Pesticides are used extensively in the largely agricultural Red River of the North (Red River) Basin, but, unlike many other agricultural basins, only small amounts are routinely detected in samples from streams in the basin. The pesticides detected comprise less than 2 percent of the amount applied and usually are at concentrations far less than established drinking water standards. Most of the detected pesticides seem to come from sources near the headwaters in the southern part of the basin. Although low, concentrations are related to pesticide application and runoff. Flat slope, organic solids, pesticide management, and degra- dation all may reduce pesticide contamination of Red River streams.
