Abstract

Water-quality characteristics of streams draining Topeka, Kansas , and the Shunganunga Creek basin were investigated from October , 1979, through November 1981, to determine the effects of runoff from urban areas. Characteristics were determined at six sites and summarized statistically for three streamflow conditions-dry weather, storm, and snowmelt. Median concentrations of trace metals and nutrients were greater in storm streamflow than in dry-weather streamflow. Regression equations were developed to estimate median concentrations of total lead and zinc in storm streamflow from the percentage of drainage area in residential plus commercial land-use areas and from street density. Median concentrations of dissolved sodium, chloride, and solids were considerably greater in snowmelt streamflow than in dry-weather streamflow. Regression equations were also developed to estimate median concentrations of dissolved sodium, chloride, and solids from the summation of percentages of the drainage area in residential, commercial, and industrial land-use areas and from street density. Multiple-regression analysis relating storm-runoff volumes and average constituent concentrations to land-use and storm charactersitcs produced significant relations for storm-runoff volume, total lead, total zinc, and suspended sediment.
