To assess urban storm water quality characteristics in the metropolitan area of Columbus, Ohio, two drainage basins were equipped with automatic water quality samplers, monitors, rain gages, and stream gages. Over a two year period samples from the two basins were analyzed for 46 chemical quality parameters. The analysis of the data followed three approaches. First the constituent concentrations were analyzed and compared with Ohio EPA warm-water habitat standards. The results of this showed high levels of copper, iron, lead, and zinc. The second approach was bivariate correlations and regression analysis. This approach yielded information about relationships between constituents but had few uses. The third approach was the use of multiple regression analysis to relate storm yields to rainfall characteristics. In general, the results indicated that the storm yields are dependent on antecedent conditions of the storm.
