Site Assessment Report Outline • - 3 - <br /> Lithology <br /> Types of sediments encountered <br /> Presence, location, and lateral continuity of any significant sand, silt, <br /> or clay layers <br /> Any visual signs of contamination <br /> Supporting Data: <br /> Well logs geologic cross-sections should be included in the report. <br /> Analytical Results of Soil and Ground Water Sampling <br /> Analytical results of each monitoring well should be summarized <br /> Supporting Data: <br /> Laboratory analytical sheets <br /> Chain-of-custody forms <br /> Water Levels <br /> Static water levels measured when well drilled <br /> Date of water level measurements <br /> Water levels determined prior to sampling <br /> Supporting Data: <br /> Dates of water level measurement, depths to ground water, and ground water elevations <br /> should be tabulated and included in the report. <br /> Ground Water Gradient and Flow Direction <br /> Ground water gradient and flow direction determined by the investigation should be discussed <br /> and compared to the regional gradient and flow direction. <br /> Supporting Data: <br /> A ground water contour map, drawn to scale, should be provided which shows each well, its <br /> ground water elevation, and lines of equal ground water elevation. Ground water gradient and <br /> flow direction should be shown on the.map. The calculation of the gradient should be included. <br /> V. RESULTS OF QA/QC <br /> QA/QC procedures <br /> QC sample identification <br /> Field blank analyses <br /> Comparison of duplicate sample results <br /> VI. CONCLUSIONS AND RECOMMENDATIONS <br />
