Basis for Assessment
Used assessments of support of the Class A primary contact recreation uses (=FST) and the Class B(LW) aquatic life uses (=FST) developed for the 1994 report. In addition, used results of fish tissue monitoring conducted for the 1994 RAFT to assess support of fish consumption uses as FS: levels of all contaminants in composite samples of channel catfish and largemouth bass were less than one-half of FDA action levels (=FS).
