  • Groundwater Remediation

    Groundwater remediation or clean-up is required when concentrations of contaminants exceed or are expected to exceed predetermined levels for the type of resource that is impacted (Grossman et.al., 2008). For example, lead levels in drinking water should not exceed the EPA action level of 0.015 mg/L. What caused the high levels of lead? How can the lead be removed from the aquifer? (Grossman ...

  • Groundwater Remediation Strategies Tool

    This guide provides strategies for focusing remediation efforts on 1) the change in contaminant mass flux in different subsurface transport compartments (e.g. the vadose zone, smear zone or a zone within an aquifer of interest) and 2) the change in remediation timeframe. In this approach, groundwater flow and contaminant concentration data are combined to estimate the rate of contaminant mass ...

  • Recent papers in groundwater remediation

    Computational cost is a critical issue for large-scale water resource optimization under uncertainty, since time-intensive Monte Carlo simulations are often required to evaluate over multiple parameter realizations. This paper presents an efficient approach for replacing most Monte Carlo simulations with efficient surrogate models within a noisy genetic algorithm (GA). The surrogates are trained ...

  • Soil and groundwater remediation

    At a site in northern Indiana on behalf of a multinational client, Troy Risk operated a groundwater remediation system to cleanup the source of chlorinated solvent impact to a groundwater aquifer system. Prior to 1988, the site was occupied by a manufacturing facility. In March 1995, chlorinated volatile compounds (CVOCs) were detected pursuant to due diligence for real estate refinancing. From ...

  • BTEX remediation in groundwater

    BTEX contamination in groundwater from a leaking underground storage tank was cost-effectively treated with two applications of Petrox. This project demonstrates the rapid degradation of petroleum components when high populations of Petrox aerobic microbes are injected. The pre-treatment concentrations of Toluene and Xylene were 1,198ppb and 2,408 ppb, respectively. Ten units of Petrox aerobic ...

  • Moderator shares how upcoming conference will foster development of new technologies in fractured rock

    Ken Goldstein, CGWP, will moderate a session titled “High-Resolution Characterization in Fractured Rock” at the upcoming 2017 NGWA Conference on Fractured Rock and Groundwater, October 2-3 in Burlington, Vermont. Goldstein is senior vice president, water and environmental systems at Louis Berger. He recently ...

  • 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 ...


  • Remediation Of MTBE Contaminated Soil And Groundwater

    Methyl tertiary-butyl ether (MTBE) is a fuel additive made, in part, from natural gas. Since 1979, it has been used in the United States as an octane enhancing replacement for lead, primarily in midand high-grade gasoline at concentrations as high as 8 percent (by volume). Since the mid-1980s, it has been widely used throughout the country for this purpose. It is also used as a fuel oxygenate at ...

  • Groundwater remediation with Hydrogen Release Compound

    A substantial manufacturing site in Harlow, Essex, was contaminanated with chlorinated solvents used in degreasingoperations. The main compounds of concern were trichlorethene (TCE), trichlorethane (TCA) carbon tetrachloride (CT) and daughter products. The groundwater was at a depth to water of approximately 1.75m with a river around 600m to the north. Glacial deposits included variable clay ...

  • Remediation of Metals-Contaminated Soils and Groundwater

    A range of technologies is available for remediation of metals-contaminated soil and groundwater at Superfund sites. General approaches to remediation of metal contamination include isolation, immobilization, toxicity reduction, physical separation and extraction. These general approaches can be used for many types of contaminants but the specific technology selected for treatment of a ...

  • Remediation technology of groundwater contaminated by perchloroethylene

    To dechlorinate perchloroethylene (PCE), batch experiments were conducted for five groups of reactors: zero-valent iron (Fe0), zero-valent zinc (Zn0), an anaerobic microbial community (MB), a combination of iron powder and an anaerobic microbial community (FeMB), and combination of zinc powder and an ...

  • Groundwater Remediation System Cleans Up Oil Spill

    A customer in TX was recently in some hot water with the local municipal water department. Due to excessive rains near the coast of Texas, the water levels have been higher than usual. The company fills storage tanks with diesel at its facility. However one day the tanks were overfilled and instead of going into the ground, they diesel dispersed out via the high rain water and into the local ...

  • GCW as a means of efficiently remediating contaminated groundwater

    With the conventional 'Pump & Treat' method, groundwater is normally extracted from one or several wells, cleaned above ground and disposed off to the either groundwater or surface water. Even when extraction and injection wells are combined, predominantly higher perme-able areas are preferentially penetrated and more fine-grained structures are circumflowed. The bulk of contaminants are ...

  • Diesel and Gasoline Remediation in Groundwater and Soil at a DoD Site

    Site Summary Three above ground storage tanks (containing gasoline and diesel) and associated piping were removed from a DoD site in January 1990. Concentrations of TPHd and TPHg were found in soil samples collected around the former ASTs at concentrations of 140 mg/kg and 9,400 mg/kg, respectively.  Groundwater contamination was also detected with TPHd concentrations reaching 21,000 ug/L ...
