Within that document, Cardno had proposed installation of four (4) additional monitor wells to delineate the lateral extent of documented groundwater impacts of perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) above the current Provisional Cleanup Target Levels (CTLs) and U.S. 0 EPA Health Advisory Levels (HALs) of 70 nanograms per Liter (ng/L). FDEP has 0 reviewed the May 2020 SAR report and proposal, and has requested: a) an additional groundwater monitor well to the north of the northern borrow pit (5 wells total), b) two 0 marine surface water samples from the water bodies north of the peninsula on which the 01 Joe London facility resides, and c) an evaluation of leachability of PFAS constituents based on prior exceedances of the leachability soil cleanup target level (SCTL) that were detected at several shallow soil sample locations. �l Cardno has reviewed the FDEP comments with your staff, and provided a direct 0 response to FDEP on September 24, 2020. The following technical and cost proposal is for the completion of the requested activities, as proposed within the September 24, 2020 responses. Proposed Scope of Work Task 1 —Surface Water Assessment Cardno with collect two (2) surface water samples from the marine surface water body to the northeast and northwest of the Joe London facility, for analysis of PFAS constituents. These U G:\DES\ENV\Proposal\2020\Monroecounty\Supplementl_PFAS Assessmentprop.Docx lAttachmen7 Packet Pg. 797 C.22.a Kevin Wilson Page 2 September 28,2020 06 samples will be collected at or near low tide, with tide table documentation provided within the 0 associated reporting. d E Task 2 —Soil Assessment An exceedance of the residential direct exposure soil cleanup target level (R-SCTL) was encountered at a single soil sample location at the Joe London Training Academy Site; however, the leachability to groundwater SCTL (L-SCTL) was exceeded at several locations. Per FDEP's request to investigate the relationship between L-SCTL results and GCTL exceedances, and to better delineate impacts associated with the single R-SCTL exceedance location, Cardno proposes to collect step-out delineation samples to the north, south, east, and west of the R-SCTL exceedance location (SS-8), and to analyze these samples for both total PFAS concentrations and synthetic precipitation leaching procedure (SPLP) analysis. In addition to these four sample locations (2 depths each), Cardno will also collect 2 soil samples from a single soil boring located immediately adjacent to well MW-1 and to run SPLP analysis on these two depth interval samples. These data will be used to draw conclusions regarding the potential leaching of PFAS from shallow soil (and limestone), throughout the site. Task 3 —Groundwater Assessment Cardno proposed four additional monitor wells to delineate PFAS impacts to groundwater within the May 2020 SAR; however, FDEP requested an additional monitor well to the north of the borrow pit to the north. As a result, Cardno will install five (5) monitor wells to a depth of approximately 12 feet below land surface (ft bls), and will sample the wells for PFAS constituents of concern. After wells are installed and developed, the top of casing elevation of all monitor wells will be i surveyed relative to an arbitrary datum to allow determination of groundwater flow at the site. Groundwater elevation data will be collected from all monitor wells prior to sampling of the five new wells. 0 Task 4— Data Evaluation and Report Preparation (Supplemental SAR Report) 0 The information obtained during implementation of Tasks 1 through 3 will be evaluated and discussed within a Supplemental SAR document. Sample results will be summarized in tables and on figures, and associated Iithologic logs, groundwater sampling logs, and laboratory 01 analytical reports will be included within the document. Conclusions and recommendations will also be provided in the report, including a preliminary recommendation regarding the need for additional sampling or potential remedial measures. �I Cost Proposal 0 This cost proposal assumes two days total for mobilization and demobilization to and from the site (Drilling Contractors and Consultants), four days of borings and well installations and development, and two additional days to complete subsequent groundwater sampling. Cardno is providing the following cost proposal as a lump sum (LS) proposal that includes all subcontractor services and a limited amount of activity by Cardno. Substantial budget remains on the current cost-plus-multiplier task assignment and Cardno will bill field activities for this proposal to the existing purchase agreement, reducing the cost of this LS proposal.

This includes residential direct exposure (RDE) soil cleanup target levels (SCTLs) for PFOS at one sample location, and leachability SCTL exceedances for PFOS and/or PFOA at numerous locations. The groundwater CTL of 70 nanograms per Liter (ng/L) for PFOS and PFOA (either individually or combined) was also exceeded in each of the two groundwater samples collected. Preliminary surface water standards were also exceeded during this investigation. Based on these results, the FDEP submitted a 0 letter to Chief James Callahan (Monroe County Fire Rescue) dated November 8, 2019, requiring that the responsible party initiate site assessment activities within 60 days of discovery. This letter also indicated that, as the potentially responsible party for this site, Monroe County/Monroe County Fire Rescue is subject to the requirements for assessment and remediation of contamination under Chapter 62-780, F.A.C.

However, the proposal can be modified to a lump sum (LS) cost basis, if preferred by the County. Activities performed by Cardno for this project will be consistent with our current Agreement with Monroe County to Furnish Professional Consulting Services (executed 6 December 19, 2018). Proposed Scope of Work Task 1 —Prepare Draft Assessment Plan for FDEP Review —Obtain Access Agreements - Geophysics Cardno will meet with Fire Training Center representatives to discuss historical training activities 0 with respect to PFAS use at the site, and will review information provided by FDEP regarding PFAS impacts to soil, groundwater, sediment, and surface water; groundwater and soil characteristics; well construction details, etc.; in order to refine the proposed assessment plan for the site. Cardno assumes that a meeting with FDEP will be conducted to review the proposed scope of work, and to discuss FDEP's long range expectations regarding offsite delineation and remediation requirements. This task will also include initial project administration and subcontracting services, as well as preliminary clearing of proposed drill locations via a geophysical survey. Geophysical clearing of drill locations may be omitted if detailed records of underground utility locations are available. Task 2 —Soil and Surface Water Assessment FDEP Consultants collected shallow soil samples from eleven (11) soil borings, with leachability U SCTLs exceeded in at least one sample interval at all eleven locations. However, the residential direct exposure (RDE) SCTL was only exceeded at one location. Based on these results, Cardno proposes to advance shallow soil borings at the four (4) locations shown on Figures 1 and 2, and to collect samples from each location for PFAS analysis. The primary purpose of these samples is to refine the delineation of leachability SCTL exceedances to the southwest (one boring), and (more importantly) to delineate the RDE SCTL exceedance near the northwest corner of the site. Soil samples will be collected from two depth intervals (0 to 0.5 ft below land surface (bls) and 0 from between 0.5 ft bls and the water table), for analysis of PFAS compounds. A total of eight (8) soil samples will be analyzed for PFAS, plus one equipment blank, one field blank, and (potentially) one matrix spike/matrix spike duplicate sample (11 soil samples total). r In addition to soil samples, Cardno will collect up to four (4) surface water samples for both PFAS U and chloride analysis. It is anticipated that surface water samples will be collected from three different borrow pit locations: near the same location as the prior surface water sample, near the en central portion of the borrow pit on the south bank, and near the center of the eastern bank of the U) borrow pit. A surface water sample will also be collected from the Florida Bay shoreline, pending discussions with Monroe County representatives. Task 3 —Groundwater Assessment FDEP installed two temporary monitor wells to a depth of 12 ft bls during the initial site investigation. The Provisional GCTL for both PFOS and PFOA (70 ng/L) were exceeded at both G:\DES\ENV\Proposal\2020\Monroecounty\PFAS Assessmentprop.Dou Packet Pg. 808 C.22.c Kevin Wilson Page 3 December 23,2019 Fn well locations, with combined PFOS and PFOA concentrations of 1,540 ng/L and 17,200 ng/L, Q. for wells TMW-1 and TMW-2, respectively. These elevated concentrations, coupled with the 06 high solubility (miscibility) of PFAS compounds in groundwater indicates that a significant PFAS plume may be present at this site. As a result, Cardno is proposing installation of nine (9) permanent monitor wells to a depth of approximately 12 ft bls, as well as two deeper monitor wells (to approximately 30 ft bls), at locations shown on Figure 3. One of the nine shallow wells is proposed on adjacent, undeveloped property to the west, and to additional shallow wells are proposed outside of the facility fence to the south and southeast. Site access agreements or 6 right-of-way permits may be required for these three well locations. Two deeper monitor wells are designed to provide evaluation of the vertical extent of PFAS impacts to groundwater, near the locations of the previous temporary shallow wells. In order to prevent potential drag-down of contamination during drilling activitieis, a temporary surface casing will be used to isolate the shallow borehole from the deeper borehole during construction. Based on the number of wells proposed, the proposed depth of deeper wells at the site, and the extensive limestone Iithology present, Cardno is proposing the use of Sonic drilling techniques to minimize potential issues with borehole advancement, and to speed up the drilling and well installation processes. Additionally, due to the exceedingly low level GCTLs associated with PFAS, high level decontamination procedures will be implemented to minimize the potential for cross contamination between boring or sample locations. Once installed and developed, each of the eleven (11) new monitor wells, will be sampled for PFAS constituents via method 537(modified) (includes 21 analytes with PFOS and PFOA). Cardno will also conduct chloride analysis on select wells to determine if alternative GCTLs might be applicable to the site. In addition to the 11 well samples, two (2) equipment blanks, two (2) field blanks, two (2) sample duplicates, one (1) trip blank, one (1) matrix spike/matrix spike duplicate sample (potentially), and two (2) investigation-derived waste samples will be M analyzed for PFAS constituents (total of twenty-one samples). Samples will be collected in compliance with the FDEP Standard Operating Procedures Manual (DEP-SOP-001/01), and Draft SOPs and Draft PFAS Sampling SOPs, dated October 2019. After wells are installed and developed, the top of casing elevation of all monitor wells will be surveyed relative to an arbitrary datum to allow determination of groundwater flow at the site. r_ 0 Task 4— Data Evaluation and Report Preparation (Site Assessment Report (SARI) The information obtained during implementation of Tasks 1 through 3 will be evaluated and discussed within a SAR document. Sample results will be summarized in tables and on figures, and associated Iithologic logs, groundwater sampling logs, and laboratory analytical reports will be included within the document. Conclusions and recommendations will also be provided in U the report, including a preliminary recommendation regarding the need for additional sampling or potential remedial measures. en U) Cost Proposal This cost proposal assumes two days total for mobilization and demobilization to and from the site (Drilling Contractors and Consultants), five days of borings and well installations and development, and two additional days to complete subsequent groundwater sampling.
