Mr. Witwer <br />October 9, 2008 <br />Page 2 <br />Work Plan <br />WPI proposes to install a series of ten (10) soil borings utilizing a tuck mounted push-probe <br />(geoprobe). Soil borings shall extend to groundwater or as deep as logistically possible. Soil <br />borings shall be installed in field determined locations, primarily focusing on the dry well location <br />and stockyard area. <br />A single soil sample shall be collected from each soil boring location and sent to an independent <br />laboratory for analysis of 8270 polynuclear aromatic hydrocarbons (PNAs), 8260+ volatile <br />organic compounds (VOCs), and EPA 8 metals. A minimum of two groundwater samples shall <br />also be collected from field determined soil boring locations. Groundwater samples shall also <br />be analyzed for 8270 PNAs, 8260+ VOCs, and EPA 8 metals. <br />Soils shall be continuously sampled and inspected for visual/olfactory signs of contamination as <br />well as scanned with a PID. Collected soil samples shall be placed in dedicated laboratory <br />approved containers, placed on ice, and kept at a constant temperature of approximately 4 <br />degrees Celsius. All equipment shall be decontaminated between each boring. Soil cuttings, <br />wash water, and purged groundwater shall be containerized in 55-gallon drums which will be left <br />on-site pending analytical results. This proposal does not include the costs for disposal of any <br />investigative derived wastes. <br />Upon completion of the field and laboratory work, a final report shall be prepared for your <br />review, comment and approval. The report shall include a site plan showing soil boring <br />locations, soil boring logs showing the classification of the subsurface materials encountered <br />and conditions of the soil, analytical results, and our findings and conclusions regarding the site. <br />WPI estimates the Phase II ESA field work and laboratory work can be completed in <br />approximately three to four weeks assuming all third party contractors are available in the <br />preferred time frame. Laboratory analysis can be expedited for an additional charge. <br />
