Assessment Comments
Basis for Assessment
Class B uses were assessed as NS due to fish consumption advisory issued in Dec 89 due to chlordane (although ISU monitoring in 90 and 91 showed very low levels of all contams); Class A assessed as FST due to only one violation in 20 samples (a very low frequency of violations in Iowa rivers); Class C assessed as NS due to drinking water advisories issued by city of Des Moines due to high nitrate; at 430051, 21 of 76 sampled exceeded 10 mg/l w/ mean of 6.1 (=FS).
