Researchers Find Substantial Amount of Mercury Entering the Ocean through Groundwater
Researchers from the Woods Hole Oceanographic Institution (WHOI) have found a new and substantial pathway for mercury pollution flowing into coastal waters. Marine chemists have detected much more dissolved mercury entering the ocean through groundwater than from atmospheric and river sources. view more (2007-03-22)
Drinking water in Gaza Strip contaminated with high levels of nitrate
Palestinian and German scientists have recommended to the authorities in the Gaza Strip that they take immediate measures to combat excessive nitrate levels in the drinking water. view more (2008-08-15)
Sophisticated monitoring array to address mystery of uranium plume
Scientists have puzzled for years about why uranium contamination in groundwater continues to exceed drinking water standards in an area located at the south end of the Hanford Site. The Department of Energy wants answers to why the uranium persists. view more (2008-09-18)
Satellite-based findings by UCI, NASA reveal significant groundwater loss in Central Valley
New space observations reveal that since October 2003, the aquifers for California's primary agricultural region - the Central Valley - and its major mountain water source - the Sierra Nevada - have lost nearly enough water combined to fill Lake Mead, America's largest reservoir. view more (2009-12-15)
Water table depth tied to droughts
Will there be another "dust bowl" in the Great Plains similar to the one that swept the region in the 1930s? view more (2008-09-30)
Tunisia: Small Dams Useful For Maintaining Aquifer Levels
In Tunisia, fierce, sometimes catastrophic, flooding is favoured by sudden bursts of rainfall and by erosion- prone soils. This is especially the case in the large wadis in the centre of the country. Large amounts of sediment flow into reservoirs, reducing the useful life of the dams and destroying and depleting the soils in the drainage basins.... view more... (2001-10-11)
Groundwater sampling goes tubular
"Leave No Trace" is a popular ethic for outdoor recreationists who advocate a natural landscape. Now it is also applicable to groundwater sampling collection sites along the Columbia River in southeastern Washington State. view more (2005-10-06)
A new, dechlorinating bacterium
Several industrial activities of the previous decades resulted in serious contamination of groundwater. For instance, polyvinyl chloride (PVC) production and related activities cause annual underground releases of 137 tonnes of 1,2-dichloroethane (1,2-DCA) in the USA (1988-1999). The latter molecule has an environmental half-life of about 50... view more... (2003-04-22)
More recycling on the farm could reduce environmental problems
Growing environmental problems resulting from farming argue for a shift toward practices that use lower inputs of pesticides and energy and more recycling of energy and materials. view more (2007-05-01)
MTBE contamination: A microbial approach for groundwater
Max Häggblom's Rutgers laboratory has taken an important step on the path to using microbes to rid the environment of methyl tertiary-butyl ether (MTBE), a toxic gasoline additive now classified as a potential human carcinogen. view more (2006-03-22)
Arsenic contamination lacks one-size-fits-all remedy
Though a worldwide problem, arsenic contamination of drinking water does not have a universal solution. view more (2007-12-11)
Increased flow of groundwater after earthquakes suggests oil extraction applications
The most obvious manifestation of an earthquake is the shaking from seismic waves that knocks down buildings and rattles people. Now researchers have established a more subtle effect of this shaking—it increases the permeability of rock to groundwater and other fluids. view more (2006-06-29)
Chloride Found at Levels that Can Harm Aquatic Life in Urban Streams of the Northern U.S.--Winter Deicing a Major Source
Levels of chloride, a component of salt, are elevated in many urban streams and groundwater across the northern U.S., according to a new government study. view more (2009-09-17)
Treated wood poses long-term threat
Arsenic from treated lumber used in decks, utility poles and fences will likely leach into the environment for decades to come, possibly threatening groundwater, according to two research papers published online Wednesday. view more (2005-12-27)
MIT scientists pinpoint origin of dissolved arsenic in Bangladesh drinking water
Researchers in MIT's Department of Civil and Environmental Engineering believe they have pinpointed a pathway by which arsenic may be contaminating the drinking water in Bangladesh, a phenomenon that has puzzled scientists, world health agencies and the Bangladeshi government for nearly 30 years. view more (2009-11-16)
Clemson research cleans up with edible oil
Oil and water don't mix, and that could be the key to edible vegetable-based oil being the answer to contaminant clean-up. view more (2006-09-14)
Research to secure a safe water supply
World Water Day on Sunday, 22 March aims to raise public awareness of the increasing scarcity of clean drinking water on our planet. In a densely populated world, droughts and floods are causing more damage than ever before. view more (2009-03-20)
Aswan Obelisk Quarry more than meets the eye
The unfinished Obelisk Quarry in Aswan, Egypt, has a canal that may have connected to the Nile and allowed the large stone monuments to float to their permanent locations, according to an international team of researchers. This canal, however, may be allowing salts from ground water to seep into what has been the best preserved example of obelisk... view more... (2007-10-17)
UMass Amherst Researchers Discover That Microbes Can Produce Miniature Electrical Wires†
Researchers at the University of Massachusetts Amherst have discovered a tiny biological structure that is highly electrically conductive. This breakthrough helps describe how microorganisms can clean up groundwater and produce electricity from renewable resources. It may also have applications in the emerging field of nanotechnology, which... view more... (2005-06-24)
Scientists ramp up ability of poplar plants to disarm toxic pollutants
Scientists since the early '90s have seen the potential for cleaning up contaminated sites by growing plants able to take up nasty groundwater pollutants through their roots. Then the plants break certain kinds of pollutants into harmless byproducts that the plants either incorporate into their roots, stems and leaves or release into the air. view more (2007-10-16)
