1State standard for alkalinity currently unavailable. The Environmental Protection Agencycurrently recommends a minimum of 20.0 mg/L (USEPA 1999).
2 Based on maximum chronic and acute standards for cold-water fishery. Levels are pH and temperature dependent. The maximum acute value at 4° C and pH of 6.6 is 32.1 mg/l. The maximum acute value at 30° C and pH of 9.0 is 0.6 mg/l. The maximum chronic value at 4° C and pH of 6.6 is 2.4 mg/l. The maximum chronic value at 30° C and pH of 9.0 is 0.1 mg/l. For specific criteria at varying pH and temperatures consult Table B of the Rules of the Department of Natural Resources Division 20-Clean Water Commission Chapter 7- Water Quality.
3State standard for phosphorus is currently unavailable. The Environmental Protection Agency currently recommends a maximum of 0.1mg/L for rivers (Christensen and Pope 1997).
