Summary

Potential Pesticide Runoff from Cropland

Pesticide concentrations exceeded one or more human-health benchmarks in about 10 percent of agricultural streams examined by USGS as part of the National Water Quality Assessment Program, and in about 1 percent of sampled wells used for drinking water in agricultural areas.

Watersheds with a high propensity to discharge pesticides to surface water are located primarily in the Heartland and Mississippi Portal regions. Watersheds with a high propensity to discharge pesticides to ground water are primarily in the Heartland, Prairie Gateway, and Southern Seaboard regions.
