GW -N3 Well <br />GW -N3 monitors the underburden aquifer adjacent to the New Horizon 1 mine area. The GW - <br />N3 well is located north of Tuttle Draw and north of the New Horizon permit area. <br />Summary of the indicator parameters for GW -N3 is provided as follows: <br />A review of the water year for this well indicates no minimum or maximums occur during the <br />water year. As shown on the graphs for indicator parameters, the majority of the indicator <br />parameters are trending down. Sampling results indicate normal seasonal fluctuations. <br />9 1 P a g e <br />7.6 <br />0.2" <br />0.7 <br />8;0 : <br />7.3 <br />�$ ' <br />5/14/08 <br />Lab Coad.
