  • Rapid Reduction of VOCs Results in Site Closure

    Summary Subsurface investigations at a dry cleaning facility revealed elevated levels of PCE and other regulated daughter products. A remediation technology was needed that could cost-effectively reduce the contaminants to the Washington Department of Ecology’s (WDOE) cleanup levels. HRC was chosen for groundwater remediation due to its ability to provide a low cost solution for site ...

  • Indoor Air as a Source of VOC Contamination in Shallow Soils Below Buildings

    US EPA and many state regulatory agency guidance documents recommend below foundation vapor sampling as a key element of site investigations to determine if vapor migration from underlying soil into buildings is a completed exposure pathway (USEPA, 2002; WIDHFS, 2003; San Diego County, 2004; PADEP, 2004). If volatile organic compounds (VOCs) are detected below the building foundation, then VOC ...

  • Common Treatment Train for Halogenated VOCs

    In general, no single technology can remediate an entire site. Several treatment technologies are usually combined at a single site to form what is known as a treatment train. A system diagram of a common treatment train for halogenated VOCs is illustrated below. A ground water pumping system is used to pull contaminated water from the subsurface. The VOC contaminated water is pumped to a liquid ...

  • 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 ...

  • Control VOC`s in Refinery Wastewater

    Oil and water do not mix, like many of life’s one-liners this statement is basically true but not the whole story. Many hydrocarbon liquids, particularly aromatics, have significant solubilities in water: Benzene 1800 PPMVToluene 470Ethyl Benzene 150Xylenes 150 Petroleum refineries do not like salts in their feedstock since these corrode and foul process equipment. The first refining step is ...

  • Hydrogeologic Investigation of VOC Contamination in Bedrock Using Mass Flux Analysis – A Case History

    Courtesy of US EPA and NGWA proceedings of the 2004 U.S. EPA/NGWA Fractured Rock Conference: State of the Science and Measuring Success in Remediation, September 13-15, 2004, Portland, Maine AbstractA fractured bedrock system was investigated using a combination of hydrogeologic methods to minimize the number and depth of bedrock wells installed during the investigation. These ...

  • VOC Remediation Using HRC at Navy Base

    Site Summary Site investigations at a Naval Base in Long Beach, California revealed high contaminant levels of volatile organic compounds (VOCs) from a dry cleaning operation. In well MW-14-S4, the contamination levels of DCE, TCE and PCE reached 4,100 μg/L, 4,000μg/L, and 6,500 μg/L, respectively. The land use in this vicinity was primarily industrial and operations ceased by ...

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

    It may be necessary to know other subsurface information to provide remediation of VOCs in the ground water. Treatability studies to characterize the biodegradability may be needed for any biodegradation technology. Treatability studies are usually necessary to ensure that the contaminated ground water can be treated effectively at the design flow. A subsurface geologic characterization would be ...
