Mr. Himanshu H. Mehta, P.E. 20 December 2024 Page 8 sealed by a Florida registered professional engineer. These reports will be submitted to the SWDD for review prior to submittal to the FDEP. The reports (in Adobe format) and analytical data Electronic Data Deliverable (EDD) will be submitted electronically to the FDEP using the ADaPT software in accordance with Section V.E of the WQMP. According to the WQMP, monitoring test results shall be submitted to the FDEP within 60 days from completion of laboratory analyses. Phase 3 Quarterly Assessment Monitoring and Reporting (Both C&D Debris Disposal Facility and Class I Landfill) Geosyntec will perform quarterly sampling events for Calendar Year 2025 (January, April, July, and October) of five (5) groundwater wells (MW -21 S, MW -495, MW -505, MW -51 S, and MW - 52S) and four (4) surface water sample sites (SW -LCI, SW-LC3, LC-SW4, and LC-SW6) for the C&D debris disposal facility and at seven (7) groundwater monitoring wells (MW -3S, MW - 145, MW -44S, MW -44I, MW -535, MW -54S, and MW -54I) and four (4) surface water samples (C5 -SWI, SW -MW -145, SW -MW -53S, and SW -MW -54S) for the Class I landfill. The January and July sampling will be performed as part of the semi-annual sampling program under Phase 2 for the C&D debris disposal facility and assumed to take three (3) additional days to complete. The April and October data collection and sampling will each take four (4) days to complete. Geosyntec will deliver the samples to Eurofins laboratory for analytical testing under the SWDD's contract (i.e., Eurofins will directly invoice the SWDD for laboratory charges). For the C&D debris disposal facility, the quarterly assessment monitoring samples (including those collected in January and July) will be analyzed for the routine monitoring parameters listed in Paragraph 8 of the WQMP (C&D Permit) plus arsenic and benzene. For the Class I landfill, the quarterly assessment groundwater monitoring samples will be sampled for parameters as required by subparagraph 62-701.510(6)(a)3, F.A.C. The surface water samples will be screened for field parameters. Geosyntec will assist the SWDD in coordinating the analytical testing activities with Eurofins, notify the FDEP prior to sampling as required by the WQMP, review and evaluate the analytical test results, and prepare a letter report for each quarterly assessment monitoring event. The reports will be submitted in draft forms to the SWDD for review and comment and will be finalized, with the SWDD's comments implemented, for submittal to the FDEP. Any changes to the monitoring and reporting requirements that might be requested by the FDEP based on the results of the quarterly assessment monitoring will be performed under Phase 7 below.
