Test for total suspended solids, total dissolved solids, <br />and iron once a month for Outtall 001 and Outfall 007. <br />(4) Measure water conductivity, PH, temperature, oiUgrease, settleable solids, total suspended solids, total <br />dissolved solids, and iron. FuII suite laboratory anaysis (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, oiUgrease, and flow/depth. Have full sufte laboratory <br />analysis February and August for Semi-Annual schedule and August for Annual schedule) for listed <br />grourxiwater monitoring wells and surtace monitoring stations. <br />(6) Measure water depth for groundwater monitoring wells (GW s). <br />(7) Measure annually water depth for groundwater, revert hack to moMhy 'rf water is found. <br />(Rev. 9/95) 2.04.7-32 <br />
