  • The London aquifer

    The aquifer beneath London is subject to a considerable number of stresses including rising groundwater levels, abstraction sustainability, artificial recharge, saline intrusion, groundwater flooding, and the growth of ground source energy.  ESI has recently undertaken two key projects for the Environment Agency to aid the management of these pressures in a sustainable and cost effective ...

  • Identification of Naegleria fowleri in warm ground water aquifers

    Received for publication February 16, 2009. The free-living amoeba Naegleria fowleri was identified as the etiological agent of primary amoebic meningoencephalitis that caused the deaths of two children in Peoria, Arizona, in autumn of 2002. It was suspected that the source of N. fowleri was the domestic water supply, which originates from ground water sources. In this study, ground water from ...

  • Reclaimed Water Aquifer Storage and Recovery: Potential Changes in Water Quality

    Aquifer storage recovery (ASR) operations recharge and recover water through the same well or wells, creating a “bubble” of stored water that typically mixes minimally with ambient groundwater once the storage zone has been developed. Because ASR recharge water does not flow through a vadose zone and is not drawn through an aquifer to a distant point of withdrawal, changes in water quality that ...

  • Aquifer recharge for securing water resources: the experience in Llobregat river

    The Llobregat Delta Aquifer has historically been a strategic water supply resource to the Barcelona metropolitan area. The use of river water combined with the exploitation of groundwater resources during dry periods has enabled the demographic and economic growth of the Barcelona area during the last fifty years. The aquifer overexploitation has entailed the decrease of groundwater level and ...

  • Water quality management of aquifer recharge using advanced tools

    Managed aquifer recharge (MAR) with recycled water or other alternative resources is one of the most rapidly growing techniques that is viewed as a necessity in water-short areas. In order to better control health and environmental effects of MAR, this paper presents two case studies demonstrating how to improve water quality, enable reliable tracing of injected water and better control and ...

  • Abandon Well Contaminate Aquifer

    This article points out the magnitude of this urgent issue.  An abandoned well becomes an opening into an aquifer which is likely to introduce contamination.  Filling it in is a critical component of protecting the well water supply.  Click here to read the ...

  • Assessment of water qualities and evidence of seawater intrusion in a deep confined aquifer: case of the coastal Djeffara aquifer (Southern Tunisia)

    Geochemical analyses of groundwater samples from the Djeffara confined aquifer (Southern Tunisia) were performed. The distribution of saline waters was investigated to identify the origin of the groundwater contamination. The aquifer was shown to be affected by an abnormal increase in groundwater salinity. Near the recharge zone, the groundwater salinity does not exceed 2.5 g l−1 but ...

  • Managed aquifer recharge with reclaimed water: approaches to a European guidance framework

    Managed Aquifer Recharge (MAR) with reclaimed water plays a particular role in water stress mitigation, due to both the large potential benefits achieved in terms of sustainable water resources management as well as the complexity of the planning and implementation. This paper focuses on the role of policy in establishing water quality related legal frameworks that are crucial for MAR ...

  • Meeting Melbourne's future demand for water using aquifer storage and recovery

    Melbourne is one of the fastest growing cities in Australia. City West Water (CWW) has developed an Integrated Water Cycle Management (IWCM) Strategy which includes the development of aquifer storage and recovery (ASR) schemes to store recycled water and storm water to assist with meeting future growth, where these schemes can be demonstrated to be viable and cost effective. The investigation ...

  • Interconnectivity between the Superficial Aquifer and the Deep Confined Aquifers of the Gnangara Mound, Western Australia

    Perth groundwater resources are obtained from three major aquifers that occur beneath the Perth metropolitan area: the Superficial aquifer, Leederville aquifer and Yarragadee aquifer. Each aquifer has a unique seasonal water level pattern controlled by soils, geomorphology and geology. Landuse is mainly responsible for variations in recharge; however, the hydraulic properties control aquifer ...

  • Hydraulic and thermal response of groundwater–surface water exchange to flooding in an experimental aquifer

    Summary The effects of flooding on interactions between streams and shallow aquifers are poorly studied due to the unpredictable nature of flooding events. This study examines groundwater-surface water interactions in a constructed experimental meander over several simulated flood events using hydrologic and thermal monitoring. Detailed steady-state hydraulic head measurements were taken of ...

  • Bacteriological assessment of aquifer storage and recovery (ASR) water in southwest coastal Bangladesh

    Safe drinking water is scarce in southwest coastal Bangladesh. Harvested rainwater and rain-fed pond water are the main sources of drinking water for people living in this area. Both government and non-government organizations are promoting aquifer storage and recovery (ASR) schemes to provide safe drinking water for this population. This study assessed the bacteriological quality of both ...

  • Mapping of freshwater aquifers case study

    Big Pine Key, Florida The Nature Conservancy is coordinating investigations to document the physical and biological changes that will occur on small oceanic islands as a result of sea level rise. Big Pine Key, FL is one of the primary areas of investigation because of extensive previous work and that a large portion of the island is a National Wildlife Refuge and therefore not subject to ...

  • Vertical disparity in electrical conductivity of groundwater: inferring water-bearing fractures in granitic aquifer

    A detailed study was conducted in hard rock terrain for delineating water-bearing fractures using electrical conductivity (EC) logs. The EC logs of groundwater were taken both in pre- and post-monsoon seasons of the year 2001; in 25 borewells in a small granitic watershed at an interval of 1 m right from the water table (though narrow spacing wherever required) till the depth to bottom of the ...
