Impact Of Impervious Surfaces On Water Quality By Measurement Of Macroinvertebrates In Rock Island And Moline, Illinois, Kara Noonan

Urban Watershed Project

Streams have been degrading in quality since the introduction of impervious surfaces. Water concentrations have been altered as sediment and other pollutants have been introduced from severe erosion from runoff. As the water continues to change, the biotic integrity becomes disturbed. More specifically, aquatic invertebrate populations begin to change. More organisms that can tolerate poor quality streams are thriving as organisms that can only tolerate high quality streams are beginning to run thin. This study strives to find a spatial relationship between impervious surfaces around Rock Island and Moline, Illinois and the water quality within the streams by looking at …
