In 2006, the Connecticut Department of Environmental Protection issued an impervious cover (IC) Total Maximum Daily Load (TMDL) for the Eagleville Brook watershed, located on the University of Connecticut campus and the adjacent Town of Mansfield, CT. While traditional TMDLs typically target a specific pollutant, this one addresses the impacts of urban development directly by using IC as the TMDLs metric. This approach was chosen because the Eagleville Brook Watersheds biological impairment could not be attributed to any one pollutant, but rather, was ascribed to an array of pollutants transported by stormwater and linked to urbanization or, more specifically, impervious cover (IC). The existing IC in the Eagleville Brook Watershed was measured at 18.0%, but the TMDL target was set at 11% based on characteristics of similarly sized watersheds in Connecticut that had healthy macroinvertebrate populations.
