r 07 October 2004 AGE-NC Project No. 01-0887 Page 3 of 6 from probe boring P-2, located near the former UST piping (Table 2). On 27 May 2003, four ground water monitoring wells (MW-1 through MW-4) were installed. The wells were developed on 09 June 2003 and surveyed on 24 rune 2003. Well MW-3 was established approximately 20 feet northeast of the former UST location (Figure 2). Wells MW-1, MW-2, and MW-4 were established around the western portion of the former fuel piping, where the highest concentrations of petroleum hydrocarbons were detected in the soil. Target analytes were detected in soil samples collected from borings MW-1 through MW-3, with the highest concentrations of dissolved hydrocarbons occurring in monitoring well MW-1, located adjacent to the former fuel pipeline. The ground water monitoring network has been monitored since June 2003. Over that time span,the highest concentrations of dissolved hydrocarbons have consistently been detected in well MW-1, located adjacent to the former fuel pipeline. Analytical results of ground water samples are summarized in Table 2. The vertical and lateral extents of impacted soil and ground water have not been fully defined. 3.0. SCOPE OF WORK The proposed scope of work is to assess the vertical and lateral extent of hydrocarbon-impacted soil and ground water on the site. The assessment includes the following tasks: • Permitting and pre-field work activities; • CPT drilling and sample collection; • Laboratory analysis of soil and grab ground water samples; and • Preparation of a report of findings. 3.1. PERMITTING AND PRE-FIELD WORK ACTIVITIES Applicable site assessment permits will be obtained from the EHD. Prior to mobilization, the proposed boring locations will be clearly marked and a utility clearance obtained through Underground Service Alert. The EHD will be notified 48 hours prior to conducting investigation activities. Advanced GeOEnvironmental,Inc.
