| Abstract/Contents: | "Urban runoff contributes approximately 10% of the non-point source pollution to our water resources. Potential contaminants include pesticides used for lawn care. While several studies have shown turf areas likely contribute negligible amounts of contaminated runoff, pesticides inadvertently applied to impervious surfaces such as driveways may be a more significant source. Our objective was to compare the potential for retail (pendimethalin) and professional (prodiamine) types of postemergence herbicides to contaminate runoff from concrete and turf surfaces. Products were applied at label rates twice over the course of two years to concrete and turf field plots on a 6% slope, then irrigated within 24 hours to cause runoff from at least the paved surfaces. Runoff water from all natural precipitation and/or irrigation events were measured over 23 months, and samples collected for pesticide residue using liquid chromatography/mass spectrometer/mass spectrometer. Turf surfaces had approximately seven to nine percent of the total runoff in each of the two years of that collected from concrete. Between 57% (year 1) and 92% (year 2) of the total runoff from turf occurred in winter/early spring while the ground was frozen. Runoff from concrete had 1.1x10-8% (198.2 μg m-2) of pesticide applied during 2000 and 4.3x10-3% (860.5 μg m-2) during 2001. Turf runoff yielded 5.1x10-8% (8.7x10-3 μg m-2) and 6.1x10-8% (1.0x10-2 μg m-2) in 2000 and 2001, respectively. The differences in pesticide runoff were statistically different (P<0.05) in 2001 but not 2000. There were no statistically significant differences in the amount or percent of prodiamine or pendimethalin in runoff, ranging from 9.9x10-6% to 4.3x10-3% (7.9 μg m-2 of prodiamine and 860.5 μg m-2 of pendimethalin, respectively) of active ingredient applied. Our results indicate application of granular formulations of prodiamine and pendimethalin to both paved and turf surfaces result in negligible amounts, e.g., <0.005% from concrete and <1x10-7% from turf, of the pesticide leaving the target area in runoff." |
