PSI Proposal: 0552-446678

FDEP

March 18, 2025 www.intertek.com/building along with soil sampling for Soil Oxidant Demand (SOD) to assist in evaluating a groundwater remediation strategy.

An SVE system was installed in October 2009 by others and has operated intermittently since that time.

PSI has operated the system at varying cycling times since April 2012 to July 2016. The system was shut down due to the drycleaning business remaining in operation and use of PCE as their solvent. The property / tenant changed ownership in 2016 and switched from PCE to a non-chlorinated solvent fluid. The SVE system was subsequently re-started in October 2016 and operated until June 2021, then turned off in preparation for shutdown, along with confirmation soil sampling in June 2021. The results revealed soil impact inside the building that exceeded SCTLs (2480 mg/kg at SB016). The system was restarted in October 2021 and continues to exhibit contaminant mass recovery. A groundwater remediation strategy consisting of ISCO using Persulfox in 22 injection wells targeting 30 40 feet , then 58 68 feet deep, was completed in 2020 2021. Groundwater performance monitoring indicates groundwater contaminant reduction with a rebound in select wells. Soil confirmation sampling occurring in January 2024 confirmed the presence of VOHs in exceedance of commercial/industrial SCTLs remain beneath the building.

Per discussions with the FDEP, PSI recommends continued operation of the SVE system for the next 12 months along with groundwater monitoring in accordance with the RAP schedule.

PROPOSED SCOPE OF WORK

The proposal contained herein consists of utilities service and twelve-monthly O&M events with two report deliverables for the existing SVE system, quarterly email summaries, groundwater monitoring along with reporting. The results will be used to confirm system operations and evaluate mass recovery rates as compared to remedial design. Annual groundwater monitoring will also be conducted with the results incorporated into a RASS report. Specifically, the proposed scope of work consists of the following subtasks:

1. Project Management

This scope is provided for in the template worksheets.

2. Three Months of O&M (First Quarter)

Operations and Maintenance will be conducted on the SVE system. The work will be conducted as follows:

a. Mobilization to the site on a monthly basis.

b. Collect monthly vacuum and air flow readings from the SVE wells.

c. Collect monthly PID readings from SVE wells and total system influent.

d. Optimize system performance and recollect system readings as necessary to confirm enhanced system operation.

e. Collect quarterly system influent samples for analysis by Method TO-15.

f. Document system readings in the site specific O&M checklist.

g. Review and submit quarterly deliverable.

The Level of Effort for system repairs and the first quarter O&M is detailed in Subtask 2.

March 18, 2025 www.intertek.com/building

3. Three Months of O&M (Second Quarter)

O&M will be conducted once a month for three months as specified above. Air samples will be collected from seven of the individual wells and the influent and analyzed by TO-15. A summary of system conditions will be submitted to the FDEP each quarter.

The Level of Effort is detailed in Subtask 3.

4. Semi-Annual RASS Report

A Semi-Annual Remedial Action System Status Report will be developed which will include an evaluation of the collected information and data. The report will detail and summarize the monthly O&M information, along with summary tables, figures and a graphical depiction of the system performance.

Vapor sampling results will be submitted in the RASS report. The report will be prepared in accordance with the Technical Worksheets or similar guidance documents, developed by the FDEP Drycleaning Solvent Cleanup Program.

8. Utilities for remediation system operation

PSI used the previous utility costs at this project as well as from similar equipment at other sites as a basis for the annual costs. Utilities funded under the current Task Assignment end in March 2025. In order to keep the system running, PSI is requesting funding for a total of 14 months in order to cover April 2025 through May 2026 should authorization not be provided with enough time to complete O&M activities in May 2026 or O&M activities are postponed by 1 month. Utility reimbursement will be requested for months between Task Assignments and during authorized O&M activities prior to a request to shut the system down and discontinue service.

The Level of Effort for utilities is detailed in Subtask 8.

9. Groundwater Monitoring and Reporting

PSI will conduct the annual groundwater monitoring to evaluate current groundwater quality at the site.

The annual groundwater monitoring will be conducted for Volatile Organic Halocarbons (VOH), FLO-PRO and injection parameters only as previous monitoring in October 2023 for per- and polyfluoroalkyl (PFAS) compounds revealed no concentrations above the Provisional GCTL of 70 ng/L. The following will be conducted to facilitate the groundwater evaluation:

a. Mobilization to the site.

b. Collect groundwater elevation measurements at the 11 wells proposed for sampling.

c. Collect groundwater samples from monitor wells:

i. Shallow: MW011

ii. Intermediate: MW013, MW015, MW016, MW018, MW019, MW020, and

MW022

iii. Deep: MW004, MW005, and MW021.

d. Submit groundwater samples to a NELAC approved laboratory for analysis of VOHs via EPA Method 8260 and injection parameters (sulfate, TDS, Iron, Sodium, Manganese) from 3 wells (MW015, MW016, and MW018). Based on soil analytical samples collected in January 2024, monitoring wells will be analyzed for TRPH via FL-PRO during this sampling event.

e. Incorporate groundwater analytical data, physical parameters and groundwater elevation data into the RASS report.

The investigative derived waste (IDW) that will be generated during the annual groundwater monitoring includes the purge water from the monitoring wells which will be containerized in a 55-gallon drum for transport and disposal at an approved facility.
