Abstract |
The Illinois Environmental Protection Agency was one of a number of agencies which participated in the United States Environmental Protection Agency's Nationwide Urban Runoff Program (NURP). NURP consisted of 28 projects which evaluated the type and extent of urban runoff problems, impacts of urban runoff on receiving waters and the effectiveness of control practices. The work reported in this document is the component of the study which assessed the impacts of urban runoff on the receiving stream. The objective of this study was to evaluate the effects of urban runoff on the biota of both the urban receiving stream, Boneyard Creek, and the agricultural stream into which it flows, the Saline Branch Drainage Ditch. Fish and macroinvertebrate communities were sampled upstream and downstream from Champaign-Urbana area. Chlorophyll samples were collected upstream and downstream of the urban area. |
