  • Vapor intrusion mitigated through solar-powered exhaust systems

    EPA Region 6 undertook a Superfund removal action earlier this year at the Delfasco Forge site in Grand Prairie, TX, to address trichloroethene (TCE) vapor migrating from a groundwater plume. Region 6 and the State had determined after extensive site investigations that technologies such as soil vapor extraction or natural attenuation would require several years to remove or reduce the plume ...

  • 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 ...

  • LNAPL remediation using electrical resistance heating

    Abstract An Electrical Resistance Heating (ERH) pilot test was conducted in the fall of 1998 to determine the effectiveness of using ERH in combination with soil vapor extraction (SVE) for the remediation of benzene and light nonaqueous-phase liquids (LNAPL) at an island location on a river in the Midwest. Hydrocarbon-stained soils were discovered on an island in Ohio in May 1993 during the ...

  • Refinery remediation: fuel recovery and recycling

    Introduction The site is a former refinery that occupied approximately 64 acres of land in West Texas. Refinery operations produced all grades of gasoline, tractor fuels, diesel, distillate products, and fuel oils and operated between 1939 and 1954. As a result of past waste management practices, releases to soils and ultimately ground water occurred, resulting in the formation of a ...

  • Common Treatment Technologies for Fuels in Ground Water, Surface Water, and Leachate

    It may be necessary to know other subsurface information to remediate fuels in ground water. Treatability testing to characterize contaminant biodegradability and nutrient content may be needed for any biodegradation technology. A subsurface geologic characterization would be particularly important to characterize the migration of NAPLs. Recovery tests are usually necessary to design a ...

  • Chlorinated solvents: methylene chloride and TCE

    Introduction This paper presents the results of a scaled and phased approach to source remediation of high concentrations of recalcitrant chlorinated solvent compounds via soil vapor extraction (SVE) and vapor treatment at a Site in Southern California. Phase I began with refrigerated condensation (C3) in order to achieve high mass removal rates to reduce lifecycle costs and time ...

  • 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 ...

  • Case study - Pemaco superfund site remediation

    OVERVIEW Pemaco was formerly a chemical facility located in a light industrial and residential area of Maywood, CA, adjacent to the Los Angeles River. No one knows how long hazardous substances had been leaking into the ground but the operations date back to the 1940's.  Up until closure of the facility in 1991, chlorinated solvents, aromatic solvents, and flammable liquids had ...

  • Case study – benzene contamination retail gas station, Colorado

    Introduction The scope of work for this site included an expansion of an existing soil venting system to remediate impacted soil and injection of a carbon-based petroleum degrading product to remediate long-term groundwater impacts. By using a combination of remediation technologies, including LT Environmental’s (LTE) TerraCert™ program, the overall goal of a cost effective cleanup ...

  • 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 ...
