09 April 2002 <br /> AGE-NC Project No. 97-0301 <br /> Page 5 of 14 <br /> bsg; two SVE wells will be screened 10 to 40 feet bsg (VW- 1 and VW-2), one 2-inch diameter air <br /> sparge well (AW- 1 ) will be screened between 40 and 45 feet bsg, one 2-inch diameter ozone sparge <br /> well (OSW-1) will screened between 40 and 42 feet bsg. Additionally, AGE proposes to advance <br /> four multi-level ground water monitoring wells (MW-8, MW-9, MW- 10 and MW- 11) to depths of <br /> approximately 125 feet bsg to characterize and delineate the vertical extent of petroleum <br /> hydrocarbon-impacted ground water at the site. <br /> Following installation of ground water extraction well EW- 1 , a 24-hour aquifer pumping test will <br /> be performed at the site to predict a general ground water radius of influence and capture zone during <br /> ground water extraction. <br /> i <br /> Following installation of SVE wells VW- 1 and VW-2, an 8-hour SVE pilot test will be performed <br /> at the site to predict a general radius of influence during SVE activities. <br /> Following installation of air sparge well AW- 1 , a 48-hour IAS pilot test will be performed at the site <br /> ! � to predict a general radius of influence during air sparge activities. <br /> At the conclusion of the 48-hour 1AS pilot test, an 8-hour SVEJAS pilot test will be performed at <br /> the site to monitor for SVE variation during 1AS activities.. <br /> Following installation of ozone sparge well OSW- 1 , a 4-week ozone sparging pilot test will be <br /> l performed at the site to predict a general radius of influence during ozone sparging activities and to <br /> monitor changes in ground water quality. <br /> The scope of work will consist of the following tasks: <br /> • Permitting, planning and pre-field work activities; <br /> , I <br /> • Drilling and well installation; <br /> • Performance of a 24-hour ground water aquifer pumping test; <br /> • Per-formance o€an- 8-hour-SVE-pilot test; <br /> • Performance of a 48-hour air sparge pilot test; <br /> • Performance of an 8-hour SVE/lAS pilot test; <br /> • Performance of an 4-week ozonesparging ilot test; <br /> p <br /> • Preparation of a Corrective Action Plan, including a Problem Assessment Report (PAR), <br /> j Feasiblity Studies Report and Final Remediation Plan (FRP) . <br /> i <br /> -!
