Assessment Comments
USGS/NAWQA fish tissue and water quality monitoring near Tripoli.
Basis for Assessment
SUMMARY: The Class B(WW) aquatic life uses were assessed as "fully supported;" the fish consumption uses remain assessed as "fully supported." EXPLANATION: Results of monitoring conducted on the Wapsipinicon River near Tripoli from March 1996 to September 1998 by USGS as part of the National Water Quality Assessment Program (NAWQA) (eastern Iowa river basins study unit, station 05420680) showed (1) no violations of Class B(WW) water quality criteria for pH, dissolved oxygen, or ammonia-nitrogen in the 36 samples collected and (2) no violations of Class B(WW) criteria for toxic organic compounds or pesticides in the 22 samples analyzed. This lack of violations suggests "full support" of the Class B(WW) aquatic life uses. Fish consumption uses remain assessed as "fully supported" based on results of the USGS/NAWQA fish tissue monitoring in September 1995 that showed levels of organochlorine contaminants in the composite sample of whole fish white sucker was less than ½ of the respective FDA action levels and DNR levels of concern (see assessment for the 1998 report above).
