Technical Abstract: Water quality surveys have detected numerous pesticides in rivers and tributaries of agricultural and urban areas. The intense use of pesticides in agriculture and highly managed turf systems is of concern due to their potential adverse effects on the quality of surface waters, impacting sensitive aquatic ecosystems and drinking water resources. Although in most conditions, the average annual concentrations of pesticides measured in surface waters are below health-based limits, concentrations may briefly exceed these limits during runoff from the first storms after application of pesticides. Field research quantifying pesticide transport with runoff from agricultural and non-agricultural systems and the evaluation of management practices to mitigate chemical transport will be discussed. Identifying practices that reduce off-site transport of applied chemicals will increase pesticides efficacy at the intended sites of application and will also minimize their potential adverse impacts to the surrounding surface water resources.
