A study performed to satisfy the requirements of Section 208 of Public Law 92-500 for the nondesignated urban area of Illinois is described. The data collection program involving up to 34 constituents on both water samples and dry accumulation samples is summarized. The data are used to calibrate an urban runoff, quantity-quality model known as QUAL-ILLUDAS. The accumulation rates and composition of street surface pollutants needed in the model are determined. Model results are related to land use and other basin parameters by means of regression equations. It is concluded that water quality modeling is a useful tool and that urban runoff contains heavy metals and other constituents in excess of Illinois Water Quality Standards.
