Water Levels <br /> Static water levels measured when well drilled <br /> Date(s) of water level measurements <br /> Water levels determined prior to sampling <br /> Supporting Data: <br /> Dates of water 7e ve 7 measurement, depths to ground water, a n d ground <br /> water a 7e va t ions shou Id be tabula ted and inc luded in the report <br /> Ground Water Gradient and Flow Direction <br /> Ground water gradient and flow direction determined by the investigation <br /> should be discussed and compared to the regional gradient and flow <br /> direction <br /> Supporting Data: <br /> A ground water contour map, drawn to scale, should be provided which <br /> shows each we17, its ground water elevation, and lines of equal ground <br /> water elevation. Ground water gradient and flow direction should be <br /> shown on the map. The calculation of the gradient should be included. <br /> V. RESULTS OF QA/QC <br /> Field blank analyses <br /> Comparison of duplicate sample results <br /> VI. CONCLUSIONS AND RECOMMENDATIONS <br /> Note any contamination found <br /> Identify any suspected source of contamination, if possible <br /> Recommend any further investigative needs <br /> The topics listed above are only the minimum which need to be included in <br /> preliminary site assessment reports for the Regional Board's Well Investigation <br /> Program. All other pertinent information specific to each individual <br /> investigation also should be included. <br />
