2.0 SCOPE OF WORK <br /> iThe objectives of the site investigation were to evaluate the vertical extent of impacted soil beneath <br /> the north end of the middle former UST and to determine if groundwater had been impacted by <br /> gasoline hydrocarbons To achieve these project objectives, one soil boring was drilled for soil and <br /> groundwater-grab sampling and analysis, and groundwater from the on-site water well was <br /> tsampled and laboratory analyzed <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 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 from PHSIEHD Since the <br /> soil boring was located on-site, neither encroachment permits nor private property access <br /> agreements were required <br /> On November 9, 1999, Underground Service Alert was notified to perform a utility clearance <br /> inspection (Ticket#648211) At least two working days prior to field work, PHSIEHD was also <br /> notified so that an inspection could be scheduled <br /> 2.2 Soil and Groundwater-Grab Sampling and Analysis <br />' To evaluate the vertical extent of impacted soil beneath the north end of the middle former UST and <br /> to determine if groundwater at this location had been impacted by gasoline hydrocarbons, one soil <br /> boring was drilled for soil and groundwater-grab sampling and laboratory analysis The location of <br /> the soil boring is shown on Figure 3 <br /> The single soil boring was drilled to a total depth of 83 feet bgs The boring was advanced with a <br /> truck-mounted drill rig using 8-inch outside-diameter hollow stem augers Soil samples were <br /> collected at five-foot intervals using a modified California split spoon sampler, lined with two-inch <br /> diameter brass sleeves A field geologist logged all soil samples for hydrogeologic and lithologic <br /> characteristics according to the Unified Soil Classification System and screened each sample for <br /> any hydrocarbon vapors using an organic vapor monitor, equipped with a photoionization detector <br /> (PID) <br /> 7 <br /> 1 <br />
