Tracy Boulevard, Tracy, CA <br /> Hi Angelica, <br /> The attached technical report is a response to your letter dated April 03, <br /> 2014. <br /> After a thorough evaluation of site conditions, it is my professional opinion <br /> that no further site assessment is necessary as the contamination is only <br /> diesel; which is not toxic or carcinogenic. <br /> In addition, it appears that there are two separate aquifers; a shallow one <br /> at a depth of 14 to 15 feet bgs and a deeper aquifer which is used for <br /> water supply. <br /> It also appears that these two aquifer are not connected, making <br /> contamination of the deeper groundwater by the diesel dispenser leak very <br /> unlikely. <br /> Regardless, it is even more unlikely that the discharge from this diesel <br /> dispenser would enter a water supply well. <br /> It looks like the water supply wells in the area are too far away from the <br /> site for a diesel plume of this size to reach them. In addition, it appears <br /> that most, if not all, water supply wells in the area have 50 foot seals. <br /> In any case, I would like to know if you will reconsider your previous denial <br /> of closure. <br /> Kindest regards, <br /> Frank Goldman, CHG <br /> 707 906 9048 cell <br /> 3 <br />
