Abstract

"Stormwater runoff from urban areas has long been recognized as a pollutional source, however, only in the last decade has there been an extensive eff ort to measure its effect on receiving lakes and streams. Because runoff from small urban communities has received limited attention, this investigation was undertaken to determine the quality and pollutional contribution of stormwater runoff from a small urban area. The specific objectives of the study were: to characterize and correlate runoff quality with land use activity and to qualitatively and quantitatively measure the pollutants discharged with respect to time.

Runoff from 3 test watersheds in Rolla, MO, was sampled and measured by means of a continuous, automatic sampling and flow recording system initially developed by Ford (25), and was analyzed for chemical, physical and bacteriological characteristics. The data, together with corresponding values reported by Ford, were statistically treated to establish the characteristics of the runoff over an extended period.

The runoff from the small urban area produced a significant pollutional load to the receiving streams. The watershed with poorer drainage characteristics discharged a lower pollutional load per unit area, even though poorer environmental conditions in this basin resulted in greater concentrations of pollutants. The peak concentration of constituents generally occurred during the initial flush-off period, while the peak rate of discharge occurred during the period of greatest flow. The critical period of runoff from a design viewpoint was from 15 min to 3 hr. when 90 percent of the COD, 80 percent of the TS and 80 percent of the flow were discharged"-- Abstract, p. ii
