This report provides an initial assessment of the magnitude of nonpoint sources of water pollution in the Dallas/Fort Worth Designated Planning Area. This presentation is intended to provide a perspective regarding the relative magnitude of the various major nonpoint sources and the relative importance of these nonpoint sources when compared with point sources in the area. Three major nonpoint source categories are emphasized: runoff from urban areas, runoff from grassland, and runoff from cropland. The four major pollutants of concern are five-day biochemical oxygen demand, total nitrogen, total phosphorus, and sediment.
