qionudakis Firewood, Inc. <br /> Page 8 of 9 <br /> Ms. Foley and Mr. Naidu of EHD requested that soil from a specific area, which Mr. Naidu <br /> indentified as having a "chemical odor", be isolated from the main stockpile. The stockpile was <br /> placed on visqueen, covered and secured with visqueen. On March 1, 2010, Ground Zero requested <br /> permission to remove the small stockpile. The stockpile remains on-site pending disposal <br /> directives from EHD. Soil from the small stockpile was placed into two 6-inch brass sleeves, <br /> sealed with Teflon® tape, capped, uniquely labeled, and stored in an ice chest refrigerated to a <br /> temperature of approximately 4°C pending shipment under chain of custody protocol to Argon. <br /> As requested by EHD, the samples were composited by Argon and analyzed for the following: <br /> • TEPHd, TEPHk, and TEPHmo by EPA method 8015M <br /> • VOCs by EPA method 8260B <br /> • Semi-Volatile Organics (Full Scan)by EPA method 8070C <br /> • CAM 17 metals by EPA method 6020/6020A <br /> Each individual sample was also analyzed for TEPHd by EPA method 8015M. Sample locations <br /> are shown in Figure 4. Field Notes are included as Attachment B-3. <br /> 4.6 Stockpile Sample Analytical Results <br /> Results from the metals analysis were below ESLs. All other analyzed constituents were not <br /> reportable above detection reporting limits. <br /> Analytical results from the Stockpile Sample Analysis are summarized in Table 8 and Table 9. The <br /> Laboratory Analytical Report is included as Attachment C-5. <br /> 5.0 FINDINGS AND DISCUSSION <br /> • The storm drain tests reveal that residue from chemicals of concern are not present in the <br /> storm drain system. <br /> • Results of the EHD and Ground Zero investigations indicate that the contamination was <br /> petroleum hydrocarbon in nature. <br /> • Results of the EHD and Ground Zero investigations indicate that the contamination was <br /> concentrated within a limited area. <br /> • Excavation activities showed that the impacted soil was limited to a small area defined by <br /> samples B3, GP-1, GP-2, GP-3, GP-4, and CFI-23. <br /> • Analytical data collected from the extents of the excavation and the excavated soil indicate <br /> that the impacted soil has been removed from the Site. <br /> G:IGROUNDZEILIONUDAKISIReportslSite Assessment and Excavation Report.doc March 2010 <br />
