FDEP Contract HW687 Terracon Proposal No PHD257001

Dear Mr. Sostre:

Terracon Consultants, Inc. (Terracon) appreciates the opportunity to submit this proposal to the Florida Department of Environmental Program (FDEP) Waste Cleanup Program (WCP) to conduct Groundwater Monitoring for Volatile Organic Halocarbons (VOHs) and conduct expanded groundwater sampling for per-and polyfluorinated substances (PFAS) analysis for the above-referenced facility.

Scope of Services

Subtask 1 - The costs associated with this subtask are calculated automatically at 13% of the direct labor costs of the remaining subtasks.

Subtask 2 –VOH Groundwater Sampling Field preparation, mobilize to site, and perform groundwater sampling and laboratory analysis of 7 existing monitoring wells (MW-2, MW-7D, MW-9, MW-10, MW-12, MW-13, and MW-16) for VOHs.

Review VOH results and prepare and Groundwater Monitoring Report including updated tables and groundwater flow and concentration exhibits and provide conclusions and recommendations.

Subtask 3 – Expanded PFAS Sampling Field task planning, mobilize to site, and perform groundwater sampling and laboratory analysis for PFAS of 8 monitoring wells.

Monitoring wells proposed for PFAS sampling: (MW-1, MW- 3D, MW-5, MW-7D, MW-8, MW-9, MW-10, and MW-16) PFAS analysis only bolded

Proposal fo Annual Groundwater Monitoring Report Village Cleaners (Former), ERIC_5205 West Plam Beach, FL March 28, 2025 Terracon Proposal No. PHD257001

PFAS samples are sent by overnight courier to FDEP’s laboratory for sample analysis.

Review PFAS results and prepare a report section to discuss results and provide conclusions and recommendations.

See attached LOE for details

Deliverable Deliverable Groundwater Monitoring Report in July 2025, tentatively, based on TA authorization and following receipt of laboratory results.

Compensation See attached CEF for details.

BACKGROUND GROUNDWATER

According to Tetra Tech’s 2021 Groundwater Monitoring Report, samples were collected from 10 monitoring wells. Three of the 10 monitoring wells sampled in the September 2021 sampling event exceeded the Chapter 62-777, Table I, Florida Administrative Code (F.A.C.) Groundwater Cleanup Target Level (GCTL) for vinyl chloride (8.50 μg/L from MW-9, 2.48 μg/L from MW-10 and 2.46 μg/L MW-13).

PCE and TCE were not found to be exceeding Chapter 62-777, GCTLs in any of the groundwater samples analyzed from the September 2021 sampling event. In addition, Cis-1,2 dichloroethene was detected in five of the 10 monitoring wells above the laboratory method detection limits (MDLs) but below the respective GCTL. Trans 1,2 dichloroethene was also detected in one of the 10 monitoring wells above the laboratory MDLs but below its respective GCTL. The remaining monitoring wells had no reported exceedances of drycleaning contaminants of interest (COIs) in groundwater during this monitoring period. All reported detections were reported below their respective target level prescribed in Chapter 62-777 for the September 2021 monitoring event.

Overall, where levels were detected above their respective GCTL (i.e., VC), the groundwater exhibited slight increases in concentrations from historical. These increases in VC concentrations coincide with decreases of PCE and TCE concentrations to below detection limits.

PFAS sampling was conducted at the site on August 22, 2023, for monitoring wells MW-1, MW-8, MW- 9, and MW-10. Analytical results reported Perfluorooctanic acid (PFOA) + perfluorooctanesulfonic acid (PFOS) above the FDEP Provisional Cleanup Target Level (PGCTL) in MW-1, MW-8, MW-9, and MW-10.

Expanded sampling of the PFOA+PFOS PGCTL exceedances was recommended to the FDEP during the email deliverable to define the horizontal extent and confirm if deeper investigation is warranted.

On October 17, 2024, Terracon prepared an Annual Groundwater Monitoring Report, during which in August 2024, 13 groundwater samples (MW1, MW-2, MW-3D, MW-6, MW-7D, MW-8, MW-9, MW-10, MW-12, MW-13, MW-14, MW-15 and MW-16) were collected and analyzed for drycleaning COIs. In addition, seven of the 13 wells that were sampled for drycleaning COIs (MW-1, MW-3D, MW-9, MW-12, MW-13, MW-14 and MW-16), with an additional three wells (MW-6, MW-8, and MW-15), were sampled for expanded PFAS screening. During the August 2024 sampling event, reported vinyl chloride was above the GCTL of 1 μg/L, in monitoring wells MW-7D, MW-9, MW-10, and MW-16. Overall, the groundwater concentrations reported for the drycleaning COIs in August 2024, appeared to be on a downward trend with slight increases in vinyl chloride and daughter products in source and downgradient wells. Combined PFOA and PFOS exceedances of the 70 ng/L PGCTL were detected in three of the 13 monitoring wells (MW-3D, MW-9 and MW-16), during the August 2024 sampling event.

Proposal fo Annual Groundwater Monitoring Report Village Cleaners (Former), ERIC_5205 West Plam Beach, FL March 28, 2025 Terracon Proposal No. PHD257001

SCOPE OF SERVICES

Based on the results of the October 17, 2024, Groundwater Monitoring Report, Terracon recommends collecting groundwater samples from 7 monitoring wells (MW-2, MW-7D, MW-9, MW-10, MW-12, MW- 13, and MW-16)for analysis of VOHs, of which 7 (MW-1, MW-3D, MW-5, MW-7D, MW-8, MW-9, MW-10, and MW-16)) will be sampled for VOHS and PFAS, in addition monitoring wells MW-1, MW-3D, MW-5, and MW-8 will be analyzed for PFAS only, for a total of 8 wells to be collected for PFAS monitoring during the sampling event.

Re: Non-Hazardous Drum Disposal of PFOS/PFAS Impacted Materials - West Palm Beach, FL

Ms. Endicott:

The price for the transportation and disposal (T&D) of eight (8) 55-gallon drums of non-hazardous PFAS/PFOS impacted soil and water from your site in West Palm Beach, FL is $195.00 per drum. Additionally, there is a one time profiling fee of $350.00. The total cost for the T&D of the eight (8) drums is $1,910.00.

Please ensure that all drum lids are properly secured and that drums are on a level surface like the surrounding area (i.e., not on a pallet, etc.). A single False Mobilization fee will apply if our driver is not able to locate a drum on site or if we are unable to access the property due to a locked gate, etc. This quote is valid for 90 days.
