Preliminary Report <br /> A. Teichert & Son, Inc. <br /> Tracy Aggreqate Plant <br /> Tracy, California <br /> This report contains the prelimincry exploration and <br /> investigation data and recommendations for removal of fuel- <br /> contaminated soil at A. Teichert & Son, Aggregate Plant, Tracy, <br /> California. <br /> SUMMARY <br /> March 12, 1987, A. Teichert & Son removed three small <br /> gasoline tanks located souti. of the maintenance building as shown <br /> on the attached map. <br /> Soils tests indicate gasoline contamination at the bottom of <br /> the tank hole as presented in Table 1. Table II presents results <br /> of soils tests taken during drilling in July, 1987. <br /> Analytical results presented in Table I and II indicate high <br /> levels of contamination at the b-ttom of tank hole. Field tests <br /> on May 8, 1987, indicate the contamination is greatly reduced at <br /> 17 ± feet deep in the tank hole. <br /> Backhoe pits No. BP-2, BP-3, and B-4, to 17 feet deep indi- <br /> cate no lateral contamination. Exploration drilling BH-1 <br /> (MW-1) , BH-2, and BH-3 also indicate very. little lateral <br /> ` movement of contaminates and very little contamination below <br /> �. approximately 20 feet deep and no ground water contamination. <br /> To expedite; the cleanup by the most economical method, it is <br /> recommended that the contamination be excavated and aerated on <br /> site. <br /> �r <br /> Ran I 1 !111 11 1 le 111 <br /> i <br /> 1 <br /> F� <br />
