A <br />complete analytical <br />report for the sampling conduc-'Ced by Canonie <br />Environmcntal was previou--ly subn <br />�Itted to the San Joaquin County <br />PFI_C/RHr). Analytical results for the soil <br />samples taken from <br />beneath thL-� regular gas dispenser indicated elc <br />lead, suggesting �Ivatod levels <br />e <br />of <br />that the dispenser may have leaked. Because of <br />this apparent Ita% and the <br />loose <br />unleaded fitting found near- the 2000 gallon <br />tank, the <br />PHS/ETID directed Seibold Corporationto re - <br />excavate and Sample at a greater depth beneath <br />the regular gas <br />dispenser and in the area beneath the former <br />2000 gallon unleaded <br />gas tank location. Re -excavation was done by Seibold <br />on August 5 and 6, 1990. Corporation <br />3.0 soil sampling <br />• <br />After the completion of the additional excavation (completed August <br />1990) <br />t6, <br />soil samples were Collected from the excavation pit <br />beneath the former unleaded <br />gas tan's and beneath the regular gas <br />dispenser. The samples were collected <br />on August 7, 1?9n by WESTON. <br />A total -of six Sall Samples were collected, five frim the 'unleaded <br />tank <br />gas re -excavation .pit. and a single sample t;:Qm beneath the <br />regular gas dispenser (Figure 3). <br />All the samples were analyzed <br />for total petroleum hydrocarbons (TPH-G) benzene, <br />, toluene, xylene, <br />and ethylbenzene (BTX&E). The sample collected from beneath the <br />regular gas dispenser was <br />also analyzed <br />(EDB). All for ethylene dibroMid, <br />sampling Protocol <br />was approved by the on-site Count, <br />representative Ms. Darlene Reuss. A <br />detailed description of <br />sampling methodology is presented in the Field Report, Appendix <br />All <br />A. <br />s3mPling was performed under the direction Of a Registered <br />California Geologist. <br />3,1 Analytical Result,_ <br />Table 2 presents the results <br />complete Of the WESTON -soil analyses.
