Book excerpt: A study of a small, unnamed tributary of the Olentangy River, Franklin County, Ohio, shows the role of storm events in controlling solute concentrations in the stream water, the hyporheic zone and the runoff within the watershed. The stream, located in Columbus, Ohio, is hosted in the Devonian Columbus limestone and the overlying glacial till. The first order stream, with a watershed of 4.07 square kilometers in area, hosts a variety of landuses, including open fields, forests, residential areas, parks and the Ohio State University's airport. Collection of samples during both storm events and stream baseflow conditions were analyzed for major cations and anions, nutrients, reactive silica, dissolved organic carbon, total suspended solids, pH and titration alkalinity. The mean concentration of dissolved organic carbon was 5.25 mg/L for the hyporheic zone and 4.02 mg/L for the surface water. Stream water showed significantly higher concentrations of fluoride, strontium, sulfate, potassium and magnesium when compared to the surface runoff. The primary control of these ions is due to the limestone bedrock. Organic carbon concentrations decreased in the hyporheic zone during storm events, but increased in the stream water. This observation suggests that the hyporheic zone is the source for organic carbon to the stream water. All other constituents analyzed were consistent throughout the entire stud
