Assessment Comments
Assessment is based on results of USGS/NAWQA monitoring at Wapello.
Basis for Assessment
With only data from 1992 available from USGS, have 2 of 4 samples collected at average flows that have levels of fecals that exceed the Class A WQC; thus, due to lack of complete data, use BPJ to assess as PS. No problems with ammonia or DO; thus, assess support of Class B uses as FST (due to known threats from ag. NPS. All fish contams in 1991 RAFT sample were < 1/2 FDA action levels; thus, fish consumption uses assessed as FS.
