Water Quality in the Sugar Creek Basin, Bloomington and Normal, Illinois

Water-Resources Investigations Report 78-78
Prepared in cooperation with Bloomington and Normal Sanitary District



Sugar Creek, within the twin cities of Bloomington and Normal, Illinois, has differences in water quantity and quality as a result of urban runoff and overflows from combined sewers.

Water-quality data from five primary and eight secondary locations showed three basic types of responses to climatic and hydrologic stresses. Stream temperatures and concentrations of dissolved oxygen, ammonia nitrogen, total phosphorus, biochemical oxygen demand, and fecal bacteria showed seasonal variations. Conductivity (dis­solved solids), pH, chloride, and suspended solids concentrations varied more closely with stream discharges. Total organic carbon, total nitrogen, total phosphorus, biochemical oxygen demand, and fecal coliform and fecal strep­tococcal bacteria concentrations exhibited variations indicative of initial flushing action during storm runoff.

Selected analyses for herbicides, insecticides, and other complex organic compounds in solution and in bed material showed that these constituents were coming from sources other than the municipal sanitary treatment plant effluent. Analyses for 10 common metals: arsenic, cadmium, chromium, copper, iron, lead, manganese, mer­cury, nickel, and zinc showed changes in concentrations below the municipal sanitary plant outfall.
