RE: COST PROPOSAL FOR ANNUAL GROUNDWATER MONITORING AND

REVISED RAP MODIFICATION PROPOSAL

DRY CLEANING DEPOT

1320 WEST SUNRISE BOULEVARD

FORT LAUDERDALE, BROWARD COUNTY, FLORIDA

FACILITY IDENTIFICATION NUMBER: ERIC_4158

PROPOSED TASK ASSIGNMENT: HW685_DC026D

Dear Mr. McGrane:

WSP USA Inc. (WSP) is pleased to provide the Florida Department of Environmental Protection (DEP) with this cost proposal to complete annual groundwater monitoring activities and prepare a Remedial Action Plan Modification (RAPMOD) for the above-referenced site. This proposal includes a description of the proposed scope of services, level of effort (LOE) sheets for each subtask, and a Cost Estimate Form (CEF) that summarizes the costs of the proposed services. The proposed scope of services is described below.

RECENT SITE HISTORY

In June 2023, WSP submitted a RAPMOD to the DEP, recommending further enhanced bioremediation injections in the shallow and deep zones in the source area, followed by quarterly groundwater performance monitoring. In addition, WSP recommended a bioaugmentation component such that the Dehalococcoides concentrations can be increased in the shallow and deep surficial aquifer intervals. The goal of the proposed RAPMOD activities was to reduce chlorinated volatile organic compounds (VOC) concentrations in groundwater to levels below the Natural Attenuation Default Concentrations. WSP and the DEP discussed the RAPMOD during the September 6, 2023 site review meeting in Tallahassee, Florida. The DEP requested that WSP complete an updated groundwater monitoring event and revise the RAPMOD since downgradient and upgradient monitoring well data was beyond 270 days. WSP completed the updated groundwater monitoring event in December 2023 and submitted the revised RAPMOD in May 2024. The DEP has requested that WSP complete another groundwater monitoring event, including the collection of samples from the deep injection wells, and update the RAPMOD.

Mr. Patrick McGrane Proposal No. 2025US388880

Florida Department of Environmental Protection April 1, 2025

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 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

WSP proposes to collect groundwater samples from the following 30 wells: MW001R1, MW007, and MW035 in the shallow zone of the surficial aquifer; MW008, MW037, and MW040 in the intermediate zone of the surficial aquifer;

and MW010R, MW011R, MW012R, MW014, MW015R, MW019, MW020, MW022, MW023, MW038, MW039, MW041, MW042, MW043, MW044, MW045, IW-A (80), IW-B (80), IW-C (80), IW-D (80), IW-E (80), IW-F (80), IW-G (80), and IW-K (80) in the deep zone of the surficial aquifer. The attached figures (Figures 2, 3, 7, 8, and 9) from the May 2024 Remedial Action Plan Modification Report, show the monitoring well locations and chlorinated VOC results for the shallow, intermediate, and deep zones of the surficial aquifer. Monitoring wells MW007, MW008, MW014, MW015R, MW022, and MW023 will be used as temporary point of compliance wells. Note: monitoring wells MW014 and MW015R have previously been tasked for sampling; however, WSP has not been able to obtain an updated offsite access agreement. WSP will again attempt to obtain an updated agreement prior to mobilization and in person, if necessary.

Before groundwater sampling, the depth to groundwater will be measured at accessible monitoring well 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). Before 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 accordance with the manufacturer’s recommended procedures.

The groundwater samples will be delivered to a Florida Department of Health and National Environmental Laboratory Accreditation Program certified, fixed-base laboratory for analysis of chlorinated VOCs using EPA Method 8260B. Upon receipt of the laboratory analytical results, WSP will evaluate the constituent concentrations to determine if off-site notification is required.

Investigation Derived Waste WSP will containerize the investigation derived waste (IDW) purge 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 seven drums 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.
