April 22, 1999 • <br />6.4 Data Management <br />• Page 22 <br />All analytical data reports will be tabulated within one month of receipt from the laboratory. <br />Analytical laboratory data will be sent to required agencies and made available for inspection and <br />maintained in a central job file. All records will be maintained for the life of the mine. Types of <br />records to be maintained for this project include the following: <br />- Field log books <br />- Chain-of-custody records <br />- Any discrepancy/deficiency reports <br />- Laboratory analytical reports <br />- All supporting QC information <br />6.5 Internal Quality Control Checks <br />6.5.1 Quality Contro(Checks-Field Activities <br />The quality control samples used to measure accuracy and precision affected by field <br />activities aze described in Appendix C and are summarized below: <br />Field Blanks <br />Field blanks aze samples of de-ionized or distilled water which aze submitted to the <br />laboratory for analysis. Field blanks will be collected as a quality check on sample preparation <br />technique, external contamination, and the analytical method. One blank per sampling event will <br />be analyzed using the technique described in Appendix C. Field blanks will be labeled and handled <br />as regulaz samples. <br />Equipment Rinsate Blankr <br />Equipment rinsate blanks will be collected to ensure that sampling equipment is clean and <br />that potential for cross-contamination has been minimized by the equipment decontamination <br />procedures. Using the technique described in Appendix C, one equipment rinsate blank will be <br />collected for every suite of samples which were collected utilizing decontaminated equipment. <br />Duplicates <br />Duplicate samples will be collected and submitted for laboratory analysis to allow a <br />determination of natural sample variance, consistency of field and lab techniques, and analytical <br />precision. One duplicate sample will be collected for every suite of samples using the technique <br />described in Appendix C. The duplicates will be labeled and handled as regulaz samples. <br />Agapito Associates, [ne. <br />
