2.0 SCOPE OF WORK The objectives of the proposed scope of work are to further define the impact to groundwater below the water table, and to establish a groundwater monitoring capability downgradient of the plume of impacted groundwater. To achieve these objectives, cone penetration test (CPT) •- borings will be advanced for discrete groundwater sampling at six on-site locations, a two-well monitoring well cluster will be installed downgradient of the existing monitoring well network, and quarterly groundwater monitoring, sampling and analysis will continue. 2.1 Planning and Permitting Prior to initiating fieldwork, a site-specific health and safety plan addendum 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. For the proposed work, drilling permits will be obtained from PHSIEHD. Since all of the LW proposed drilling will be on-site, neither encroachment permits nor private property access agreements will be required. At least two working days prior to any field activity, Ramage Environmental will notify PHSIEHD so that any inspections can be scheduled. Underground Service Alert will also be notified to perform a utility clearance inspection. 2.2 Cone Penetration Testing To further determine the soil stratigraphy, and to evaluate the vertical and lateral extent of impacted groundwater beneath the groundwater table, six CPT borings will be drilled for the collection of discrete deeper groundwater samples. One CPT boring will be located at CPT-1 and advanced deeper than the 125-foot total depth of CPT-1 to identify and discretely sample any groundwater-bearing intervals below 125 feet. The five other proposed CPT locations will be approximately 100 feet east, 60 feet south, 210 feet west, 140 feet northwest, and 150 feet north (downgradient) of CPT-1 (Figure 2). The proposed CPT borings will be extended to a maximum depth of 200 feet, but the actual depth of the borings will be based on field observations and the performance of the CPT rig. 6
