  • 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 ...

  • The Progression of Remediation

    Environmental remediation involves the cleanup of contaminated ground water and/or soils impacted by a variety of contaminates. The predominate contaminates over the years have been petroleum hydrocarbons from leaking underground storage tanks and surface spills, as well as solvents and other volatile organic compounds (VOCs) from industrial processes. Today, the most effective, practical, and ...

  • In situ Chemical Oxidation: An Innovative Groundwater Remediation Technology

    A promising new technology, in situ Chemical Oxidation (ISCO), has the potential to supplant the more widely used pump-and-treat groundwater remediation technology by destroying groundwater contamination in situ (in place). ISCO is the process of oxidizing contaminants in the groundwater and soil by injecting water containing high concentrations of an oxidant to the site of the contamination. ...

  • A Chemical Dynamics Model for CAH Remediation with Polylactate Esters.

    ABSTRACT: The polylactate esters of sorbitol, xylitol and glycerol are a class of new chemical compounds that slowly release lactic acid into groundwater. The lactic acid is biotransformed into pyruvic acid and subsequently into acetic acid releasing hydrogen in both steps. The hydrogen is used by naturally occurring dechlorinating bacteria to reduce PCE to ethene by way of TCE, DCE and VC. A ...

  • The power of precise remediation

    Design matters in in-situ remediation. Just ask Resource Geoscience, Inc. (RGI), a Remediation Products, Inc. BOS 200 approved installer and certified Trap and Treat Consultant. They recently demonstrated that when paired with proper injection design and precise application, BOS 200 can get the job done where others fail. The site:  Contaminated clay site in Colorado ...

  • Risk 101 & Remediation Design

    Risk Assessment is the basis for almost all of our designs. Perceived risk is the basis for the rest of the designs. A good remediation design must incorporate the concentration goals for that site and the designer must know how those goals were set. In order to know how those goals were set, we all must have a basic understanding of Risk Assessment. Not just the numbers, but the methodology that ...

  • Standard Chlorine of Delaware Remediation

    By designing a 70-foot deep barrier wall, Black & Veatch was able to cut off contaminant source areas from a creek near New Castle, Delaware. The groundwater treatment system that Black & Veatch designed prevents site contamination from reaching the underlying drinking water aquifer. The Standard Chlorine of Delaware Site is a 65 acre area including an abandoned chlorobenzene ...

  • Chloroflourocarbon (CFC) remediation case study

    Project Description The Site location was an industrial facility located in the greater South Los Angeles region that manufactured chemicals for local petrochemical and other industrial operations from 1919 through late 1990’s. Refrigerants were initially produced in 1964 including chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) such as trichlorofluoromethane (R-11), ...

  • Stevens Enhances Groundwater Remediation Effectiveness

    The Stevens HydraProbe is now being used to monitor the progress of a new groundwater pollution clean up method called phytoremediation. Phytoremediation is the method by which trees are used to pull contamination out of groundwater. Remediation of contaminated aquifers can take many years to complete. The ...

  • GCL serves as cap in brownfield remediation site

    PROJECT: Patterson Plank Road Brownfield Remediation LOCATION: Patterson, New Jersey PRODUCTS: BENTOMAT® SDN BACKGROUND: This New Jersey brownfield was formerly the site of a chemical recycling facility. CHALLENGE: The soil at the site was heavily contaminated, and off-site removal would have ...

  • Bioaugmentation is a cost-effective and sustainable remediation alternative

    Selecting a remediation alternative that is compatible with the natural soil and ground water conditions is not only a more sustainable approach, but leads to significant savings. Comparison between bioaugmentation and other remediation methods in the five recognized sustainability criteria demonstrates the advantages of bioaugmentation. While this paper is nota complete quantitative analysis, it ...

  • 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 ...

  • In-Situ Anaerobic Remediation of Perchlorate-Impacted Soils

    AbstractARCADIS is currently leading the development, evaluation, and selection of a final groundwater remedy for a 94-acre manufacturing facility in the western U.S. This facility has produced small explosives and vehicular safety products since 1957. As a result of historic operations, soil and groundwater at the site have been impacted by perchlorate. To date, remediation efforts have been ...

  • 99% of Interceptor contamination remediated - Case study

    What is an Interceptor Tank? An interceptor tank is a trap used to filter out hydrocarbon pollutants from rainwater runoff. It is typically used in road construction and on petrol station forecourts to prevent fuel contamination of the water table via runoff. Petrol interceptors work on the premise that some hydrocarbons such as petrol and diesel float on the ...

  • Consideration of the Effects of Remediation Technologies on Natural Attenuation.

    ABSTRACT: We have long understood and continue to improve our understanding of the geochemical conditions that favor biodegradation of petroleum hydrocarbons. Over the last several years our understanding of the conditions that are necessary for and/or promote reductive dechlorination of chlorinated hydrocarbons has improved substantially. Over this time in situ remediation technologies have ...

  • Accelerated Bioremediation as an Alternative to Conventional Remedial Technologies.

    ABSTRACT: Application of bioremediation as an alternative technology to expedite soil and ground-water remediation has been effective in reducing the concentration of hydrocarbons at an affordable cost. Bioremediation processes can be achieved by the addition of biological organisms into the soil and ground water which are contaminated and are microorganism deficient. The microorganism's ...
