Mehta, P.E. 27 April 2021 Page 2 PROJECT BACKGROUND Ge®syntecc' consultants As part of the long-term monitoring activities for the identified CVOC plume associated with the South Gifford Road Landfill, a network of monitoring wells will require sampling on an annual or semi- annual basis to: (i) confirm that the CVOC plume is not migrating by monitoring the lateral and vertical extent; (ii) evaluate the impact of source and dissolved plume bioremediation to assess CVOC plume centerline concentrations over time; and (iii) :assess the impact of biological and physical natural attenuation processes on CVOC plume degradation. In consideration of the ongoing natural attenuation processes occurring at the site, the enhancement of these biological processes via the injection of an electron donor was proposed and agreed to in concept by the FDEP in correspondence dated 2 August 2006. In response to FDEP's request and supported by groundwater monitoring results, Geosyntec conducted an injection event in 2017 [Remedial Action Plan Modification Addendum No. 3 (RAPM 3)] to remediate recalcitrant CVOC groundwater impacts in the former source area. Semi-annual performance monitoring associated with bioremediation implementation was conducted from 2017 to 2020 at monitoring wells GR-MW30B and GR-MW37B and six additional monitoring well locations for analysis of CVOCs, dissolved gases, TOC, and/or microbial populations (Dhc and vcrA). In April 2021, FDEP approved to discontinue performance monitoring at GR-MW30B and GR-MW37B, discontinue analysis of dissolved gases, TOC, and microbial populations (Dhc and vcrA) at six additional monitoring well locations, and discontinue CVOC sample collection at five monitoring well locations where CVOCs had not been detected for at least three consecutive sampling events. Semi-annual groundwater monitoring for CVOCs only at 42 monitoring well locations will be conducted in 2021, as well as semi-annual reporting. PROPOSED SCOPE OF WORK The proposed scope of work consists of semi-annual groundwater monitoring and reporting and related activities to be performed on behalf of IRC SWDD at the Former South Gifford Road Landfill. For the purpose of budgeting, the scope of work has been divided into the following tasks: • Task 1 — Project Management; • Task 2 — Meetings/Regulatory Interaction; • Task 3 — Annual Pollution Remediation Liabilities Evaluation; • Task 4 — Semi -Annual Sampling Activities; and • Task 5 — Data Evaluation and Semi -Annual Reporting. The remainder of this section presents a general description of the activities to be performed in each task. FR0766\XR21012 engineers I scientists I innovators Mr. Himanshu H. Mehta, P.E. 27 April 2021 Page 3 Geosynte& consultants Task 1 — Proiect 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. The budget includes five hours per sampling/reporting event and one hour per month for the project manager (22 hours total), one hour for the senior principal - in -charge, and one hour per month (12 hours total) for the administrative assistant. Task 2 — Meetings/Regulatory Interaction: Under this task, Geosyntec will prepare for and attend up to two meetings, with IRC SWDD, FDEP, and/or:1RC Board of County Commission, as necessary. It has been assumed that one of these meetings will be in person and one meeting will be by video or conference call. Also, under this task, four hours has been included for the senior principal -in -charge to provide ongoing support to IRC SWDD related to interaction and negotiation with FDEP. Task 3 — Annual Pollution Remediation Liabilities Evaluation: As requested by IRC SWDD, under this task, Geosyntec will prepare the annual environmental liability evaluation. This document is prepared annually in response to Governmental Accounting Standards Board Statement No. 49 (GASB No. 49), Accounting and Financial Reporting for Pollution Remediation Obligations, which requires the inclusion and calculation of pollution remediation obligations. The objective of GASB No. 49 is to enhance the usefulness and comparability of pollution remediation obligation information reported by state and local governments. It has been assumed that the report will include evaluation of two sites, including South Gifford Road Closed Landfill (4701 41St Street) and Former Premier Citrus Property (375 82nd Street). In addition, two hours have been included for a Florida registered professional engineer to conduct an independent review of the liability evaluation. Task 4 — Semi -Annual Sampling Activities: Under this task, Geosyntec will perform 2021 field activities related to the performance monitoring and plume groundwater monitoring. The semi-annual activities will include field preparation, groundwater sampling, and water level measurements. Field preparation activities will include scheduling and staffing, subcontracting, coordination with the analytical laboratory, field equipment preparation, procurement of Passive Diffusion Bag (PDB) samplers, and notifying FDEP and Vero Beach Municipal Airport of the field schedule. Geosyntec will perform the groundwater sampling activities associated with the CVOC plume monitoring well network. Sampling activities in 2021 will be completed with a combination of PDB samplers and traditional low -flow sampling techniques and will transition to PDB samplers only in 2022. PDBs are anticipated to be purchased from EON Products, one of the few suppliers of this type of passive sampling device. Groundwater sampling activities will be executed using a two -person sampling crew and will be performed in general accordance with the FDEP Standard Operating Procedures (SOPS). The proposed summer 2021 field event (tentatively scheduled for June) will include sampling of nine monitoring wells (seven wells using PDBs and two wells with traditional sampling techniques). The summer 2021 field event is budgeted to include one-half day for groundwater sampling activities and one day for PDB deployment for the next sampling event (total of one and one-half [ 1.5] field days each with two persons). The proposed winter 2021 field event F 80766=21012 engineers I scientists I innovators Mr. Himanshu H. Mehta, P.E. 27 April 2021 Page 4 Geosyntec D Consultants (tentatively scheduled for December) will include sampling of 42 monitoring wells (all using PDBs). The winter 2021 field event is budgeted to include a total of two and one-half (2.5) days (with two persons) for groundwater sampling activities and PDB deployment for the summer 2022 field event. Consistent field documentation and field protocols will be utilized to develop reliable data to support the natural attenuation evaluation for the groundwater :plume. The groundwater samples will be analyzed in accordance with the sampling plan summarized in the 2020 Annual Groundwater :Monitoring Report. Quality control samples are proposed to be collected at a rate of 5% of total samples as required by the most recent FDEP SOPs. Geosyntec will conduct a complete round of groundwater level measurements concurrent with each semi-annual groundwater sampling event (budgeted for one day with two -person field team for each event). Depth to groundwater measurements will be recorded to the nearest 0.01 -ft in each monitoring well, including existing monitoring wells and applicable City of Vero Beach wells (assumed up to 95 wells per event). Due to wet site conditions and difficult access to certain well clusters, costs for rental -of a utility task vehicle are included for one day of groundwater level measurements and one day of sampling per event (4 total days). It is anticipated that purge water (investigation -derived waste [1DW]) will be containerized in 55 -gallon polyethylene drums and temporarily staged on Site for characterization prior to removal and disposal. Costs are included herein for purchase of one 55 -gallon :polyethylene drum and for one-half day of drum disposal oversight for one person. During the monitoring well inventory during the winter 2020 field event, Geosyntec personnel observed damage to one monitoring well, GR-MW06C, and maintenance activities are necessary to 'replace one bollard and repair the above ground polyvinyl. chloride (PVC) well casing which needs to be reattached to the aboveground portion of the well casing. Geosyntec will provide oversight for a subcontractor to make the repairs. Costs are included for one day of oversite (with one person) and for subcontractor costs. A Florida -licensed surveyor will survey the repaired monitoring well and :monitoring well GR-MW37B, installed in 2017. Overall, for field activities, budget has been included for seven and one-half field days for one person, six field days for a second person, (i.e., 13.5 man days); mobilization time for field personnel, and associated field expenses for sampling. Task 5 — Data Evaluation and Semi -Annual Reporting: Under this task, Geosyntec will perform data evaluation activities and reporting. The reporting includes preparation of one summer 2021 report (simplified format) and one winter 2021 report for submittal to FDEP. The summer 2021 report will be a letter report with attachments, including a monitoring well location map and tables of the field and laboratory results. Data evaluation activities for the summer 2021 report VR0766\XR2 1012 engineers I scientists I innovators Mr. Himanshu H. Mehta, P.E. 27 April 2021 Page 5 Ge®syntec d consultants will include database management, screening results against applicable regulatory criteria, and summary data table preparation. This report is due to FDEP by 31 July 2021. The winter 2021 report will be consistent with the groundwater monitoring reports historically submitted to FDEP for this Site and the data evaluation activities will include database management, screening results against applicable regulatory criteria, GIS figure preparation, time trend analyses, and/or statistical data analyses. The winter 2021 annual report will be supported by attachments containing Chain -of -Custody sheets, field notes and observations, water sampling logs, maps, graphs, analytical results, quantitative statistical evaluation,. and other applicable materials. As part of the statistical analysis, trend analysis graphs showing temporal concentrations of constituents and a summary of the Mann -Kendall statistics will be included to identify increasing, decreasing, or no trends in groundwater constituent concentrations. Historical data summaries will be included for monitoring wells recommended for removal from the monitoring'plan. The draft summer and winter 2021 reports will be submitted to IRC SWDD for review prior to submittal to FDEP. Each final report will be signed and sealed, by a Florida registered professional engineer or geologist. SCHEDULE The semi-annual groundwater sampling events will be tentatively conducted in June and December 2021 as described herein. Reports will be submitted to FDEP to meet required deadlines. BUDGET ESTIMATE A budget estimate for the scope of work outlined in Tasks l through 5 of this proposal is summarized in the following table, and a detailed budget estimate is provided as Attachment A. The budget estimate presented in this proposal is based on Geosyntec's understanding of the project requirements, our experience gained from executing similar tasks for SWDD since 2002 at the Site, and experience with groundwater monitoring and reporting activities at similar facilities. Geosyntec will not exceed the budget estimate without prior approval and written authorization from IRC SWDD. Due to reduction in the number of monitoring wells in the FDEP-approved sampling plan, discontinuation of certain laboratory analyses, and sampling only with PDBs versus traditional purging methods, the overall professional service hours were reduced by 10%.
