  • Effect of OSE(II)-Enhanced Soil Washing(OESW) for TPH -Contaminated Soil Remediation

    The objectives of this study were to perform potentially suitable active agent that solubilize total petroleum hydrocarbon (TPH) present as contaminants and to evaluate the optimal range of process parameters that can increase the removal efficiency in OSE(II)-enhanced soil washing (OESW) pilot tests. Used experimental method for solubilisation of TPH by using OSE(II) was batch experiments. The ...

  • In-Situ Treatment - Funnel & Gate System - Case Study

    Problem An asphalt testing facility, in operation for many years, closed in the early 1990s. A subsequent environmental assessment revealed that an underground storage tank, used to hold common cleaning/degreasing solvent for use during testing, had developed a leak and had to be abandoned. The storage tank and soil in the immediate vicinity was removed as the first step to remediate ...

  • Test area North Chloroethene source area remediation project

    Background A contaminant source area resulted from the injection of chlorinated solvent-containing liquid waste and sanitary sewage to the Snake River Plain Aquifer from the mid-195s to 1972. The source is primarily an organic sludge containing up to 3% TCE. The sludge is present in the fractured basalt surrounding the former injection wells. A plume of TCE in ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Remediation consultancy, South Wales

    Project Remediation Strategies were retained to assist a large chemical facility with the long term management of a groundwater contamination issue. Contaminants had historically entered groundwater following a spill event and despite previous remediation works by others, a residual contaminant plume remained present and was continuing to migrate off-site. Following on from previous ...

  • Filter bed remediation - Case Study

    Biological filter beds usually consist of a mineral media over which effluent to be treated percolates. The media becomes host to a biomass which is grazed by a series of more complex organisms. If the growth of the biomass is greater than the rate at which the grazing occurs then the biomass film will accumulate in the bed. This will block the interstices of the media and restrict effluent ...

  • 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), ...

  • An investigation and remediation of TNT contaminated soils.

    An investigation and remediation of TNT contaminated soils and wastes was conducted at the Apache Powder Superfund Site in Cochise County, Arizona during 1999 and 2000. TNT contamination was most likely the result of salvage operations of World War I munitions. Characterized by a steep hillside and arroyo cutting through the wastes, the site offered challenges of stability, access, health and ...

  • Fractured Bedrock Remediation - Case Study

    ABSTRACT BOS 200® successfully remediates petroleum groundwater impacts in fractured bedrock at a former truck stop. Based on the post-injection groundwater results from the pilot test and full-scale injection, a No Further Action letter was issued in February 2015. CHALLENGES Over a period of 20 years, site investigation activities revealed a 320 foot ...

  • Mold Remediation Guidance For Indoor Environment

    Remediation contractors are generally very conscientious, trying hard to bring each project to a condition where it will pass “clearance  testing” (the  Post-Remediation  Verification  [PRV] inspection) on the first try. Sometimes the cleaning attempts are unsuccessful. This will certainly cost the contractor additional cleaning ...

  • TCE/Fractured Bedrock Remediation in VA

    Site Summary At a manufacturing facility HRC was injected into a crystalline bedrock aquifer contaminated with TCE and its daughter products. Groundwater flow at this site is controlled by fractures in the crystalline rock with little or no permeability present beyond these fractures. The industrial facility had been in operation for over 30 years. Contamination levels reached 220 ppb of TCE so ...
