1 0 INTRODUCTION/HISTORY <br /> J.B Terminal Company/Bli.ncoe Trucking --ompany operates a <br /> trucking facility located at 6700 Grantl-ne Road, Tracy, <br /> California ( Figure 1 ) . In September, 1987, two 550 gallon <br /> underground fuel storage tanks were removed from the <br /> facility. The tanks were used to store leaded and unleaded <br /> gasoline. Figure 2 depicts the tank locations relative to <br /> other facility features. <br /> This report is being submitted in response to a request by <br /> the San Joaquin County Public Health Services, Environmental <br /> Health Division to address residual soil and potential <br /> groundwater contamination at this site. Analysis of samples <br /> collected from the tank excavation at the time of tank <br /> removal indicated lour concentrations of petroleum related <br /> constituents in soil and groundwater. Laboratory results <br /> for samples are summarized in Tables 1 and 2 . Laboratory <br /> data sheets are included in Appendix I . <br /> Field and laboratory data indicated the presence of low <br /> concentrations of toluene, xylenes, and total petroleum <br /> hydrocarbons as gasoline in soils and groundwater within the <br /> tank excavation. Ethylene dibromide, organic. lead, nor <br /> benzene were not detected in any samples above method <br /> detection limits. Based on the constituents and the ` evels <br /> detected, the excavation was backfilled. <br /> i <br /> 2.0 TECHNICAL DATA <br /> 2 . 1 Name and address of site, tank owner, and contact person: <br /> Site and Tank Owner; Bla.ncoe Truc%ing Company/ <br /> J.B.
