Paragon Analytics <br />METALS CASE NARRATIVE <br />CEMEX, Inc. <br />A + C Pits <br />Order Number - 0504065 <br />1. This report consists of 2 water samples. <br />2. The samples were received cool and intact on 04/07/05. <br />3. The samples were to be analyzed for dissolved metals. The samples had not been <br />filtered and preserved prior to receipt. The samples were filtered through a 0.45 <br />micron filter and preserved with nitric acid to a pH less than two prior to analysis. <br />4. The samples were prepared for analysis based on Methods for the Determination <br />ofMetaLs in Environmental Samples -Supplement 1 procedures. <br />For analysis by ICP-MS, the samples were prepared following method 200.8 and <br />PA SOP 806 Rev. 10. The samples were not digested prior to analysis. <br />The samples were prepared for ICP-MS analysis of selenium bypassing the <br />samples and associated QC through a cation exchange column. The cation <br />exchange column removes cations from the matrix. <br />5. The samples were analyzed following Methods for the Determination of Metals in <br />Environmental Samples -Supplement 1 procedures. <br />Analysis by ICP-MS followed method 200.8 and PA SOP 827 Rev. 3. <br />The relationship between intensity and concentration for each element is <br />established using at least four standards, one of which is a blank solution. A <br />linear regression is performed by the instrument softwaze to develop the <br />calibration equation. <br />During sample analysis concentrations are computed by the softwaze and the <br />results are printed in ug/L,. The validity of the calibration equation is tested by <br />analyzing the following solutions: a blank, a low level check solution with <br />concentrations near the reporting limit, an Initial Calibration Verification (ICV) <br />standard from a 2"d source standard solution with concentrations near the <br />middle of the analytical range, a Continuing Calibration Verification (CCV) <br />standard with concentrations near the middle of the analytical Yange but <br />
