—� 1 <br /> 26 May 1998 <br /> AGE-NC Project No. 97-0326 <br /> Page 2 of 5 <br /> measured in each UST prior to removal. All USTs were examined for holes and condition upon <br /> removal. The removed USTs were transported by West Coast Equipment to Turlock for recycling <br /> as scrap metal. A receipt for acceptance of the USTs is included in Appendix A. <br /> During removal of the piping and dispensers, additional abandoned piping was discovered at the site <br /> and was removed. The locations of all discovered product piping runs are illustrated on Figure 2. <br /> 3.2. SOIL SAMPLE COLLECTION <br /> Immediately following removal of the USTs, soil samples were collected from approximately two <br /> feet below the former UST inverts. On 20 February 1998, one soil sample was collected from the <br /> location of each dispenser and an additional sample collected from between the dispensers (P1 <br /> r•- through P5). Sample locations were specified by the PHS-EHD. Three sample were collected on 20 <br /> February 1998 from the soil stockpiled on-site. Sample iocations are illustrated on Figure 2. <br /> The soil samples were collected in pre-cleaned 2-inch by 3-inch brass sleeves. Samples from <br /> beneath the USTs were collected from the backhoe/excavator bucket. The ends of each brass sleeve <br /> were covered with Teflon sheets,capped and sealed with tape. The samples were then labeled, stored <br /> on ice and transported under chain-of-custody to Alpha Analytical Laboratories, in_. (AAL), a state- <br /> certified laboratory. <br /> 3.3. SAMPLE ANALYSIS <br /> A total of eight UST samples, five piping/dispenser samples and three stockpile samples were <br /> collected and analyzed for: <br /> • Total petroleum hydrocarbons quantified as gasoline (TPH-g) in accordance with EPA <br /> Method 5030 <br /> • Volatile aromatic compounds (benzene, toluene, ethylbenzene and xylenes; BTE&X) with <br /> methyl tertiary-butyl ether (MTBE) in accordance with EPA Method 8020 <br /> • Oxygenated compounds in accordance with EPA Method 8260. <br /> Three sub-UST soil samples were also analyzed for total lead in accordance with method 6010. <br /> Advanced GeoEnvironmental.Inc. <br />
