PESTAB The use of polyurethane foam plugs has been a good alternative to use of carbon in extracting trace polychlorinated biphenyls and organochlorine pesticides from water. A standard carbon adsorption metering apparatus was used, but carbon was replaced by polyurethane foam. Water at the treatment plant in Morris, Manitoba, was sampled before and after the carbon-alum-chlorine treatment. Organic material was extracted from the foam plugs with hexane. The hexane extract was concentrated to 5 ml and analyzed by electron capture GC. Organic contaminants in raw river water were not significantly reduced by the treatment process, but levels were below the 100 ppb limit set for drinking water.
