Test for total suspended solids, total dissolved solids, <br />and iron once a month for Outfall 001 and Outfall 007. <br />(4) Measure water conductivity, PH, temperature, oillgrease, settleable solids, total suspended solids, total <br />dissolved solids, and iron. Full suite laboratory analysis (February, May, August, and November on <br />quarterly schedule), if pond(s) are discharging for Outfalls 001 through 007. <br />(5) Measure water conductivity, PH, temperature, oil/grease, and flowldepth. Have full suite laboratory <br />analysis February and August for Semi-Annual schedule and August for Annual schedule) for listed <br />groundwater monitoring wells and surface monitoring stations. <br />(6) Measure monthly water depth for groundwater monitoring wells (GWs). <br />(7) Measure annually water depth for groundwater, revert bade to monthly if water is found. <br />(Revised 4596) <br />2.04.7-39 <br />
