  • Photodegradation of 4-chloronitrobenzene in the presence of aqueous titania suspensions in different gas atmospheres

    The photocatalytic degradation of 4-chloronitrobenzene (4-CNB) was carried out using Degussa P25 TiO2 as photocatalyst in three different gas atmospheres: nitrogen, oxygen, and ozone. The total organic carbon (TOC) and inorganic anions including chloride, nitrite, and nitrate anions were measured to monitor the mineralization processes, while the degradation of 4-CNB and the formation of ...

  • Enhanced In Situ Bioremediation of Chlorinated Solvents (PDF)

    Anaerobic enhancement of a shallow confined silty sand aquifer has resulted in a substantial biodegradation of a dissolved Tetrachloroethene (PCE) plume at a former metal finishing facility in Secaucus, New Jersey. The injection of a time-release hydrogen compound (HRC™) rapidly converted ambient aquifer aerobic conditions to anaerobic, and maintained such conditions throughout the 6-month ...

  • A Pilot Study Using HRCTM to Enhance Bioremediation of CAHs.

    ABSTRACT: The effect of Hydrogen Release Compound (HRCTM) in enhancing the anaerobic bioremediation of chlorinated aliphatic hydrocarbons (CAHs) was observed in a single well pilot study. HRC is a proprietary, environmentally safe, food quality, polylactate ester formulated for the slow release of lactic acid upon hydration. Microbes metabolize the lactic acid releases by HRC and produce ...

  • Enhanced Bioremediation of Tetrachloroethene in Central Indiana Glacial Till

    ABSTRACT: The goal of this project is remediation of soil and groundwater impacted by tetrachloroethene (PCE) that infiltrated the vadose and uppermost saturated zone below an active dry cleaning facility in central Indiana. PCE was released and transported to depths less than five meters via the primary porosity of thin sand and silt stringers and via secondary porosity of fractures in lodgment ...

  • TCE at Department of Defense Landfill Site

    PROJECT BACKGROUND Subsurface investigations at this 40-acre Northern California Department of Defense (DOD) landfill site revealed elevated levels of TCE in site soils and groundwater. This discovery was made through routine site monitoring, as regulated by the state of California solid waste landfill regulations. Regulators required site cleanup to reduce chlorinated hydrocarbon concentrations ...

  • PureAire Universal Gas Detector Offers Protection Against Toxic Levels of Ammonia

    In March of 2016, an ammonia gas leak at a seafood processing plant in Boston left one worker dead. The fumes at the plant were so powerful that firefighters could not promptly enter the scene to mitigate the gas leak and try to save the staff member until much later. Reports show that 5,300 pounds of ammonia gas leaked out of the plant. If you work with ammonia at your facility, learn ...

  • A Case Study in Implementation of the National Emission Standard for Hazardous Air Pollutants for the Portland Cement Industry at a Major Source

    The regulations at 40 CFR 63, Subpart LLL are commonly known as PC MACT because the rule establishes the maximum available control technology for hazardous air pollutants (HAPs) from portland cement plants in the United States. There are 188 HAPs specified in Section 112 of the Clean Air Act Amendments of 1990. Two classifications of HAP emitters are specified in 40 CFR 63. Major sources of HAPs ...

  • Results of the Application of Enhanced Reductive Dechlorination of Chlorinated Organics at Eight Sites (PDF)

    Enhanced reductive dechlorination is becoming more widely evaluated as a technology for the remediation of chlorinated organic compounds. The performance of this technology as reported in the literature, is often quite variable, making it difficult to evaluate the applicability of the technology. CH2M HILL has been involved in the application of this technology at several sites over the past few ...
