  • Controlling groundwater over abstraction: state policies vs local practices in the Jordan highlands

    The control of groundwater over abstraction is a vexing problem worldwide. Jordan is one of the countries facing severe water scarcity which has implemented a wide range of measures and policies over the past 20 years. While the gap between formal legal and policy frameworks and local practices on the ground is widely acknowledged, few studies investigate how local users react to state ...

  • 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 ...

  • Deep groundwater collection tenches by the bio-polymer drain method

    Introduction The installation of deep drainage trenches has long been a risk-filled and costly endeavor, conventional installation techniques involve dewatering, sheeting and shoring, and danger to personnel working in the trench from trench collapse. Recently, due to the public's concern for the environment and the need to preserve groundwater resources, there has been an increased demand ...

  • Seeking optimal groundwater pumping strategies at Pinggu District in Beijing, China

    A simulation-based fuzzy optimization method (SFOM) was proposed for regional groundwater pumping management in considering uncertainties. SFOM enhanced the traditional groundwater management models by incorporating a response matrix model (RMM) into a fuzzy chance-constrained programming (FCCP) framework. RMM was used to approximate the input–output relationship between pumping actions ...

  • Impact of Groundwater Abstractions on River Flows (IGARF)

    This project was undertaken to review the current practice for the evaluation of groundwater abstractions on river and stream flows when assessing groundwater abstraction licence applications. This research contract formed Phase I of the National Groundwater and Contaminated Land Centre’s IGARF programme. The primary objectives of the project were to present a reasoned, robust and ...

  • Natural attenuation: better than groundwater extraction?

    Monitored natural attenuation (MNA) was evaluated and implemented in May 2000 as a replacement for groundwater extraction and treatment as the long-term remedy for a chlorinated ethene plume at a Superfund site in Washington (Lehmicke et al. 2000). MNA was approved because the plume met the first two lines of evidence in EPA’s protocol on natural attenuation for chlorinated solvents (U.S. EPA ...

  • Nutrient variation in an urban lake Chain and its consequences for phytoplankton production

    In the Central Arizona–Phoenix (CAP) ecosystem, managers divert mixed stream water and groundwater to maintain an artificial lake chain in Indian Bend Wash (IBW), a historically flashy, ephemeral, desert stream. Nutrient concentrations in the CAP ecosystem's groundwater, stream water, and floodwater differ: stream water has low concentrations of both inorganic N and P, while groundwater is low in ...

  • Replacement of Expensive Groundwater Pump and Treat System Pump and Treat System with Bioremediation

    Introduction Prior operations at a former Microwave electronics facility inSunnyvale, California, resulted in tetrachloroethene (PCE), trichloroethene ( TCE), cis-1,2-dichloroethene (DCE) and vinyl chloride (VC) impacts to soil and groundwater. In 1985, a groundwater pump and treat (P&T) system was implemented to address groundwater impacts. In 1996, CDM began ...
