  • A Citizen`s Guide to Chemical Dehalogenation

    What is chemical dehalogenation? Chemical dehalogenation is a chemical process to remove halogens (usually chlorine) from a chemical contaminant, rendering it less hazardous. Halogens are a class of chemical elements that include chlorine, bromine, iodine, and fluorine. Polychlorinated biphenyls are halogenated compounds that once were used in high voltage electrical transformers because they ...

  • Dressing down groundwater contamination

    Unlike the late Paul Newman, who bottled his special-recipe salad dressing and sold it in supermarkets, Dr. Robert Borden simply mixes up his own 'dressing' and pumps it into the ground. That’s because the environmental engineering professor and his graduate students are more interested in feeding microbes to clean up contaminated groundwater than in making just another Ranch dressing. “It’s ...

  • Enhanced anaerobic bioremediation of chlorinated solvents utilizing vegetable oil emulsions

    The use of vegetable oil as an electron donor to enhance the reductive dechlorination of chlorinated solvents as an in situ remediation technology is gaining significant traction. Vegetable oil is a cost-effective slow-release electron donor with greater hydrogen-release efficiency than other electron-donor products. However, neat vegetable oil can inhibit distribution in aquifers due to the oil ...
