Abstract/Contents:"Data generated by the US Geological Survey's NAWQA program have indicated that pesticides are often detected at higher concentrations and frequencies in waterways draining suburban settings than in agricultural systems. Most of these pesticides are associatied with turf use patterns. Regulatory exposure assessments for pesticide movement to aquatic systems often make use of computer models. Due to the lack of data on turf, the model scenarios used for estimating leaching and runoff are based off of scenarios calibrated in agricultural settings. Model calibration and validation is being conducted on fairways and greens at two North Atlanta Country Clubs as a collaborative effort between UGA and industry scientists as well as modelers at USEPA/OPP and the original model developers. The US EPA has expressed a desire to have calibrated and validated turfgrass computer scenarios using their regulatory models (PRZM3/EXAMS) to obtain the best exposure estimates possible for turfgrass compounds. The goal of this research is the development of computer model scenarios calibrated on turf grass that can be used by regulatory authorities to estimate movement of turf pesticides to potential sources of drinkng water and other aquatic environments. Ultimately this research will allow regulatory authorities to make the best decisions based upon the best available science."
