Two researchers who tracked 10 town of Lincoln wells each month for a year estimated that in the area near the wells, agriculture contributed 96 percent of the nitrates to groundwater, and septic systems contributed 4 percent.
Eight Department of Energy national laboratories, including Lawrence Berkeley National Laboratory, are combining forces with the National Center for Atmospheric Research, four academic institutions and one private-sector company in the new effort.
Plastic materials used in food packaging are made up of small molecules or monomers which, together with their additives, can migrate into the product during packaging manufacturing, filling or storage.
This guide is to show basic ideas and policies indispensable for restoring desirable river environments in Asia, raise the interest of readers in a river nearby, create an opportunity toward new projects for river restoration, and also support current river restoration projects.
This is published by the Asian River Restoration Network.
As the oil and gas drilling technique called hydraulic fracturing (or "fracking") proliferates, a new study on the contents of the fluids involved in the process raises concerns about several ingredients.
When it comes to understanding America’s coastal fisheries, anecdotes are gripping – stories of a choking algae bloom, or a bay’s struggle with commercial development. But when it comes to taking action, there’s no beating big data.
A new study, the Projected Impact of Climate Change on Water Availability and Development in the Koshi Basin, Nepal, by researchers from the International Water Management Institute (IWMI) in Nepal, assesses the likely impact of climate change on water resources development in the Koshi River basin and generates projections for the 2030s and 2050s.
Erosion is a major threat for coasts worldwide, beaches in particular, which constitute one of the most valuable coastal landforms. Vulnerability assessments related to beach erosion may contribute to planning measures to counteract erosion by identifying, quantifying and ranking vulnerability.
Sewer systems are among the most critical infrastructure assets for modern urban societies and provide essential human health protection. Sulfide-induced concrete sewer corrosion costs billions of dollars annually and has been identified as a main cause of global sewer deterioration.
Though researchers cautioned their study of hydraulic fracturing, or fracking, employed at two Wyoming geological formations showed no direct evidence of water-supply contamination, their work is certain to roil the public health debate over the risks of the controversial oil and gas production process.
As murky water snakes through a man-made wetland between Dallas and Houston, its shallow ponds of lush vegetation slowly filter out phosphorous and nitrates until, a week later, the water runs clear as a creek into the area drinking supply.
Once considered marvels of engineering and the best way to provide power and water to towns and cities across America, dams are now considered harmful relics that damage river ecosystems and contribute to global warming.
Minnesota’s approach to protecting wild rice from sulfate pollution faces a key test this week. A group of scientists recruited from around the country will evaluate the state’s analysis of a series of research projects designed to determin
