         WQ: 2002 Diazinon First Flush Results | 
     
 
 
    | 
   Caption:  The results above show the range of values for the pesticide diazinon in nanograms per liter (ng/L) taken as part of the First Flush Russian River monitoring effort in 2002. The data represent only the first sample taken at each site for the purposes of comparison.  While samples were collected by volunteers,U.S. Environmental Protection Agency staff worked up lab results using the enzyme-linked immunoabsorbant (ELISA) method. While the highest values were on Foss Creek in downtown Healdsburg, Cotati Creek also had a very elevated reading. For more information on methods and a link to protocols and reports, see InfoLinks.
