摘要

Plant-protection compounds are often necessary to maintain the value and aesthetics of high value turf grass. However, these products can enter aquatic systems either by direct or indirect means. In order to better understand the possible frequency and magnitude of exposure to drinking water systems, golf courses were identified within watersheds that have historically been treated with vinclozolin fungicide. Golf courses selected in this work were chosen based on their geographic distribution, representation of the product use area, and course position in a watershed relative to a surface water intake(s). Additionally, wells were identified adjacent to courses treated with vinclozolin so that the extent of possible exposure to ground water could also be determined. Analytical results from the study were then compared via several exposure estimation methods to evaluate the ability of the modeling methodologies to predict concentrations found in drinking water based on monitoring data. Results from this examination indicate that exposure estimates based on models can overpredict concentrations found in water by several orders of magnitude.
