Inorganic elements detected at high concentrations in 35% of region's untreated groundwater
Inorganic elements — arsenic, boron, fluoride and five others — were detected at high concentrations in 35% of untreated groundwater used for public water supply in the desert region of Southern California in a recent study by the U.S. Geological Survey (USGS). In contrast, human-made organic chemical constituents and nitrate were found at high concentrations in less than 1% of the desert region’s aquifers.
On Sept. 22, 2011, TOPS Veterinary Rehabilitation in Grayslake, Ill., initiated a pilot test to study the effectiveness of HydroFlow’s water conditioning technology on its canine therapy pools. TOPS is in the business of veterinary rehabilitation, and one of the treatment options it often employs is hydro-treadmill therapy. The facility has two 1,000-gal therapy pools supported by a large, pool-sized sand filtration system, a dual-speed filtration pump and a booster pump for the jets.

Amendment changes the remedy for soil and groundwater contamination at 10th Street Site
The U.S. Environmental Protection Agency (EPA) Region 7 has issued an amendment to the Record of Decision (ROD) for the 10th Street Superfund Site in Columbus, Neb. EPA signed the ROD for the site in February 1995 to address groundwater contamination. The selected remedy for the 1995 ROD was sampling of municipal and monitoring wells and institutional controls to limit exposure to contamination from the site.
Site activities in 2000 and 2001 led to a final ROD issued in 2005. The final ROD selected the following remedies:
The company consolidates headquarters and leadership
Layne Christensen Co. announced that its board of directors has approved the relocation of its global corporate headquarters from Mission Woods, Kan., to The Woodlands, a suburb of Houston. The move is expected to commence in spring 2013 and be completed by winter 2013.
The move will involve most executive positions in Layne's corporate leadership, as well as certain other management and staff positions. Most senior executives from Layne's six divisions will ultimately consolidate into the Houston headquarters.
About 1.7 billion people live in areas where groundwater is used more quickly than it can be replenished
Groundwater supplies water to billions of people and is important for agricultural irrigation and the health of ecosystems. Water resource assessments tend to focus on surface water, but there is increasing concern about the depletion of groundwater. Although groundwater stored in aquifers is naturally renewed, shortages can occur when it is removed more quickly than it is recharged. In order to devise appropriate management strategies and communicate the issue to the public, it is necessary to understand the extent of the problem and identify locations of particular concern.
Meeting to feature more than 300 exhibitors and more than 70 hours of educational offerings
The world’s largest gathering of groundwater professionals has inundated the Las Vegas Convention Center for the 64th National Ground Water Assn. (NGWA) Expo and Annual Meeting.

Artists Against Fracking aims to make the moratorium on fracking in New York permanent
"Governor Cuomo: Imagine There's No Fracking," reads a large billboard up last week on New York's Major Deegan Expressway, a route often used by New York Gov. Andrew M. Cuomo.
“Our message is simple: We want Gov. Cuomo to imagine and guarantee a New York free of the fracking threat to our water, air, beautiful landscapes and climate,” said Yoko Ono, who designed and purchased the billboard space. “Every time New Yorkers pass this billboard, we also want them to imagine a truly clean energy future, not fracking.”
Many regions across the U.S. are experiencing drought conditions, and in the past few years Texas has been especially hard hit. Water Quality Products Managing Editor Kate Cline spoke with Bob Boerner, president of Culligan Southwest Inc., to find out how the drought is affecting water quality in the state.
Kate Cline: What is the status of the drought in Texas? What is the outlook?
Groundwater provides a valuable source of drinking water for millions of people across the U.S. But as new contaminants are discovered and droughts continue to worsen, resulting in depleted aquifers, it is increasingly important to monitor the quantity and quality of available groundwater. The U.S. Geological Survey (USGS) recently updated Water Quality Products on the status of groundwater quality in the U.S.
What is the role of the USGS in surveying and monitoring groundwater quality and availability in the U.S.?
U.S. groundwater faces increasing contamination & overuse
The source for drinking water is an important consideration when determining which water quality tests to run. Groundwater sources, especially private wells that are not tested on a regular basis, are susceptible to various naturally occurring and manmade contaminants.
The depth of a well is an important factor when determining which contaminants are present in groundwater sources. Shallow wells are more vulnerable to surface contaminants, such as gasoline from a spill, because the contaminant has less distance to travel.
