  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Emergency remediation response case study

    Services Performed Emergency remediation response, oil and hazardous waste consulting and a mold/indoor air quality (IAQ) testing Summary Following the flooding of the Spicket River during the Spring 2006, EFI Global was engaged to evaluate a nursing home in Lawrence, MA. After the initial environmental evaluation, our team observed that the basement and ...

  • Perchlorate Remediation Project Case Study

    ARCADIS was contracted in 2000 to lead the development, evaluation and selection of a final groundwater remedy for this 94-acre site in California. As part of this work, ARCADIS is also participating in the evaluation of innovative technologies with the potential to treat soil impacts in the multiple source areas across the site. Specifically, the project is focused on the remediation of seven ...

  • Case study - Mobile remediation system

    OVERVIEW A large consulting and contracting firm owns and operates several ex-situ Thermal Desorption Units (TDUs). Each single-load Thermal Desorption Unit has the capacity of desorbing 15 tons of soil per hour at a temperature of 400°F - 900°F. These Thermal Desorber Units have been designed to operate on both chlorinated and non-chlorinated RCRA, CERCLA, and private industry ...

  • 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), ...

  • Soft subgrade remedies under heavy axle loads - 2.5-year TTCI test results

    Rapid track geometry degradation can occur under heavy axle loads. Several proposed remedies for this deterioration have been evaluated on the Heavy Tonnage Loop at the Transportation Technology Center, Inc., Pueblo, Colo. A 700-foot-long, soft-subgrade test track, installed in the HTL, provides a nominal track modulus of 2,000-to-2,500 lb/in./in. This section is referred to as the low track ...

  • Spolchemie site remediation and NanoRem field site application

    Site Remediation The Spolchemie site was chosen as one of the NanoRem case study sites, to test two types of nanoparticles (NPs) (zerovalent iron - nZVI and iron oxide NPs) for in situ remediation of BTEX (Benzene, Toluene, Ethylbenzene, and Xylenes) contamination. Nanoremediation was seen as an opportunity to enhance the in situ biodegradation of the BTEX contaminants and to reduce the ...
