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:
Construction and use of Pearce Creek has degraded groundwater quality close to the facility
The construction and subsequent use of the Pearce Creek Dredge Material Containment Area, combined with pre-existing natural conditions, has degraded the quality of groundwater close to the facility, according to a recent U.S. Geological Survey (USGS) study.
Depth of McLaughlin Crater once allowed underground water to flow into the crater's interior
A NASA spacecraft is providing new evidence of a wet underground environment on Mars that adds to an increasingly complex picture of the red planet's early evolution.
The new information comes from researchers analyzing spectrometer data from NASA's Mars Reconnaissance Orbiter (MRO), which looked down on the floor of McLaughlin Crater. The Martian crater is 57 miles in diameter and 1.4 miles deep. McLaughlin's depth apparently once allowed underground water, which otherwise would have stayed hidden, to flow into the crater's interior.
Bill Weathersby of Water Energy Solutions to speak at the 14th Changing Face of Water Rights
The State Bar of Texas is offering the 14th Changing Face of Water Rights, a continuing legal education course at the Hyatt Hill Country Resort in San Antonio, Feb. 21 to 22. Bill Weathersby, CEO of Energy Water Solutions, a Texas-based oilfield produced water and "frack" water recycling firm, is an invited energy industry speaker. He will speak alongside elected thought leaders on water conservation, and legal and water policy experts from several agencies and professional service firms.
MIOX awarded research grant to commercialize onsite generated AOP chemistry
MIOX Corp. has received a Technology Enhancement for Commercial Partnerships (TECP) award from the Small Business Innovation Research (SBIR) program of the National Science Foundation (NSF) in the amount of $100,000. This research grant allows MIOX to move forward in the commercialization of lower cost advanced oxidation process (AOP) technology for groundwater remediation and water reuse applications.
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:
