   Caption:  This chart shows the minimum, median, and maximum total Kjeldahl (organic) Nitrogen in the Laguna de Santa Rosa at Trenton Bridge for the period 1973-2000.  Treated municipal wastewater from the city of Santa Rosa and surrounding areas is discharged in the Laguna.  Kjeldahl Nitrogen was sampled 50-100 times per year in the mid-1970's, but only occasionally in the 1980's and 1990's.  Data were provided by the North Coast Regional Water Quality Control Board (NCRWQCB).  See InfoLinks for more information.
