Technical Abstract: Pesticides associated with the turfgrass industry have been detected in storm runoff and surface waters of urban watersheds; inferring contaminant contributions from residential, urban, and recreational sources. Golf course turf often requires multiple applications of pesticides at rates that exceed those typically found in agricultural or home environments. The objective of this study was to quantify fungicides transported in snowmelt and rainfall runoff from creeping bentgrass turf managed as a golf course fairway. Chemographs from rainfall runoff occuring within days of fungicide application showed fungicides in the initial runoff and throughout the runoff event. Snow melt collected almost four months after fungicide application also contained fungicides and a degradation product. Loads of fungicides measured in the edge-of-turf runoff were used to calculated estimated environmental concentrations of fungicides anticipated to occur in surface waters receiving the snowmelt and rainfall runoff, which were compared to known toxicological endpoints to evaluate environmental risk.
