DC010B Completion December 31, 2022

This TA authorizes costs for review & evaluation of existing soil and SVE operations data, and other existing data, and submittal of a data evaluation report, based on the Terracon proposal letter dated 7/22/22 and cost estimate dated 9/1/22. The total cost for this TA is $7156.97 and all costs are fixed unit rate. The data evaluation report deliverable will inform development of a soil assessment workplan considering the likely remedial remedy of soil excavation & SVE. This workplan will be authorized in a subsequent TA.

TO: HW687 Contract File FROM: Dean Cox, Contract Manager SUBJECT: DC010B: Soil Sampling Workplan (Best ERIC_5517)

DATE: 9/13/2022

This TA authorizes costs for review & evaluation of existing soil and SVE operations data, and other existing data, and submittal of a data evaluation report, based on the Terracon proposal letter dated 7/ 22/ 22 and cost estimate dated 9/ 1/ 22. The total cost for this TA is $7156.97 and all costs are fixed unit rate. The data evaluation report deliverable will inform development of a soil assessment workplan that considers the likely remedial remedy of soil excavation & SVE.

This workplan will be authorized in a subsequent TA.

The deliverable will include data research, development of soil contaminant contours (PCE, TCE, TRPH) at various depth intervals, lithologic cross sections with soil analytical results, a three-dimensional model of the soil source zones, source zone evaluation for potential limits of LDA excavation, SVE well ROI calculation evaluation & effectiveness, and other evaluation & discussion as indicated in the Terracon proposal letter dated 7/ 22/ 22. The site access agreement was confirmed accurate and current.

Terracon initially submitted an informal written proposal for a soil assessment workplan including figures they created and information on the City of Deland development plan. The FDEP PE questioned the depth of the soil sampling and the relative lack of locations near and under the former drycleaner’s foundation. A meeting was then held with Terracon, with the FDEP PE, PG and PM in attendance. Terracon initially considered using MIP in assessment, but the PG discouraged that and had concerns regarding the density of the soil sampling locations.

Terracon submitted another figure with new soil sampling locations & depths, but after additional discussion with FDEP, Terracon decided to request this TA for additional data review & evaluation. The PE wanted to review this TA proposal and did. After his review and internal discussion with the other WSCS PE, he was more supportive of the LDA approach and soil sample location densities. The PG indicated he would defer to the PE. Considering the site clay layers, perched water table, the relatively large area of contaminated soil, and the poor remedial progress of the previous contractor, the information produced by this TA is valuable for implementation of the most efficient site cleanup.

Using GIS and/or CAD, formalize lithological cross sections, soil contour drawings for each COI (4 cross sections, and 20 contours per COI)

Evaluate if a camera investigation of sanitary sewer was performed, and if performed evaluate the results as it relates to the known soil contamination (i.e. identify the conceptual site model)

Prepare draft maps of soil contaminant contours for each COI at various depth intervals from land surface to the depth of groundwater, estimate 24 contours

Evaluate the above information and data presentation, and provide a soil sampling workplan that provides source zone evaluation and horizontal and vertical delineation of the soil contamination to satisfy Rule 62-780, F.A.C.

Evaluate previous reports and gather hisotrical soil data and soil boring logs Using exisiting soil boring logs, draft 4 lithological cross sections Overlay soil laboratory analytical results on the lithological cross sections for each of the COIs

Evaluate the historic SVE systems, and estimated ROI with respect to existing soil contamination to address the question whether the SVE systems were effective, and identify limiting factors

Prepare a three dimensional model using soil locations, lithological profiles and soil contaminant concentrations
