2. Review the data report. Confirm that titles, labels, column headings, and footnotes <br />are accurate and complete. Confirm that constituents are reported in propel <br />units. <br />3. Review the date and time documentation. Confirm that the sample dates and times are <br />consistent with the date and time received in the laboratory. Confirm that the <br />dates and time fox analysis are consistent with the dates and times of the <br />analysis. Confirm that the holding times were not violated, based on a <br />comparison of sampling and analysis date and times. <br />Step 2 <br />]. Review valuer reported as None Detected. Confirm that the analytical detection limits <br />axe low enough to accomplish project goals. Confirm that all values axe either <br />reported as values ox less than the detection limit Confirm that the detection <br />limit is used consistently on all samples. <br />Step 3 <br />' 1. Review data fm-internal conrirtency. Confirm that values have a logical relationship <br />to one another. Confirm that values are within the historical range of data for a <br />' given site and constituent Confirm that values vary logically according to <br />known geologic conditions. <br />' 2. Review the internal and external gualzty contend rerultr. Confirm that spike recovery <br />percentages on matrix spikes, relative percent difference on laboratory <br />duplicates, and percent error on known laboratory standards were within <br />' acceptance limits. Confirm that digestion blanks, reagent blanks, and method <br />blanks do not contain concentrations of analyte that interfere with <br />interpretation of data. <br />5.6 Reporting <br />' Fox data evaluation and storage, the data collected, including recorded field parameters, will be <br />transferred to a computerized database (Excel) after being validated. This will facilitate data <br />' evaluation, reporting, graphic demonstration, and statistical analysis. After the results are reviewed <br />internally for quality control, data will be made available to the DMG. <br />1 <br />P:\Dan\GEN\FS-P-T\22421\Permhdng\gdpuhdon Ropome\Groundwartr Sampling Plan\Gondidon 1 Gmundwattr Svnpling Plan 3_29 OJ.doc l2 <br />
