Agricultural runoff is one of the largest sources of pollution in the nation’s waterways. In recent years, scientific journals and the media have been filled with reports of toxic algae blooms and dead zones near and far: The Everglades, Great Lakes, Gulf of Mexico, Chesapeake Bay, and San Francisco Bay-Delta. Agricultural pollution also threatens public health in communities that rely on tainted groundwater. In California alone, more than a quarter million residents in largely agricultural areas are served by water systems with degraded groundwater quality.
