(ATC) has prepared this report, on behalf of Mr. Ernest Foppiano, to <br /> summarize results of subsurface investigation activities performed in association with the former <br /> Stockton City Taxi Cab Company located at 2085 East Fremont Street in Stockton, California <br /> i- (Figure 1 ). The purpose of the subsurface investigation was to evaluate the horizontal and <br /> vertical extent of petroleum hydrocarbon impacted groundwater southeast of the subject site. <br /> ri This work was conducted at the request of the San Joaquin County Environmental Health <br /> Department (SJCEHD). <br /> 11 Site Location <br /> - - <br /> - . The site is located at the northeastern comer of the intersection of East Fremont Street and Laurel <br /> Street in Stockton, California, as shown on Figures 1 and 2. The property is located in a mixed <br /> residential and commercial area. The site is currently occupied by a retail automobile business. <br /> 1_2 Background Information <br /> In 1998, two 10,000-gallon gasoline underground storage tanks (USTs) and associated product <br /> piping were removed from the site by Advanced GeoEnvironmental. Soil samples were collected <br /> from the tank pit and under product piping and analyzed for petroleum hydrocarbons. Analytical <br /> testing indicated the samples collected from the tank pit contained detectable concentrations of <br /> petroleum hydrocarbon constituents. <br /> In February 2000, WHF, Inc. (WHF) advanced two soil borings, BI and 132, to depths of <br /> approximately 81 . 5 and 31 . 5 feet below ground surface (bgs), respectively. Soil and groundwater <br /> samples were collected from the borings and submitted for laboratory analyses. These soil and <br /> groundwater samples contained detectable concentrations of petroleum hydrocarbon constituents. <br /> i <br /> In July 2003 , WHF advanced six soil borings, four of which were completed as monitoring wells <br /> MWl through MW4. Soil samples collected from these borings contained detectable <br /> concentrations of petroleum hydrocarbon constituents. Petroleum hydrocarbons were detected in <br /> groundwater samples collected from MWl through MW4. <br /> S:\Enviromental\28349Veports\Inv rpt 2008.doc 1 ATC Associates Inc. <br />
