Public Health Assessment for Delavan Muni Well No. 4, Delavan, Walworth County,Wisconsin, Region 5. CERCLIS No. WID980820062

摘要

Groundwater in the Delavan area is contaminated with VOCs (volatile organiccompounds). This VOC contamination was measured in Delevan municipal water, from 1983 through 1993, but is not an apparent public health hazard because VOCs were not at levels that pose a health concern. Delavan Well No. 4 is an indeterminate public health hazard for past human exposures to contaminated drinking water. The full extent of contaminated groundwater in and around Delavan has not been determined and needs to be characterized. Ambient air exposure to VOCs from a storm sewer carrying treated water away from Sta-Rite Industries, a nearby manufacturer, is an indeterminate public health hazard. Sediments in Swan Creek, where treated water from Sta-Rite leaves the storm sewer, contained VOCs at levels that are not a health concern.
