N 20 August 2009 AGE-NC Project No . 064457 Page 2 of 7 Therefore, AGE proposes to install water table monitoring wells to 40 feet bsg, approximately 50 feet southwest of well MW- 1 to monitoring the up-gradient extent of the plume, and approximately 25 feet southeast of monitoring well MW-3, to monitor the plume's off-site encroachment. AGE proposes to install ground water monitoring wells near well MW-2 and CPT-2 to approximate depths of 80 feet bsg (approximately 10 feet northeast of MW-2) and 105 feet bsg (approximately 10 feet south of MW-2). AGE proposes to install two additional 80 feet bsg wells approximately 25 feet southeast of well MW-3 , and off-site, approximately 125 feet east of well MW4, which will allow for a ground water flow evaluation at the deeper depth (80 feet bsg). Boring locations are shown on Figure 2. Historical analytical results of quarterly ground water samples are summarized in Table 1 ; analytical results of grab ground water samples are summarized in Table 2. The proposed scope of work will include the following tasks : • Permitting and pre-field work activities; • Boring advancements, monitoring well installation and sampling; and • Report preparation. Each of these tasks is described in greater detail below. 2. 1 . PRE-FIELD WORK ACTIVITIES Applicable site assessment permits will be obtained from the EHD and an encroachment permit will be obtained from the City of Stockton for the proposed off-site well. In addition, a health and safety plan will be updated in accordance with Occupational Safety and Health Guidance Manual for Hazardous Waste Site Activities (National Institute for Occupational Safety and Health Administration, U.S . Coast Guard and U. S . Environmental Protection Agency, 1985). Prior to mobilization, each proposed boring location will be clearly marked and an utility clearance obtained through Underground Service Alert. 2 .2, MONITORING WELL INSTALLATION AGE proposes to install two water table (approximately 40 feet bsg) wells, three wells to a depth of approximately 80 feet bsg, and one deep screened monitoring well to a depth of approximately 105 feet bsg. The location of the proposed monitoring wells are illustrated on Figure 2 . Advanced GeoEnviranmental, Inc.
