Basis for Assessment

The assessment of support of the Class B(LW) aquatic life uses (FST) was reviewed and approved by the DNR Fisheries Bureau.   The assessment of support of the Class C (drinking water) uses was reviewed and upgraded from PS to FST.   Average levels of atrazine are below the MCL; thus, the Class C uses were assessed as FST.
