  • Tailings paste disposal – more than water recovery

    The minerals industry has faced increasing pressures in recent years in the management of tailings streams. Environmental, economic and other factors have led many minerals producers to explore the technology of making and using “paste.” With the increasing number of installations worldwide, this technology has proved to not only be industry accepted, but economically advantageous. ...

  • Case study -Norfolk County Council tackle groundwater contamination with low-flow

    Geotech low flow groundwater analysis equipment has enabled quick and easy access to samples at 2m intervals down a 28m screen in deep boreholes. Elizabeth Guilford of Norfolk County Council hired the low flow kit from Geotech and used it on a Norfolk CC landfill where leachate contamination of groundwater was suspected. Samples taken at 2m intervals close to elevation of the suspected ...

  • Study of groundwater using visual MODFLOW in the Manas River Basin, China

    For effective groundwater management of a basin, it is essential that a careful water balance study be carried out. A three-dimensional transient-state finite difference groundwater flow model is used to quantify the groundwater fluxes and analyze the dynamic changes of groundwater level. After monitoring groundwater levels for 43 typical observation wells through a simulation study of the ...

  • Performance assessment of low-order versus high-order numerical schemes in the numerical simulation of aquifer flow

    Numerical methods have been widely used to simulate transient groundwater flow induced by pumping wells in geometrically and mathematically complex systems. However, flow and transport simulation using low-order numerical methods can be computationally expensive with a low rate of convergence in multi-scale problems where fine spatial discretization is required to ensure stability and ...

  • New study assesses the global volume and distribution of “modern” groundwater

    Groundwater has long been an important resource for spraying, drinking water, energy production and more, but getting a clear picture of how much is available and being recharged over time has been a challenge. Now an international group of hydrologists led by Tom Gleeson, engineering professor at the ...

  • Determinants of water purchases by pistachio producers in an informal groundwater market: a case study from Iran

    Market-based water allocation systems have the potential to ensure that scarce water will flow to the user who earns the highest marginal value from that water. However, the number of recorded instances where water supply problems are solved by market-based systems remains limited. This study attempts to identify the decisive factors that motivate farmers’ participation in informal spot water ...

  • Cost saving case study using a calcium sulphate specific antiscalant

    Abstract Extensive extraction from aquifers often leads to deterioration in water quality. This is usually seen as an increase in the soluble salt levels which, over time, has a detrimental effect on membrane performance. A limiting factor in the efficiency of membrane operation is the recovery rate that can be achieved, particularly with ‘brackish’ water operation. A high ...

  • ROMAG stainless steel installations for the largest groundwater pumping station in Switzerland

    The pumping station in Uetendorf near Thun, Switzerland, went into operation in March 2014, and pumps 25,000 l/min of water from a depth of 19 m. 40% of the drinking water in Switzerland is pumped out of groundwater streams. To guarantee an adequate long-term supply of drinking water in the greater region around the city of Thun, the public company WARET (Wasserversorgung Region Thun AG) was ...

  • Development of a risk-based approach for better protection of drinking water catchments in Flanders (Belgium)

    Around 70% of the drinking water produced by De Watergroep (a Belgian public water company) is extracted from 83 groundwater pumping sites. To control the risks that endanger the drinking water supply and for the groundwater extracted to be as pure as possible, a risk-based approach for the protection of the catchment areas is developed, as part of the water safety plans. The approach ...

  • Managed aquifer recharge: the widening gap between law and policy in India

    The past decade has witnessed discussions on various options to overcome groundwater depletion, such as rainwater harvesting (RWH) and ‘artificial recharge’ methods. This paper addresses law and policy issues relating to managed aquifer recharge (MAR). Based on an analysis of the National Water Policy of India and water polices and laws of the Indian states, a concrete case study, namely ...

  • Sharpening Your Way to Better Groundwater Models

    There is a well-known fable about a wood cutter who was hired by a timber merchant to cut down trees. This well sought-after job paid well and had excellent working conditions. The wood cutter wanted to succeed in his new job so the first day he worked hard and cut down 18 trees. Determined to do even better on the second day, the wood cutter tried harder but only cut down 15 trees. Day after day ...

  • Monitoring groundwater resources for Municipalities - Case Study

    Background The City of Tucson is located in the Sonoran Desert in southwest United States (U.S.), approximately 100 km north of the Mexico-U.S. border. Tucson Water operates more than 215 groundwater wells, covering more than 300 square miles, providing more than 37 billion gallons (140 million m3) of potable water to its 730,000 inhabitants each year. The region receives only 12 inches of ...

  • 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 ...

  • Groundwater management in China

    After introducing groundwater development and other issues, the paper analyzes China's groundwater management system and its problems, and provides suggestions for improving the system. Increasing water demand since the 1970s has resulted in severe groundwater overdraft, water level decline and water quality degradation in China, but the current management system is not able to provide an ...

  • Water resources and the potential of brackish groundwater extraction in Egypt: a review

    A review of water resources in Egypt indicates that Nile water is fully utilized and the available quantity could potentially decrease by approximately 19% due to proposed water usage by neighboring countries. Seawater desalination and groundwater extraction are the only options to increase Egypt's water supply. The extraction and desalination of brackish groundwater is suggested ...
