Trend line analysis determined only one <br />possible relevant correlation over time, TDS. Since 2006, the values for TDS have been <br />fairly stable, generally hovering between 1500 and 1700 mg/l. These values are very <br />close to the overall mean of the data set for the monitoring period. <br />MT -95 -02 Well: <br />Parameter <br />Mean <br />Std <br />dev <br />Range <br />Max. <br />Min. <br />Max at <br />Min at <br />Lab pH <br />7.87 <br />0.21 <br />0.80 <br />8.20 <br />7.40 <br />05/21/13 <br />11/10/08 <br />Lab Cond. <br />2620.00 <br />207.01 <br />790 <br />2860 <br />2070 <br />06/03/09 <br />05105110 <br />TDS <br />2178.33 <br />84.12 <br />310 <br />2330 <br />2020 <br />03/17/09 <br />08/17/11 <br />Sulfate <br />880.65 <br />80.11 <br />332 <br />1090 <br />758 <br />08/02/12 <br />05/14/12 <br />Calcium <br />210.75 <br />21.64 <br />110 <br />231 <br />121 <br />03/17/09 <br />11 /10 /11 <br />Iron <br />0.05 <br />0.00 <br />0.01 <br />0.06 <br />0.05 <br />11/10/08 <br />11/02/09 <br />Magnesium <br />199.25 <br />14.53 <br />72 <br />219 <br />147 <br />03/17/09 <br />11 /10 /11 <br />Sodium <br />154.88 <br />17.94 <br />87 <br />181 <br />94 <br />03/13/12 <br />08/13/08 <br />Elevation <br />6435.23 <br />0.82 <br />3.26 <br />6437.87 <br />6434.61 <br />05/03/11 <br />08/02/12 <br />Page 2 -7 <br />
