2.0 SCOPE OF WORK The objectives of the proposed scope of work are to assess the lateral extent of impacted groundwater, establish>a groundwater monitoring capability at the site, and survey possible sensitive receptors in the site vicinity. To achieve these objectives, three on-site groundwater monitoring wells will be installed, these wells and the on-site-domestic well will be monitored and sampled on a quarterly basis for at least one year, and a survey of possible sensitive receptors within 2,000 feet of the site will be conducted. 2.1 Planning and Permitting Prior to initiating fieldwork, a site-specific health and safety plan will be prepared according to 29 CFR 1910.120. The health and safety plan will include safety procedures for work to be performed, chemical hazard information, site safety officers, and a medical emergency location. To perform the proposed scope of work, monitoring well permits will be obtained from PHS/EHD. Since all of the drilling will be conducted on-site, neither off-site access agreements nor encroachment permits will be required. At least two working days prior to field work, Ramage Environmental will notify PHS/EHD so that any inspections can be scheduled. Underground Service Alert will also be notified to perform a utility clearance inspection. 2.2 Groundwater Monitoring Well Installations To evaluate the lateral extent of impacted groundwater and to establish a groundwater monitoring capability at the site, three on-site groundwater monitoring wells will be installed, and sampled on a quarterly basis for at least one year. The proposed wells will be installed east, west and northwest of the former USTs (Figure 2). The well to the northwest will be positioned between the former USTs and the operating on-site domestic well. 2.2.1 Monitoring Well Construction and Development The wells will be installed in 8-inch diameter soil borings drilled by a truck-mounted drill rig, equipped with hollow stem augers. The wells will consist of approximately 20 feet of two-inch diameter, Schedule 40, flush-threaded and machine-slotted (0.020-inch) PVC well screen. Since 46, groundwater is anticipated at approximately 80 feet bgs, the well screen interval will extend from approximately 70 to 90 feet bgs. Blank PVC casing will thread into the top of the well screen and extend to the surface. 8
