of the well . The tremie pipe will remain in place in the neat <br /> cement grout until placement is complete . The cover of the <br /> monitoring well will be clearly marked "monitoring well" . <br /> The total boring depth, as well as the depths of the sand pack <br /> and bentonite seal, will be sounded w th a weighted tape during <br /> installation of the well . <br /> Drill cuttings generated during field activities will be placed <br /> on a polyethylene-lined pad and also covered with polyethylene <br /> sheets at the Site. <br /> After the well is completed, the elevation of the top of casing <br /> will be surveyed to the nearest 0 . 01 foot, and tied vertically to <br /> mean sea level and horizontally to a permanent benchmark located <br /> in the vicinity of the Site . <br /> It is anticipated that five soil samples will be collected from <br /> each monitoring well boring (or the equivalent of a total of <br /> fifteen soil samples) . A minimum of three soil samples <br /> (collected from depths of approximately ten and twenty feet, and <br /> groundwater table depth) from each boring will be analyzed. <br /> These samples will be analyzed on a normal two-week turnaround <br /> basis . <br /> l <br /> The monitoring wells will be developed and sampled following <br /> procedures presented in Appendix A. The monitoring wells will <br /> developed a minimum of 72 hours following well installation. <br /> Groundwater sampling activities will be performed a minimum of 72 <br /> hours following development of the wells . <br /> 4.3 Laboratory Analyses <br /> The groundwater and selected soil samples will be sent to a <br /> state--certified laboratory and analyz d for: <br /> • TPHd using EPA Method 3550/ CFID; <br /> • TPHg using EPA Method 5030/ CFID; and <br /> • BTEX, and MTBE using EPA ME hod 8020/8250 . <br /> 111 These samples will be analyzed on a normal one--week turnaround <br /> basis . <br /> 5 <br />
