Assessment Comments
Assessment is based on results of IDNR ambient monthly monitoring near Pisgah (950032 - 21IOWA/DNR).
Basis for Assessment
Also had sample with metals violations (chromium =80 ug/l > acute criterion; copper=90 ug/l > acute criterion, and lead = 60 ug/l > chronic criterion). TSS for this sample, however, were even higher (6,000 mg/l) than in the 1989 sample. Thus, assess support of Class B(WW) uses based on habitat alterations due to channelization and flow alterations and attribute the high levels of metals to high TSS in the sample (i.e., not an impairment). One of 24 samples violate DO criterion.
