Pesticide Occurrence and Temporal Distribution in Streams Draining Urban and Agricultural Basins in Georgia and Florida, 1993-94

Proceedings of the 1995 Georgia Water Resources Conference, April 11 and 12, 1995, Athens, Georgia.Six streams located in Georgia and Florida were sampled intensively from March 1993 through April 1994 to assess the occurrence and temporal distribution of pesticides in streams representative of small urban and agricultural drainage basins. A total of 25 of the 47 pesticides and pesticide degradation products analyzed were detected in samples collected from the sites. Maximum measured concentrations of most pesticides coincided with the princpal application periods in both urban and agricultural drainage basins. Existing standards and guidelines for pesticides in drinking water were exceeded in only 1 of 217 samples. However, in the urban drainage basins, maximum concentrations of from one to three insecticides exceeded existing guidelines for protection of aquatic life during all but one month of sample collection.Sponsored and Organized by: U.S. Geological Survey, Georgia Department of Natural Resources, The University of Georgia, Georgia State University, Georgia Institute of TechnologyThis book was published by the Carl Vinson Institute of Government, The University of Georgia, Athens, Georgia 30602 with partial funding provided by the U.S. Department of Interior, Geological Survey, through the Georgia Water Research Institute as authorized by the Water Resources Research Act of 1990 (P.L. 101-397).
