PROJECT BACKGROUND

Dry cleaning operations at Pugh’s Dry Cleaners began in 1948 and utilized a petroleum-based solvent. In 1965, Pugh’s switched to tetrachloroethene (PCE) as the drycleaning solvent, which was stored in an AST located inside the building. Based on documented impacts from the drycleaner, the facility was accepted into the Florida Drycleaning Solvent Cleanup Program in August 1998, and assessment activities by others commenced in December 2002. The assessment results revealed impact at levels requiring remediation and a soil vapor extraction (SVE) system was implemented. PSI took over running the SVE system in 2011 due to contractor turnover.

The Department then requested that the SVE system be shut down due to the drycleaner’s continued use of PCE.

The property changed ownership in 2016 and switched from PCE to a non-chlorinated solvent. The SVE system was re-started in October 2016 and is currently operating. The groundwater remains impacted with PCE at elevated concentrations.

A groundwater remediation strategy was designed incorporating In Situ Chemical Oxidation to reduce concentrations of COCs in groundwater. The remediation activities were implemented with a Regenesis product Persulfox which was applied in 22 injection wells (screened intervals 30 – 40 feet, and 58 – 68 feet). Two separate injection activities were conducted, one in September 2020 and the second injection in December 2020. Post injection monitoring is continuing with some groundwater contaminant rebound occurring.

The drycleaning business has relocated and the building is currently being used as a drop-off only. This was confirmed in September 2023 and in January 2024. Based on the tenant space being vacant, we conducted additional soil sampling inside the building to potentially conduct an interim source removal inside. The FDEP Waste Site Cleanup Section has also recommended we proceed with this course of action. The soil confirmation sampling was recently completed (February 2024) and a report is being developed to present the results.

PSI developed an Interim Source Removal Plan for excavation of soils in February 2025 however after discussions with the FDEP and the complexity of excavation activities within the restroom area, structural evaluation and potential requirement for additional support of load bearing walls, the FDEP has opted not to proceed with interior excavations. Based on the current radial placement of existing SVE wells, location of soils with commercial/industrial SCTL exceedances, and in lieu of excavation activities, PSI recommends installation of additional SVE wells within the area exhibiting the greatest VOH impacts and installation of a 1 horsepower blower for use in active venting. SVE wells should be installed with the intent to be used for active/passive venting and SVE operation to allow the system to push/pull soil vapors while mitigating preferential pathways.

PSI proposes modification of the existing SVE Interim Source Removal Plan to enhance VOH remediation activities in the vadose zone. PSI has developed this cost estimate and level of effort to modify the existing plan.

PROPOSED SCOPE OF WORK

This proposal consists of modifying the existing SVE Interim Source Removal Plan at the referenced site.

Specifically, the proposed scope of work consists of the following subtasks:

1. Project Management

This scope is provided for in the template worksheets.

2. Interim Source Removal Plan (ISR Plan)

The SVE ISRP Modification will enhance soil vapor exchange within the area of greatest VOH impacts and will not directly address groundwater quality. The presumptive remedy for remediation of impacted soil at Pugh’s Cleaners site is soil vapor extraction, based on previous experience, feasibility, implementability, reliability, operations and maintenance (O&M) requirements, and cost.

Calculations will be generated to determine the design criteria and equipment selection for an air injection blower/compressor. Updated figures will include piping and instrumentation diagram (P&ID) and manifold detail with tie in locations and equipment placement.

Due to the change in operation and enhanced recovery efforts, the report will include operation parameters, proposed soil vapor sampling and analysis, treatment considerations and itemized cost estimates for project capital, and the implementation schedule. The design will be signed and sealed by a Florida Registered Engineer in accordance with Chapters 471, Florida Statues. The report will incorporate specific recommendations and provide opinions based on professional experience in order to achieve the most efficient endpoints. We understand that the Department’s goal is to achieve aggressive contaminant reduction in an efficient and cost-effective method.

The deliverable and invoice schedule are presented below and are based on receipt of a Task Assignment prior to December 15, 2025.
