Three (3) 6-inch diameter soil test borings will be drilled using 2. 25-inch continuous hollow stem flight augers. The borings will extend to a maximum depth of 50-75 feet will below current site grade. The samples will be containerized in glass jars for geotechnical classification and laboratory testing. After completion of drilling operation boreholes will be grouted with bentonite slurry (2 lbs of bentonite to 1 gallon of water) and the auger cuttings and all other investigation derived waste (idw) will be containerized in sealed drums per doee permit.

The current proposed phase ii esa environmental sampling and testing investigation will include the use of a geoprobe for one day to perform soil borings (b-1 to b-10) that will be extended to approximate depths of feet, measurable groundwater, or refusal, whichever occurs first. Using decontaminated drilling and sampling equipment, soil samples will be collected on a continuous basis and field screened with a photo-ionization detector (pid) for volatile organic compounds (vocs). In addition, groundwater samples will be collected from two borings, which encounter groundwater, with disposable pvc piping via disposable tubing with a peristaltic pump. Soil investigative derived waste (idw) will be placed in a drum to be left on site until receipt of the environmental laboratory analysis. Assuming laboratory results meet acceptance criteria testing requirements, a vendor will collect and dispose of the drum and contents at a permitted facility. After sample collection, each boring will be
