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 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 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 SB001 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 15 locations (SB001 through SB009, and MAGS001 through MAGS006) as presented on Figure 3 in the 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 15 proposed soil sample locations (45 samples total). Soil samples will be collected by hand auger/and or DPT. A concrete core drill will be used to access soil under the building slab (ceramic tile and concrete) and 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: Six, 2-inch (in.) diameter Schedule 40 polyvinyl chloride (PVC) MAGS wells (MAGS001 through MAGS006) 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.

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 DPT007), 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 at 7 locations (35 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.

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 and screened between 7 and 12 ft BLS using a pre-pack screen.

Additional water-table monitoring wells MW002 through MW004 will be installed upgradient, 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 in the rear of the facility. The well screen interval (5 or 10 ft) and depth will be based upon the lithologic information from SB001. For this cost estimate, we have assumed a 40-ft total depth.

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

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.

Subtask 2 activities will be performed by 2 Geosyntec staff members assuming 1 day for utility locating and marking boring locations (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-hours per day.

Subtask 3 – Groundwater Sampling and Surveying

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.

Field Deliverable and Draft Summary Figure: Geosyntec has included costs to generate the following to facilitate the discussion with FDEP:

• One figure and table to summarize laboratory analytical results from the groundwater monitoring well samples;

• One figure with the groundwater elevation contour map.

These data will be provided to FDEP for evaluation. The deliverable will include the final surveyor report, field forms for soil and groundwater assessment, and groundwater sampling forms. If fixed-based laboratory analytical results of soil and groundwater samples indicate that additional sampling will be required to complete delineation, Geosyntec will propose additional sampling locations and corresponding depths. All analytical data will be managed in a database.

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

Subtask 4 – IDW Management

IDW Sampling: The IDW will be sampled to develop a waste characterization profile for the Site.

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 13 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 per- and polyfluoroalkyk substances (PFAS) and Geosyntec will submit a WCD or TACO to FDEP for any change of scope dictated by the PFAS screening results.

Subtask 5 – Site Assessment Report

Geosyntec will prepare and submit 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

• Summary of DPT Groundwater Sampling Analytical Results

• Summary of Groundwater Elevations

• Summary of Monitoring Well Analytical Results

Re: Gentle Touch Dry Cleaning Site 3611 W Hillsborough Avenue Tampa Florida

Dear Mr. Fortes, Action Environmental is pleased to provide you with this proposal you requested for the Gentle Touch Dry Cleaning site located at 3611 W Hillsborough Avenue in Tampa Florida. All boreholes will be cleared by hand to 5 feet. The scope of work is as follows: One deep lithological soil boring to 50 feet. This will be done with DPT and macrocore samplers. The borehole will be abandoned by filling with grout using tremmie pipe. The borehole will be patched matching surrounding material (asphalt or concrete). Fifteen soil borings will be done using hand augers, with some being converted to MAGS wells. The fifteen soil borings will have intervals of .5, .5-2 feet, and 2- 4 feet. The boreholes that aren’t converted to MAGS wells will be abandoned by filling with grout and patched to match surrounding surface. Six MAGS wells will be installed using hand augers to an estimated four feet (depending on depth of groundwater). The MAGS wells will be screened from 4-1 feet with 2 inch diameter .010 slotted screen. They will be finished with 4 inch manholes. Seven groundwater sample locations will be sampled with five intervals each up to 50 feet deep. This will be done with DPT and groundwater sampler points. Samples will be pumped directly through drilling rods using a peristaltic pump. The seven groundwater boreholes will be abandoned with grout and tremmie pipe and patched to match surrounding area when finished. One interior monitor well will be installed using hand auger to as deep as 12 feet. It will be 1 inch diameter with 5 feet of .010 slotted prepacked screen. It will also be finished with a 4 inch manhole. Three exterior monitor wells will be installed using DPT to a depth of 15 feet, each with 10 feet of .010 slotted prepacked screen. One deep exterior monitor well will be installed with DPT to a depth of up to 40 feet with 10 feet of .010 slotted prepacked screen. All four of the exterior monitor wells will be finished with 2x2 concrete pads and 8 inch bolt down manholes. All monitor wells will be developed until clear. All soils and development water will be drummed as well as all decon water. The drums will be staged in a designated location. A core drill will be onsite throughout the duration to core any locations that is necessary. Site will be cleaned and restored at the conclusion of the job.
