  • Proof of concept for the use of macroinvertebrates as indicators of PCB contamination in Lake Hartwell

    The U.S. Environmental Protection Agency (EPA) develops methods and tools for evaluating risk management strategies for sediments contaminated with polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs), and other legacy pollutants. Monitored natural recovery (MNR) is a risk management alternative that relies on existing physical, chemical, and biological processes to ...

  • Bioremediation of PCB & Pesticide Contaminated Soils Utilizing Gene Expression Factors

     Abstract Historically soils contaminated by persistent organic compounds such as pesticides and PCBs were not considered good candidates for bioremediation due to the simple fact that the chemical industry designed these compounds to withstand the destructive effects of natural attenuation through weathering and microbial activity. Although the chemical industry has long appreciated the ...

  • Health Effects of PCBs

    Many studies have been performed in order to know the effects of PCBs on human health. Some of these studies suggest that PCBs are a possible factor in the appearance of cancer in humans who have been in contact with the substance, while they have already been demonstrated to cause a variety of adverse health effects and have been shown to cause cancer in animals. ...

  • Sonic Environmental Files Process Patents for Remediation of PCB Contaminated Soils

    Untitled Document Sonic Environmental Solutions Inc. (SNV.TSX Venture) today announced that the process definition phase of testing of the Company’s main application to remediate PCB ...


  • Converting the dreaded PCBs into useful commodities

    For decades polychlorinated biphenyls (PCBs) have been high on the list of toxins the public fears. A new vitrification technology is claimed to be able to completely destroy PCBs and other toxins in contaminated sediment by meltingit into a glass aggregate product that can be used in the construction industry. This process, developed by Minergy Corp., costs about as much as landfilling, without ...

  • The 1998 PCB Disposal Amendments: Guide to the 1998 PCB "Mega Rule"

    INTRODUCTION On June 29, 1998, the U.S. Environmental Protection Agency (EPA) promulgated a sweeping series of changes in the PCB regulations under the Toxic Substances Control Act (TSCA). Commonly known as the Mega-Rule or PCB Disposal Amendments (due to its focus largely on waste management issues), this long-awaited rule encompasses more than 80 changes in the regulations and spans more ...

  • What is a wastewater treatment system and how does it work?

    For industrial companies producing wastewater as part of it’s process, some type of wastewater treatment system is usually necessary to ensure safety precautions and discharge regulations are met. The most appropriate wastewater treatment system will help the facility avoid harming the environment, human health, and a facility’s process or products (especially if the wastewater ...

  • Surface Decontamination of PCBs (PCB-laden oil) by DeconGel 1101 and 1102

    Abstract Field testing aboard the USS Missouri maritime museum vessel showed that excellent surface decontamination was achieved by applying DeconGel™ 1102 onto contaminated surfaces, resulting in encapsulation of PCB contaminant by DeconGel's active components. For all contaminated surfaces tested, EPA PCB limit standards (Regulations 761.79, 761.123) of < 10 ug/100 cm2 were ...

  • B.C. Company Clean PCB Onsite

    A parcel of a land owned by Juker Holdings Ltd on British Columbia's Annacis Island is similar to many other brownfields sites across North America. The former industrial site on 4.3 hectacres contained 3,000 tons of soil contaminated with polychlorinated byphenils from years of copper tubing and related industrial operation. What's different about the Juker site, however, is that it is ...


  • Sonic making inroads on PCB remediation?

    The Sydney Tar Ponds of Nova Scotia are the result of a century of coal mining and steelmaking, which left behind 900,000 tonnes of chemical waste. About 5 per cent or 45,000 tonnes of this waste is contaminated with high levels of PCBs. Two years ago a federal-provincial plan was announced to clean up the Tar Ponds over 10 years at a cost of $400 million, and this led to the creation of the ...

  • Continued Use of PCB-Contaminated Concrete Through Implementation of the 40 CFR 761.30(p) Use Authorization

    The 40 CFR 761.30(p) use authorization for PCB-contaminated porous surfaces was applied to concrete floors at an electric utility’s transformer shop and PCB storage building. This authorization allows PCB-contaminated concrete to be managed in place while it remains in service, provided that it is surface washed, encapsulated, and marked to indicate the presence of PCBs that will ultimately need ...

  • Assessing atmospheric concentration of polychlorinated biphenyls (PCBs) by evergreen Rhododendron maximum next to a contaminated stream

    Conifers are often used as an “air passive sampler”, but few studies have focused on the implication of broadleaf evergreens to monitor atmospheric semivolatile organic compounds such as polychlorinated biphenyls (PCBs). In this study, we used Rhododendron maximum (rhododendron) growing next to a contaminated stream to assess atmospheric PCB concentrations. The study area was located in a ...

  • PCB profiles in ringed seals (Pusa hispida) reveal historical contamination by a military radar station in Labrador, Canada

    Significant amounts of soil contaminated with polychlorinated biphenyls (PCBs) were discovered at a military radar station in Saglek Bay, Labrador (Canada) in 1996, and subsequent work found elevated PCB concentrations in local marine sediments, the benthic‐associated food web and in some ringed seals (Pusa hispida). The benthic‐associated food web clearly reflected local PCB contamination, ...
