A HISTORY OF SOIL CONTAMINATION OF AN URBAN AREA FROM HEAVY INDUSTRY, SOUTHWEST DETROIT, MICHIGAN USA

Historically working class, racially diverse communities, such as Delray in southeast Michigan, depended heavily on industrial jobs from nearby factories. Traditionally the housing for workers was often built in and around nearby factories which have left behind communities like Delray with extensive air and soil pollution. Over the years, substance abuse, high crime rates, and large percentages of high-school and labor-force drop outs have become pervasive issues within the Delray community. Although Delray experiences high unemployment rates and extensive poverty there is a threat to public health from Pb, Hg, As, and Cr [VI] in the soil which has become a significant source of concern. In addition to heavy industry, many houses utilized lead based paints during their construction in the early 20^th century contributing to elevated blood Pb levels. Given the potential for a new bridge to Canada being located within the heart of Delray, an investigation into this area has included soil samples taken from residential properties. Initial analysis of approximately 400 samples has shown significant levels of Pb and As within the upper 0.1 meters of soil. The high levels of Pb and As present in the soil suggest that further investigation is needed and there is potential for remedial action prior to development. This investigation was being conducted by the University of Michigan –Dearborn in conjunction with local community groups and the Detroit Public Schools.
