Treatment system will clean up contaminated groundwater at Superfund sites in Torrance, Calif.
The U.S. Environmental Protection Agency (EPA) announced the start of construction of a groundwater treatment system that will clean up groundwater contamination from past operations at the Montrose and Del Amo Superfund sites in Torrance, Calif. The treatment system is expected to be completed in 18 months at an estimated cost of $15 million and will be used to remove chlorobenzene, benzene and other industrial chemicals used to manufacture DDT and synthetic rubber from the groundwater.
The week focuses on America’s need to protect and maintain water from underground aquifers
The International Bottled Water Assn. (IBWA) is a sponsor of National Groundwater Awareness Week, March 10 to 16, 2013. The annual commemoration marking America’s need to protect and maintain water from underground aquifers is spearheaded by the National Ground Water Assn. (NGWA).
Rosedale filters can remove large quantities of sediment, hydrocarbons and protozoan cysts such as Giardia and Cryptosporidium, and are ideal for groundwater remediation and environmental concerns. They feature high flow rates and dirt-holding capacities, and are easily disposed of by incineration or at solid waste landfills.
Report details High Plains Aquifer groundwater level changes from 1950 to 2011 and 2009 to 2011
Delegation to India seeks to increase collaboration with Indian professionals, organizations
Kevin McCray, CAE, CEO of the National Ground Water Assn., will be leading an overseas cultural and professional exchange opportunity in September 2013.
People to People Citizen Ambassador Programs is coordinating a delegation of water resource professionals who will travel to Delhi, Jaipur and Agra, India, from Sept. 22 to 30.
Data from gravity-measuring satellites show rapid loss of freshwater reserves during the past decade
Scientists at the University of California at Irvine (UC Irvine); NASA's Goddard Space Flight Center in Greenbelt, Md.; and the National Center for Atmospheric Research in Boulder, Colo., found during a seven-year period beginning in 2003, parts of Turkey, Syria, Iraq and Iran along the Tigris and Euphrates river basins lost 117 million acre ft (144 cu km) of their total stored freshwater. That is almost the amount of water in the Dead Sea. The researchers attribute about 60% of the loss to pumping of groundwater from underground reservoirs.
High concentrations of fumigants detected in about 10% of the Madera County, Calif., aquifer system
Arsenic, uranium, fumigants and nitrate were detected at high concentrations in untreated groundwater at depths in the aquifer system typically used for public water supply in the Madera County region of California’s San Joaquin Valley.
EAD monitors groundwater selling to protect the groundwater supply against depletion and pollution
The Environment Agency - Abu Dhabi (EAD) has called upon farm, landowners and contractors to cease the drilling of wells without a permit, and the illegal selling of groundwater. EAD has reaffirmed that it will be taking all necessary legal measures against violators, in accordance with the stipulations of Law No. 6 of 2006. EAD is the government entity mandated with the implementation of this law, which regulates well drilling and other related activities.
Geology, wells, pumping contribute to groundwater level declines
Geologic barriers, the intermixing of water between aquifers through wells, and groundwater pumping contribute to the pattern of declines of groundwater levels in the Columbia Plateau, according to a report published by the U.S. Geological Survey.
Groundwater from the 44,000-sq-mile Columbia Plateau Regional Aquifer, a system in decline since the 1970s, is a critical resource for the nearly 1.3 million people in Idaho, Oregon and Washington. It also provides irrigation water for the region’s estimated $6-billion-per-year agriculture industry.
Summit to feature more than 190 presenters, 32 platform presentations and 25 posters
The 2013 National Ground Water Assn. (NGWA) Summit — the national and international conference on groundwater taking place April 28 to May 2 in San Antonio — features an agenda covering "everything groundwater," from availability and the impacts on it from hydraulic fracturing to global issues such as sustainability, quality and remediation.
Held annually, the NGWA Summit is now in its ninth year. More than 190 presenters are expected, who will offer 32 platform presentations and 25 posters in nine topic areas:
