Basis for Assessment
5 of 7 samples collected at approx average flows exceeded Class A WQC for fecal coliforms. Due to lack of complete data, use PBJ to assess support of Class A use as PS. Class C use was assessed as PS: 25 of 63 samples contained NO3 at > 10 mg/l, but mean NO3 level was 8.7 (=FS). Installation of nitrate removal system by city of Des Moines, however, suggests that Class C uses should be assessed as PS.
