This Task Assignment authorizes Geosyntec to conduct site assessment activities at Pelican Dry Cleaners in accordance with the Geosyntec scope of work, cost estimate, and schedule received on June 19, 2023.

Geosyntec confirmed on June 21, 2023, that Subtask 1 consists of the calculated project management labor, based upon 13% of the direct labor costs in this proposal, and includes fringe, overhead, other direct costs (ODCs) and completion fees.

Subtask 2: This subtask includes cost for the first phase of site assessment activities, which includes a private underground utility survey, one lithology boring (SB003), soil sampling (SB001-SB007, MAGS001-MAGS005), up to 12 locations proposed locations (36 samples total), 5 MAGS well installation (MAGS001-MAGS005) and sampling, one vapor monitoring point (VMP001) will be installed, direct push technology (DPT) groundwater sampling at about 8 locations (DPT001-DPT008), and interior monitoring well installation (MW001).

These data will be provided to FDEP for evaluation to select the locations of proposed monitoring wells to be installed in Subtask 3.

Subtask 3: Once the final monitoring well strategy has been established with FDEP, Geosyntec will re-mobilize to the Site to install and sample the monitoring wells. Geosyntec personnel will observe the installation of up to 4 exterior monitoring wells to evaluate groundwater quality.

Additional water-table monitoring wells will be installed up gradient, side gradient, and down gradient of the facility using the DPT drilling method, while one well will be a vertical extent well depending on SB003 data.

This subtask includes costs for a Florida professional land surveyor to survey the newly installed monitoring wells. Geosyntec will also collect groundwater samples from the site monitoring wells which will be analyzed for VOCs. Subtask 3 activities will be performed by 1 Geosyntec staff member assuming 2 days for drilling oversight.

Printed on recycled paper.

Dear Ms. Plyler, Geosyntec Consultants, Inc. (Geosyntec) has prepared this Scope of Work and Level of Effort (LOE) for site assessment activities at the Pelican Dry Cleaners site (Site) located in Clearwater, Florida (ERIC_5292). Geosyntec prepared this LOE based on Geosyntec’s 28 April 2023 Site Assessment Work Plan (SAWP), approved by FDEP. A description of task breakdown for Site assessment field activities and report preparation is provided below.

SUBCONTRACTOR EVALUATION

Geosyntec obtained three bids from licensed and qualified utility locating, drilling, and IDW transportation and disposal firms; a cost comparison is provided in Attachment A. The drilling work was bid as a single project with two mobilizations so that the total price was used in the evaluation. Geosyntec recommends the following subcontractors based on lowest cost among the qualified bidders:

• Underground utility locating – GeoTek

• Soil sampling, MAGS installation, DPT groundwater sampling, and MW installation – Preferred Drilling Solutions (PDS) (6.5 total field days)

• IDW transportation and disposal – Erwin Remediation

SurvTech Solutions, Inc. is recommended for surveying the five (5) monitoring wells. Copies of the bids from each subcontractor are included in Attachment A.

For ease of reference, Table 1 and Figures from the SAWP are attached as a summary of the field activities and samples to be collected.

Ms. Brittany Plyer 19 June 2023

Subtask 1 – Project Management

Fabio Fortes (Tampa Bay) will be the Geosyntec Project Manager. His labor hours are directly computed.

Subtask 2 – Multi-Media Sampling (Soil, DPT groundwater, soil vapor) and Interior Monitoring Well Installation

Subtask 2 includes labor for field preparation, completion of one offsite access agreement needed for the Site Assessment, and preparation of a Site Health and Safety Plan. Geosyntec personnel will mobilize to the Site to observe the first phase of site assessment activities, which includes a private underground utility survey, lithology boring, soil sampling, MAGS well installation and sampling, direct push technology (DPT) groundwater sampling, and interior monitoring well installation.

Utility locating: Geosyntec will observe utility locating at the Site performed by GeoTek.

Identified utilities will be mapped by Geosyntec staff using a Global Position System (GPS) unit following the private underground utility survey.

Lithology boring: One soil boring (at SB003 location) will be advanced using a DPT drill rig to a depth of approximately 50-feet below land surface (ft BLS) or refusal, whichever is encountered first, to characterize the Site-specific lithology. This data will be used to assist in the selection of soil samples and DPT groundwater sampling intervals.

Soil Sampling: Soil sampling will be performed at up to 12 locations (SB001 through SB007, and MAGS001 through MAGS005) as presented on Figure 3 in the FDEP-approved SAWP. Based on an assumed depth-to-water (DTW) of 5 ft BLS, a minimum of three soil samples 0-0.5 ft BLS, 0.5-2 ft BLS, and 2-4 feet below land surface [ft BLS] or water table) will be collected from each of the 12 proposed soil sample locations (36 samples total). Soil samples will be collected by hand auger. A concrete core drill will be used to access soil under the building slab (concrete) and driveway/parking lot (asphalt). Samples will be analyzed for the presence of VOCs via EPA Method 8260 by a National Environmental Laboratory Accreditation Program (NELAP) accredited, fixed-base laboratory. Soil samples will be screened with a photoionization detector (PID) organic vapor analyzer. Supplemental soil samples will be collected from each location and depth interval (via Encore samplers) for analysis of VOCs by the synthetic precipitation leaching procedure (SPLP) should VOC concentrations exceed the leachability-based soil cleanup target levels. For budgetary purposes, it is assumed that approximately half of the proposed soil samples will be analyzed by SPLP for VOCs. Exterior soil samples will be surveyed with a GPS and interior sampling locations will be transcribed using as-builts based on Site features.

MAGS well installation: Five, 2-inch (in.) diameter Schedule 40 polyvinyl chloride (PVC) MAGS wells (MAGS001 through MAGS005) will be installed by hand auger to a depth of approximately 4 ft BLS (or 1-ft above the static water level if the depth to groundwater is different than historically observed). Each MAGS well will be installed with 1-ft of riser and 10-ft of 0.01-in.

slotted well screen extending from approximately 1 to 4 ft BLS. A 20/30 grade environmental sand filter pack will be placed from the bottom of the boring to the top of the well screen. The remaining annular space will be grouted to just below the top of casing.

One vapor monitoring point (VMP001) will be installed by hand auger to monitor the vacuum radius of influence (ROI) and to assess the absence/presence of vapors in the vadose zone.

MAGS well testing: Each MAGS well will be tested for a period calculated to remove one, 10 to 15-ft radius of soil vapor volume using a blower. The test duration is expected to be approximately 1 hour. The vacuum and flow rates used at each MAGS well will be based on the results of a step test at one interior location. The step test will include a minimum of three steps at increasing vacuums to evaluate optimum airflow rates. Vacuum will be monitored at adjacent MAGS wells at approximate 15-minute intervals, as practical, during MAGS testing. After the completion of the study, the MAGS wells will be left in place, capped, and covered with a flush-mount manhole so that they may be converted into soil vapor extraction wells and resampled as necessary in the future.

During testing, soil vapor will be monitored with an organic vapor analyzer equipped with a photoionization detector (PID) utilizing a 10.6 electronic volt lamp. Soil vapor samples will be collected at the end of each MAGS test using a batch-certified “clean” Summa canister provided by the analytical laboratory. The soil vapor samples will be sent to a fixed-based laboratory for analysis of VOCs by the TO-15 method.

DPT groundwater sampling: Geosyntec personnel will observe the collection of DPT groundwater samples at up to 8 locations (DPT001 through DPT008), as shown on Figure 3 of the SAWP.

Groundwater samples will be collected at 4-ft intervals approximately every 10 feet (i.e., 5 to 9 ft BLS, 15 to 19 ft BLS, 25 to 29 ft BLS, 35 to 39 ft BLS, 45 to 49 ft BLS), resulting in 5 samples x 8 locations (40 samples). Sampling intervals may be adjusted based on observed depth to water and Site lithology. Groundwater samples submitted to a NELAP-approved fixed-based laboratory will be analyzed for the presence of VOCs by EPA Method 8260 (full list). No field duplicates will be collected.

Interior monitoring well installation: One monitoring well (MW001) will be installed inside the facility adjacent to the former drycleaning machine. MW001 will be installed manually with a hand auger. The monitoring well target depth will be approximately 12 ft BLS and will be constructed of 1-inch diameter PVC, screened between 7 and 12 ft BLS. A pre-pack screen will be used for hand auger installations.

Field GPS and Interior Mapping: Exterior sampling locations (e.g., DPT groundwater, soil samples, select MAGS wells) will be surveyed throughout the week with a field GPS by Geosyntec personnel. Interior sampling locations will be transcribed using as-builts based on Site features.

Field Deliverable and Draft Summary Figure: Geosyntec has included costs to manage the data generated during this subtask and to develop the following to facilitate discussion with FDEP:

• One figure and table to summarize VOC laboratory analytical results from the DPT groundwater samples;

• One figure and table to summarize VOC laboratory analytical results from soil samples;

and

• One figure and table to summarize VOC laboratory analytical results from MAGS samples.

These data will be provided to FDEP for evaluation to select the locations of proposed monitoring wells to be installed in Subtask 3; data gaps will be addressed during Subtask 3, if practical. If fixed-based laboratory analytical results of soil and DPT groundwater samples indicate that additional sampling will be required to complete delineation, Geosyntec will propose additional sampling locations and corresponding depths. The data will be managed in a database.

Subtask 2 activities will be performed by 2 Geosyntec staff members assuming 1 day for utility locating and mark the borings location (1 Geosyntec staff), 5 days for drilling oversight, 1 day for MAGS well sampling and testing, and close-out tasks at the Site. We have assumed 10-hour per day.

Subtask 3 – Exterior Monitoring Well Installations, Surveying, and Groundwater Sampling

Monitoring well installations: Once the final monitoring well strategy has been established with FDEP, Geosyntec will re-mobilize to the Site to install and sample the monitoring well network.

Geosyntec personnel will observe the installation of up to 4 exterior monitoring wells to evaluate groundwater quality; the tentative locations are presented on Figure 3 of the SAWP. We have assumed the existing utility survey will be sufficient for siting the proposed monitoring well locations; however, should the spray paint be worn away or if there is any uncertainty in utility locations relative to drilling locations, Geosyntec will submit a WCD or TACO to FDEP for a focused utility locating at the drilling locations.

Additional water-table monitoring wells MW002 through MW004 will be installed upgradient, side gradient, and downgradient of the facility using the DPT drilling method. The wells will be constructed of 1-in. diameter Schedule 40 PVC pipe with 10 ft of 0.010-in. slotted well screen, filter pack consisting of 20/30 silica sand, and at least a 0.5-ft thick, fine sand (30/65 silica sand) seal. The remaining annular space will be grouted to land surface with Portland Cement Type I/II and monitoring wells will be completed at the surface with a flush-mount 8-in. manhole and a locking monitoring well cap.

Geosyntec will install one vertical extent monitoring well (MW005) to a depth of 40 feet, if DPT groundwater sampling results warrant vertical delineation. The well will also be constructed with a 10-ft screen depending upon the lithologic information from SB003.

The monitoring wells will be developed until the discharge is relatively sediment-free and sampled no sooner than 24 hours after development.

Monitoring Well Survey: This subtask includes costs for a Florida professional land surveyor to survey the five (5) newly installed monitoring wells. Cost has been included for Geosyntec to oversee the survey.

Groundwater sampling: Geosyntec personnel will collect groundwater samples from the 5 Site monitoring wells. Depth-to-water measurements (DTW) will be collected from the monitoring wells to evaluate groundwater flow direction. The monitoring wells will be sampled using a peristaltic pump in general accordance with FDEP Standard Operating Procedures (SOPs), assuming the DTW and drawdown do not exceed the suction limit of the peristaltic pump. The samples will be stored on ice and shipped to a NELAP approved, fixed-based analytical laboratory under chain of custody for analysis under standard turnaround times. The groundwater samples will be analyzed for VOCs by EPA Method 8260.

Subtask 3 activities will be performed by 1 Geosyntec staff member assuming 2 days for drilling oversight, and 1 day for well sampling, IDW sampling, and close out tasks at the Site. We have assumed 10-hours per day.

Field Deliverable and Draft Summary Figure: Geosyntec has included costs to generate one figure and table that summarize VOC laboratory analytical results from groundwater monitoring well samples. These data will be provided to FDEP for evaluation. The deliverable will include the final surveyor report, monitoring well installation field forms, and groundwater sampling forms.

Subtask 4 – IDW Management

IDW Sampling: The IDW will be sampled prior to profiling. One composite liquid and one composite soil sample will be collected and analyzed for VOCs and metals using the Toxic Characteristic Leaching Procedure. Geosyntec will review the generation of a waste characterization profile as well as the preparation of IDW manifests. Geosyntec will coordinate disposal arrangements for up to 12 drums of non-hazardous IDW. Analytical costs are included to establish the soil and groundwater profiles required by the selected waste hauler. We have assumed field oversight of the drum pickup is not necessary.

For this cost estimate, we have assumed the IDW will not be impacted by PFAS (screening to be performed under HW028A) and Geosyntec will submit a WCD or TACO to FDEP for any change of scope.

Subtask 5 – Site Assessment Report

Following completion of field activities, Geosyntec will proceed with the preparation and submittal of a Site Assessment Report (SAR) documenting assessment activities and summarizing analytical results. This subtask includes costs to generate a SAR that summarizes the analytical results of the assessment activities outlined above and complies with the requirements of Chapter 62-780.600, FAC. The costing included in the CEF/LOE includes the following figures:

• USGS Site Topographic Map

• Potable Well Survey

• Site Layout

• Site Utility Map

• Lithologic Cross Section (1 transect)

• Summary of Soil Analytical Results from 0-0.5, 0.5-2, and 2-4 ft BLS (3 figures)

• Summary of DPT Groundwater Sampling Analytical Results

• Summary of Groundwater Elevations

• Summary of Monitoring Well Analytical Results
