Title: Volatile Chlorinated Hydrocarbons in Ground and Lake Waters
Abstract: Tetrachloroethylene concentrations in ground waters in the Zurich area have been found to range from less than 0.1 to 82 μg/1, with the highest concentrations in an industrial section of Zurich. A subsequent survey of ground waters in this industrial area found a series of volatile chlorinated hydrocarbons, including 1,1,1-trichloroethane, carbon tetrachloride, 1,2-dichloroethylene, trichloroethylene, and tetrachloroethylene. In all samples, tetrachloroethylene was the dominant chlorinated compound, with concentrations between 0.4 and 237 μg/1. The most likely source of this ground water contamination is chronic spillage of small quantities of the solvent. Vertical profiles of several volatile chlorinated hydrocarbons have been measured in Lake Zurich. Tetrachloroethylene (50-120 ng/1), 1.4- dichlorobenzene (10-35 ng/1), and carbon tetrachloride (20-35 ng/1) were the most abundant compounds. Profiles of tetrachloroethylene and 1.4-dichlorobenzene showed peaks of maximum concentration at a depth of about 10 m. These maxima are believed to represent a tongue of treated sewage effluent. Thus these two persistent chemicals may be useful as microtracers of wastewater movement in lakes. Quantitative details of the volatile organic compounds in waters such as those studied for this report are highly desirable since these waters are used as sources for public drinking water supplies.
