  • PCB Opportunities

    Polychlorinated biphenyls (PCBs) have not received much attention as of late. However, with the global clean-up market for PCBs estimated at $40 billion, getting into this market does deserve some consideration. LEGISLATION Canadian legislation currently requires that PCBs taken out of service be safely stored on-site. In certain Canadian jurisdictions, there was a move by the regulator ...

  • 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. ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Moderate size PCB contractor and aerospace contractor

    "If you're buying a cleaner from us, why not buy a closed-loop wastewater recycling system from us at the same time?" discussion: One cleaner vendor supplied a complete cleaner and separate closed-loop WASTEWATER recycling system to each of two different customers in California. After the systems were installed, neither customers could get the systems to function as a closed-loop ...

  • Petition regarding health problems caused by PCB in Slovakia

    Alena Bartonova at NILU has together with researchers in the EU project ENVIRISK sent a petition to the Government of Slovakia. This untraditional action has been taken to point out the need to remediate the environmental contamination in an area around a former production site for PCBs. Despite the fact that the production was stopped in 1984, large areas are still heavily polluted by PCB. The ...
