ARCADIS Mr. McKinley Lewis, Jr. <br /> April 20, 2011 <br /> Tasks 1 &2) Proposed Additional Soil Sampling in Impacted Areas and Soil <br /> Sampling In the Vicinity of the Car Battery Pallet <br /> Additional soil sampling will be conducted at the proposed locations depicted on <br /> Figure 1 (Attachment 2)for those select areas where soil analyses exceeded the <br /> regulated CHHSL, ESL, or background concentration guidelines. Soil samples <br /> will be collected and analyzed for the parameters as shown in Table 1 below. <br /> The additional sampling will be conducted to delineate"hot spots" not well <br /> defined in the PEA. Shallow soil borings B-49 through B-52 will be conducted to <br /> assess the area in the vicinity of the former car battery pallet. <br /> Table 1 -Additional Sampling Gordon Research <br /> Sample <br /> No. Depth(ft) Location Analytes EPA Method <br /> B-8 1.5 north storage containers Total Lead,Cad,As 6010B <br /> B-29 1.5 West of Trough Total Lead,Cad,As 6010B <br /> B-29 0.5 West of Trough Total Lead,Cad,As 6010B <br /> B-29 0.5 West of Trough Total Lead,Cad,As 6010B <br /> B-43 1.5 east drip line of residence Total Lead 6010B <br /> B43A 0.5 east drip line of residence Total Lead 6010B <br /> B43B 0.5 east drip line of residence Total Lead 6010B <br /> B-6A 0.5 southwest of B-6 Fuel Fingerprint&PCBs 8015B&8082 <br /> B-6B 0.5 southeast of B-6 Fuel Fingerprint&PCBs 8015B&8082 <br /> B49 0.5 lead-acid batteries Total Lead,pH 6010B <br /> B-50 1.5 lead-acid batteries Total Lead,pH 6010B <br /> B-51 0.5 lead-acid batteries Total Lead,pH 6010B <br /> B-52 1.5 lead-acid batteries Total Lead,pH 6010B <br /> pH,VOCs,SVOCs,Fuel Fingerprint, 8260,8270,8015B, <br /> Well 1 Groundwater domestic water well Total and dissolved metals 6010/7000 <br /> Page: <br /> Final PEA Work Plan Addendum-AprI t-RV009808.doc 6/11 <br />
