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-sixth quarter of <br />operations (September 2009). No solution mining activity occurred during the report <br />period. <br />The ground water data summary report is spiral bound as a non-confidential document and <br />includes a comparison of the 36th 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 no values above the calculated EWI or NPL during the <br />sample period. <br />Annual surveying of the well field subsidence bench markers was completed during the <br />quarter. The data for the baseline elevations is plotted with the data measured in 2009. <br />The data overlaps indicating no significant change in the elevations of the bench mark <br />monitoring points. The well field subsidence data is represented in the following chart. <br />Delivering a Crystal Clear Advantage <br />www.americansoda.com
