Abstract

The U.S. Geological Survey sampled the bottom sediment and water column of 11 streams tributary to western Green Bay for polychlorinated biphenyls, lead, and cadmium. Four of these streams also were sampled for dieldrin, a pesticide previously used in agricultural areas of the watershed. An additional 11 streams tributary to eastern Green Bay were sampled for dieldrin in the bottom sediment and storm runoff. Samples were collected from July 1987 through April 1988. The results of the sampling did not show the presence of detectable concentrations of dieldrin in the sampled tributaries. A low concentration of polychlorinated biphenyls (10 mg/kg) was found in the bottom sediment of Duck Creek, a western-shore tributary near the city of Green Bay. Lead (10 mg/kg) also was found in the bottom sediment of the Suamico River near the mouth. Lead (4 micrograms/L) was detected in the spring-runoff sample from the Fishdam River, a tributary from upper Michigan. (USGS)
