Leesburg, Lake County FROM: Theresa Pepe, Project Manager SUBJECT: Task Assignment DC013D (HW680) DATE: September 14, 2023

Arcadis U.S. Inc. will perform annual groundwater monitoring from select wells at the site. A comprehensive groundwater monitoring event will help determine if additional bioremediation injections are needed. All activities will be conducted in accordance with the September 8, 2023, Work Plan submitted by Chad Hanna of Arcadis.

The final task assignment total is $20,423.02. 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 An access agreement with the real property owner was obtained on December 17, 2021.

No changes in ownership have occurred since that date.

This subtask provides costs for sampling twenty-nine on and off-site wells plus one IDW sample. In addition to drycleaning solvents, background UIC parameters will be sampled at some wells per request of FDEP’s engineer. Passive Diffusion Bags (PDBs) will be utilized in some wells as a cost-saving measure. The original proposed rate for PBDs was increased according to the approved HW680 contract.

IDW will be disposed of by EnviroServe – formerly Clark Environmental.

Subtask 3: Reporting

Arcadis will submit an annual monitoring report as the final deliverable. This subtask provides costs for tabulating data, drafting updated figures and considering remedial strategy based on the groundwater sampling results.

Hours and costs are comparable to past task assignments of similar scope.

Subject: Groundwater Monitoring Event Proposal

Donna’s Cleaners

1421 W Main Street

Leesburg, Florida

FDEP Facility ID: ERIC_4824

Dear Ms. Pepe, Arcadis U.S., Inc. (Arcadis) is pleased to submit to the Florida Department of Environmental Protection (FDEP) this proposal to sample select monitor wells at the Donna’s Cleaners Site, located at 1421 West Main Street in

Leesburg, Florida (Site). This proposal includes a description of the proposed scope of work, and the associated estimated cost and schedule for their completion.

Scope of Work

The scope of work is comprised of three tasks. The tasks include project management, groundwater monitoring, and reporting. A brief description of each task follows.

Task 1: Project Management

This task consists of project management activities and health and safety efforts in relation to the completion of

Tasks 2 and 3.

Task 2: Groundwater Sampling

The proposed monitoring event will include the collection and analysis of groundwater samples in accordance with the groundwater monitoring plan (Table 1). Water levels will be collected from 47 site-wide monitor wells.

Passive diffusion bag (PDB) samplers were previously installed in selected wells during the 2022 event. To sample these wells, the PDBs will be removed from the wells and groundwater samples will be collected in

Ms. Theresa Pepe

Florida Department of Environmental Protection

September 8, 2023 www.arcadis.com

2023.09 - Donna's Cleaners NAM Proposal

2/2 laboratory-supplied bottles. New PDBs will be installed in the wells after sampling. Ten monitor wells for which

Underground Injection Control (UIC) parameters will be collected will be sampled using the low-flow purge technique.

The groundwater samples will be shipped to Eurofins in Tampa, Florida, and analyzed for chlorinated volatile organic compounds (CVOCs) by United States Environmental Protection Agency (USEPA) Method 8260. UIC parameters include chloride by USEPA Method 300, color by SM 2120B, total dissolved solids by SM 2540C, and pH by SM 4500. The purge water collected during the event will be containerized in a 55-gallon drum for proper off-Site disposal.

Task 3: Reporting

A Groundwater Monitoring Report (GMR) will be submitted to the FDEP within 60 days of receipt of the laboratory analytical report. Consistent with previous submittals, the report will include the analytical data for the sampling event, tables summarizing the groundwater data, contour maps showing the groundwater flow direction for each aquifer zone, and isoconcentration contour figures for major CVOCs. Based on the analytical results, a recommendation for a future course of action will be included in the report.

Cost Estimate

A CEF is attached for the above scope of work. The total cost to complete this scope of work is $20,291.77

(Attachment 1). Arcadis proposes the following invoicing schedule:

Completion of groundwater monitoring field activities $11,918.15

Annual GMR submittal and PM $8,373.62

Closing Remarks Arcadis appreciates the opportunity to assist the FDEP at this site. If you have any questions or wish to discuss this proposal, please do not hesitate to contact us.
