  • Decontaminating Groundwater Sampling Devices

    These studies are the second part of a two year project that examines decontaminating groundwater sampling devices. In the first year, the efficiency of various decontamination protocols was tested using small test pieces of materials that are commonly used in groundwater sampling devices. Those tests showed that a hot detergent wash and rinse followed by hot air drying (105°C) was the most ...

  • Technical protocol for evaluating natural attenuation of chlorinated solvents in ground water

    The U.S. Environmental Protection Agency is charged by Congress with protecting the Nation’s land, air, and water resources. Under a mandate of national environmental laws, the Agency strives to formulate and implement actions leading to a compatible balance between human activities and the ability of natural systems to support and nurture life. To meet these mandates, EPA’s research ...

  • Evaluation of a bench-scale membrane fouling protocol to determine fouling propensities of membranes during full-scale water reuse applications

    There is increasing interest in recycling wastewater effluents for augmentation of existing water supplies. The treatment of wastewater effluents by an integrated membrane system, such as microfiltration pre-treatment followed by reverse osmosis, is the industry standard for groundwater recharge or reservoir augmentation projects. Membrane fouling, especially effluent organic matter fouling, is a ...

  • The impact of intentional stormwater infiltration on soil and groundwater

    ABSTRACTStormwater infiltration is a principle which is more and more utilized on urban sites in France. However, given the characteristics of urban surfaces, and notably the amounts of the different pollutants that stormwater is likely to contain, it is important to try to assess the impact of intentional stormwater infiltration systems on the soil, and on groundwater. To try to answer that ...

  • 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 ...

  • A new no-purge, non-displacement groundwater sampler

    What Is It? The HydraSleeve sampler is designed to collect representative water samples from monitoring wells without purging. The disposable sampler collects a discreet sample from only the 'fresh formation' water in the screened interval of the well. It is fast, inexpensive, simple to use, generates no purge water and collects a sample suitable for all analytical parameters. Why It Works The ...

  • Bioremediation of Nitrochlorobenzene, Nitroaniline, Chloroaniline, and Other Organics in Groundwater.

    ABSTRACT: The uppermost aquifer beneath a chemical plant contains residual concentrations of o-nitrochlorobenzene from a tank car spill, as well as other plant-related organic compounds of concern (COC), including 2-nitroaniline and o-chloroaniline. The aquifer consists of low permeability clays and silts, and produces only a few gallons of groundwater per day from a shallow ...

  • Maximizing Recycled Water Recharge in the Chino Groundwater Basin, California

    The Chino Basin Groundwater Recharge Project is a comprehensive water supply project that includes maximizing recycled water recharge. This paper focuses on critical components, challenges, and successes of the start-up process of recycled water recharge operations that are enabling Inland Empire Utilities Agency (IEUA) to maximize recharge recycled water. It will also present results of the ...

  • Addressing contaminated groundwater with organic mulch permeable reactive barriers

    Organic mulch consists of insoluble carbon biopolymers that are enzymatically hydrolyzed during decomposition to release aqueous total organic carbon (TOC). The released TOC is utilized by microorganisms as an electron donor to transform electrophilic contaminants via reductive pathways. Over the last decade, organic mulch permeable reactive barriers (PRBs), or biowalls, have received increased ...


  • Determination of Groundwater Quality Index of a Highland Village of Kerala (India) Using Geographical Information System

    In this study, the authors’ goal was to understand the groundwater quality of Nedumkandam panchayat by an integrated approach of traditional water quality analysis and Geographical Information Systems (GIS). Fourteen wells were identified from the study area and samples were collected and analyzed using standard protocols (American Public Health Association, 1998). Parameters analyzed include pH, ...

  • Effective dose owing to dissolved 222Rn in potable water of coastal Karnataka in the southwest coast of India

    This paper discusses the results of the systematic measurement of activity concentration of 222Rn in groundwater and surface water samples of two major rivers of coastal Karnataka, namely, Kali and Sharavathi. Water radon concentrations were measured using an Alpha Guard PQ2000Pro (Genitron GmbH) equipped with an appropriate unit (AquaKIT), following a protocol proposed by the manufacturer. ...

  • Interpretation of aged sorption studies for pesticides and their use in EU regulatory leaching assessments

    First‐tier regulatory exposure assessments for pesticides assume that pesticide sorption is instantaneous and fully reversible. In EU regulatory guidance, an increase in sorption over time (‘aged sorption’) can be considered at the higher tier to refine predicted environmental concentrations in groundwater. Research commissioned by the UK Chemicals Regulation Directorate (CRD), funded by ...

  • Landfill site improvement condition for PPC permit

    The installation is a landfill site licensed for the disposal of inert waste. It lies in a potentially sensitive location on the flood plain of the River Great Ouse, near Milton Keynes and it is therefore important to the client to ensure good environmental monitoring is undertaken. The site is divided into two sections, (the north western area and the south eastern area) by the River Great Ouse, ...

  • Risks from Renegade Nanoparticles during field deployments within NanoRem

    The aim of NanoRem is to support and develop the appropriate use of nanotechnology for contaminated soil and groundwater remediation. NanoRem focuses on facilitating practical, economic and exploitable nanotechnology for in-situ remediation. This can only be achieved in parallel with a comprehensive understanding of the environmental risk-benefit balance for the use of nanoparticles (NPs). One ...

  • Carbon offsets from organic waste conversion projects

    The Climate Act ion Reserve (the Reserve) has long had a protocol to give credit for the capture and destruction of methane emissions from organic waste in landfills, but they have now opened up the possibility of credits for projects that prevent that waste from entering landfills in the first place. In October 2009, the Reserve adopted the Organic Waste Digestion Project Protocol, covering both ...

  • Tools for assessing sea level rise vulnerability

    Increasing sea level has the potential to place important infrastructure we rely on every day at risk, yet we lack good data to make decisions on what to do, when, and with what priority. The objectives of the research were to develop a method for estimating the time scales for various increments of sea level rise (SLR) throughout the 21st century, develop an accurate methodology for predicting ...

  • Comparison of Monitoring Approaches for Selected Priority Pollutants in Surface Water

    1 AbstractLaboratories from seven EU Member States under the coordination of the Joint Research Centre and in collaboration with the Provincia di Ferrara participated in a technical on-site project during which sampling and analytical methodologies for chemical monitoring according to proposed WFD provisions have been compared. Laboratories had been invited to take samples from a river according ...


  • The Role of Soil Moisture on our Climate, Weather and Global Warming

    Global warming is a topic that has received much attention in the media, especially during the hot days of summer. The process by which carbon dioxide (CO 2) in the atmosphere prevents the escape of thermal energy into outer space is known as the green house effect. The higher the carbon dioxide levels in the atmosphere the less thermal energy that can escape thus an increasing global ...
