  • Air sparge system - Case Study

    ERC was contracted to install an air sparge system in Central Ohio. Air sparging is an in situ remedial technology that reduces concentrations of volatile constituents in petroleum hydrocarbons adsorbed to soils and dissolved in groundwater. This involves the injection of contaminant-free air into the subsurface saturated zone, enabling a phase transfer of hydrocarbons from a dissolved state to a ...

  • Insitu Cleanup in Less than 5 Months

    The owner of the property obtained pricing to clean up the property from several environmental companies and the cost was approximately $230,000.00 for a typical air sparge, vapor recovery system. The time frame for cleanup was approximately 3 years with no guarantee that the site would ever clean up or the cleanup costs would not increase. Bioworld/Southeast priced the cleanup for the same ...

  • Common Treatment Train for Nonhalogenated VOCs

    A treatment train is the combination of different treatment technologies. A system diagram of a common treatment train for nonhalogenated VOCs is illustrated below. A soil vapor extraction system is used to pull VOC vapor from the contaminated soil. An air sparging system delivers air below the water table to enhance bioremediation. After passing through a liquid/vapor separator, the VOC ...

  • Active Taxiway Remediation

    Introduction: How do you remediate beneath an active airport taxiway without interfering with commercial airliners and United States Air Force cargo planes taxiing through your work area at 60 miles per hour? This was the problem facing the Department of Defense (DoD) at a site impacted with jet fuel. To solve the problem, our long-time client, FPM Remediations, ...

  • Soil and Ground Water Remediation Case Study

    On this State Funded Clean-Up project, Global was the project engineer and was responsible for the design of an air sparging/soil vapor extraction remediation system. The system included five soil vapor extraction wells and twelve sparging wells that operated on a rotating schedule. One of the soil vapor extraction wells and nine of the sparging wells were installed as horizontal wells beneath ...

  • Introduction to Ozone Injection Technology

    Untitled Document Ozone is a highly reactive chemical that has proven to be effective in destroying a wide variety of organic chemicals, including MtBE and chlorinated VOCs. ...

  • Site Closure Sought after using ORC® Biobarrier to Enhance Aerobic Biodegradation of MTBE and TPHg

    CASE SUMMARY Former Service Station - Bishop, CA Extensive methyl tertiary-butyl ether (MTBE) and total petroleum hydrocarbons as gasoline (TPHg) contamination was discovered within the subsurface as a result of leaking underground storage tanks (USTs) at a former service station. Following the removal of the leaking USTs, a total of 1,192 cubic yards of gasolineimpacted ...

  • Raynesway resource park - Case Study

    The Raynesway Resource Park is a 35 hectare site bounded on three sides by the River Derwent. The southern half of a former chemicals plant, soils and groundwaters were impacted by chlorinated solvents, acid tars, hydrocarbons and ammoniacal sludges. Celtic designed a sophisticated groundwater treatment system, integrating air sparging, multi-phase extraction and chemical oxidation to address ...

  • Common Treatment Technologies for Nonhalogenated VOCs

    Soil vapor extraction (SVE), thermal desorption, and incineration are the presumptive remedies for Superfund sites with nonhalogenated VOC-contaminated soil. Because a presumptive remedy is a technology that EPA believes, based upon its past experience, generally will be the most appropriate remedy for a specified type of site, the presumptive remedy approach will accelerate site-specific ...

  • How to Remediate under an Intersection with Horizontal Wells

    Roadway intersections within urban settings are arguably some of the most challenging areas for subsurface remediation. Many consultants tasked with remediation of challenging sites such as these become frustrated by the inability of a vertical remediation system to influence the area of concern and/or they are anxious that they will not efficiently bring their clients’ sites to ...

  • Reconsidering horizontal to vertical well ratios for site clean-up

    Directional drilling has been used for a variety of purposes; utilities, dewatering, and remedial activities. Cutting costs for remedial activities it is always of consideration. What the costs are to clean-up a site via traditional vertical extraction wells versus using a horizontal well system needs to be reconsidered based upon todays remedial challenges. Traditionally, it has been stated that ...

  • ORC vs. AS/SVE Cost Comparison at UST Site, Covington, IN

    Site Summary The site, located in Covington, Indiana, was chosen for a pilot test, to demonstrate the effectiveness of ORC in treating the existing benzene and MTBE concentrations. Contamination in the groundwater had resulted from leaking gasoline UST’s. In addition to the pilot test, a cost-comparison was also prepared to illustrate the potential for cost savings associated with the use of a ...

  • Peroxygen Mediated Bioremediation of MTBE.

    ABSTRACT: Evidence is mounting, from laboratory and field studies, that oxygen plays a role in the bioremediation of methyl tertiary butyl ether (MTBE). Our experience with a number of commercial applications of peroxygen, in the form of Oxygen Release Compound (ORCâ), correlates the provision of enhanced aerobic conditions with enhanced MTBE biodegradation. Subsequent laboratory and field ...
