Pesticide mitigation capacities of constructed wetlandsThis article is part of a larger document. View the larger document here.
This research focused on using constructed wetlands along field perimeters to buffer receiving water against potential effects of pesticides associated with storm runoff. The current study incorporated wetland mesocosm sampling following simulated runoff events using chlorpyrifos, atrazine, and metolachlor. Through this data collection and simple model analysis, researchers conservatively predicted wetland buffer travel distances necessary to mitigate potential pesticide effects on receiving systems, which ranged from 100 to 400 m for the pesticides. This research provides fundamental answers concerning the use of constructed wetlands for pesticide mitigation in agricultural watersheds.
