FACID NO. 17-9700554; ERIC_4657

Pensacola, Escambia County FROM: Theresa Pepe, Project Manager SUBJECT: Task Assignment DC018B (HW680) DATE: February 14, 2024

Arcadis U.S. Inc. will perform annual groundwater monitoring from select wells at the site. Groundwater monitoring will ensure that natural attenuation of contaminants continues to occur. All activities will be conducted in accordance with the February 14, 2024, Work Plan submitted by Mike O’Sullivan of Arcadis.

The final task assignment total is $16,114.80. Arcadis may invoice according to the attached schedule.

Specific negotiated subtasks are as follows:

Subtask 1: Project Management Project Management is automatically calculated as a percentage of total labor.

Subtask 2: Annual Groundwater Monitoring FDEP obtained site access from the new property owner in January 2024. Arcadis will confirm access with source and non-source properties prior to fieldwork.

Arcadis will sample twenty-one wells for drycleaning solvents based on recommendations from the previous monitoring report. Passive Diffusion Bags (PDB’s) will be utilized for the sampling. Note: The plume is large, at multiple lithologic depths, and is migrating toward a public well. Therefore, the high number of wells sampled is justified.

During task negotiations, one hour was deleted from the Principal Scientist; it was considered project management under the approved contract.

Mariner Mall, ERIC_4657

Subtask 3: Reporting An Annual Monitoring Report including recommendations for additional actions will be provided under this subtask. Hours and costs are comparable to past task assignments of similar scope.

Ms. Theresa Pepe Bureau of Waste Cleanup Division of Waste Management Florida Department of Environmental Protection 2600 Blair Stone Road, M.S. 4520 Tallahassee, Florida 32399-2400

Date: February 1, 2024 Subject: Proposal for Annual Groundwater Monitoring at Mariner Mall (formerly Big B Cleaners), 4335 Fairfield Drive, Pensacola, FL, FDEP Facility Identification Number ERIC_4657.

Dear Ms. Pepe, Arcadis U.S., Inc. (Arcadis) is pleased to submit this level of effort (LOE) and cost proposal for the annual groundwater monitoring activities at Mariner Mall (formerly Big B Cleaners), located at 4335 Fairfield Drive, Pensacola, FL (FDEP Facility Identification Number ERIC_4657; “the Site”). This proposal includes one groundwater monitoring event, and one letter report summarizing field activities. The FDEP cost estimating spreadsheets (Attachment A) is attached.

SCOPE OF WORK

Subtask 1 - Project Management Subtask 1 is reserved for project management as specified by FDEP and is calculated automatically in the cost estimating form (Attachment A).

Subtask 2 - Groundwater Monitoring (2024) Depth-to-water (DTW) will be measured in 21 existing monitor wells. DTW measurements will be used to establish groundwater flow direction, horizontal gradients, and vertical gradients. Following completion of DTW measurement, PDBs will be removed from 21 existing wells (MW002, MW003, MW010, MW011, MW012, MW013, MW014, MW015, MW016, CW008, MW006, MW007, MW018, MW019, MW020, MW021, CW012, MW023, MW024, MW025, and MW026). Each PDB or monitor well will be sampled for volatile organic halocarbons (VOHs only) by EPA Method 8260C for a total of 21 groundwater samples. Groundwater samples will be delivered to a National Environmental Laboratory Accreditation Program (NELAP)-approved laboratory for analysis. Due to the volume contained in each PDB and that the field water quality parameters are not reflective of true aquifer conditions, field water quality measurements will not be collected. Monitoring well purge water will be contained in 55-gallon drums, sampled for characterization, and disposed of properly. Monitoring well locations are shown on attached figures.

FDEP – Mariner Mall Proposal 2024 www.arcadis.com _Mariner Mall AGM proposal_feb24

PDB Replacement PDBs will be replaced in the 21 monitor wells sampled for use during the next annual monitoring event. Field replacement of PDBs during the sampling event will allow the PDBs to achieve equilibrium with aquifer at an earlier date and is cost saving measure for future groundwater monitoring events. The Interstate Technology Regulatory Council (ITRC) PDB Samplers Frequently Asked Questions states that PDBs have been used to annually monitor groundwater sites with no obvious loss of bag integrity depending on groundwater conditions.

Subtask 3 - Annual Groundwater Monitor Report (2024) Upon completion of sampling activities and receipt of laboratory analytical reports, Arcadis will prepare an Annual Groundwater Monitoring Report. The report will detail sampling activities and present updated tables and figures depicting groundwater flow direction and plume extent/concentrations. The report will present conclusions and recommendations based upon historical and newly acquired data.

SCHEDULE

Arrangements for groundwater sampling activities will be conducted upon receipt of a Task Assignment (TA) from the FDEP.

ESTIMATED COST

A Cost Estimate Form and Level of Effort forms (CEF/LOE) that present estimated project costs are included as Attachment A. Please contact me if you have any questions regarding this proposal.

Re: Drum Disposal – 4335 Fairfield Drive – Pensacola, FL

Mr. O’Sullivan:

Please ensure that all drum lids are properly secured and that drums are on a level surface like the surrounding area (i.e., not on a pallet, etc.). A single False Mobilization fee will apply if our driver is not able to locate a drum on site or if we are unable to access the property due to a locked gate, etc.

This quote is valid for 90 days.

The price for transportation and disposal of two (2) drums of non-hazardous groundwater impacted with drycleaning solvents from your site in Pensacola, Fl will be $95.00 per drum, or $190.00 total.
