  • Field Demonstration of a Permeable Bioreactive Barrier for Leachate Control.

    ABSTRACT: A biostimulation technique was selected for a pilot study to treat groundwater at a former New Jersey municipal landfill. The process will address a mixture of chlorinated compounds (e.g. vinyl chloride and chlorobenzene), hydrocarbons (e.g. benzene and methyl ethyl ketone) and heavy metals. The reactive barrier will be constructed using a series of injection points to implace a slurry ...
