(1)- Measure water conductivity, PH, temperature, flow\depth.
(2)- Measure monthly for conductivity, PH, temperature, oil\grease, settleable solids,
' total suspended solids, total dissolved solids, and iron for all discharging water
from ponds.
(3)- Measure weekly for conductivity, PH, temperature, oil\grease, settleable solids, and
flow for all discharging water from ponds. Test for total suspended eolide, total
dissolved solids, and iron once a month.
(4)- Measure water conductivity, PH, temperature, oil\grease, settleable solids, total
suspended eolide, total dissolved eolide, and iron. Full suite laboratory analysis
(TABLE 2.04.7-2), (February, May, August, and November on quarterly schedule), if
pond(s) are discharging.
(5)- Measure water conductivity, PH, temperature, oil\grease, and flow\depth. Have full
suite laboratory analysis (TABLE 2.04.7-2), (February, May, Auqust, and November on
quarterly schedule and May and November for Semi-Annual schedule).
(6)-Measure water depth.
