         WQ: 2002 Ammonia First Flush Results | 
     
 
 
    | 
   Caption:  The results above show the range of values for ammonia as indicated by Nitrogen in milligrams per liter taken as part of the First Flush Russian River monitoring effort in 2002. The data represent only the first of three samples taken at each site.  While samples were collected by volunteers, wet chemistry with a calibration curve and a spectrophotometer were carried out by staff of the North Coast Regional Water Quality Control Board at their lab in Santa Rosa. While the highest values were on Foss Creek in downtown Healdsburg, the headwaters of Dutch Bill Creek had the second highest score. For more information on methods and a link to protocols and reports, see InfoLinks.
