Assessment Comments
Assessment is based on results of DNR ambient monthly monitoring near St. Joseph.
Basis for Assessment
Had no violations of Class B(WW) WQ criteria for conventional pollutants in the 24 samples collected during the 1996-97 period. The only violation of Class B(WW) WQ criteria for toxics is the June 1995 violation of TRC; this was the only violation in 36 samples analyzed for TRC from 1995-97 (see above account for the 1996 report). Section 305(b) guidelines allow one violation of an acute/chronic WQ criterion in an abundant data set (more than 10 samples) for waters assessed as fully supporting (see p. 3-18 of the 1998 Section 305(b) guidelines). Continue to use the assessment of support of fish consumption uses developed for the 1996 report (=FS); i.e., all contaminants were less than 1/2 FDA action levels.
