In groundwater remediation, Groundwater Circulation Wells (GCW) are used as an alternative to typical Pump & Treat (P&T) methods. Extraction and injection are operated in a single well with multiple isolated screened intervals, which creates a three-dimensional flow pattern (circulation cell) in the aquifer. The utility of GCW pump test data can be increased using groundwater modelling to asses...

Sandstone-hosted roll-front uranium ore deposits originate when U(VI) dissolved in groundwater is reduced and precipitated as insoluble U(IV) minerals. Groundwater redox geochemistry, aqueous complexation, and solute migration are important in leaching uranium from source rocks and transporting it in low concentrations to a chemical redox interface where it is deposited in an ore zone typically...

Water storage depletion is a worsening hydrological problem that limits agricultural production in especially arid/semi-arid regions across the globe. Quantifying water storage dynamics is critical for developing water resources management strategies that are sustainable and protective of the environment. This study uses GRACE (Gravity Recovery and Climate Experiment), GLDAS (Global Land Data A...

Deep (>300 m) subsurface hydrochemical data are important components of geological investigations of potential radioactive waste disposal sites. These data can be interpreted to yield information that supports conceptual hydrogeological models, constrains palaeohydrogeological evolution and characterises subsurface hydrochemical conditions of a site. The most important sources of these data are...

The northwest area of Shandong Province is rich in geothermal resources. As renewable energy and clean with heat water resources as a whole, more attention has been paid to it, it widely used heating, breeding, bathing other industries, good economic social benefits have achieved. In the process long-term development utilization deep groundwater, both groundwater belong resources, they are util...

Twenty one of 118 irrigation water wells in the shallow (25-30 m thick) Mississippi River Valley alluvial aquifer in the Bayou Bartholomew watershed, southeastern Arkansas had arsenic (As) concentrations (<0.5 to 77 microg/L) exceeding 10 microg/L. Sediment and groundwater samples were collected and analyzed from the sites of the highest, median, and lowest concentrations of As in groundwater i...

Groundwater is the biggest freshwater reservoir in world. More than 95% of unfrozen water comes from groundwater. Factors responsible for groundwater consumption by rice growers have been included study. For study, Purba Barddhaman district was selected purposively considering pattern agriculture and extent use state. One community development block has based on crop diversity, type irrigation,...

Horizontal drilling and hydraulic fracturing have enhanced unconventional hydrocarbon recovery but raised environmental concerns related to water quality. Because most basins targeted for shale-gas development in the USA have histories of both active and legacy petroleum extraction, confusion about the hydrogeological context of naturally occurring methane in shallow aquifers overlying shales r...
