Paragon Analytics <br />INORGANICS CASE NARRATIVE <br />CEMEX, Inc. <br />A + C Pits <br />Order Number - 0508300 <br />1. This report consists of 4 water samples, <br />2. The samples were received intact on 08/31/05. The temperature of the samples <br />upon receipt was ambient. <br />3. The samples were prepazed for analysis based on Methods for the Chemical <br />Analysis of Waters and Wastes (MCAWVi~, May 1994 procedures. <br />4. The samples were analyzed following MCAWW procedures for the following <br />methods: <br />Anal e Method SOP # <br />pH 150.1 1126 Rev 15 <br />Specific conductance 120.1 1128 Rev 8 <br />TSS 160.2 1100 Rev 8 <br />5. All standards and solutions were used within their recommended shelf life. <br />6. The samples were prepazed and analyzed within the established hold time for each <br />analysis. <br />All in house quality control procedures were followed, as described below. <br />7. General quality control procedures. <br />^ A preparation (method) blank and laboratory control sample (LCS) were <br />prepared and analyzed with the samples in each applicable prepazation batch. <br />There were not more than 20 samples in each prepazation batch. <br />^ The method blank associated with each applicable batch was below the <br />reporting limit for the requested analytes. This indicates that no contaminants <br />were introduced to the samples during prepazation and analysis. <br />^ The LCS was within the acceptance limits for each applicable analysis. <br />^ All initial and continuing calibration verifications (ICV/CCV) associated with <br />each applicable analytical batch were within the acceptance criteria for the <br />
