scale study of how stream organisms influence water quality across North America.
About 20 percent of untreated water samples from public, private, and monitoring wells across the nation contain concentrations of at least one trace element, such as arsenic, manganese and uranium, at levels of potential health concern, according to a new study by the U.S. Geological Survey.
Output from the 10-megawatt AC project on 80 hectares of cleared land 50km southeast of Geraldton will contribute to offsetting the energy requirements of the Southern Seawater Desalination Plant.
With almost 100 million people in developing countries exposed to dangerously high levels of arsenic in their drinking water and unable to afford complex purification technology, scientists today described a simple, inexpensive method for removing arsenic based on chopped up pieces of ordinary plastic beverage bottles coated with a nutrient found in many foods and dietary supplements.
A national database on technologies to assess the conditions and rehabilitation of the underground pipes will be available to utilities and the general public, starting on Thursday, Sept. 1.

The EPA and the USDA announced a national partnership to protect Americans’ health by improving rural drinking water and wastewater systems.
The authors point out in the paper that the biggest problem with DPR is community acceptance, despite the fact that factors such as population growth and climate change mean that existing water supplies must go further in the future.
In response to a severe drought, the Australian government is pumping treated wastewater into the Gnangara Mound Aquifer. Some Australians, though, are not too thrilled about that.
Scientists have developed a way to transform ordinary sand — a mainstay filter material used to purify drinking water throughout the world — into a "supersand" with five times the filtering capacity of regular sand.
In response to community concerns, Kentucky’s Louisville Water Company thought up a gravity-fed riverbank filtration system that connects to a mile-and-a-half-long tunnel leading to a treatment plant.

During the last space shuttle flight, scheduled for July 8, 2011, astronauts will test a new method for recycling "used" water. Water is essential for life, and having access to water beyond Earth will be a major obstacle for future space explorers.
Virtual water – the amount of water it takes to produce goods or a service – has been suggested as a possible solution to this growing problem by using virtual water values to inform international trade deals. But researchers say that the existing amount of virtual water is not large enough to overcome the existing inequalities.
A proposed landfill near San Diego threatens a critical drinking water source, endangered species habitat and sacred Native American lands.
New Jersey’s demand for water challenges an already strained water supply, requiring new sources and those likely will be expensive, said John Bigelow, president of New Jersey American Water.
Trojan Technologies introduces the first-ever drinking water UV systems validated to fully comply with United States federal regulations for delivering 4-log inactivation of viruses, including the highly resistant adenovirus.
