Assessment Comments
Basis for Assessment
Used information from Miller and Kennedy (1995) to again assess support of the Class C (drinking water) uses as FST due to (1) low levels of agricultural pesticides, including atrazine and cyanazine, detected in the water and sediment of Cedar Lake and (2) lack of any pesticide levels that exceeded MCLs.
