Short Answer

From "Historical Context and Hazard Waste Facility Siting: Understanding Temporal Patterns in Michigan" by Robin Saha and Paul Mohai
The authors provide a changing historical account of the development of public environmental concern about hazardous waste sites, delineating three periods characterized by changing public concern, legal standing/responsibility for the siting of hazardous waste, and political participation in movements to structure the siting of hazardous waste. The authors maintain that varying levels of concern and participation in conjunction with changing legal responsibility for siting and the evolving dynamics of deindustrialization led to racial and class discrimination in the siting of waste.
-What do the authors mean when they say the siting of hazardous waste sites has increasingly become "discriminatory"?
