Task Assignment HW687

Terracon Proposal No. PH1227131

Dear Mr. Cox:

Terracon Consultants, Inc. (Terracon) appreciates the opportunity to submit this proposal to the

Florida Department of Environmental Program (FDEP) Waste Cleanup Program (WCP) to conduct

Annual Groundwater Monitoring and Reporting for the Celebrity Cleaners (ERIC_5485) facility located at 190 State Road 427, Longwood, Seminole County, Florida.

Scope of Services

◼ Initial site visit to meet with owner/tenant, evaluate monitoring wells and general site conditions;

◼ Field preparation, prepare health and safety plan, mobilize to site, perform groundwater sampling and laboratory analysis of

VOHs for eight (8) existing monitoring wells (MW011, MW014, MW024, MW025, MW027, MW030R, MW032, and Interior MW), and dissolved gasses for three (3) monitoring wells (MW014, MW024 and MW030R);

◼ Review data and prepare an Annual Groundwater Monitoring

Report including development of a conceptual site model, receptor update, updated tables and groundwater flow and concentration exhibits. See attached LOE for details

Schedule

Submit Annual Monitoring Report within 20 business days following receipt of laboratory results.

Compensation

See attached CEF for details.

Proposal for Annual Monitoring and Preparation of Report

Celebrity Cleaners, ERIC_5485 ■ Longwood, FL

September 24, 2022 ■ Terracon Proposal No. PH1227131

SITE RECOMMENDATIONS

The site was an active PCE drycleaner from 1986 until May 2020 when the operator abandoned the storefront. Historically, the following remedial actions have been implemented at Celebrity Cleaners:

• August 31, 2007 to October 16, 2013: Tetra Tech designed, installed and operated a soil vapor extraction system at the site.

• March 17 – April 9, 2009: Tetra Tech conducted an in-situ chemical injection event using a sodium percarbonate complex (Regenisis RegenOx®).

• April 28-May 28, 2009: Tetra Tech conducted a second in-situ chemical injection event, also using

RegenOX®.

• August 7-9, 2012: Tetra Tech conducted an in-situ biostimulation injection event utilizing 3D microemulsion (3DME).

• August 26 - 29 2014: Tetra Tech conducted a second biostimulation/bioaugmentation event utilizing 3DME and BDI plus.

Although the remedial actions produced reductions in contaminated surficial groundwater, most notably on the periphery of the plume, concentrations in the source area wells (i.e., MW014, MW024, and MW030R) rebounded.

Tetra Tech submitted an Annual Groundwater Monitoring Report documenting groundwater monitoring conducted in August 2020. Six groundwater samples out of the eight collected during the 2020 annual groundwater sampling event exceeded the Chapter 62-777, Florida Administrative Code (FAC)

Groundwater Cleanup Target Levels (GCTLS) and/or Chapter 62-777, FAC Natural Attenuation Default

Concentrations (NADCs) for one or more of the drycleaning constituents of concern (COIs). The data suggests that contamination is highest at 49 feet to 85 feet below land surface (BLS) with source area wells MW014, MW024, and MW030R screened at that interval. Additionally, groundwater samples collected from downgradient wells MW027 and MW032 (screened at 45 to 55 feet BLS) reported COI at concentrations exceeding the respective GCTLs indicating that the plume has not been adequately defined. Dissolved methane was detected in exterior monitoring wells MW014 (9.41 milligrams per liter (mg/L)), MW024 (4.18 mg/l), and MW030R (12.3 mg/L).

The annual groundwater monitoring data indicates a generally decreasing, although fluctuating, trend of COIs and suggests that the biostimulation and bioaugmentation injection events have been successful in stimulating source area bioremediation activity. Due to the duration of over two years since the last sampling event, and over 8 years since the biostimulation/bioaugmentation event, coupled with a fluctuating trend in concentrations, Terracon recommends sampling 7 monitoring wells for VOHs, as summarized in the following table. Additionally, Terracon recommends collecting samples for analysis of dissolved gasses from MW014, MW024 and MW030R. An evaluation of current groundwater quality data from these wells will provide a clearer and more comprehensive strategy for a path forward.
