i <br /> i <br /> . 2.0 SCOPE OF WORK <br /> ' T v horizontal n verb I acted <br /> The objectives of the scope of work were to evaluate theand ca extent of imp <br /> soil and groundwater, establish a groundwater table monitoring capability at the site, and to <br /> determine if nearby domestic water wells had been impacted by gasoline hydrocarbons To <br /> achieve these project objectives, cone penetration testing (CPT) and discrete soil and <br /> groundwater sampling were conducted at four on-site locations, four on-site groundwater table <br /> monitoring wells were installed, and the existing water wel I survey was expanded to include door- <br /> to-door inquiries and the sampling of 11 off-site domestic water wells <br /> 21 Planning and Permitting <br /> Prior to initiating fieldwork, a site-specific health and safety plan was prepared in accordance with <br /> 29 CFR 1910 120 The health and safety plan included safety procedures, chemical hazard <br /> information, site safety officers, and preferred medical emergency locations <br /> On July 25, 2000, Ramage Environmental submitted permit applications to PHSIEHD for the <br /> drilling of the CPT borings and the installation of the four monitoring wells PHS/EHD approved <br /> the permit applications <br /> At least two working days prior to drilling, PHSIEHD and Underground Service Alert (USA)were <br /> ' notified so that regulatory and utility clearance inspections could be scheduled Underground <br /> utilities were marked by USA member utilities under Ticket#243976 <br /> 2.3 Cone Penetration Testing and Discrete Water-Bearing Zone Sampling <br /> On September 11 and 12, 2000, to evaluate the horizontal and vertical extent of impacted soil and <br /> groundwater, Gregg Drilling and Testing, Inc (Gregg), a state licensed drilling contractor (C-57 <br /> ' #656407), advanced CPT borings and collected discrete soil and groundwater samples at four on- <br /> site locations Gregg's Presentation of Cone Penetration Test Data, dated September 14, 2000, <br /> ' is included as Appendix B <br /> The four CPT locations (CPT-1, CPT-2, CPT-3, and CPT-4) are shown on Figure 2 At each <br /> location, Gregg advanced a pair of soil borings with a truck-mounted CPT rig, with a down <br /> pressure capacity of approximately 25 tons The first boring at each location was advanced with <br /> the CPT system, which records tip resistance, sleeve friction, and dynamic pore pressure at five <br /> centimeter intervals The second boring at each CPT location was dedicated for soil and discrete <br /> 8 <br />
