Proposed Scope of Work Altamonte Springs Dry Cleaners Biennial Groundwater Sampling Proposal Task Assignment DC(TBD)A ERIC_5459 (Former FAC ID No. 599500541) APTIM Environmental & Infrastructure, LLC (APTIM) 12/8/25

The following proposed scope of work for the former Altamonte Springs Dry Cleaners is to perform biennial groundwater sampling. This scope of work includes the collection of groundwater samples from four monitoring wells for analysis by EPA Method 8260 for volatile organic halocarbons (VOHs) as recommended in the previous Biennial Groundwater Monitoring Report dated November 9, 2023. No PFAS sampling is proposed as previous sampling results for these constituents reported no exceedances of the PGCTLs, and a Publix Supermarket is the plaza�s anchor store.

Subtask - 1: Project Management This task includes project management activities associated with the completion of

Tasks 2 through 5, as calculated in accordance with Contract HW689.

Subtask - 2: Monitoring Well Sampling APTIM proposes groundwater samples be collected from four monitoring wells. Prior to groundwater sample collection, depth to water measurement will be collected from all wells that can be located and accessed. Groundwater samples from monitoring wells

MW009, MW017 and MW019 will be collected from the deployed Passive Diffusion Bags (PDBs). In addition, a groundwater sample will be collected from deep monitoring well

MW013 using conventional sampling techniques. The groundwater sample from MW013 will be collected in accordance with the FDEP Standard Operating Procedures for Field

Activities utilizing a submersible pump and a field-calibrated YSI multi-parameter instrument.

The purge and decon water from sampling activities will be placed in a DOT approved drum, characterized by the collection of an IDW sample for VOHs only (EPA Method

8260), and stored onsite for future transport and disposal. APTIM recommends Erwin Remediation to perform the IDW transportation and disposal based on three bids received. Note that although PFAS constituents were not reported above the PGCTLs in groundwater at the site, PFAS was detected, therefore the disposal rate is increased.

Please see the attached IDW bid summary documents.

Three replacement PDBs will be obtained from ALS Environmental (ALS), a licensed manufacturer of passive diffusion samplers. The PDBs will be assembled and placed within each well similar to the previous PDB sampler placement. Each PDB sampler is 24� long and 1 ¼� in diameter and pre-filled with approximately 220 milliliters of certified, laboratory-grade, analyte-free, deionized water. Specific deployment of the PDB bags is as follows.

1. MW009, (2� well) total depth of approx. 84 ft bls (placement from 80.5 to 82.5 ft bls)

2. MW017, (2� well) total depth of approx. 85.5 ft bls (placement from 82 to 84 ft bls)

3. MW019, (2� well) total depth of approx. 85.5 ft bls (placement from 82 to 84 ft bls)

Subtask - 3: Biennial Groundwater Reporting At the conclusion of the groundwater sampling event and upon receipt of the analytical report from the fixed laboratory, a Biennial Groundwater Monitoring Report documenting the sampling and results will be prepared and include conclusions and recommendations for future site activities.

APTIM recommends the following schedule:

Description Due Date

Perform VOH Sampling 2/27/26

Submit Biennial Groundwater Monitoring Report 3/27/26

Task expiration date 4/30/26

APTIM proposes to perform this scope of work in accordance with the terms and conditions of the DEP Contract No. HW689 between the Florida Department of Environmental Protection and APTIM dated December 21, 2021. APTIM will begin the proposed scope of work upon issuance of the Task Assignment Notification. This site has an Access Agreement dated October 2004 providing approved for the proposed scope of work.

If you have any questions, please contact us for clarification.

RE: IDW Drum Transportation & Disposal North, Central, West Coast, East Coast, & South Florida Lewis Proposal No. 40908LA

Dear Mr. Kramer, Lewis Environmental, LLC (Lewis) is pleased to offer APTIM Orlando (APTIM) this proposal to provide waste transportation and disposal services across the state of Florida. This proposal is based on the information provided by the client and from performing similar work throughout the Southeast region. The following is offered for your review and consideration:

Scope of Work:

1. Prior to mobilization, Lewis will prepare waste profiles for review and signature by the authorized agent for generator. Lewis will then submit signed profiles to the designated disposal facilities for final review and approval.

2. Upon disposal facility approval and scheduling of the waste removal event with the client.

Lewis will mobilize the following crew and equipment: one driver, one rack truck, and any accessories required for this scope of work.

3. Lewis will inspect and label all proposed waste materials onsite for DOT Compliance.

4. Lewis will load all permitted waste streams onto the rack truck for offsite shipment.

5. At shipment time, Lewis will provide waste manifests for review and signature by an onsite agent for the generator.

6. Lewis will then transport the waste drums to the designated licensed facilities for disposal.

7. Upon receipt from the facilities, Lewis will provide APTIM with the final copies of all waste disposal documentation.

Pricing Schedule:

Description of Services Cost Transportation for the North Zone $1,285.00 / Trip Transportation for the Central Zone $860.00 / Trip Transportation for the West Zone $819.00 / Trip Transportation for the East Zone $1,040.00 / Trip Transportation for the South Zone $1,433.00 / Trip Profile for New Sites, Non-PFAS $100.00 / Each 55 Gallon Drum Disposal Non-PFAS $123.00 / Drum Profile for New Sites, PFAS Impacted $150.00 / Each 55 Gallon Drum Disposal PFAS Impacted $475.00 / Drum

Lewis understands client will have all proposed waste containers DOT compliant prior to

Lewis mobilization to the site. This includes non-leaking or non-bulging, lids, bungs and rings in place and fastened, and no holes or major dents. If any of the containers are not DOT shippable, Lewis will provide the missing items or overpack the drummed waste into 85-gallon overpack steel containers at an additional cost.

Clear and adequate access to the site will be available on scheduled workdays, Lewis assumes access within 50 feet of the work area, including adequate parking for company vehicles.

Lewis assumes all surface debris/obstructions will be removed from the work area prior to arrival. Failure to do so may cause delays in work and additional expenses.

Lewis assumes sanitary facilities will be made available to Lewis personnel.

The cost to perform sampling and analytical testing is not included in this proposal.

Lewis assumes that the customer will provide the Florida Department of Environmental

Protection hazardous waste site number, known as an EPA ID number for profiling and manifesting of the PFAS impacted waste.

Lewis assumes that all activities involving completion of the scope of work can be performed in level D Personal protective equipment (PPE).

The cost and terms of this proposal are valid for no more than a one-year period. Lewis reserves the right to adjust pricing based on fluctuating disposal costs.

Lewis assumes that any project delays resulting due to unforeseen site conditions or the above assumptions/clarifications will be billed at Lewis time and material rates.

Lewis appreciates the opportunity to provide you with a cost estimate for the work described above. If you have any questions regarding our proposal at any time, please feel free to contact the undersigned at your convenience. Thank you for your consideration.

Sincerely,
