ABSTRACT
The Detroit Metropolitan area occupies much of the basin of the Detroit River - the basin as a whole is home to million people. The input data, the runoff concentrations by land use of cadmium, copper, and lead were obtained from the stormwater pollutant loading factors presented in the Rouge River National Wet Weather Demonstration Project Report. Camp Dresser and McKee developed a complete hydraulic model of the major sewer interceptors to estimate response to rainfall events and assess potential combined sewer overflow (CSO) control measures within the region tributary to the Detroit Wastewater Treatment Plant in 1993. The Industrial Waste Control database includes information only for Significant Industrial Users that are required to participate in the Industrial Pretreatment Program. Representing a design in which sewage and surface runoff combine and exceed retention and treatment system capacity, CSOs are identifiable as a troubling source of contamination for water bodies that are cumulative recipients of overflows.
