  • Characterising aquifer treatment for pathogens in managed aquifer recharge

    In this study the value of subsurface treatment of urban stormwater during Aquifer Storage Transfer Recovery (ASTR) is characterised using quantitative microbial risk assessment (QMRA) methodology. The ASTR project utilizes a multi-barrier treatment train to treat urban stormwater but to date the role of the aquifer has not been quantified. In this study it was estimated that the aquifer barrier ...

  • A GIS-based methodology to delineate aquifer recharge areas

    A GIS-based methodology to delineate risk areas for contamination of groundwater resources is presented by identifying recharge conditions to the aquifer. Identifying the recharge areas is based upon surface and subsurface geologic conditions that may control the risk of potential oil spill contaminants into the aquifer. This study uses the Chicot aquifer system in southwest Louisiana as a pilot ...

  • 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 ...

  • Modeling the groundwater recharge in karst aquifers by using a reservoir model

    The estimation of the groundwater recharge in a karstic system becomes an important challenge due to the great hydrodynamic variability in both time and space. This paper proposes a two reservoir conceptual model to simulate inflow into both the conduit system and the fissure network system based on the analysis of the spring hydrograph. The structure of the model and the governing equations are ...

  • 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 ...

  • 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 ...

  • Impact on Gaza aquifer from recharge with partially treated wastewater

    The Gaza Strip suffers from high pressure imposed on its water resources. There is a deficit of about 50 mm3 every year, which has led to a declination of groundwater level and deterioration of groundwater quality. New water resources are sought to fulfil the water deficit; among them is the artificial recharge of treated wastewater to groundwater. The impact of recharging partially treated ...

  • Managed aquifer recharge: rediscovering nature as a leading edge technology

    Use of Managed Aquifer Recharge (MAR) has rapidly increased in Australia, USA, and Europe in recent years as an efficient means of recycling stormwater or treated sewage effluent for non-potable and indirect potable reuse in urban and rural areas. Yet aquifers have been relied on knowingly for water storage and unwittingly for water treatment for millennia. Hence if ‘leading edge’ is defined as ...

  • 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 ...

  • Relevance of hydrological parameters in artificial recharge sites selection and assessment in a granitic aquifer

    Due to increasing demand of groundwater and indiscriminant pumping, groundwater levels have been declined beyond economic levels and the natural recharge is not enough. Thus enhancing recharge to the groundwater system through artificial means has been evident. Depending on the situation, a variety of methods have been in practice but assessing their efficacy as well as optimal site selection has ...

  • 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 ...

  • Pharmaceutical removal during managed aquifer recharge with pretreatment by advanced oxidation

    Organic micropollutants (OMPs) are detected in sources for drinking water and treatment possibilities are investigated. Innovative removal technologies are available such as membrane filtration and advanced oxidation, but also biological treatment should be considered. By combining an advanced oxidation process with managed aquifer recharge (MAR), two complementary processes are expected to ...

  • 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 ...

  • Application of 3D-fluorescence/PARAFAC to monitor the performance of managed aquifer recharge facilities

    3D-fluorescence spectroscopy was used as a monitoring tool to describe the fate and transport of dissolved organic matter (DOM) during groundwater recharge using recycled water, imported water, and stormwater at a managed aquifer recharge site in California. The study was supplemented by analysis of conservative wastewater-derived trace organic chemicals using liquid chromatography coupled ...

  • Recharge areas and geochemical evolution of groundwater in an alluvial aquifer system in the Sultanate of Oman

    A regional hydrogeochemical model was developed to evaluate the geochemical evolution of different groundwaters in an alluvial aquifer system in the Interior of Oman. In combination with environmental isotopes the model is able to extract qualitative and quantitative information about recharge, groundwater flow paths and hydraulic connections between different aquifers. The main source of water ...

  • Quality assessment of deep-well recharge applications in the Netherlands

    Artificial recharge of aquifers can be performed for various purposes and under varying hydrogeological conditions. We present an overview of deep-well recharge applications which have taken place in the Netherlands over the last two decades. We present the purpose of each application, the issues which had to be resolved, the preventive measures which were taken to improve performance and the ...
