  • How Reliable Are Your Groundwater Level Measurements

    Over the past few years, Eijkelkamp Soil & Water has gained extensive experience in the management of groundwater level measurement networks. This experience also serves as a foundation for our ongoing efforts to develop and enhance the collected data. For example, in the course of our activities, we have observed a growing discrepancy between manually-collected measurement data and ...

  • Analysis of TNT and RDX in groundwater

    MATRIX: Water ANALYTE: TNT and RDX LIMIT OF DETECTION: TNT 1 ppb (mg/L), RDX: 5 ppb (mg/L) BACKGROUND: This application describes a field screening method for determining TNT and RDX concentrations in water. The method uses solid phase extraction to remove and preconcentrate the analytes from water. In the method, a 2 ...


  • Who Owns Groundwater?

    California’s drought underscores the need to improve how the state - and the rest of us - divvy up a resource in demand. Grapevines march across wires strung along rolling hills, their little trunks improbably supporting heavy black fruit. Cindy Steinbeck’s family has been farming this land since 1920. They grow Zinfandel, Viognier, Cabernet, Merlot, and Petite Syrah grapes but are ...

  • Spatio-temporal assessment of groundwater level and quality in urban coastal city Puri, India

    Puri city is situated on the shoreline of Bay of Bengal and groundwater is the only source available to meet the city water supply mainly from two demarcated water fields. Due to the anthropogenic activities and absence of sewerage system, groundwater quality is deteriorating through open discharges of domestic waste, open defecation, septic tanks, soak pits, contaminated water pools, unorganized ...

  • Assessment of riverside groundwater flood risk induced by high river water levels using a numerical model and monitoring data

    Large barrages have been constructed on the main rivers in South Korea to store water and mitigate fluvial flooding damage. However, the increase in water levels behind the barrages can potentially lead to a rise in groundwater levels in the riversides. The purpose of this study was to describe the effect of a barrage on groundwater levels and to test the applicability of a numerical model to ...

  • Potential impact of heterogeneity on groundwater age

    Groundwater age is an important water property used as an indicator of groundwater quality. There have been no sufficient data and measurements underground, and that problem has been mitigated by using direct simulation of groundwater age. This paper has been motivated by the work of Daniel J. Goode, defining a rather different approach. A numerical model has been developed, using the Lagrangian ...

  • New Spanish regulation on groundwater protection

    On 22 October it was issued Royal Decree 1514/2009 regulating the protection of groundwater against pollution and deterioration. The legal framework of this Royal Decree is formed by Directive 2000/60/EC (WFD) in particular Article 17, and Directive 20006/118/EC. The main objectives are to prevent or limit groundwater pollution and to establish criteria and procedures to assess their chemical ...

  • Why it’s time to elevate groundwater

    Groundwater stored in the earth’s crust underpins all our lives – the ultimate source of freshwater for billions has become victim of over-extraction and the ultimate sink for pollutants.   For too long, not enough has been done to regulate the use of this precious, on-demand resource and manage disposal of waste. If rates of groundwater depletion have tripled in the past 3 ...

  • Kenya - Groundwater governance case study

    This report presents a case study on groundwater governance in Kenya. The objectives of the study were to: (a) describe groundwater resource and socioeconomic settings for four selected aquifers; (b) describe governance arrangements for groundwater management in Kenya; and (c) identify the relevance of these arrangements for planning and implementing climate change mitigation measures. The report ...

  • The In Situ Bioremediation/Groundwater Remediation Process

    In-situ groundwater bioremediation is a technology that encourages growth and reproduction of indigenous microorganisms to enhance biodegradation of organic constituents in the saturated zone. In-situ groundwater bioremediation can effectively degrade organic constituents which are dissolved in groundwater and adsorbed onto the aquifer matrix. The Adventus In Situ Bioremediation/Groundwater ...


  • Performance-Based Measurement Systems

    Many of the Environmental Protection Agency's (EPA's) methods used to monitor air, water and soil for environmental contaminants prescribe step-by-step details on how the chemical analysis must be conducted and prohibit any deviations or variations. The EPA has recognized that monitoring equipment and technology have improved tremendously over the last few years; that environmental media do not ...

  • Modeling Leachate Contamination and Remediation of Groundwater at a Landfill Site

    Leachate contamination of an aquifer from a landfill sitewas simulated using the groundwater flow and transport model SUTRA developed by the U.S. Geological Survey. The model calibration was performed by spatially adjusting the hydraulic conductivity in order to capture the measured hydraulic head spatial variation and then by adjusting the dispersivity and porosity match the measured chloride ...

  • Effective Groundwater Monitoring Using Dedicated Pumping Tubes

    This article describes a groundwater monitoring procedure that does not require decontamination of pumping equipment, eliminates the chance of cross contamination between wells, and uses a surface pump.  Two surface pumps are described, one for water level depths less than 25 feet and one for water level depths greater than 25 feet. Install Dedicated Pumping Tubes ...

  • Groundwater Contamination Plume Remediation - Case Study

    19 CMT Multilevel Systems Successfully Installed in Challenging  A facility in Pontypool, Wales, UK was once the location of a plastic forming plant. Over time, chemicals produced through the plastic forming processes were lost into the groundwater beneath the facility, creating a large contaminant plume. Years later it was determined that the plume is ...

  • The effectiveness of arsenic remediation from groundwater in a private home

    Abstract Private wells are the source of drinking water for approximately 15% of households in the United States, but these wells are not regulated or monitored by government agencies. The well waters can contain arsenic, a known carcinogen that occurs in groundwater throughout the nation at concentrations that can exceed the Maximum Contaminant Level defined by the U.S. Environmental ...
