Theresa Pepe Hazardous Waste Cleanup Section Florida Department of Environmental Protection 2600 Blair Stone Road Tallahassee, Florida 32399

Date: October 8, 2025 Subject: Natural Attenuation Monitoring Proposal

Former Imperial Laundry and Drycleaners 901 West Fairbanks Avenue Winter Park, Florida

Dear Ms. Pepe, Arcadis U.S., Inc. (Arcadis) is pleased to submit to the Florida Department of Environmental Protection (FDEP) the following proposal for Natural Attenuation Monitoring (NAM) activities at the Former Imperial Laundry and Drycleaners (Site), located in Winter Park, Florida. This proposal includes background information, a description of the proposed scope of work (SOW), and an estimated cost and schedule for their completion.

Site Background Arcadis completed Task Assignment (TA) #DC041B, which included the 2025 annual NAM sampling event (July 2025) and associated reporting. The City of Winter Park constructed a turn on the eastern portion of the former dry cleaning parcel in 2024. The Site was used to stage equipment and materials for construction activities. All of the monitor wells except MW005, were damaged and covered by restoration activities following construction of the turn lane. A professional surveyor staked the well locations and Arcadis personnel uncovered the wells on January 8, 2025. Monitor wells MW004, MW005, and MW008 were determined to be the only viable wells.

Based on observed damage to existing monitor wells from construction activities, monitoring wells MW007 and MW013 were destroyed and monitor wells MW001, MW002, MW003, MW009, and MW012 were abandoned by licensed driller Preferred Drilling Solutions Inc. on June 30, 2025. The same day, monitor wells MW001R and MW002R were installed to replace damaged and abandoned monitoring wells MW001 and MW002, and MW004 and MW008 were redeveloped.

The 2025 Annual NAM Report was submitted on August 8, 2025. Tetrachloroethene (PCE) was detected above the FDEP GCTL in the sample collected from monitor well MW002R (7.0 μg/L). Arcadis recommended continued monitoring of MW001R and MW002R. The FDEP reviewed the report and concurred with the recommendations in an email dated September 8, 2025.

2025.10 - Imperial NAM Proposal

2/3

Scope of Work

Task 1: Project Management This task consists of project management activities and health and safety efforts in relation to the completion of Tasks 2 through 4.

Task 2: NAM Field Event Q1

The proposed groundwater NAM program includes depth-to-water measurements and the sampling of two shallow monitoring wells. Depth-to-water measurements will be collected from all accessible site monitor wells and samples will be collected from MW001R and MW002R. The groundwater sampling activities will be performed per the FDEP standard operating procedures (SOP) (DEP-SOP-001/01).

Samples will be shipped to Eurofins located in Altamonte Springs, Florida, and analyzed for CVOCs by United States Environmental Protection Agency (USEPA) Method 8260. In accordance with FDEP guidance, the IDW generated during sampling activities will be containerized on-site and removed for transportation and disposal by a licensed waste hauler (Erwin Remediation Inc.) following receipt of the laboratory analytical report from the second quarterly monitoring event.

Task 3: NAM Field Event Q2

Arcadis will complete an additional monitoring event with the same scope as Task 2.

Task 4: NAM Reporting

A NAM Report will be submitted to the FDEP within 60 days of receipt of the laboratory analytical report from the second quarter of monitoring activities. The Report will contain tables and figures summarizing the results of the two quarterly NAM events and include conclusions and recommendations based upon findings.

Cost Estimate

Arcadis will schedule the field activities following receipt of a TA from the FDEP. The CEF/LOE is included as Attachment 1. The total cost to complete this scope of work is $10,822.52 (Attachment 1). Arcadis proposes the following invoicing schedule:

Completion of NAM field event Q1 $3,163.55 Completion of NAM field event Q2 $3,301.05 NAM Report submittal and PM $4,357.92
