Mr. Himanshu H. Mehta, P.E. <br />30 April 2018 <br />Page 2 <br />Geosyntec <br />consultants <br />CVOC plume centerline concentrations over time; and (iii) assess the impact of biological and <br />physical natural attenuation processes on CVOC plume degradation. <br />In consideration of the ongoing natural attenuation processes occurring at the site, the enhancement <br />of these biological processes via the injection of an electron donor was proposed and agreed to in <br />concept by the FDEP in correspondence dated 2 August 2006. In response to FDEP's request and <br />supported by groundwater monitoring results, Geosyntec conducted an injection event in 2017 <br />[Remedial Action Plan Modification Addendum No. 3 (RAPM3)] to remediate recalcitrant CVOC <br />groundwater impacts in the former source area. Semi-annual performance monitoring associated <br />with bioremediation implementation is ongoing at monitoring well GR-MW37B and conducted <br />concurrently groundwater monitoring of the plume monitoring well network. <br />PROPOSED SCOPE OF WORK <br />The proposed scope of work consists of semi-annual groundwater monitoring and reporting and <br />related activities to be performed on behalf of IRC SWDD at the Former South Gifford Road <br />Landfill. For the purpose of budgeting, the scope of work has been divided into the following <br />tasks: <br />• Task 1 — Project Management; <br />• Task 2 — Meetings/Regulatory Interaction; <br />• Task 3 — Annual Pollution Remediation Liabilities Evaluation; <br />• Task 4 — Semi -Annual Sampling Activities; <br />• Task 5 — Monitoring Well Maintenance; <br />• Task 6 — Brush Clearing Activities; and <br />0 Task 7 — Data Evaluation and Semi -Annual Reporting. <br />The remainder of this section presents a general description of the activities to be performed in <br />each task. <br />Task 1 — Proiect Manaeement: Under this task, Geosyntec will perform project planning and <br />management responsibilities, such as correspondence with IRC SWDD and FDEP, invoice review, <br />project coordination, and project administration. The budget includes ten hours per <br />sampling/reporting event for the project manager, two hours for the principal -in -charge, and two <br />hours for the administrative assistant. <br />FR0766\XR 18011 <br />engiI7eers I scientists I innovators <br />
