Step 2 <br />Step 3 <br />5.6 Reporting <br />2. Review the data report. Confirm that titles, labels, column headings, and footnotes <br />are accurate and complete. Confirm that constituents are reported in proper <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 for 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 />1. Review values reported as None Detected. Confirm that the analytical detection limits <br />are low enough to accomplish project goals. Confirm that all values are either <br />reported as values or less than the detection limit. Confirm that the detection <br />limit is used consistently on all samples. <br />1. Review data for internal consistency. 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 quality control results. 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 />For 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 />P:\ Data\ GEN\ F -S -P -T \22421 \Permimng \Snpulation Response \Groundwater Sampling Plan \Condmon 1 Groundwater Sampling Plan 3_24_03.doc <br />12 <br />
