Abstract
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.
