Supporting Data: <br />Dates of water level measurement, depths to ground water, and ground water <br />elevations 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 <br />be discussed 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 <br />each well, its ground water elevation, and lines of equal ground water elevation. <br />Ground water gradient and flow direction should be shown on the map. The <br />calculation of the gradient should be included. <br />RESULTS OF QA/QC <br />QA/QC procedures <br />QC sample identification <br />Field blank analyses <br />Comparison of duplicate sample results <br />CONCLUSIONS AND RECOMMENDATIONS <br />Evaluate any contamination found; <br />Compare to background levels and appropriate screening levels; <br />Identify any suspected source of contamination; <br />Recommend any further investigative needs based on data gaps; interim remedial <br />measures; public participation; <br />Page 3 of 3
