Re: Proposal for Annual Groundwater Monitoring and Reporting Corman Cleaners 3464 SE Dixie Highway Stuart, Martin County, Florida 34997 Terracon Proposal No. PHB257020

Dear Mr. Sostre:

Terracon Consultants, Inc. (Terracon) appreciates the opportunity to submit this proposal to Florida Department of Environmental Protection (FDEP WCP) to conduct Groundwater Monitoring and Reporting Services at Cormans Cleaners (ERIC_4924) located at 3464 SE Dixie Hwy, Stuart, Martin County, Florida.

Scope of Services

Groundwater Monitoring services to include:

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

Subtask 2 - Field task planning, mobilize to site, perform annual groundwater sampling and laboratory analysis of shallow monitoring wells and piezometers MW001, MW015, MW016, and PZ003 for VOHs by EPA Method 8260. This subtask also includes subcontractor and oversite costs to perform subcontractor coordination and management of IDW.

Review data and prepare a Groundwater Monitoring Report including updated tables and groundwater flow and concentration exhibits.

See attached LOE for details.

Proposal for Annual Groundwater Monitoring and Reporting

Corman Cleaners | Stuart, Martin County, Florida 34997

May 16, 2025 | Terracon Proposal No. PHB257020

Facilities | Environmental | Geotechnical | Materials

Schedule Delivery of Annual Groundwater Monitoring Report within 20 business days following receipt of laboratory results.

Compensation See attached CEF for details

Scope of Services

During the July 2024 sampling event, groundwater laboratory analysis reported PCE in the groundwater sample collected from interior monitoring well MW001, screened 4 to 9 feet below ground surface (bgs), at a concentration of 25 micrograms per liter ( g/L) for PCE.

This concentration represents an increase above the 7.2 g/L PCE reported in MW001 during the December 2022 sampling event conducted by Terracon and is the highest PCE concentration reported to date.

Based on review of the historical data, the PCE concentrations reported in MW001 appear to be fluctuating with seasonal variations in groundwater elevations which may indicate a source within the screen interval is still present and contributing to these exceedances.

1,1-dichloroethene (1-1 DCE) was detected in intermediate monitoring wells MW010 and MW012 above GCTLs, however the detection is likely related to an off-site plume that was investigated by the FDEP Site Investigation Section (SIS). All remaining volatile organic halocarbons (VOHs) were reported below the method detection limit (MDL) or the respective Groundwater Cleanup Target Level (GCTL) for the July 2024 sampling event. Terracon recommended continued annual groundwater monitoring of shallow monitoring wells and piezometers MW001, MW015, MW016, and PZ003, and to revisit the vinyl chloride and 1,1- DCE (offsite source plume) and potentially approach SIS for additional funding to investigate this plume.

This sampling event represents the baseline event before SVE installation and system start

up. The TA DC024E to implement the SVE install was authorized and is scheduled for construction.

Deliverables

The Groundwater Monitoring Report will detail and summarize the sampling activities, field data, and include tables and updated exhibits. Conclusions and recommendations will include a summary of results and recommendations for future sampling or additional investigative assessments.

Schedule

It is estimated that the annual event could be conducted within two to three weeks from TA authorization and email deliverable issued within 20 business days of receipt of laboratory analytical results.

Closing Remarks

Terracon services will be conducted in accordance with the terms and conditions, contained within the DEP Waste Cleanup Program (WCP) Contract No. HW687, executed January 5, 2022. It is understood that the Task Assignment will be issued to authorize us to perform this work.

We appreciate the opportunity to provide this proposal and look forward to working with you on this project. If you should have any questions or comments regarding this proposal, please contact either of the undersigned at 772-343-9787.

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

Ms. Endicott:

The price for the transportation and disposal (T&D) of one (1) 55-gallon drum of non-hazardous PFAS/PFOS water from your site in Vero Beach, FL is $195.00 per drum.

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.
