Section 128-10.2 System Specific Water Quality Characteristics

The system specific water quality characteristics of the reservoirs and reservoir stems, as of September 1990, are set forth in Tables 1 and 2 of this Appendix. It is the intention of the Department that the system specific characteristics be maintained at the stated levels by implementation and enforcement of these rules and regulations.
