2.0 SCOPE OF WORK <br /> 1 The objectives of this investigation were to further define the extent of impacted soil and to <br /> determine if groundwater had been impacted beneath the site To achieve these objectives, soil <br /> and groundwater-grab samples were collected for laboratory analysis from three on-site soil <br /> borings <br />' 21 Project Planning <br /> The project planning task included the preparation of a health and safety plan, acquisition of <br /> required permits, advance notifications and a routine underground utility survey <br /> Prior to initiating fieldwork, a site-specific health and safety plan was prepared according to 29 <br /> CFR 1910 120 The health and safety plan included safety procedures for work to be <br /> performed, chemical hazard information, site safety officers, and a medical emergency location <br /> To perform the proposed scope of work a drilling permit was obtained p g p twined from PHS/EHD Since all <br /> of the drilling was conducted on the subject site, neither private property access agreements nor <br /> encroachment permits were required A copy of the permit is included in Appendix A <br /> At least two working days prior to field work, PHSIEHD was notified so that any regulatory <br /> inspections could be scheduled Underground Service Alert (USA) was also notified to mark any <br />' underground utilities (USA Ticket#24652) <br /> 22 Soil and Groundwater-Grab Sampling and Analysis <br />' On February 3, 2001, soil androundwater- rab samples were collected from <br /> 9 9 p three on-site <br />' locations using a Geoprobe® Direct-Push Technology rig (Geoprobe), operated by Fisch <br /> Environmental (C-57 License#683865) To evaluate the concentration and extent of any <br /> impacted soil and/or groundwater associated with the former UST system, one soil boring was <br />' drilled at each end of the former UST, and one soil boring was located adjacent to the former <br /> underground piping run near P1 (Figure 2) These locations previously exhibited the highest <br />' concentrations of gasoline hydrocarbons in soil <br /> All three soil borings were advanced to total depths of 20 feet bgs Groundwater was <br /> encountered in all three borings at depths ranging from 14 2 to 15 0 feet bgs <br /> 6 <br />
