Mr. Brad Beeman - 2 - 3 March 2000 <br /> Site 19 Site Investigation <br /> NCTS, Stockton <br /> What were the results of pesticides in the other piles? Please provide a summary table with all of <br /> the sample locations and associated sampling results for each stockpile and for each constituent. <br /> 3. 2.5.2 Confirmatory Sampling. Eight composite soil samples were taken from eight stockpiles. <br /> Two ounces of soil were scooped from four locations in a pile, which equals 8 ounces of soil from <br /> the stockpiles. The stockpiles are very large and contain hundreds of cubic yards of soil. We do <br /> not consider 8 ounces of soil, composited from these large piles, to be representative. Please <br /> provide a representative sampling plan which describes soil sampling procedures based on the <br /> calculated cubic yardage of each stockpile. A grid patten should be utilized for each pile. Each <br /> square in the grid should be sampled. No more than 4 samples should be composited in order to <br /> ensure that hot spots can be detected. <br /> Please provide tabulated results of the initial sampling of CAM 17 metals showing elevated levels <br /> of beryllium, cadmium, cobalt, copper, lead, molybdenum, nickel, vanadium, and zinc. <br /> The Board was not provided with a Draft Site Investigation Work Plan describing the proposed site <br /> investigation prior to these activities. In the future, we recommend the Navy provide work plans for <br /> State agency review prior to proceeding with environmentally related activities. <br /> If you have any questions please contact me at (916) 255-3078 or schwabk(-rb5s.swrcb.ca.gov. <br /> Z(� d- <br /> Kim A.
