May 26, 2023

Ms. Brittany Plyer Florida Department of Environmental Protection 2600 Blair Stone Road Tallahassee, FL 32399-2400

Subject: Scope of Work and CEF/LOE – Site Assessment

Former Peacock Dry Cleaner 5021 Gulfport Boulevard Gulfport, Florida 33707 FDEP Site ID No. ERIC_5330

Dear Ms. Plyer:

Geosyntec Consultants, Inc. (Geosyntec) has prepared this Scope of Work (SOW) and Level of Effort (LOE) for site assessment activities at the Former Peacock Dry Cleaner (“Site”) located in Gulfport, Florida (ERIC_5330). Geosyntec prepared this LOE based on Geosyntec’s March 15, 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. A cost estimating form (CEF) and LOE is provided as Attachment A.

Geosyntec obtained three bids from licensed and qualified contractors for utility locating, concrete coring, drilling, and investigation derived waste (IDW) transportation and disposal. A cost comparison is provided in Attachment B. Geosyntec recommends the following subcontractors based on lowest cost and/or earliest availability among the qualified bidders:

Underground utility locating – GeoTek Services, LLC Concrete coring – Action Environmental DPT groundwater sampling and monitoring well installation – Action Environmental

(earliest availability and second lowest cost) IDW transportation and disposal – Erwin Remediation, Inc.

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

The figures and Table 1 from the SAWP have been revised to reflect FDEP’s comments and are included in Attachment C.

Subtask 1 – Project Management

Costs associated with this subtask are directly computed.

Subtask 2 – Soil Sampling and Modified Active Gas Sampling

This subtask includes costs to conduct a private utility locate, hand auger soil sampling, and modified active gas sampling (MAGS). These activities are summarized below and are anticipated to be performed during a single mobilization.

Private Utility Locate

Geosyntec personnel will mobilize to the Site to oversee a private underground utility survey.

Identified utilities inside and around the Site building will be mapped by Geosyntec staff using a Global Position System (GPS) unit following the private underground utility survey. As a cost savings, Geosyntec assumes that the locator will also scan each location proposed under Subtask 3 for underground utilities while on-Site.

Concrete Coring

Geosyntec personnel will oversee coring activities within the Site building by a concrete coring contractor. Based on observations during the SAWP Site visit, it is anticipated that the foundation inside the Site building may be up to 12 inches thick. The contractor will core the concrete at locations MAGS001 through MAGS005, VMP001, and VMP002 (Subtask 2), and MW001 and MW002 (Subtask 3).

Unknown Manhole Assessment

Geosyntec will attempt to sample soil and/or groundwater encountered in the three unknown manholes in the Storage Area of the Family Dollar. Either a grab soil sample or grab groundwater sample will be collected from each location depending on conditions observed and if Geosyntec is able to chip/break open the grouted locations. The samples will be analyzed using United States Environmental Protection Agency (EPA) Method 8260 (full list) for volatile organic compounds (VOCs) by a state of Florida certified, National Environmental Laboratory Accreditation Program (NELAP) accredited fixed-based laboratory.

Soil Sampling

Soil samples will be collected at up to seven (7) locations (MAGS001 through MAGS005, VMP001, and VMP002) to identify the location of potential source area(s). A hand auger will be used to collect samples from the following intervals: 0 to 0.5, 0.5 to 2, and 2 to 4 (or the water table if encountered shallower than 4 ft BLS). The depth of each soil boring may be adjusted based on the observed depth to water encountered during soil boring completion.

Soil samples will be screened with a photo-ionization detector (PID) organic vapor analyzer.

Should observations suggest that a separate discrete depth should also be sampled, the sample will be collected and held for subsequent analysis, pending discussions with FDEP.

The soil samples will be analyzed using EPA Method 8260 (full list) for VOCs by a state of Florida certified, NELAP-accredited fixed-based laboratory. At each soil sample location, a 25-gram, Encore sample will be collected to evaluate soil leachability. The samples will be placed on hold with the analytical laboratory. If leachability criteria for constituents are exceeded in soil sample(s), and concentrations are below the Residential Soil Cleanup Target Level (SCTL), Geosyntec will inform FDEP and request approval to instruct the analytical laboratory to analyze the corresponding Encore sample using the Synthetic Precipitation Leaching Procedure (SPLP).

For budgetary purposes, it is assumed that approximately half of the proposed soil samples (10) will be analyzed by SPLP for VOHs.

Exterior soil samples will be surveyed with a GPS. Interior sampling locations will be transcribed using as-builts based on Site features.

MAGS

Five, 2-inch diameter Schedule 40 polyvinyl chloride (PVC) MAGS wells (MAGS001 through MAGS005) will be installed at the approximate locations shown on Figure 1 included in Attachment C by hand auger to a depth of approximately 3 ft BLS (i.e., 1-ft above the anticipated depth to groundwater). Each MAGS well will be installed with 1-ft of riser and 2-ft of 0.01-inch slotted well screen extending from approximately 1 to 3 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. A temporary grout patch will be placed on top of a PVC cap that will be placed on each well to match existing grade and protect the well fo9llowing installation and testing. Exterior MAGS locations will be surveyed with a GPS. Interior sampling locations will be transcribed using as-builts based on Site features.

Three, 1-inch diameter Schedule 40 PVC vapor monitoring points (VMPs; VMP001 through VMP003) will be installed at the approximate locations shown on Figure 1 included in Attachment C using a hand auger to a depth of approximately 3 ft BLS (or 1-ft above the anticipated depth to groundwater). Each VMP will be installed with approximately 1-ft of 1-inch diameter Schedule 40 PVC riser and 2-ft of 1-inch diameter Schedule 40 PVC screen slotted at 0.010-inches extending from approximately 1 to 3 ft BLS. A 20/30 grade environmental sand filter pack will be placed from the bottom of the boring to the top of the VMP screen. The remaining annular space will be grouted to just below the top of casing. A temporary grout patch will be placed on top of a PVC cap that will be placed on each well to match existing grade and protect the VMP following installation and testing. VMP locations will be transcribed using as-builts based on Site features.

Quotes for MAGS supplies are included in Attachment D.

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 up to 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 to evaluate optimum air flow rates. Vacuum will be monitored at adjacent MAGS wells, VMPs, and monitoring wells (see Subtask 3) at approximate 15-minute intervals, as practical, during MAGS testing.

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 (5 total) 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.

Field Deliverable and Draft Summary Figures

Geosyntec has included costs to generate one figure and table that summarize VOC laboratory analytical results from soil samples and one figure and table that summarize VOC laboratory analytical results from MAGS samples. These data will be provided to FDEP for evaluation. Data gaps will be addressed during Subtask 5, if warranted.

Subtask 3 – DPT Investigation and Monitoring Well Installation

This subtask includes costs to conduct direct push technology (DPT) groundwater sampling, DPT soil sampling, and monitoring well installation during a single mobilization. These activities are summarized below.

Lithologic Soil Boring and DPT Groundwater Sampling

Geosyntec will mobilize to the Site to oversee the advancement of one lithologic soil boring (LSB001) using a DPT drill rig to a depth of approximately 50 ft BLS (or refusal, whichever comes first) to characterize the Site-specific lithology. Geosyntec proposes to install the LSB001 south of the Site building between the locations of the former temporary monitoring wells (Figure 2 of the SAWP included in Attachment C). This data will be used to assist in the evaluation of DPT groundwater sampling intervals and better understand the lithology at the Site.

Geosyntec will also collect groundwater samples using DPT at up to seven (7) locations (DPT001 through DPT007) as shown on Figure 2 of the SAWP included in Attachment C. Groundwater samples will be collected at 4-ft intervals approximately every 10 feet (i.e., 6 to 10 ft BLS, 16 to 20 ft BLS, 26 to 30 ft BLS, and 36 to 40 ft BLS) to an estimated 40 ft BLS or refusal, whichever comes first. Sampling depths may be adjusted based on the results from LSB001. Groundwater samples submitted to a NELAP-approved fixed-based laboratory will be analyzed for the presence of VOCs by EPA Method 8260 (full list).

Geosyntec has included costs to generate one figure and table that summarize VOC laboratory analytical results from the DPT groundwater samples. If fixed-based laboratory analytical results of DPT groundwater samples indicate that additional groundwater sampling will be required for delineation of groundwater impacts, Geosyntec will propose additional sampling locations and corresponding depths and/or monitoring wells, if warranted.

Monitoring Well Installation

Five monitoring wells (MW001 through MW005) will be installed at the approximate locations shown on Figure 2 of the SAWP included in Attachment C. Monitoring wells MW001 and MW002 will be installed using a hand auger and constructed of 2-ft of 1-inch diameter Schedule 40 PVC riser and either 5-ft or 10-ft of 1-inch diameter Schedule 40 PVC pre-packed well screen.

If the borehole does not collapse, the monitoring wells will be screened from approximately 2 to 12 ft BLS. If the borehole collapses, then the monitoring wells will be screened from 2 to 7 ft BLS.

Monitoring wells MW003 through MW005 will be installed using DPT and constructed of 2-ft of 1-inch diameter Schedule 40 polyvinyl chloride (PVC) riser and 10-ft of 1-inch diameter Schedule 40 PVC pre-packed well screen extending from approximately 2 to 12 ft BLS.

If the formation does not collapse around the PVC during installation, a filter pack consisting of 20/30 silica sand will be placed around the well screen to approximately 0.5-ft above the top of the screen followed by 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 6- or 8-inch diameter manhole and a locking monitoring well cap. The monitoring wells will be developed until the discharge is relatively sediment-free. The top-of-casing elevation and horizontal coordinates of each monitoring well will be measured by a Florida-licensed professional surveyor as part of Subtask 4.

Field Deliverable and Draft Summary Figure

Geosyntec has included costs to generate one figure and table that summarize VOC laboratory analytical results from DPT groundwater samples. These data will be provided to FDEP for evaluation. Data gaps will be addressed during Subtask 5, if warranted.

Subtask 4 – Monitoring Well Sampling and Surveying

This subtask includes costs to collect groundwater samples from the newly installed monitoring wells and oversee a professional survey. These activities are summarized below.

Monitoring Well Sampling

Subtask 4 includes costs for Geosyntec personnel to mobilize to the Site to conduct groundwater sampling activities of Site monitoring wells. Prior to sampling, depth to water measurements will be collected from Site 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). 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.

Screening for per- and polyfluoroalkyl substances (PFAS) has been authorized by FDEP for the two monitoring wells under task assignment HW028A.

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.

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. Data gaps will be addressed during Subtask 5, if warranted.

Subtask 5 – Preliminary Data Review Teleconference

This subtask includes time to prepare for and conduct a teleconference with FDEP to discuss the Subtask 2 and Subtask 3 results. If warranted and agreed upon during the teleconference, additional assessment activities may be proposed to complete Site assessment under Chapter 62-780, FAC.

Presumptive remedies, if warranted, will also be discussed during this teleconference.

Subtask 6 – IDW Management

This subtask includes costs associated with the transportation and disposal of IDW generated as part of Site assessment activities. The soil and liquid IDW will be containerized in new 55-gallon drums and staged on-Site at a location designated by Geosyntec. It is estimated that the following number of drums will be generated as part of each subtask.

Soil Drums Liquid Drums

Subtask 2 – Soil Sampling and MAGS 1 1

Subtask 3 – DPT Soil and Groundwater Sampling, and Monitoring Well Installation

1 2

Subtask 4 – Monitoring Well Sampling 0 1

Total Drums for All Subtasks 3 4

The IDW will be sampled prior to profiling. One composite liquid and one composite soil sample will be collected ana 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 7 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.

Subtask 7 – 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.

RE: Utility Locating Services – Peacock Dry Cleaners, Gulfport, Florida

Ms. Cain, GeoTek Services is pleased to respond to your request for Utility Locating services at the Peacock Dry Cleaner site located in Gulfport, Florida. We will scan a 10’ x 10’ area around 20 proposed bore locations with the goal of locating underground utilities.

We can only scan the easily accessible open areas for utilities. Note that we cannot scan beneath fixed objects such as landscaping, fencing, buildings, or vehicles. We will scan as close as reasonably possible to fixed objects such as brush, curbing, etc. Our deliverable will be marking paint and/or flags indicating the location of potential underground utilities. It is the client’s responsibility to protect and preserve all marks.

We will use both Electromagnetic Induction instruments as well as Ground Penetrating Radar (GPR) to detect objects below the surface. Due to the nature of sub-surface detection and the physical laws governing radio wave propagation, some buried objects may not be detectable due to depth, obscuration, or a weak radar signature. GeoTek Services will use industry standard best practices to locate sub-surface objects, however some objects may not be detectable. Geotek Services does not guarantee that all underground objects can be found. GeoTek Services assumes no liability for any damages.

We request access to any as-built site plans of the scan areas prior to rendering services. Our quote for this effort is $750.00. No out-of-pocket expenses are expected for this project. This quote is valid for sixty days.

SITE LINES LLC PROPOSAL

SITE LOCATION

Peacock Dry Cleaner Site – 5021 Gulfport Boulevard, Gulfport, FL

PROPOSED SCOPE OF WORK

Site Lines (“Company”) will use Ground Penetrating Radar (GPR) and conventional electromagnetic (EM) pipe and cable locators to determine the location of underground utilities at the site identified by Geosyntec (“Client”). Of specific concern is the utilities within a 10-foot radius of approximately 20 proposed sample locations.

RESULTS OF THE INVESTIGATION

The estimated depth and location of utilities identified during the investigation will be marked on the ground surface using spray paint or other method to be agreed upon by the parties. The American Public Works Association Uniform Color Codes for the marking of underground utilities will be used.

PROJECT FEE

The fee to complete the project as described within this proposal is: Eight Hundred Dollars [$800.00].

Client shall pay Company in full within thirty (30) days of the invoice date, unless the parties have agreed to another payment arrangement in writing. If during the investigation, Company determines that the goals of the project cannot be achieved with the resources available to Company, Company will notify Client as soon as reasonably possible. Under such circumstances, Company will charge Client only for time expended and materials used to date.

CLIENT REQUIREMENTS

Client is responsible for all site access, maintenance of traffic (MOT), site clearing and/or any other logistical considerations necessary to conduct the utility locate.

Client will also provide all pertinent maps of the project site, including those that show the boundaries of the utility locate, pertinent landmarks, and known utilities (if available). Company is not a substitute for Chapter 556, Florida Statutes.

Accordingly, Client is responsible for calling Sunshine State One Call of Florida

(811) before undertaking any invasive activities, whether through Company, any other entity, or on its own.

DESCRIPTION OF COMPANY INVESTIGATION AND LIMITATIONS

A GSSI SIR-4000 GPR system will be used with a 900, 400, or 270 megahertz antenna configuration depending on site conditions and desired targets. The GPR will assist in locating nonmetallic and metallic utilities. Physical surface conditions, subsurface conditions and technical limitations effect the ability of GPR to resolve targeted utilities and/or subsurface structures. Depth and/or diameter of the utility, soil type, moisture/ionic content of the soil, and electrical properties of the soil compared to that of the utility can prevent the GPR from identifying utilities at the site. The diameter of a utility cannot be determined by GPR data. Estimated depths of utilities are directly affected by soil conditions and the material of the utility. A margin of error of +/- 20-25% in depth should be expected when performing invasive activities.

An RD 8000 will be used for the EM survey. Electromagnetic induction which transmits a signal directly into the desired target and passive power detection which locates naturally occurring magnetic fields in energized lines will be identified by detecting and following the signals with a receiver. The EM survey will assist in finding only metallic utilities. The magnetic field and/or induced signal should emanate from the target in a circular geometry. When this occurs, the receiver will receive its peak signal directly above the target. However, when metallic utilities are running near each other, or there is environmental interference from fences, cars or overhead power lines, the signal can become distorted and the peak no longer can be directly over the utility. Care must be taken when doing any invasive work around the utilities. A margin of error of +/- 20-25% in depth should be expected when performing invasive activities. Company’s personnel are highly experienced and certified operators of GPR and EM pipe and cable locators.

Due to the limitations described above, when Client is working around indicated utilities, a minimum of two (2)-feet clearance from either side of the marked utility will be maintained. For absolute confirmation, Client is responsible for exposing any indicated underground utility.

Company will conduct utility investigations in accordance with the level of care and generally accepted professional practices as ordinarily exercised by members of the same profession practicing in the same locality under similar conditions.

REPRESENTATIONS AND WARRANTIES

Neither Company nor its employees or agents are licensed surveyors under Florida law, nor do they represent themselves as such. Accordingly, the work Company is to perform is not a substitute for work typically completed by a licensed surveyor.

Company specifically and expressly disclaims any liability for any type of property damage or personal injury, including but not limited to death, arising from client’s failure to determine that the services of a licensed surveyor are necessary or to retain a…
