  • Duke Energy Fined $102 Million for Polluting Rivers with Coal Ash

    Duke Energy, the nation's largest electrical utility, pleaded guilty in federal court Thursday to nine criminal violations of the Clean Water Act for polluting four major rivers for several years with toxic coal ash from five power plants in North Carolina.

  • Minnesota Communities Oppose City's Planned Sewage Treatment Facility

    Residents of nearby Lake St. Croix Beach and St. Mary's Point fear the project would cause more environmental problems than it solves. Among other concerns, they fear that Valley Creek -- a protected trout stream -- could be harmed and groundwater near drinking water wells could be contaminated.

  • Incinerating Hazardous Waste

    Through incineration, hazardous wastes can be safely and efficiently discarded.

  • Five Companies Win European Business Awards

    Karmenu Vella, the European Union's Environment, Maritime Affairs and Fisheries commissioner, has announced the winners of the European Business Awards for the Environment 2014-15.

    "Most industries that currently flare their waste gases will soon be able to use these waste gases productively while also significantly reducing their emissions of waste gases into the atmosphere. This is great news for our world's air quality and great news for the financial bottom lines of the industries that currently emit these greenhouse gases into the atmosphere," said Alain Castro, CEO of Ener-Core.

  • Mercury Control with Regenerative Activated Coke Technology

    The multi-pollutant control ReACT™ technology is a completely dry scrubbing system based on adsorption of SO2, SO3, and Hg and reduction of NOx to N2 on activated coke in a moving bed, with regeneration of the coke for return to the adsorber, and production of saleable byproduct, such as sulfuric acid, from desorbed sulfur rich gases.

  • Why Activated Carbon Makes Sense for PCB Remediation

    For about 50 years, polychlorinated biphenyls (PCBs) were commonly used in industrial materials including, caulking, cutting oils, inks, paints and as dielectric fluids in electrical equipment such as transformers and capacitors. Concerns over health effects led to a North American ban of manufacturing PCBs in 1977. By the mid-1980s, an initiative was started to clean up contaminated areas and to phase out PCB-containing equipment and products that were still in use. This cleanup effort continues today.

  • Adventus Field Profile

    Groundwater at an industrial site in Texas is impacted with Chlorinated Volatile Organic Carbon’s (CVOCs), primarily PCE and TCE, from historical waste disposal. The topography at the site slopes steeply towards a small channel where the groundwater discharges. Depth to groundwater ranges from approximately 20 ft bgs at the source area to 1 ft bgs close to the channel.
