thumbnail new Groundwater Potential Mapped in the Susquehanna River Valley, New York –USGS, in cooperation with New York State Department of Environmental Conservation, assessed and mapped a variety of aquifer types and described their current use and potential as groundwater sources in the valley-fill aquifer along a 32 mile reach of the Susquehanna River valley and adjacent areas was evaluated in eastern Broome and southeastern Chenango Counties, New York. The study area includes part of south-central New York that has substantial natural gas potential in the underlying Marcellus and Utica shale formations. Findings help managers make decisions on future groundwater use and protection. (Press release; Report and interactive map)


thumbnail new New Groundwater Model Used to Manage Water Resources around Wichita, Kansas –USGS, in cooperation with the City of Wichita, developed a groundwater model to accurately track available water, account for water that is artificially recharged into the aquifer, and monitor the movement of chloride. The study began in 2009 to determine groundwater flow in the Wichita well field area, and chloride transport from the Arkansas River and Burrton oil field. The model helps to determine effects on groundwater from changes in well pumping, rainfall, and streamflow. Results from this study are available (Report; Press release)


thumbnail new Groundwater Pumping Continues to Reduce Streamflow in the Verde Valley, Central Arizona –USGS, in cooperation with the Verde River Basin Partnership and the Town of Clarkdale, assessed streamflow of the Verde River—one of Arizona's largest streams with year-round flow, showing declines from 1910 to 2005 as the result of human stresses, primarily groundwater pumping. The study's findings suggest that streamflow reductions will continue and may increase in the future. (Press release; Report)


thumbnail new Declines in Groundwater Levels in the Columbia Plateau Regional Aquifer, Washington, Oregon, and Idaho –The USGS Groundwater Resources Program and Cooperative Water Program, in cooperation with the Oregon Water Resources Department, compiled and analyzed well information and groundwater levels collected by USGS and seven other organizations. The data were used to develop a simple linear groundwater-level trends map of the aquifers of the Columbia River Basalt Groups for 1968-2009. Geologic barriers, the intermixing of water between aquifers through wells, and groundwater pumping contribute to a pattern of declines of groundwater levels of the Columbia Plateau (Press release; Report)


thumbnail new Streamflow Information Now Available for Ungaged Streams in Pennsylvania –USGS, in cooperation with the Pennsylvania Department of Environmental Protection, the Susquehanna River Basin Commission, and The Nature Conservancy, developed the Baseline Streamflow Estimator, called "BaSE," which provides users with estimated daily mean streamflow, minimally altered by human activities, for locations on Pennsylvania streams that don’t have streamgages. Water-resource managers use daily mean streamflow to evaluate withdrawal, allocation, and wastewater permit applications and to assess the health of the Commonwealth's streams.  Historically, it has been difficult, costly, and time intensive to estimate daily mean streamflow for stream locations that were not gaged or monitored. BaSE allows users to estimate daily mean streamflow values and daily hydrographs by entering a few basic basin characteristics in an easy-to-use tool.  The output is a summary spreadsheet, containing information about the location of interest, including daily mean streamflow for every day from 1960 to 2008. (Technical announcement; Report; BaSE tool and supporting documentation)


thumbnail new Water Quality in the Fayetteville Shale Gas-Production Area, North-Central Arkansas –USGS, in cooperation with the Arkansas Natural Resources Commission, Arkansas Oil and Gas Commission, Duke University, Faulkner County, Shirley Community Development Corporation, and the University of Arkansas at Fayetteville, examined water quality in 127 shallow domestic wells in the Fayetteville Shale natural gas production area of Arkansas and found no groundwater contamination associated with gas production. Scientists analyzed water-quality data from samples taken in Van Buren and Faulkner counties in 2011, focusing on chloride concentrations from 127 wells and methane concentrations and carbon isotope ratios from a subsample of 51 wells. Chloride is a naturally occurring ion that is found at elevated levels in waters associated with gas production. Chloride moves easily through groundwater without reacting with other ions or compounds in solution, which thereby makes it a good indicator of whether chemicals used during hydraulic fracturing are reaching groundwater. In this case, the chloride concentrations from this study were not higher than samples taken from nearby areas from 1951 through 1983. Methane is the primary component of natural gas, but also can be found naturally in shallow shale formations in the Fayetteville Shale area that are used as sources of water for domestic supplies. What methane was found in the water, taken from domestic wells, was either naturally occurring, or could not be attributed to natural gas production activities. (Full report; Press release)
