Lead pollution in soils in Milwaukee County, Wisconsin

Abstract

An analysis of 372 samples collected throughout Milwaukee County, Wisconsin demonstrates that a significant lead pollution problem exists. A summary of the data broken down by neighborhood reveals that lead contamination is greatest in the Central City neighborhood of the Milwaukee County and that the magnitude and extent of the pollution decreases away from the Central City toward the suburban fringe. It is important to note, however, that soil samples containing hazardous levels of lead were found in all neighborhoods of the county. These data suggest that although lead is concentrated in the central portions of cities, lead education, abatement, and monitoring may be necessary in all portions of cities. This suggested approach is in conflict with current strategies of lead monitoring that target one geographic area or that select a population for monitoring based upon socioeconomic status.
