BMPs in the Heartland: An Institutional Framework for Stormwater Management

The particle size distributions of stormwater at different locations in an urban area greatly affect the ability of different source area and inlet controls in reducing the discharge of stormwater pollutants. A series of U.S. EPA funded research projects has examined the sources and treatability of urban stormwater pollutants (Pitt, et al. 1995). This research has included particle size analyses of 121 stormwater inlet samples from three states (southern New Jersey, Birmingham, Alabama; and at several cities in Wisconsin) that were not affected by stormwater controls.
