Waste Cleanup Contract No. HW687

Terracon Proposal No. PH4247021

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 to conduct groundwater monitoring for VOHs, and to perform expanded groundwater sampling for per-and polyfluorinated substances (PFAS) analysis, and Reporting for Carriage Trade Dry Cleaners (ERIC_4799) facility located at 3920, 3924, and 3944 West Hillsborough Avenue Tampa, Hillsborough County, Florida.

Scope of Services

◼ Field preparation, update health and safety plan for combined

PFAS and VOH groundwater sampling;

◼ Mobilize to site, perform groundwater sampling of four (4) monitoring wells and four (4) piezometers, MW001S, MW002I, MW003S, MW003I, PZ001, PZ002, PZ003, and PZ004 for VOH analysis;

◼ Include PFAS analysis in the collected groundwater samples

◼ Collect water levels from four (4) monitoring wells and four (4) piezometers, MW001S, MW002I, MW003S, MW003I, PZ001, PZ002, PZ003, and PZ004;

◼ Submit PFAS samples in cooler preserved on ice by overnight courier to FDEP’s laboratory for sample analysis;

◼ Review data and prepare a Groundwater Monitoring Report including updated tables, groundwater flow, and concentration exhibits;

◼ PFAS sampling data will be included as a section in the groundwater monitoring report to include an exhibit, certified lab report, field notes and forms, and a summary of the QA/QC and mailto:Dean.Cox@FloridaDep.gov

Proposal for Combined VOH and PFAS Groundwater Sampling and Reporting

Carriage Trade Dry Cleaners, ERIC_4799 ■ Tampa, FL

(showing PFOA, PFOS, and PFOA+PFOS concentration for each well)

See attached LOE for details

Schedule Deliverable Annual Groundwater Monitoring Report submitted within 20 business days following receipt of laboratory results.

Compensation

See attached CEF for details.

SITE RECOMMENDATIONS

Terracon performed Site Assessment Activities in January and February 2023. Based on the results of the 2023 Assessment, concentrations of 1,1-dichloroethene (DCE) were reported above its respective groundwater cleanup target level (GCTL) outlined in Chapter 62-777, Florida Administrative Code

(F.A.C.).

Concentrations of 1,1-DCE were reported above the GCTL of 7 micrograms per liter (µg/L) in MW002I

(14 µg/L). No other detections of 1,1-DCE were reported from the monitoring wells (and piezometers) at the Site. 1,1-dichloroethane (DCA) was detected in MW002I (4.1 µg/L) below its respective GCTL of

70 µg/L.

Other volatile organic halocarbons (VOHs), including cis-1,2-DCE and trans-1,2-DCE, were also detected at PZ004 (58 µg/L and 1.1 µg/L, respectively) below their respective GCTLs (70 µg/L and

100 µg/L, respectively).

Based on this data, Terracon recommends VOHs sampling of the existing monitoring wells to confirm the previously reported VOHs concentrations and evaluate any potential trends of VOH concentrations.

Terracon also performed per-and poly-fluoroalkyl substances (PFAS) sampling activities during the

February 2023 sampling event. PFOA, PFOS, and their combined sum were reported in MW001S, MW003S, PZ001, PZ002, and PZ004, above the provisional groundwater cleanup target level(s) of 70 ng/L. Based on this data, Terracon recommends PFAS sampling of the existing monitoring wells to confirm and evaluate any potential trends of PFAS at the Site.

DELIVERABLES

The Groundwater Monitoring Report will detail and summarize the groundwater sampling activities, field observations, and results of monitoring well analysis and will include updates to the site’s historical data tables and updated exhibits of groundwater flow and well concentrations. Conclusions and recommendations will include a summary of results and recommendations for future sampling, closure, or remedial activities. As mentioned earlier the PFAS evaluation will be provided in an additional section within this report.
