  • Analysis of Hydrologic Data to Evaluate Phytoremediation System Performance

    Abstract A long-term environmental monitoring program is providing hydrologic data that demonstrates poplar trees are influencing groundwater flow at the J-Field site, Aberdeen Proving Ground, Maryland. Advanced data collection and analyses techniques have enabled researchers to construct a water budget for the study area and to estimate the amount of groundwater the trees are transpiring on a ...

  • Insuring water: a practical risk management option in water-scarce and drought-prone regions?

    Recurrent water deficits in various arid and semi-arid Mediterranean basins are largely covered by illegal groundwater abstractions uncontrolled by the water authorities. Aquifers thus play the role of buffer stocks and are used by farmers as a reliable, although informal, insurance system. This has led to continuous groundwater depletion and increased scarcity and drought risk over the last few ...

  • Wastewater reclamation and reuse in Europe: a model-based potential estimation

    ABSTRACTThe basic aim of this paper is to present an approach to quantitatively assess the potential of municipal wastewater reclamation and reuse in a European context. The model developed is based on the analysis and interrelation of water management data like water availability, water demand and treated effluent. In conjunction with information about the current status of wastewater reuse ...

  • In Situ Bioremediation of Chlorinated Solvents

    ABSTRACT: In situ bioremediation is ongoing at a former manufacturing facility in Portland, Oregon.  Shallow groundwater at the site was impacted by chlorinated solvents, primarily trichloroethene and degradation products cis-1,2-dichloroethene and vinyl chloride.  In situ chemical oxidation treatment was completed in 2003 via the injection of sodium permanganate in source ...

  • Simulation of heavy metal pollution from stormwater infiltration through a porous pavement with reservoir structure

    ABSTRACTA laboratory experiment was set up to examine the ability of porous asphalt to retain metallic pollution. The results obtained confirm the retention of metals (Pb, Cu, Cd, Zn) by clogging particles, and a decrease in lead concentration can be observed in infiltrated runoff water. Moreover, the simulation of heavy metal transfer into the soil was carried out using the mathematical model ...

  • 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 ...

  • Synergistic Treatment of BTEX Compounds Using Oxidation and Free Radical Chemistries

    ABSTRACT: In an unusual delivery process, prompted by the historical in-situ delivery via permanent points, the unconventional introduction of a remedial solution to the groundwater using numerous pits effectively overcame site specific obstacles. A two phase program effectively at the site in Saint Augustine, Florida, introduced the remedial chemicals sodium persulfate, hydrogen peroxide ...

  • Enhanced Bioremediation of Tetrachloroethene in Central Indiana Glacial Till

    ABSTRACT: The goal of this project is remediation of soil and groundwater impacted by tetrachloroethene (PCE) that infiltrated the vadose and uppermost saturated zone below an active dry cleaning facility in central Indiana. PCE was released and transported to depths less than five meters via the primary porosity of thin sand and silt stringers and via secondary porosity of fractures in lodgment ...

  • NEW GROUNDERWATER REPORT PREPARED FOR KALGOORLIE CONSOLIDATED GOLD MINES(KCGM) IN WESTERN AUSTRALIA

    For many of our clients the impact of water abstraction and use is an element of their operation which requires long term monitoring and analysis. Results are often compared to baseline data so that impact of operations can be understood and, if necessary, modified. This is frequently an arduous task with some of our clients having more than a 100 boreholes which are regularly monitored. This ...

  • Skaneateles Lake Demonstration Project

     ABSTRACT The Skaneateles Lake Demonstration Project was established to demonstrate the use of commercially available alternative onsite wastewater treatment technologies in the Skaneateles Lake watershed to protect public health, maintain drinking water quality, and sustain the environment. Alternative onsite wastewater ...

  • Assessment of public perception regarding wastewater reuse

    ABSTRACTA descriptive-correlational study was recently conducted in a four county metropolitan area in the southeast United States (US) as part of a collaborative effort between nursing and environmental engineering researchers. The purpose of the study was to assess attitudes, knowledge and information sources concerning wastewater reuse and evaluate the results with respect to population ...

  • Bioslurping - Technology Overview

    ABSTRACT Bioslurping involves the simultaneous application of vacuum enhanced extraction/recovery, vapor extraction, and bioventing to address LNAPL contamination. Vacuum extraction/recovery is used to remove free product along with some groundwater, vapor extrac tion is used to remove high volatility vapors from the vadose zone, and bioventing is used to enhance aerobic biodegradation in the ...

  • Lessons Learned from a Dual-Phase Extraction Field Application

    ABSTRACT A field-scale Dual-Phase Extraction (DPE) system was installed and operated at the Pinellas Science, Technology, and Research (STAR) Center, formerly the U.S. Department of Energy (DOE) Pinellas Plant, in Largo, Florida, from August 1997 through September 1999. The goal of applying the DPE system was to enhance the pump-and-treat remediation of volatile organic compounds (VOCs) ...

  • Modeling the dynamics of the freshwater-saltwater interface in response to construction activities at a coastal site

    Abstract: A numerical model was developed to evaluate the response of groundwater flow and the fresh-saltwater interface in relation to the construction of a particle accelerator at the coastal plain of Tokaimura, Japan. Undisturbed conditions were initially simulated and validated against field observations as a prerequisite for the analysis of predictive scenarios. Groundwater heads 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 ...

  • Subsurface iron and arsenic removal: low-cost technology for community-based water supply in Bangladesh

    The principle of subsurface or in situ iron and arsenic removal is that aerated water is periodically injected into an anoxic aquifer through a tube well, displacing groundwater containing Fe(II). An oxidation zone is created around the tube well where Fe(II) is oxidised. The freshly formed iron hydroxide surfaces provide new sorption sites for soluble Fe(II) and arsenic. The system's efficiency ...

  • Water Rights

    The term "water rights" refers to the right (formal or informal entitlement) of a user to use water from a water source, e.g., a river, stream, pond or source of groundwater. In areas with plentiful water and few users, such systems are generally not complicated or contentious. In other areas, especially arid areas where irrigation is practiced, such systems are often the source of conflict, both ...
