<br />by the Clean Water Restoration Act of 1966 and the Federal Water <br />Pollution Control Act Amendments (FWPCA) of 1972 which placed <br />new and stronger emphasis on stormwater pOllution. Since the <br />early 1970's, numerous articles have been published dealing with <br />different aspects of the problem. <br /> <br />. <br /> <br />. <br /> <br />III. Stormwater Pollution Literature (Separate Sewers) <br /> <br /> <br />The major significance of urban stormwater runoff pollution <br /> <br /> <br />has been realized during the last ten years. A wide variety of <br /> <br /> <br />contaminants have been evaluated at different locations and for <br /> <br /> <br />various conditions of land use and traffic conditions. Some <br /> <br /> <br />attempts have been made at establishing relationships between <br /> <br /> <br />pollutional potential and the land use factors. Models have been <br /> <br /> <br />developed for predicting the impact of stormwater pOllution on <br /> <br /> <br />a receiving stream. Most researchers have found that the pol- <br /> <br /> <br />lutional characteristics of stormwaters are highly variable and <br /> <br /> <br />this has been a problem in the utilization of the results obtained <br /> <br /> <br />from predictive models. <br /> <br /> <br />The literature in the stormwater pOllution field is <br /> <br /> <br />becoming quite extensive and the articles discussed in this <br /> <br /> <br />report were selected for their relationship to the experimental <br /> <br /> <br />work of this study. <br /> <br /> <br />A. Concentration of Pollutants. <br /> <br /> <br />Many of the earlier studies have been summarized in EPA <br /> <br /> <br />publications and the results are shown in the following tables (1 & <br /> <br /> <br />2) . Three more recent studies have given results for a more <br /> <br /> <br />extensive list of pollutants. <br /> <br />6 <br />
