The Little Arkansas River originates in areas of high agriculture use and flows to areas of increasing population and urbanization. As the urbanization increases especially between Valley Center KS and Wichita KS the health of the river is degraded and 303d listed endangering aquatic life and limiting resource use. Using EPA collected data for statistical analysis to determine parameters of interest heavy metal concentrations will be determined and linked to a visual site analysis. From the results, amount of degradation can be determined and related to past samples indicating danger to aquatic life and resource limitations for anthropogenic use. Research is continuing to determine spatial concentrations of trace metals and sediment with differing stream discharge related to urbanization.
