COST PROPOSAL FOR TASK DC012E

<Nu Way Cleaners, Inc./FDEP #ERIC_4701>

< Operations & Maintenance (Eleven Months)> (May 2025 through March 2026)

1. INTRODUCTION: <DISCUSS SCOPE OF WORK, DATES >

GHD submitted a Site Assessment Report/Interim Source Removal Plan (SAR/ISRP) for the Nu-Way Cleaners, Inc. site located in Plant City, Hillsborough County, in July 2015. The SAR/ISRP was approved and the soil vapor extraction (SVE) system was installed in April 2016. Startup of the SVE system occurred on May 20, 2016. Although the system has likely removed the majority of available mass in the vadose zone, additional operations are recommended as part of the recently approved RAP in order to mitigate and potential vapors generated during enhanced groundwater bioremediation.

Task DC012E includes eleven (11) additional months of operation of the SVE system (April 2025 through March 2026) and annual groundwater monitoring. O&M will include monthly site visits and quarterly air sampling. During monthly O&M site visits, the remedial system operation will be verified and performance monitoring will be conducted. Performance monitoring will include determining and adjusting operating conditions to maximize mass recovery.

Subtask 1: Project Management Subtask 1 includes all tasks associated with management of eleven (11) months of O&M, sampling, and reporting at the Nu-Way Cleaner site.

Subtask 2: O&M (May 2025 through September 2025) During the operational period, GHD will conduct monthly Operations and Maintenance (O&M) site visits. During monthly site visits, the SVE system operations will be verified. The system operational conditions will be recorded. These conditions include the current status of each SVE well (open/closed), vacuum readings at wellheads, flow readings (total and well), hour meter readings, and water accumulation. During monthly site visits, the SVE operations will be modified (as directed by the Engineer) in order to optimize mass recovery. Verification of radius of influence may also be conducted. During quarterly site visits, field screening measurements will be recorded for each SVE well. Sampling will be conducted at effluent ports for laboratory analysis. All vapor samples will be analyzed for the presence of volatile organics by Method TO-15 and air phase hydrocarbons by MADEP APH Method.

After six months of operation and receipt of analytical data, an email summary will be prepared including recommendations for additional operations and/or modifications. The email summary will include update remedial action tables and any additional groundwater sampling information.

Subtask 3: Utilities (May 2025 through September 2025) Subtask 3 includes five (5) months of utility (electrical) service. The utility service was obtained through TECO and GHD will submit invoices for reimbursement.

Subtask 4: O&M (October 2025 through March 2026) During the operational period, GHD will conduct monthly Operations and Maintenance (O&M) site visits. During monthly site visits, the SVE system operations will be verified. The system operational conditions will be recorded. These conditions include the current status of each SVE well (open/closed), vacuum readings at wellheads, flow readings (total and well), hour meter readings, and water accumulation. During monthly site visits, the SVE operations will be modified (as directed by the Engineer) in order to optimize mass recovery. Verification of radius of influence may also be conducted. During quarterly site visits, field screening measurements will be recorded for each SVE well. Sampling will be conducted at effluent ports for laboratory analysis. All vapor samples will be analyzed for the presence of volatile organics by Method TO-15 and air phase hydrocarbons by MADEP APH Method.

After the 11th month of operation and receipt of analytical data, a Remedial Action Status Report (RASR) will be prepared including recommendations for additional operations and/or modifications. The RASR will include updated remedial action summary tables and will also summarize any additional groundwater sampling results obtained as part of the RAP implementation.

Annual groundwater performance monitoring is proposed for January 2025. Groundwater sampling will be conducted at twenty-nine (29) monitor wells including: MW001, MW002, MW004, MW006, MW017, MW042, MW029, MW031, MW032, MW033, MW034, MW045, MW047, MW007, MW016, MW019, MW024, MW025, MW028, MW035, MW038, MW040, MW044, MW009, MW014, MW015, MW008, MW022, and MW037. A full round of water levels will be gathered during this sampling event. Samples will be analyzed for the presence of volatile organic halocarbons, total organic carbon, total dissolved solids, total recoverable petroleum hydrocarbons, sodium, ammonia, nitrate, molybdenum, chloride, sulfate, iron, and/or dissolved gases per the RAP sampling schedule.

Subtask 5: Utilities (October 2025 through March 2026) Subtask 5 includes six (6) months of utility (electrical) service. The utility service was obtained through TECO and GHD will submit invoices for reimbursement.

Craig, Is it possible to provide a generic quote for IDW water disposal.

Assumption is non-haz with necessary analytical Maybe provide a range of locations

South florida or central florida, or both?

Thanks in advance

We have many sites that we generate 1 gw drum of IDW and would like to streamline the vendor coordination
