From this study, the Illinois EPA developed TMDL allocations for various pollutants. The report concluded that significant reductions in biochemical oxygen demand (BOD) and ammonia would be necessary in order for the Illinois Dissolved Oxygen (DO) standards to be achieved in Salt Creek during low-flow, warm conditions, and that the potential removal of one or more existing dams along lower Salt Creek could offer significant water quality improvements. Since the publication of the TMDL report, affected communities, municipal wastewater treatment plant operators, and interested environmental organizations have joined together to form the DuPage River Salt Creek Workgroup (DRSCW). The mission of the DRSCW is to study the East and West Branches DuPage River and Salt Creek watersheds in order to gain a better understanding of environmental impairments that are leading to poor water quality and impacting aquatic life. The initial focus of the DRSCW, for this project, was to develop a computer model that would accurately reflect low-flow, warm stream conditions, particularly DO, along Salt Creek, from which alternatives for improving DO concentrations could be developed. While working on this task it became apparent that better environmental monitoring data were needed. At this point the focus of the Workgroup expanded to include design and implementation of water quality monitoring studies that would generate sound scientific data. | | | | Date Created: | 09 28 2009 | | | | Agency ID: | | | | | ISL ID: | 000000041046 Original UID: 21107 FIRST WORD: Stream | |
