"Increasing urbanization and the demand for high quality water have directed attention to the problem of combined sewer overflows, while recent research has demonstrated that stormwater alone, without the influence of sanitary sewage, carries a significant pollutional load. The purpose of this investigation was to determine the quality and pollutional contribution of stormwater runoff from a small urban area, with specific emphasis on the development of a suitable sampling and flow recording system, the characterization of runoff and the correlation of runoff quality with local environmental factors and storm characteristics. The system developed consisted of an automatic sampler capable of taking a series of stormwater samples, each representing a runoff period varying from 5 min to 2 hr in duration, a flow recorder, and the necessary ancillary equipment to permit automatic operation. Runoff from 3 test watersheds in the Rolla area during 10 precipitation events over a 6-month period was sampled and characterized in the laboratory using physical, chemical and bacteriological determinations. The characteristics of the runoff from the small urban area were similar to those reported for runoff from large metropolitan areas. The time since the beginning of the runoff event, the length of the antecedent dry period, the average intensity of precipitation and the basin slope were found to have an effect on runoff quality"--Abstract, page ii.
