The FDEP project manager is Sarah Aduwa (850-245-8973), and the contractor's project manager is Nicholas Barnes (813-379-4388).

The total contract value is $65,267.78, comprising a fixed unit rate of $61,067.78 and cost reimbursement of $4,200.00 for utilities not to exceed that amount. Payments are structured by deliverable across seven subtasks: Subtask 2 (System Restart and Groundwater Monitoring Field Deliverable) for $13,440.61 due August 27, 2025; Subtask 3 (Months 2-3 O&M) for $8,775.90 due November 25, 2025; Subtask 4 (Months 4-6 O&M and Semi-Annual Report) for $12,123.76 due February 26, 2026; Subtask 5 (Months 7-9 O&M) for $8,775.90 due May 28, 2026; Subtasks 1 & 6 (Project Management and Annual Report) for $17,711.61 due September 17, 2026; and Subtask 7 (Utilities) for $4,440.00 due September 17, 2026. The original cost estimate was $68,170.99, which was successfully negotiated down to $65,267.78, resulting in cost savings of $2,903.21 with a reduction from 330 to 311 total labor hours.

Ms. Sarah Aduwa Florida Department of Environmental Protection Waste Site Cleanup Section 2600 Blair Stone Road Tallahassee, FL 32399-2400

Subject: Scope of Work and CEF/LOE

Soil Vapor Extraction System O&M (1 Year) Colonial Touch of Class Cleaners 4552 Lake Worth Road Greenacres, Palm Beach County, Florida 33463 FDEP Facility ID NO. ERIC_5222

Dear Ms. Aduwa:

Geosyntec Consultants, Inc. (Geosyntec) has prepared this proposed Scope of Work (SOW) and Level of Effort (LOE) for groundwater monitoring, soil vapor extraction (SVE) system restart, and 12 months of operation and maintenance (O&M) at the Colonial Touch of Class Cleaners Site located in Greenacres, Florida (ERIC_5222).

The O&M activities following system restart are subdivided into subtasks by quarter. The major scope elements are outlined below and will pertain to multiple subtasks in some cases. Each subtask will be outlined separately thereafter. A cost estimating form (CEF) and LOE is provided as Attachment A.

SVE System Restart

The SVE system has been off since June 2024 to enable supplemental source area assessment including additional MAGs testing to support preparation of a Remedial Alternatives Evaluation (RAE). During the April 29, 2025 site review meeting with FDEP, it was decided that the system should be restarted to evaluate additional mass removal and assess other optimizations prior to re-advancing the Site towards a RAE. During the restart, FDEP requested vacuum data be collected to evaluate if there are any dead zones in the vapor recovery radius of influence and that vapor samples be collected from the combined influent, system effluent, and select vapor extraction wells (VEWs).

Groundwater Sampling Select site monitoring wells shall be sampled to evaluate current groundwater quality, coincident with SVE system restart. The proposed monitoring wells for sampling include MW001, MW002, MW003, MW005, MW006, MW008, and MW009. A figure showing the locations of these wells and prior analytical results is provided as Attachment B. Prior to collecting groundwater samples, depth-to-water measurements will be collected from the well network. Groundwater samples will be analyzed by a fixed-based, certified laboratory for volatile organic halogens (VOHs) using EPA Method 8260. The analytical results will be tabulated and provided in a field deliverable, with an evaluation of the results provided in a Semi-Annual O&M Report.

Monthly SVE System O&M Tasks Geosyntec will conduct monthly O&M visits to the Site following SVE restart. Geosyntec personnel will perform the following tasks during each monthly O&M visit.

Recording vacuum, pressure, and temperature readings at the SVE blower;

Recording air flow rates at the blower and vapor extraction wells (VEWs);

Documenting active and passive VEW operation and adjustment of active and passive

VEWs, as necessary;

Recording vacuum readings at VEW01 through VEW04 and select monitoring wells;

Draining fluids accumulated in the moisture separator and disposing of fluids in a 55-gallon drum as investigation derived waste (IDW);

Collecting groundwater level measurements in select monitoring wells;

Inspecting and cleaning (as needed) the equipment compound;

Inspecting water entrainment and adjustment of VEW wellhead vacuums (if necessary) to minimize water entrainment; and Performing periodic equipment maintenance activities.

Vacuum measurements will be collected at each of the system vacuum gauges during each O&M visit and select VEWs, MAGS wells, and MW wells. The vacuum monitoring data will be used to assess the actual vacuum ROI at the Site. The system will be adjusted to optimize the mass recovery rates through active and passive operations of VEWs. The monthly system O&M activities will be documented in a site-specific O&M log.

Soil Vapor Sampling Upon SVE system restart, Geosyntec will collect samples from the influent, VEW003, and VEW004. Thereafter, influent samples will be collected on a quarterly basis. Air samples will be collected in a Summa cannister and analyzed by a fixed-based, certified laboratory by United

States Environmental Protection Agency (EPA) Method TO-15. Additional soil vapor samples from the VEWs may be collected on an as needed basis, following discussion with FDEP.

IDW Generation IDW assumed to be generated includes purge water collected during groundwater sampling event, moisture captured in the SVE system moisture separator, and the previously utilized granular activated carbon (GAC). Subcontractor bids for IDW transport and disposal are included in Attachment C.

SVE System O&M Status Reporting Monthly Email Summaries and Semi-Annual Reports (i.e., following Month 6 and Month 12) will be prepared to document O&M activities. The O&M reports will include the following:

O&M activities performed during the reporting period;

Calculated mass of VOHs removed by the SVE system during the reporting period, and cumulative total removed since startup;

SVE system hours of operation during the reporting period;

Information regarding the depth-to-groundwater (in summary table form with one set of representative data depicted graphically);

Information regarding any repairs and/or modifications made to the SVE system;

Vacuum radius of influence data (in summary table form with one set of representative data depicted graphically and

Results of laboratory analyses of air samples (System Restart, Months 3, 6, 9, and 12) and groundwater monitoring well samples in tabular and graphical form;

Recommendations pertaining to the continued operation and/or optimization of the SVE system (including cycling VEWs as active or passive).

Utilities Monthly electrical utility bills have been estimated at $350 per month.

Subtask 1 – Project Management

Subtask 2 – SVE System Restart and Groundwater Monitoring

This subtask includes restart of the SVE system and an annual groundwater monitoring event, as discussed during the 29 April 2025 annual site review meeting. Seven groundwater samples will be collected from the monitoring wells outlined above, and three vapor samples (influent, VEW03, and VEW04) will be sampled, as described above. Nick Barnes will assume responsibilities as the FL Professional Engineer and Project Manager; Nick will mobilize to the Site to conduct the SVE restart activities with a local field staff member who will be onsite to conduct groundwater sampling. The cost for the annual telemetry service fee from the equipment manufacturer, PRM Filtration, is included in this Subtask.

Subtask 3 – Quarter 1 (Month 1 to Month 3) O&M

This subtask includes costs for three months of O&M, including influent air sampling during Month 3 event.

Subtask 4 – Quarter 2 (Month 4 to 6) O&M and Reporting

This subtask includes costs for three months of O&M, including air sampling during Month 6, and the submittal of a Semi-Annual O&M Report that will include evaluation of the groundwater monitoring data generated during Subtask 1.

Subtask 5 – Quarter 3 (Month 7 to 9) O&M

This subtask includes costs for three months of O&M, including air sampling during Month 9, with monthly email summaries to FDEP.

Subtask 6 – Quarter 4 (Month 10 to 12) O&M and Reporting

This subtask includes costs for three months of O&M, including air sampling. This subtask also includes the submittal of an Annual O&M Report with final IDW manifests.

Nick, For your needs, I'd recommend the 200MB per month plan. It should be sufficient for basic alarm notifications and system status updates.

Let me know if you'd like me to get that set up for you.

Thanks Ian.

What would you recommend regarding the options below? I won’t need to frequently use the telemetry or make any adjustments remotely, I’ll just want to get notifications if the system goes down/has an alarm condition, etc.

Thanks, Nick
