22 October 2009 AGE-NC Project No. 00-0697 Page 6 of 10 of boring MW6,sandy silt,silty sand,sand and clayey sand were encountered.Soil boring and well completion logs are presented in Appendix C.Cross sections A-A'and B-B'depict general Iithology beneath the site(Figures 3 and 4,respectively). 3.0. SENSITIVE RECEPTOR SURVEY A sensitive receptor survey is required as part of site characterization requirements under the California Code of Regulations(CCR)-Title 23,Division 3,Chapter 16,Section 2654.As a result of this California CCR requirement,a sensitive receptor survey was performed at the site between August and October 2005.The sensitive receptor survey consisted of identifying septic systems and municipal,domestic, irrigation or ground water monitoring wells within a 2,000 foot radius of the site. The location of the site and the immediately surrounding area are illustrated in Figure 1. Site structures are depicted in Figure 2. According to property owner Charles Jacobs, drinking water at the site is currently supplied by a domestic water well located on the adjacent property at 15010 Glasscock Road, Lodi, CA; a domestic water well is also located on-site,but is not used for drinking water. AGE was unable to ascertain the total depths and construction details of the two domestic water wells.In addition,two septic tanks are located on the east side of the property. In August 2005, an AGE representative reviewed well drillers' reports from the California Department of Water Resources-Central District for water wells located in the surrounding area. Drillers' reports for two water wells located within a 2,000-foot radius of the site were identified; a driller's report for the installation of one domestic well located at 13999 West Highway 12 and one test well located approximately 100 feet south of Highway 12 were recovered. Copies of the well driller's reports are included in Appendix F; a summary of water wells located from the review of well driller's reports is included in Table 6 and a location of wells are depicted in Figure 8. On 05 October 2005, an AGE representative performed a reconnaissance of visually observable potential sensitive receptors located within a 2,000-foot radius ofthe site.During the reconnaissance, one domestic well was located on the eastern end of the Terminous Market site. No other visible potential receptors were noted during the reconnaissance. 4.0. ASSESSMENT OF HYDROCARBON-IMPACTED SOIL Between March 2000 and February 2008,nine soil borings(B 1 through B9),five soil vapor borings (SV-1 through SV-5), and six ground water monitoring wells (MW-1 through MW-6) were installed/advanced at the site as part of an ongoing subsurface leaking UST investigation.Analytical Advoeced GmEmvimemeeal,lec.
