Abstract
The environmental impact of agrichemical contamination of surface and ground water is a special concern in the Midwest. Better chemical management alone will not sufficiently reduce negative impacts on the environment. Another strategy—restoring wetlands in agricultural watersheds to serve as sinks for these chemicals—holds additional promise for reducing this contamination.
