  • Groundwater banking: opportunities and management challenges

    Groundwater banking is the use of aquifers to store water to balance seasonal or longer-term variations in supply and demand. The large storage capacity provided by aquifers can be a valuable tool for conjunctive use of surface water and groundwater as well as other elements of integrated water resources management. Successful groundwater banking requires favorable hydrogeological conditions to ...

  • Knowledge, participation and transparency in groundwater management

    Water in sufficient amounts and quality is essential for meeting both human and ecological needs. Most water used by mankind is destined for agriculture, and demand is steadily growing. Under this pressure, water management faces significant environmental problems. In the case of groundwater, these difficulties are exacerbated by intensive, unregulated exploitation, and the spatial ...

  • Environmental Data Management for Groundwater Contamination

    ESdat environmental data management software has been used to manage and report on large datasets generated from an investigation of groundwater contamination on an industrial facility in Adelaide. ESdat was used in managing site data and the maintenance of conceptual model and time series outputs at a complex site over an extended period. Leakages of TCE and the subsequent ...

  • Swarm intelligence for groundwater management optimization

    This paper presents some simulation–optimization models for groundwater resources management. These models couple two of the most successful global optimization techniques inspired by swarm intelligence, namely particle swarm optimization (PSO) and ant colony optimization (ACO), with one of the most commonly used groundwater flow simulation code, MODFLOW. The coupled simulation–optimization ...

  • A new frontier in Texas: managing and regulating brackish groundwater

    The challenge of providing access to clean water is visible in Texas, where chronic drought coincides with increasing water demand. The 2012 Texas State Water Plan reports a 2,700 million cubic metres (MCM) gap between freshwater supply and demand in 2010, a number predicted to grow to 3,100 MCM by 2060. Due to the difficulty of reducing water demand, policy makers and water providers are ...

  • Groundwater management: a search for better policy combinations

    Excessive groundwater pumping is now a global concern. There is no panacea for this problem, which needs to be addressed through continual policy improvements based on case studies. Good examples of the diversity of groundwater management are demonstrated by the Tokyo (Japan) and Orange County Water District (OCWD, California, USA) experiences. In Tokyo, excessive groundwater pumping was ...

  • Low-Flow Purging Reduces Management of Contaminated Groundwater

    Purging a monitoring well prior to sampling removes stagnant water in the well casing and ensures collection of groundwater samples representative of formation water. Traditionally, a number of well casing volumes are removed (from three to five) and water stabilization parameters are monitored during removal of the casing volumes. Temperature, pH and specific conductance are routinely monitored ...

  • Bank filtration as managed surface-groundwater interaction

    Riverbank Filtration (RBF) is a managed surface-groundwater interaction process where surface water is induced to flow to pumping wells installed on the banks of rivers and lakes. We present the surface-groundwater interaction issues at various geomorphologic settings, from the headwaters of a river to its confluence with the oceans/lakes. In each reach, the factors for the sustainable operation ...

  • Mining wastewater management and its effects on groundwater and ecosystems

    Large-scale mining activities have a huge impact on the environment. Determination of the size of the effect and monitoring it is vital. In this study, risk assessment studies in mining areas and the effect of mining on groundwater and ecosystems were investigated. Best management practices and risk assessment steps were determined, especially in areas with huge amounts of mining wastewater. The ...

  • Managing the invisible : understanding and improving groundwater governance

    Groundwater is playing an increasingly important role in domestic, industrial and agricultural water supply. With the advent of the tube well and driven by the rapid growth of demand for agricultural and municipal water, annual global groundwater extraction has increased in recent decades from 100 km3 a year in 1950 to a current estimated use of about 800 km3 a year (Wada et al., 2010; Margat, ...

  • Soil and groundwater remediation

    At a site in northern Indiana on behalf of a multinational client, Troy Risk operated a groundwater remediation system to cleanup the source of chlorinated solvent impact to a groundwater aquifer system. Prior to 1988, the site was occupied by a manufacturing facility. In March 1995, chlorinated volatile compounds (CVOCs) were detected pursuant to due diligence for real estate refinancing. From ...

  • Groundwater arsenic in Chimaltenango, Guatemala

    In the Municipality of Chimaltenango, Guatemala, we sampled groundwater for total inorganic arsenic. In total, 42 samples were collected from 27 (43.5%) of the 62 wells in the municipality, with sites chosen to achieve spatial representation throughout the municipality. Samples were collected from household faucets used for drinking water, and sent to the USA for analysis. The only site ...

  • Who Owns Groundwater?

    California’s drought underscores the need to improve how the state - and the rest of us - divvy up a resource in demand. Grapevines march across wires strung along rolling hills, their little trunks improbably supporting heavy black fruit. Cindy Steinbeck’s family has been farming this land since 1920. They grow Zinfandel, Viognier, Cabernet, Merlot, and Petite Syrah grapes but are ...
