f <br /> 12 December 1995 <br /> AGE-NC Project No. 95-0140 <br /> Page 2 of 5 <br /> Upon completion of the waste removal, a Cleanup Report("McDonald Island Cleanup Report" dated <br /> 22 August 1994) was prepared by FEA. The Cleanup Report provides a detailed inventory and <br /> locations for debris and garbage removed from the site. A copy of the Cleanup Report was provided <br /> to the PHS-EHD and the San Joaquin County District Attorneys office. <br /> The Cleanup Report summarizes the collection of soil samples at the site during the cleanup. Samples <br /> suspected of containing regulated compounds, were analyzed for volatile and semi-volatile organics, <br /> polychlorinated biphenyls(PCBs), organochlorine pesticides, total recoverable hydrocarbons (TRPH), <br /> total petroleum hydrocarbons (TPH), metals, volatile aromatics and RCI (reactivity, corrosivity and <br /> ignitability). Copies of the laboratory reports and chains-of-custody were included in the Cleanup <br /> Report. <br /> Suspected contaminated materials were excavated and disposed of at licensed facilities. After <br /> contaminated materials were removed, two water samples were collected from the excavation and <br /> analyzed for total petroleum hydrocarbons (TPH-all). No hydrocarbons were detected in the <br /> composite sample. <br /> 2.4. REGULATORY MEETINGS <br /> On 23 August 1994, representatives of ZMI, FEA and Geological Audit Services, former <br /> environmental consultants, met with Mr. Wilson and Mr. Irey to discuss final closure sampling for <br /> the site. Though no sampling guidelines were provided by representatives of the PHS-EHD or <br /> SJCDA, the meeting concluded with the understanding that some confirming soil and groundwater <br /> samples should be collected. <br /> On 6 September 1995, a meeting to discuss the proposed scope of work at the site was attended by <br /> representatives of the PHS-EHD, ZMI, and AGE. During the meeting, it was agreed upon that five <br /> soil probings would be advanced approximately 10 to 15 feet using direct push technology (DPT). <br /> Discrete soil samples would be collected at five foot intervals and one"grab" ground water sample <br /> were to be collected from each penetration. <br /> 3.0. PROCEDURES <br /> 3.1. PROBING AND SOIL SAMPLE COLLECTION <br /> On 25 and 26 September 1995, five DPT penetrations (BI - B5) were advanced to depths of <br /> approximately 12 feet below surface grade (bsg) at the above referenced site. Advancement of <br /> probings was accomplished utilizing a van-mounted Geoprobe 5400 equipped with 1.125-inch <br /> diameter probe rods to depths of approximately 12 feet bsg. The probing locations are depicted on <br />
