• The TSS values ranges from less than 2 to 172 mg/I. The flow ranged from 0 to 1454 gpm. During the <br />years from 1982 through 1984, TDS values were relatively low; however, from 1985 to the present the <br />TDS concentrations were higher and more similar to the 1981 values. pH values showed no noticeable <br />trends. <br />The concentrations of the parameters at site 005 were signficantly lower than the sites discussed above. <br />The TDS concentrations ranged from 190 to 1042 mg/I with an average concentration of 825 mg/1. <br />Accordingly, the conductively values ranged from 384 to 1350 micromhos/cm with the few higher values <br />occurring during 1988. TSS concentrations ranged between less than 4 and 130 mg/I. The range of <br />discharges for this period was compareble to site 001. Flow measurements ranged from 0 to 2960 gpm. <br />pH and other parameters showed no general trend during this period. <br />Site 007, during this period, had a range of measured TDS concentrations of between 95 and 888 mg/1 <br />with an average concentration of 428 mg/I. The flow ranged from 0 to 80 gpm and the TSS values <br />ranged between less than 4 to 2552 mg/I. Some high pH values occurred in periods of no flow; however, <br />these values became acceptable when flow resumed. No trends with time of the concentrations were <br />apparent during this period. <br />Site 008 water quality was similar to that at site 007. The range of TDS concentrations was between 35 <br />and 1980 mg/I welh an average of 645 mg/I. Conductively range between 181 and 2790 micromhos/cm. <br />• Flow ranged from 0 to 71 gpm and TSS was measured welhin a range of less than 4 to 1500 mg/I. The <br />limited data indicates an increasing concentration of TDS with time at this location; however, some values <br />were low in the later part of the period. pH increased slightly during this period, but was well within <br />acceptable limits. <br />Addelional operational surface water qualely data through 1996 can be found in Trapper's Annual Reports <br />(Appendix W, Volumes 17-26, Section 2) to the Division. <br />• <br />4-222b <br />PR-~} <br />MAY 1 3 1998 <br />
