GEOSYNTEC CONSULTANTS <br /> Mr. Michael L. Frey <br /> 9 April 2003 <br /> Page 3 <br /> Task 1.2. Well Installation and Development <br /> Under Task 1 . 2 , GeoSyntec will install and develop the monitoring wells listed in <br /> Table 1 to confirm previous direct push investigation results in the area north of the South <br /> Gifford Road Landfill (north and northwest of the VOC source area) that suggest the <br /> presence of VOCs . The well installation and development will be conducted in accordance <br /> with FDEP Standard Operating Procedures (SOPS) that were promulgated in April 2002 . <br /> This task will involve the installation of fifteen ( 15 ) new monitoring wells, including <br /> five new well clusters of three monitoring wells each, to expand the plume monitoring <br /> network. The proposed locations for the plume monitoring wells are shown on Figure 1 . <br /> The new monitoring wells will be developed by surging and overpumping . Protective <br /> barriers (i . e. , bollards) will be installed around each new monitoring well or well cluster <br /> that may be subject to damage by heavy equipment or traffic . After installation, each new <br /> monitoring well will be surveyed by a Florida registered surveyor. <br /> The labor total includes two days ( 16 hrs) to prepare for the fieldwork, including <br /> scheduling, contract initiation and work order preparation with the subcontractors , <br /> equipment orders, and any other necessary fieldwork preparation tasks . The budget <br /> estimate for the fieldwork portion of this task assumes one person in the field for 10 hour <br /> days . The labor included in the budget estimate also assumes that the fieldwork will <br /> require approximately 12 to 13 days ( 120 to 130 hrs) for monitoring well installation and <br /> approximately three days (30 hrs) for well development . <br /> The budget estimate for this task also includes waste characterization; however, actual <br /> disposal of the waste will be handled by Indian River County as discussed below. With <br /> respect to investigation-derived waste (IDW) generated during GeoSyntec ' s fieldwork at <br /> the site, GeoSyntec will drum the drill cuttings and development water, stage the drums <br /> on-site, and mark each drum to indicate the source of the waste (e . g . , boring numbers, etc . ) <br /> contained within each drum, the generation date, and contact information. Waste <br /> characterization sampling and analysis will be performed consistent with IDW activities <br /> performed during previous contaminant assessment phases of work at the site. Two <br /> composite samples will be collected from the drums containing drill cuttings and one <br /> composite sample from the drums containing development water. These three samples <br /> XR03035/R030082 .DOC <br /> G� <br /> �, RECYCLED AND RECYCLABLE r <br />
