RE: COST PROPOSAL FOR ANNUAL GROUNDWATER MONITORING

CLOTHESHANGER CLEANERS

1818 NORTH MONROE STREET

TALLAHASSEE, LEON COUNTY, FLORIDA

FACILITY IDENTIFICATION NUMBER: ERIC_4874

PROPOSED TASK ASSIGNMENT: DC005C

Dear Mr. McGrane:

WSP USA Inc. (WSP) is pleased to provide the Florida Department of Environmental Protection (DEP) with this cost proposal for annual groundwater monitoring activities at the above-referenced site. This proposal includes a description of the proposed scope of services, level of effort sheets for each subtask, and a cost estimate form that summarizes the costs of the proposed services. The proposed scope of services is described below.

SUBTASK 1 PROJECT MANAGEMENT

To facilitate project quality and satisfactory completion of the proposed scope of work, all aspects of this project will be overseen by an experienced project manager. The project manager will be responsible for the schedule, budget, invoicing, project activities, and communications with the DEP and the field team. Project management will include coordination of field activities; resource allocation to confirm the work is conducted by qualified professionals in accordance with the project schedule; cost control and tracking of the budget status; and submittal of project invoices in accordance with the DEP Waste Site Cleanup Section requirements. The project manager will oversee the work so that it is conducted in a manner that is consistent with the requirements of the DEP-approved task assignment.

SUBTASK 2 ANNUAL GROUNDWATER MONITORING ACTIVITIES

Site Access current property owner and relevant offsite property owners have an executed Permission to Enter Property agreement with the DEP. WSP will then coordinate with the real property owner, tenant, and offsite property owners for access to complete the scope of work. WSP or the DEP will attempt to obtain updated Permission to Enter

Property forms from relevant property owners prior to and/or during mobilization to the site, as needed.

Mr. Patrick McGrane Proposal No. 2025US410485

Florida Department of Environmental Protection May 5, 2025

Groundwater Sampling

WSP will collect groundwater samples from the following 11 monitoring wells: MW004, MW006, MW015, MW017, MW018, MW019, MW058, RW002, RW006, RW008, and RW012. The well locations and previous analytical results are shown on the attached Figures 4 and 5.

Prior to groundwater sampling, the depth-to-groundwater will be measured at accessible monitoring wells using an electronic water level indicator to determine groundwater elevations and flow direction. During the sampling event, the locks and well caps will be inspected for damage or degradation and repaired or replaced as necessary.

Groundwater samples will be collected from the wells in accordance with DEP Standard Operating Procedures

(SOPs) for Field Activities (DEP-SOP-001/01) dated January 2017 (effective April 16, 2018). Prior to collecting the groundwater sample, each well will be purged and field parameters including temperature, pH, specific conductance, dissolved oxygen, turbidity, and oxidation-reduction potential will be monitored. Purge volumes and field parameters will be recorded on field data sheets, and the field monitoring equipment will be calibrated in low-flow sampling methods.

The samples will be placed in laboratory-supplied containers, labeled with a unique identification number attached to the outside of the sample container, and preserved on ice in a laboratory-provided cooler. The groundwater samples will be shipped to a Florida Department of Health and National Environmental Laboratory Accreditation

Program-certified, fixed-base laboratory, along with the completed chain-of-custody, for analysis of chlorinated volatile organic compounds (VOCs) using EPA Method 8260B.

Investigation-Derived Waste

WSP will containerize the investigation-derived waste (IDW) purge water and decontamination water in a 55-gallon drum. WSP will collect a waste characterization sample from the drum for analysis of total VOCs using EPA

Method 8260. The drum will be temporarily staged onsite, pending waste characterization. For cost-estimating purposes, WSP has assumed that the IDW can be transported and disposed of as non-hazardous waste at an approved facility. The IDW transportation and disposal subcontractor will provide WSP with a non-hazardous waste manifest upon delivery to the disposal facility. WSP estimates one drum of IDW purge water will be generated during the field activities.

Interim Deliverable

Upon completion of Subtask 2, an e-mail deliverable will be submitted and include copies of the field data sheets, equipment calibration forms, field notes, laboratory analytical report, laboratory chain-of-custody documentation, and non-hazardous waste manifest.

SUBTASK 3 REPORTING

WSP will prepare an Annual Groundwater Monitoring Report that will include a description of the sampling procedures, evaluation of the analytical results; comparison of current to historical data; tabulated summary of the current and historical analytical data; site maps showing the groundwater analytical results and soil gas analytical results; water level elevation information in tables and figures; laboratory analytical data; and conclusions and recommendations.

HEALTH AND SAFETY

WSP will update the existing site-specific Health and Safety Plan for the field work. The work will be completed in safety vests, and steel-toed boots. A safety job briefing will be conducted prior to the start of work activities, and anytime the scope of work or site conditions change.

COST AND SCHEDULE

The estimated cost to complete the proposed scope of work is $14,358.39. WSP anticipates the monitoring event will take place in May 2025. The level of effort sheets and cost estimate form are included in Attachment A. The subcontractor quotes are included in Attachment B. The following table summarizes the proposed costs and deliverable schedule.

Task Proposed Cost Proposed Schedule/Deliverables

Subtask 1 Project Management $ 1,339.67 November 7, 2025

Subtask 2 Annual Groundwater Monitoring Activities

$ 8,649.39 August 8, 2025 (Field Documentation, Laboratory Report, and IDW Manifest via e-mail deliverable)

Subtask 3 Reporting $ 4,369.33 October 3, 2025 (Annual Groundwater Monitoring Report)

Total/Completion Date $ 14,358.39 December 5, 2025

WSP appreciates the opportunity to provide services to the DEP. Should you require additional information or clarifications, please contact us at (904) 363-3430.
