One copy of the document is not <br />bound so it can easily be electronically scanned. These documents include environmental <br />ground water monitoring data collected and compiled during our thirty first quarter of <br />operations (June 2008). No solution mining activity occurred during the report period. <br />The ground water data summary report is spiral bound as a non-confidential document and <br />includes a comparison of the 31 st operational quarter with baseline and operational <br />general statistics prior to the current reporting period. In addition, the tables provide <br />information for comparison of Ground Water Standards as provided in Regulation No. 41 <br />and Numeric Protective Levels and Early Warning Indicators as amended in TR-4. <br />Comparison of the data values with the Early Warning Indicators (EWI) and the Numeric <br />Protective Levels (NPL) indicates one value above the calculated EWI during the sample <br />period. No values flagged above NPL during the period. The June 2008 value for <br />dissolved sodium recorded from the sample collected at the alluvial well 21-5 is 517 mg/L. <br />The calculated EWI for this constituent at this point is 498 mg/L. This information is <br />discussed in more detail and a graph representing the period of record for this constituent <br />at this well is shown in the Executive Summary of the report on pages 2. <br />Should you have any questions or comments regarding this information, please contact me <br />at (970) 285-0428 or Celina Akin at (970) 285-0406. <br />Sincere y, <br />w <br />Todd Wilson <br />A- PVC/ Gc%Pkx"' <br />Delivering a Crystal Clear Advantage <br />www.americansoda.com
