Cottonwood Spring was monitored in May, September and <br />• November 1988. The Cottonwood Spring TDS values were near normal <br />during 1988. The West Buzzard site had a TDS value of 1352 mg/1 <br />during May. No Name Seep was found to have a TDS of 2338 mg/1 in <br />May. <br />3.2 FIELD CONDUCTIVITY <br />The Trapper Mine Annual Hydrologic Report in the past has <br />presented only plots of the TDS values versus time. The 1988 <br />Annual Hydrologic Report has included the TDS and field <br />conductivity time plots. Some field conductivities had been <br />corrected 4or temperature when a correction should not have been <br />made due to the meter being temperature compensating. <br />Conductivity values have been corrected in this report. Most <br />• conductivity plots reflect the same changes in individual wells <br />as seen on the TDS plots with few outliers in the data. Most <br />outliers shall be attributed to field measurement error. As <br />future data is carefully collected, conductivity plots will <br />become much more definitive of trends through time. Future field <br />conductivity plots should be definitive of major constituent <br />water-quality changes. TDS measurements on an annual basis <br />should be adequate to check the conductivity results. <br />Wells GA1 and GA2 are used to monitor the OR and KLM <br />aquifers at the GA site. Figures B-39 and 8-40 present the field <br />conductivity versus time plots for wells GA1 and GA2. Well GA1 <br />exhibits a good amount of variation during individual years. The <br />overall plot of conductivity versus time for well GAI presents a <br />• slight declining trend. The June 1988 data is an outlier that is <br />3-9 <br />
