Who is conducting this study?

A local group of communities, publicly owned treatment works, and environmental organizations have come together to form the DuPage River/Salt Creek Work Group (DRSCW) to better determine the stressors to the aquatic systems through a long term water quality monitoring program and develop and implement viable implementation projects to accurately address the stressors.

The DRSCW, in conjunction with The Conservation Foundation, has contracted with HDR Engineering, Inc. to complete the Stream Dissolved Oxygen Improvement Feasibility Study for Salt Creek and East Branch of the DuPage River.

Why is this study important?

Between 1992 and 1998, Salt Creek and the East Branch of the DuPage River were listed on the Section 303(d) List of Impaired Waters by the State of Illinois. Since then, Total Maximum Daily Loadings (TMDLs) for each of these streams have been prepared by the State of Illinois and approved by USEPA. To date, only general alternatives have been considered. This project will result in specific projects to be implemented as required by the TMDL Program.
