| Abstract/Contents: | "There has been increased focus on turf pesticides since the early 1990s due to the intense public scrutiny proposed golf courses receive during the local permitting process, as well as pesticide registration evaluations by the U.S. Environmental Protection Agency under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). Results from permit-driven studies are frequently not published and knowledge about them is usually not widespread. The purpose of this study was to comprehensively evaluate available golf course water quality data and assess the extent of impacts as determined by comparisons with toxicological and ecological reference points. Results of this study include: Forty-four studies involving 80 courses from a 20-year period passed our quality control and other review criteria. A total of 38,827 data entries (where one analysis for one substance in one sample equals a data entry) from pesticide, pesticide metabolite, total phosphorus, and nitrate analyses of surface water and ground water were evaluated. Analytes included 161 turf-related pesticides and pesticide metabolites. Widespread or repeated water quality impacts by golf courses did not occur at the sites studied, although concerns are raised herein about phosphorus. Individual pesticide database entries that exceed toxicity reference points for ground water and surface water are 0.15% and 0.56%, respectively. Pesticides detected in wells had longer soil metabolism half-lives (49 days) compared with those not detected (22 days), although the means were not significantly different. The maximum contaminant level (MCL; 10 mg/L) for nitrate-nitrogen was exceeded in 16/1,683 (0.95%) of the ground water samples. There were 1,236 exceedances out of 1,429 data entries (86.5%) of the total phosphorus ecoregional criteria in five ecoregions, although many of these exceedances arose from storm events. Thus, phosphorus appears to present the greatest water quality problem in these studies." |
