| Abstract: | Current inventories of hazardous waste sites seldom include older, unreported sites, thereby creating a serious shortcoming in attempts to assess risks posed by one type of technological hazard. Based upon a review of urban morphogenesis, hazardous material use in industry, and past waste management practices, this paper presents a model of historical hazards accumulations. Reviews of past industrial waste disposal practices in three Illinois urban settings illustrate the model's effectiveness. |
