Contract No. HW687 Proposed Task Assignment No. DC028F Terracon Proposal No. PEQ257451/EQ237242D

Dear Mr. Sostre:

Terracon Consultants, Inc. (Terracon) appreciates the opportunity to submit this proposal to the Florida Department of Environmental Program (FDEP) Waste Cleanup Program to conduct Annual Groundwater Monitoring (GWM) activities and prepare a report documenting the results for the former Alpine Cleaners facility (Site), located at the intersection of 5240 NW 34th Boulevard, Suite E, in Gainesville, Alachua County, Florida.

The purpose of this proposal is to collect groundwater samples from five shallow zone monitoring wells for analysis of volatile organic halogens (VOHs) constituents of concern as identified in the recommendations section of the Supplemental Site Assessment Report, dated February 14, 2025 and prior to system startup of the Soil Vapor Extraction system. In addition, no groundwater samples are proposed to be collected for analysis of per- and polyfluoroalkyl substances (PFAS) constituents of concern since the previous PFAS results at concentrations below the Practical Groundwater Cleanup Target Levels (PGCTL) during the last two sampling events.

Proposal for Annul Groundwater Monitoring and Report Alpine Cleaners, ERIC_3987 ■ Gainesville, FL January 29, 2026 ■ Terracon Proposal No. PEQ257451

Scope of Services

Project management Preparation of updated Health and Safety Plan (HASP) Verify property ownership (both source and offsite) and notify the property owners/tenants and offsite property owners of scheduled field activities Depth to water measurements from 8 monitoring/piezometer wells Annual groundwater sampling to include VOH constituents of concern from five shallow zone monitoring wells (Exhibit 5) Investigative derived waste (IDW) management and disposal Preparation of a GWM report documenting the findings with conclusions and recommendations

See attached LOE (Attachment A)

Schedule

Deliverable of field notes, groundwater sample logs, and chain-of-custody documentation, within 5 to 7 business days of completion of subtask field work Deliverable of GWM report within 30 business days following receipt of laboratory results.

Compensation See attached CEF for details. (Attachment A)

SCOPE OF SERVICES

Subtask 1 – Project Management

Ralph F. Mongillo Jr P.G. will serve as the Project Manager during the field investigation.

Donna Cline, P.E., will be involved throughout the project, serving as Authorized Project Reviewer.

Terracon obtained quotes from subcontractors for IDW management services. Exhibits of proposed sample locations are provided in Attachment B. A summary of subcontractor quotes and selected contractor is provided for each service in Attachment C and includes a copy of the quotes.

Subtask 2 – Groundwater Monitoring

Pre-Task Planning will be performed to prepare for field investigations. Terracon will update the existing site-specific health and safety plan. Terracon will also pick up the IDW drum, order the sample kits, and meet internally to discuss the scope of work, and the sampling equipment required.

Site Access Verifications and Notifications Verify that the source and off-site property owners that signed the FDEP Permission to Enter Property form still own the properties. Terracon will also notify the source property owner South Financial Services Inc. (Land Parcel No. 06083-025-000), and the tenant, and non-source offsite property owner J & Z Properties Inc. (Land Parcel Nos. 06083-026-002 and 06083-026-003) of the schedule for the field work.

Groundwater Well Sampling Groundwater samples will be collected from five (5) shallow zone wells (MW001S, MW002S, MW004S, MW005S, and PZ003) for VOH analysis (Exhibit 5). The monitoring wells will be sampled in accordance with the FDEP SOPs, dated January 2017 (effective April 16, 2018) for chlorinated solvents. Prior to monitoring well sampling activities, Terracon will collect depth-to-water measurements of the five shallow zone monitoring wells to be sampled and MW003S, PZ001, and PZ002.

Terracon will complete an email deliverable for Subtask 2 documenting the field event is completed by providing field notes, groundwater sampling forms, laboratory chain-of-custodies, and nonhazardous waste manifest.

Terracon will prepare an Annual Groundwater Monitoring (GWM) report that includes a summary of the sampling methodology and analytical results. The GWM report will include tables and figures summarizing the groundwater results in comparison to FDEP’s Cleanup Target Levels (groundwater). Exhibits will be provided to illustrate the site layout, sample locations, and results by matrix.

IDW Management and Disposal Liquid IDW derived from purge water during the Subtask 2 will be contained in one DOT approved 55-gallon drum and temporarily stored onsite until the waste characterization sample results for the full list VOCs can be evaluated. Assuming the waste is non-hazardous, the drum will be transported to an approved facility for disposal or treatment.

Estimate one (1) drum of liquid.
