• <br />• <br />Water Quality Monitoring Plan Climax Molybdenum Company <br />Version: R 1 Permit No. M -1977 -493 <br />• Sample preparation method references; <br />• Date and time of analysis; <br />• Analytical method references; <br />• Analytical result for each parameter requested, including results from QA/QC <br />samples; <br />• Unit of measurement; <br />• Method detection limit (in units of sample results); <br />• Laboratory quantification or reporting limit (defined); <br />• Calibration verification results; <br />• Theoretical concentrations for laboratory control samples, if used; <br />• Method blank results; <br />• Results of laboratory QC analyses [laboratory control sample /laboratory control <br />sample duplicate (LCS /LCSD); matrix spike /matrix pike duplicate samples <br />(MS /MSD); analytical duplicate, etc.] associated with each batch of samples <br />analyzed, as appropriate to the method protocol; <br />• Definition /explanation of any internal data qualifiers applied, and; <br />• A brief narrative describing sample analyses including description of any problems or <br />unusual circumstances during analysis. <br />6.3.4 Data Evaluation <br />All data shall be evaluated according to the following procedures to ensure that only data of <br />appropriate quality are used to evaluate site groundwater conditions. <br />6.3.4.1 Field Measurements <br />Field measurements including pH, specific conductance, and temperature will be collected <br />during monitoring activities. The field data will be reviewed in an attempt to identify any <br />transcriptional or computational errors. <br />6.3.4.2 Laboratory Data <br />Laboratory calculations and data review shall be performed by the laboratory in accordance with <br />the procedures described by the analytical method. The laboratory review shall include the <br />results of the QC analyses, instrument calibration, and maintenance records, calculations, and <br />the chain of custody record and analytical holding times. The laboratory will prepare a case <br />narrative to summarize the findings of their review, noting any problems associated with the <br />analysis of the field samples. <br />After receipt of the data from the laboratory, data evaluation shall be performed to: <br />• Ensure that the analytical laboratory was operating in control at the time the samples <br />were analyzed and to document that appropriate methods and holding times were <br />observed; <br />EPP — Appendix C <br />August, 2011 24 <br />
