Evaluation of the magnitude and significance of pollution loading from urban storm water runoff, Ontario / by Richard H. Sullivan [and five others]. : En40-971/1977E-PDF

"An assessment has been made of the magnitude and significance of the pollution loadings from urban runoff from the province of Ontario. The study was conducted under the provisions of the Canada-Ontario and Canada-United States Agreement on Great Lakes and Water Quality. The selected local authorities were interviewed to obtain detailed local data. In addition various maps and demographic information were supplied by the Ministry of the Environment. Methodology used by the American Public Works Association and the University of Florida for a study of similar problems in the United States provided a basis for data manipulation and preparation of cost estimates, modified where possible to reflect conditions relevant toOntario. The cost estimate performed indicated that to obtain 25 percent control of BOD, an annual cost of $10,861,000 would be incurred. These costs are exclusive of the storm flow conveyance system. For BOD control at 75 percent, the annual cost would be $95,471,000. This report is submitted by the American Public Works Association, in partial fulfillment of Contract SS02. KE204-4-EP93, between The Department of the Environment and the American Public Works Association"--Abstract, page i.
