RE: Utility Locating Services – Palm Dry Cleaners, Lutz, Florida

Ms. Westmark, GeoTek Services is pleased to respond to your request for Utility Locating services at Palm Dry Cleaners located in Lutz, Florida. We will scan the area shown in your PDF drawing 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 curbs, vehicles, fences, etc. Our deliverable will be marking paint and/or flags indicating the horizontal 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 utility locating quote for this project is $1,500.00. No out-of-pocket expenses are expected for this project. This quote is valid for sixty days.

Re: Site Assessment Cost Estimate and Level of Effort Palm Dry Cleaners ERIC_4721 14616 Livingston Avenue Lutz, Hillsborough County, Florida

Dear Ms. Schwed:

Professional Service Industries, Inc. (PSI), an Intertek company, is pleased to provide the proposal contained herein to provide a Site Assessment for the Palm Dry Cleaners ERIC_4721, Lutz, Florida.

Included with this proposal is a discussion of project history to date, proposed scope of work, cost estimate and a proposed schedule for completion. According to the signed access form from May 2022, the same property owner is listed in the current (November 2022) property appraiser’s website for Hillsborough County.

PROJECT BACKGROUND

The Palm Dry Cleaners, currently Coin Laundry, is located at 14616 Livingston Avenue, in the Skipper Palms Shopping Plaza on the northwest corner of Bearss Avenue and Livingston Avenue in Lutz, Hillsborough County, Florida. The subject site is located in an area that is mixed-use with commercial and residential development.

The existing Skipper Palms Shopping Plaza was constructed in 1984, when Palm Dry Cleaners began drycleaning operations. A compliance inspection in 1997 documented a Donn Wasco-Clean (Computest

90) Dry-to-Dry machine was installed that year and utilized for the drycleaning operations. The machine utilized an average of 60 gallons per year of perchloroethene as the drycleaning solvent.

mailto:Skylar.Schwed@FloridaDEP.gov

FDEP – Palm Dry Cleaners

A Site Screening Report dated August 23, 1996 identified PCE in three soil samples at concentrations exceeding the leaching to groundwater soil cleanup target level (SCTL) criteria. The samples were collected near the drycleaning machine. On June 16, 1997, the FDEP determined that the site was eligible for the Drycleaning Solvent Cleanup Program with a score of 88.

HSA, Inc. performed a limited soil and groundwater assessment at the cleaners in 1998. The report identified PCE impacted soil and groundwater at the site. The assessment did not identify the horizontal and vertical extent of the solvent impacted soil and groundwater; however, it was documented the impacts were in the surficial sands and the underlain clay layers.

A Site Assessment was performed for the facility in 1999 by PSI for the previous property owner, United Investors Realty Trust. The assessment included groundwater screenpoint sampling, soil sample collection and analysis, monitoring well installations and groundwater sampling. The assessment revealed a cover subsidence sinkhole immediately north of the drycleaning tenant space and extended onto the adjacent property to the north. Lithologic profiling identified sand inside the sinkhole and depth to a confining unit inside the sink could not be evaluated at the time. The assessment also revealed VOH impacts to the vadose zone soils beneath the drycleaner and immediately north of the building at levels exceeding commercial direct exposure SCTLs. The highest concentration of PCE in the soil was reported at 11,100 mg/kg. Assessment of the groundwater identified VOH compounds in the shallow and intermediate zones at concentrations exceeding natural attenuation default (NADC) criteria. The highest concentrations in the groundwater were found in the vicinity of the higher impacted soils and at the edge of the sinkhole.

The horizontal and vertical extent of VOH impacts to the soil and groundwater were not fully identified during the assessment.

Based on the site conditions from the site assessment, PSI completed a Remedial Alternatives Analysis (RAA) for the Palm Dry Cleaners facility on behalf of the previous property owner in January 2000 which recommended shallow zone source removal by Multi-Phase Extraction (MPE) followed by an in-situ chemical oxidation. However, according to available documents, the remediation of the VOH impacts was not implemented at the Palm Dry Cleaners.

A Site Assessment Work Plan was submitted by PSI, revised per FDEP suggestions, resubmitted and approved in August 2022, and follows the guidelines presented in the July 2022 FDEP Contractor’s Workshop. Bids and quotations were solicited from various firms to provide services for the assessment.

A copy of all quotations are attached.

PSI, therefore, proposes to conduct the Site Assessment at the Palm Dry Cleaners, as presented below.

1. Pre-Project Activities

• Utility Clearance/ Well Permits/ GPR Survey

• Professional Land Survey

• Existing Monitoring Well Sampling

2. Initial Mobilization

• Lithologic Boring

• Interior Soil Borings / Soil Sampling/ MAGS Well Installation

• Interior Monitoring Well Installation

• MAGS Testing

PROPOSED SCOPE OF WORK

Subtask 1. Project Management

This scope is provided for in the template worksheets.

Subtask 2. Notification/ Utility Locate / GPR Survey / Land Survey / Existing Monitoring Well

Sampling

Prior to mobilizing field crews, PSI will provide several site assessment preparation elements.

2.1 Notification – The tenant and/or owner of the property will be notified of the planned field activities.

2.2 Utility locates – Sunshine 811 will be notified for utility locates.

2.3 GPR – A ground penetrating radar (GPR) survey will be performed to determine the presence and location of subsurface utilities leading up to the building.

2.4 Land Survey – A Specific Purpose Survey with locations of improvements will be performed by a

Florida Licensed Surveyor and Mapper. The top-of-casings for the nine existing on-site monitoring wells will be surveyed, as will any additional newly installed wells.

2.5 Existing Well Sampling – Nine existing monitoring wells will be sampled to evaluate and preliminarily assess the current groundwater quality at the site. The groundwater samples will be analyzed for VOHs and VOAs by EPA Method 8260. The groundwater flow direction is anticipated to be towards the west. Four groundwater wells will be sampled for the potential presence of PFAS compounds. We anticipate selecting a source area, one sidegradient well, and one downgradient well with subsequent analysis for PFAS compounds by the FDEP Central laboratory in Tallahassee which will be conducted under a separate Task Assignment.

Subtask 3. Initial Mobilization

PSI will conduct an initial mobilization to consist of the following items.

3.1 Lithologic Boring Installation – Continuous lithologic profile to 50 feet bls or refusal depth will be performed utilizing a DPT rig equipped with a macrocore soil sampling system. The target geologic formation will be the Hawthorn clay layer.

3.2 Interior Soil Borings / Soil Sampling/ MAGS Well Installation – Six soil borings will be installed inside the building to evaluate source areas and potential contaminant release points near the former drycleaning machine, former spotting board and floor drains. Two soil borings will be installed outside the building (one near the back door and another near the former drycleaning machine). Soil borings will be hand-installed with a core drill and hand auger to the water table and will be screened utilizing an OVA-PID. Sample depth intervals will follow FDEP protocols and include 0 - 0.5 feet bls, 0.5 - 2 feet bls, 2 - 4 feet bls, 4 - 6 feet bls, 6 - 8 feet bls and 8 - 10 feet bls.

The water table is estimated to be approximately 10 feet bls. Soil samples will be analyzed for VOHs and VOAs by EPA Method 8260.

Five MAGS wells will be installed inside five of the six soil borings inside the building and the two locations outside of the building (back door and former drycleaning machine). The MAGS wells will be installed approximately 1-foot above the groundwater table. Each MAGS well will be installed to 8 feet bls and constructed with 2-inch diameter 7-foot lengths of screen (0.01-inch slot size) and 1 foot of casing. The MAGS wells will be completed at the surface with a 2-inch bronze metal cleanout plug. The MAGS wells will be installed as permanent for later use as SVE wells, if necessary.

3.4 Interior Monitoring Well Installation - A two-inch diameter monitoring well will be installed in one of the soil borings inside the building near the former drycleaning machine location. The well be installed to approximately 14 feet bls (if possible) with 10 feet of screen (0.01-inch slot size).

The well will be completed at the surface with a 2-inch bronze metal cleanout plug.

3.5 MAGS Testing - A well head assembly will be constructed to allow for vacuum, flow and temperature measurements from each MAGS point, and for each portion of the test. During each MAG point test, flow rate, well-head vacuum, and vacuum influence (measured from other MAG points, existing vacuum monitoring points and the horizontal SVE wells) will be measured approximately every 15- minute interval. The vacuum will be varied at the well head, starting from a low applied vacuum and incrementally increasing the vacuum. During each applied vacuum, the vapor flow rate will be measured for the purpose of determining the relationship of applied vacuum to flow rate. During this test, at each vacuum level, the vacuum influence will be measured from the nearby MAGs points or vapor monitoring points to assess the Radius of Influence (ROI). This test will also provide an indication of the maximum well head vacuum without excessive water entrainment. Vapor samples will be collected using SUMMA® canisters for analysis of volatile organic compounds using EPA Method TO-15. It is anticipated that one vapor sample will be collected for each well head test. The sample will be collected at the end of the test.

3.6 Groundwater Screenpoint Sampling - Geoprobe (Direct Push) – Based on groundwater sampling data provided from the existing on-site monitoring wells, soil assessment and MAGS testing data, additional groundwater screenpoint sampling may be needed to determine additional horizontal and vertical groundwater contaminant plume configuration. A DPT drilling rig will be used to evaluate vertical migration of potential contamination from the former drycleaner at up to four locations. It is anticipated that three depth intervals will be evaluated from site lithology and the intervals will be determined from continuous macrocore samples at each location. Based on previous assessment information, the depth intervals will be anticipated at 11-15 feet bls, 21-25 feet bls and 31-35 feet bls. The groundwater samples will be submitted to a fixed-base laboratory for a standard turnaround time for VOH and VOA analysis.

3.7 Exterior Soil Boring Installation/ Soil Sampling – Exterior soil borings will focus on the main area of soil impacts identified during the 1998 and 1999 assessment activities. The area exceeding SCTLs on the outside of the building was immediately north of the former drycleaning machine location. Soil borings will be installed to the water table immediately north of the building utilizing a hand auger and DPT drilling rig. A soil boring will be installed near the front door and back door/ dumpster location of the facility, and near the lint trap. Soil samples will be collected from hand augered soil samples and macrocore sleeves and screened with an OVA-PID. The water table is estimated to be approximately 10 feet bls. Soil samples will be retained for laboratory analysis from depth intervals 0-0.5 feet bls, 0.5-2 feet bls, 2-4 feet bls, 4-6 feet bls, 6-8 feet bls and 8-10 feet bls. Soil samples will be analyzed for VOHs and VOAs by EPA Method 8260. Soil samples will be collected with an Encore sample such that SPLP analyses may be able to be run should the results indicate the concentrations of the contaminants of concern are above the Leachability criteria and below the Residential Exposure, of Chapter 62-777, FAC, and per FDEP approval.

3.8 Monitoring Well Installation - Geoprobe (Direct Push) – Subsequent to the preliminary groundwater testing program using existing monitoring wells and groundwater screenpoint sampling data, it is estimated that additional cluster well sets will be required. Each cluster set will consist of a shallow, intermediate and possibly deep wells. Although the exact depths of the wells will be determined by the groundwater testing of existing wells and the results of the lithologic profiling, for estimating purposes, the well screen intervals will be as follows:

• Shallow (up to 3 wells): 5- 15 feet bls;

• Intermediate (up to 4 wells): 20 - 25 feet bls and/or 30 – 35 feet bls;

• Deep (up to 4 wells): 40 - 45 feet bls; (depending on necessity)

Each shallow monitoring well will be installed with a DPT drilling rig and will be constructed with

1-inch diameter 10-foot lengths of pre-packed screen (0.01-inch slot size) and packed with 20/30 silica sand followed by a 30/65 silica sand seal and grouted to surface. Intermediate and deep wells will be constructed with 1-inch diameter 5-foot lengths of pre-packed screen (0.01-inch slot size) and packed with 20/30 silica sand followed by a 30/65 sand seal and grouted to surface. The wells will be completed at the surface with an 8-inch manway and a 2 ft by 2 ft concrete pad. Each well will be developed until the discharge water is visually clear. All drill cuttings and development fluids will be containerized for later transport and disposal.

3.9 Groundwater Sampling – Groundwater samples will then be collected from the newly installed monitoring wells and analyzed for VOHs and VOAs by EPA Method 8260. Natural Attenuation and Remedial Parameters may also be collected from an upgradient well, a source area well and a downgradient well, if necessary. Groundwater sampling will be conducted in general accordance with FDEP’s Standard Operating Procedure (SOP) DEP-SOP 001/01 for Field Activities. Equipment blanks and duplicates will not be collected for Quality Assurance/Quality Control purposes per recent guidance from the Waste Site Cleanup Section. Groundwater purging and sampling will be conducted in accordance with the FDEP SOP requirements.

Top of casing elevations will be measured for all located wells to an established benchmark. Depth to groundwater will be recorded at each well so that a groundwater iso-contour flow map can be generated.

3.10 Existing Well MW-4 Abandonment – MW-4 is a 25-foot deep 2-inch monitoring well and has a screened interval of 0-25 feet bls. PSI recommends abandonment of this well and replace the well with a cluster set of shallow, intermediate and deep monitoring wells at this location.

3.11 Data Evaluation – The data collected from the activities described above will be evaluated and recommendations for additional assessment will be presented to the FDEP for approval prior to proceeding with an additional mobilization.

3.12 Investigation Derived Waste (IDW) – All soil cuttings, development water and purge water will be containerized in 55-gallon drums, labeled and staged on-site for characterization. Once the results are received, the drums will be transported for disposal / treatment at an approved facility.

It is estimated a total of 5 drums will be utilized for the assessment.

3.13 Deliverables – The following deliverables will be submitted to the FDEP upon completion of the site assessment:

• Site Assessment Report which will include a conceptual site model,

• Separate email with PFAS results. If the PFAS levels are above the EPA Health Advisory Level

(HAL) of 70 nanograms per liter (ng/L = parts per trillion), an email summary with map and brief information will be submitted within 48 hours of laboratory results. If the results are below the HAL, the email submittal will be provided concurrently, but separately, from the Site Assessment Report.

• ADaPT deliverable,

• Investigative Derived Wastes (IDW) manifests.

3.14 Quality Assurance / Quality Control – All field work will be performed in accordance with the most current version of the FDEP Standard Operating Procedures guidelines. In addition, an FDEP approved fixed-base laboratory will perform all analyses associated with the delineation of the contaminant plume at the subject site. Please note that recent FDEP guidelines do not require the collection or analysis of trip blanks, equipment blanks, or duplicate samples.

3.15 Health and Safety – Drilling and sampling operations will be directed by a PSI field supervisor, and field personnel will be OSHA trained in accordance with 29 CFR 1910.120.

3.16 ADaPT – The laboratory data will be validated using the FDEP’s Automated Data Processing Tool

(ADaPT) program to ensure that all required quality control targets were met. The data will be uploaded to the FDEP portal for review and approval.

Scope of Work

Utility Locating: We understand the scope of work on this project is to search for underground utilities in the areas defined by the client. We will attempt to trace any utilities for which structures are visible from the work area. Utilities will be marked on the surface using spray paint or other appropriate means. The client will be responsible for providing drawings or notifying GPRS of any utilities known to be entering the work area for which there are no apparent surface features or structures that are visible from the work area. To avoid additional charges, the areas should be laid out, marked, and cleared of obstructions prior to our arrival.

Location Description Size Exterior 40000 SF

Equipment Underground Scanning GPR Antenna. This GPR Antenna uses frequencies ranging from 250 MHz to 450 MHz and is mounted in a stroller frame that rolls over the surface. Data is displayed on a screen and marked in the field in realtime. The surface needs to be reasonably smooth and unobstructed to obtain readable scans. Obstructions such as curbs, landscaping, and vegetation will limit the efficacy of GPR.

The total effective scan depth can be as much as 8’ or more with this antenna but can vary widely depending on the soil conditions and composition. Some soil types, such as clay, may limit maximum depths to 3’ or less. As depth increases, targets must be larger to be detected, and nonmetallic targets can be challenging to locate. The depths provided should always be treated as estimates as their accuracy can be affected by multiple factors. For more information, please visit: Link

Electromagnetic Pipe Locator. This receiver can passively detect the signals from live AC power or radio signals traveling along some conductive utilities. Operators can connect a transmitter directly to accessible metallic pipes, risers, or tracer wires to generate a current at a specific frequency. The receiver can then detect the resulting signal along the pipe or tracer wire. Various factors may impact this device's effectiveness, including (but not limited to) access to the utility, conductivity, grounding, and interference from other utilities.

The depths provided should always be treated as estimates as their accuracy can be affected by multiple factors. For more information, please visit: Link

Traceable Rodder. The rodder consists of a copper wire encased in fiberglass. This device is pushed through a pipe with direct access, such as a sewer line at a cleanout or a storm drain catch basin. Operators then induce a current on the wire and trace the signal from the surface. The maximum traceable depth is 10’ depending on the soil conditions, and the maximum distance is 200’. Inserting the rodder into deeper pipes within manholes may not be feasible depending on site conditions. GPRS will not access electrical conduits. The signal is not detectable through metallic pipes. For more information, please visit: Link

GPS. This handheld unit offers accuracy down to 4 inches; however, the accuracy achieved will depend on the satellite environment at the time of collection and is not considered surveygrade. Features can be collected as points, lines, or areas and then exported as a KML/ KMZ or overlaid on a CAD drawing.
