  • 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 ...

  • Biobarriers for groundwater treatment: a review

    Biobarriers (BBs) are a new type of in situ technology for the remediation of contaminated groundwater. In recent years, this remediation technique has been more and more used in place of traditional Pump & Treat systems or other in situ technologies both in the USA and Europe. This work reviews the main experiences of BBs. The literature contains reports about tests ...

  • 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 ...


  • Modelling of groundwater flow and heat transport

    Client: Transport for London Location: London Services: Groundwater Modelling Issues: Identifying the potential effects of pumping excess heat to the Chalk aquifer Summary: ESI was commissioned to test the feasibility of one of the possible solutions identified to prevent temperatures on the ...

  • Karst groundwater: a challenge for new resources

    Karst aquifers have complex and original characteristics which make them very different from other aquifers: high heterogeneity created and organised by groundwater flow, large voids, high flow velocities up to several hundreds of m/h, high flow rate springs up to some tens of m3/s. Different conceptual models, known from the literature, attempt to take into account all these particularities. The ...

  • Norfolk CC tackle groundwater contamination with low-flow

    Quick and easy access in deep wells Geotech low flow groundwater analysis equipment has enabled quick and easy access to samples at 2m intervals down a 28m screen in deep boreholes. Elizabeth Guilford of Norfolk County Council hired the low flow kit from Geotech and used it on a Norfolk CC landfill where leachate contamination of groundwater was suspected. Samples taken at 2m intervals ...

  • Groundwater contamination of 1,1,1-TCA, PCE - Manufacturing facility

    LOCATION:  Glen Cove, New YorkPROJECT DATE:  September 2000 to presentCLIENT:  Confidential BACKGROUND: Groundwater in a sand and gravel aquifer beneath this active manufacturing facility was contaminated with 1,1,1-TCA (concentrations up to 480 mg/L), PCE, and their degradation products. The site owner, faced with a long term (in excess of 100 years) and expensive pump and treat ...

  • 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 ...

  • Sources of Groundwater in Crystalline Hard Rocks of Kandy Area, Sri Lanka

    Abstract: Hydrogeological investigations were carried out to obtain sufficient information on groundwater availability in the fractured metamorphic rocks in Kandy district of Sri Lanka. 47 boreholes were drilled with the average depth of 90 metres and 24 high yielding wells were selected and long term pumping tests were carried out for each well using standard methods. The calculated total of ...


  • Impact of Non-Aqueous Phase Liquids (NAPLs) on Groundwater Remediation

    Nonaqueous Phase Liquids (NAPLs) are immiscible (undissolved) hydrocarbons in the subsurface that exhibit different behavior and properties than dissolved contaminant plumes. NAPLs have a tremendous impact on the remediation of contaminated aquifers, as it is very difficult or impossible to remove all of the NAPL from a hazardous waste site once released to the subsurface. Although many NAPL ...


  • Direct-Push Injection and Circulation Biobarrier to Remediate a TCE Groundwater Plume

    ABSTRACT: The goal of this study was to determine if direct-push drilling methods combined with a circulation system could be used to establish a passive biobarrier in a very transmissive aquifer to treat tricholoroethene (TCE). The Site is located in central Indiana, where historic use of TCE has impacted an unconfined aquifer. A plume consisting primarily of TCE has migrated from west to east ...

  • ISCR-Enhanced Bioremediation Accelerates Groundwater Cleanup at Active Manufacturing Facility

    In the winter of 2008, full-scale in situ chemical reduction (ISCR) was implemented as a removal action at the Siltronic Corporation site in Portland, OR, to treat a source area contaminated by releases of TCE. The source area was considered to be the portion of the site with concentrations of TCE in groundwater greater than 11,000 µg/L, suggesting the ...
