In earlier work under the sponsorship of EPA, a screening methodology was produced by Tetra Tech, Inc., for assessing water quality problems in areas not covered under Section 208 of the Federal Water Pollution Control Act Amendments of 1972, and loading functions were developed by Midwest Research Institute (MRI) for estimating the quantities of different diffuse loads entering receiving waters from nonpoint sources. The two methods had never been applied together under realistic conditions, however, to demonstrate how the combined techniques might be used for identification of water quality problems in U.S. rivers. In this report, the successful application of the Tetra Tech-developed nondesignated 208 screening methodology under field conditions in five river basins is described, and the compatibility with the nonpoint source calculator is demonstrated.
