Mr. Himanshu H . Mehta, P . E . 30 September 2011 Page 3 For the purpose of budgeting , the scope of work has been divided into the following four main phases : • Phase 1 — Project Management ; • Phase 2 — Injection and Monitoring Well Installation ; 0 Phase 3 — Injection Activities ; and • Phase 4 — UIC and Performance Monitoring and Reporting . The remainder of this section presents a general description of the activities to be performed in each phase . Phase 1 — Project Management Under this task, Geosyntec will perform project planning and management responsibilities , such as correspondence with IRC SWDD and FDEP, invoice review, project coordination , and project administration . Phase 2 — Iniection and Monitoring Well Installations This task includes the activities associated with providing oversight to drilling subcontractors , as required , to install the proposed former source area injection wells to augment the existing well network and one additional monitoring well to assess CVOC concentrations upgradient of biobarrier transect 1 . A total of 12 injection well clusters (two wells in each cluster for 24 total wells) will be installed beneath the former source area and in the vicinity of monitoring well GR-MW3013 . The injection well clusters will be installed with a direct-push technology (DPT) drill rig and constructed similar to the existing former source area injection wells : 3/4- inch PVC with a stick- up completion approximately 2 ft above land surface . The 0 . 010 - inch slotted screens will be 5 ft in length and extend from approximately 25 to 30 ft BLS (even numbered wells) and 33 to 38 ft BLS (odd numbered wells) . One monitoring well , GR-MW3613, will be installed with a DPT drill rig approximately 20 feet west of biobarrier transect 1 and screened from 40 to 50 ft BLS . The monitoring well will be constructed of l inch diameter schedule 40 PVC , with pre-packed 20/30 sand surrounding the 0 . 010 - inch slotted screen . Two feet of 30/65 fine sand seal will be added above the filter pack and the remaining annular space will be grouted to land surface . The monitoring well will be completed with an expandable well cap and an 8 - inch diameter steel manhole, set in a 3400t by 346ot by 4 - inch thick concrete pad .
