Box 388 <br /> Stockton, CA 95201-0388 <br /> Subject: Workplan for Former Valley Volkswagen, 647 E. Miner Street, Stockton, CA <br /> Site Code: 1187 <br /> Dear Mr. Rowe: <br /> Ground Zero Analysis, Inc. (Ground Zero) is writing to present a workplan for performing <br /> additional site investigation at the above referenced property (Figure 1). <br /> k r <br /> Bac g ound <br /> The site is located in a predominantly commercial and residential area, on the northwest corner <br /> of Miner Street and Stanislaus Street in Stockton, California. The site consists of a vacant <br /> building surrounded by asphalt parking areas. The building was previously occupied by the <br /> Morton Valley Paint Company. An Auto Service business is located adjacent to and directly <br /> north of the site. Used car dealerships are located on the three surrounding corners of the <br /> intersection of Miner Street and Stanislaus Street (Figure 2). <br /> On July 29, 1987, two underground storage tanks (USTs), one 750-gallon waste oil and one <br /> 1000-gallon waste oil, were removed from the property by Walker Hydraulics of Pleasant Hill, <br /> California. Soil samples were collected at the fill port ends of each tank. One sample was <br /> collected at 12 ft below ground surface (bgs) beneath the smaller UST. The laboratory <br /> analytical results indicated total petroleum hydrocarbon (TPH) concentrations of 370 parts per <br /> million (ppm) and total xylenes at a concentration of 44 ppm. One sample was also collected <br /> at 14 ft below ground surface from the fill port end of the larger UST. TPH was detected at <br /> a concentration of 360 ppm and total xylenes were detected at a concentration of 58 ppm. <br /> On September 1, 1987 additional soil samples were collected from the former UST pit. The <br /> samples were coIlected using a backhoe at approximately the same locations as the initial <br />
