Mr. Himanshu Mehta <br />19 May 2022 <br />Page 2 <br />Phase 2 — Meetings/Regulatory Interaction <br />Under this phase, Geosyntec provided ongoing support to IRC SWDD related to interaction and <br />negotiation with FDEP. <br />Phase 3 — Annual Pollution Remediation Liabilities Evaluation <br />Under this phase, Geosyntec prepared the annual environmental liability evaluation in response to <br />Governmental Accounting Standards Board Statement No. 49 (GASB No. 49), Accounting and <br />Financial Reporting for Pollution Remediation Obligations, which requires the inclusion and <br />calculation of pollution remediation obligations. The report included the evaluation of two sites, <br />Former South Gifford Road Closed Landfill (4701 41s' Street) and Former Premier Citrus Property <br />(37582 d Avenue) and was submitted to IRC on 5 November 2021. <br />Phase 4 — Semi -Annual Sampling Activities <br />Under this phase, Geosyntec conducted field preparation and groundwater sampling activities for <br />two semi-annual groundwater monitoring events in June and December 2021. Throughout these <br />three sampling events, a total of 50 groundwater samples were collected under this work <br />authorization. Geosyntec provided oversite for a drilling contractor to repair the aboveground <br />portion of the polyvinyl chloride (PVC) well casing at one monitoring well, and also for a Florida - <br />licensed surveyor to survey the repaired monitoring well. <br />Phase 5 — Data Evaluation/Reporting <br />Under this phase, Geosyntec prepared the semi-annual reports for the June and December 2021 <br />events. As part of the report preparation, Geosyntec completed database management, data <br />evaluation, trend evaluation, table preparation, and GIS figure preparation. Each report was <br />submitted to IRC SWDD for review and comment prior to submittal to FDEP. The 2021 Annual <br />Groundwater Monitoring Report was approved by FDEP on 4 March 2022. Following submittal of <br />the 2021 Annual GMR, further data analysis was performed to evaluate concentration trends and the <br />potential need for further bioremediation because the previous remedial injection was performed <br />five years ago (April 2017). <br />BUDGET <br />The approved budget for Work Order No. 12 was $84,339. The total invoiced amount, including the <br />final invoice, is $80,707.93. Therefore, Geosyntec completed this project below the approved <br />budget, resulting in a cost savings to IRC of $3,631.07. <br />PR22023_P-iect Completion WO No 12_FR0766S.doc <br />engineers I scientists I innovators <br />145 <br />
