Proposed Scope of Work

Care Cleaners of Jacksonville, Inc.

Merrill Station Shopping Center 8011-1 Merrill Road Jacksonville, Duval County, FL 32277 Site Assessment and Reporting Task Assignment DC-TBD ERIC_4516 (Former Facility No. 169500253) Aptim Environmental & Infrastructure, LLC April 15, 2025

The following is the proposed scope of work for the former Care Cleaners of Jacksonville, Inc. site located in the City of Jacksonville, Duval County, Florida. The site remains an active drycleaner and has operated within the same space and under the same name since 1989. The proposed scope of work under this Task Assignment includes the onsite assessment of soil and groundwater, as well as the preparation of a Site Assessment Report (SAR) summarizing the findings of the investigation. Maps showing the proposed soil and groundwater sampling locations are attached.

Subtask 1: Project Management

Project management hours are calculated based on the labor hours anticipated in the scope of work.

Subtask 2: Meeting & MAGS/Soil Sampling/Interior Well Install & Sampling

Preliminary Site Activities A preliminary meeting will be held at the drycleaning location, primarily to meet onsite and discuss the proposed scope of work to be performed with the current property owner or owner representative, the owner of the drycleaner, and the Merrill Station Shopping Center property manager and maintenance manager.

It is noted that a sub-slab soil venting system is operated at the site by Clean Vapor, LLC. The system is comprised of two vertical vent pipes along the north wall of the facility. Additionally, several sample ports were observed on the floor of the facility. During vapor and soil sampling, this system should be deactivated, therefore Clean Vapor would need to be contacted to determine the necessary steps to deactivate and reactive the system during SAR activities.

Since known underground utilities exist surrounding the former drycleaner, a geophysical survey including ground-penetrating radar and electromagnetic induction will be performed to mark and document the onsite utilities.

The preliminary site assessment activities will also include a professional site survey and placement of benchmarks referenced to NAVD88 near the southeast corner of the current building and west of the former drycleaner location.

Modified Active Gas Sampling and Soil Sampling The initial assessment of soils beneath the site will include performing modified active gas sampling (MAGS) to locate potential source areas at the site. The test should assist in identifying the locations of any suspected soil and groundwater areas that deserve additional investigation. APTIM proposes seven

(7) MAGS locations, with three (3) inside main building occupied by the drycleaner, one (1) inside boiler room (a western extension of the main building), and three (3) outside the drycleaner, as shown on Figure 5. The MAGS extraction points will be installed with a 4-inch concrete core machine and a 3-inch auger to place a 4 or 5-foot screened interval from 1 to 5 or 6 ft bls. If groundwater is encountered at a depth deeper or shallower than the anticipated interval, the MAGS screened interval will be adjusted accordingly to place the base of the screen to within 12-inches of the depth to groundwater. The locations will be screened continuously with a photo-ionization detector (PID) in accordance with the MAGS procedures, and an active gas sample will be collected at the end of the test for analysis by a fixed laboratory for analysis by Modified EPA Method TO-15.

Prior to the installation of the seven (7) MAGS wells, soil samples will be collected at each location from depths of 0.5’, 2’, 4’ and 6’ for fixed laboratory analysis of up to 28 samples and identification of potential source areas. The location of the proposed MAGS soil samples is shown on Figure 5. The laboratory samples will be analyzed by Environmental Protection Agency (EPA) Method 8260 analysis for the presence of VOCs (full list) by a fixed based laboratory. Additional material will be collected from each sample location (Encores) for possible SPLP extraction (EPA Method 1312) and analysis of the leachate for volatile organic halocarbons (VOHs) by EPA Method 8260.

During the initial MAGS test, a soil vacuum extraction (SVE) step test will be performed at one location to obtain data which can be used for SVE design, if needed. In addition, the test will determine the relationship of groundwater entrainment and vacuum extraction, if within the capacity of the test equipment. During the step test and MAGS testing, two (2) vapor monitoring points (VMPs) will be hand installed at selected locations (Figure 5) to allow for collection of vacuum measurements at a distance of 5 ft and 10 ft from the vacuum extraction well being tested. The VMP will be 1-inch diameter, with a total depth, screen interval and sand pack intervals similar to the larger diameter extraction wells.

The MAGS wells will be left in place for possible future use in the event active remediation is required, such as SVE at the site. The wells will be capped, covered with fine sand, and grouted to seal the surface. The grout seal can easily be removed for future access to the well screens. The VMPs will be removed upon completion of the vacuum extraction test.

Interior Groundwater Monitor Well Construction and Sampling While onsite, one shallow groundwater monitor well will be hand-installed inside the building at the location shown on Figure 5. The well will be constructed of 1-inch diameter PVC with 5 or 10 ft of fine mesh prepacked 0.006-inch slot screen with a 30/65 sand pack installed as deep as possible, or to 15 ft bls, dependent on the depth to water. Thereafter, the well will be sampled for VOCs (fill list) to obtain preliminary groundwater analytical data.

Soil Sampling After completion of the MAGS testing, the remaining eleven (11) hand-augered borings will be advanced to an average depth of 6 ft bls. A lithologic log will be prepared from the notes at each bore. The remaining soil samples will be collected from depths of 0.5’, 2’, 4’ and 6’ for fixed laboratory analysis and identification of potential source areas. The location of the 18 total proposed soil boring locations are shown on Figure 6. The laboratory samples will be analyzed by Environmental Protection Agency (EPA) Method 8260 analysis for the presence of VOCs (full list) by a fixed based laboratory. Additional material will be collected from each sample location (Encores) for possible SPLP extraction (EPA Method 1312) and analysis of the leachate for volatile organic halocarbons (VOHs) by EPA Method 8260.

Subtask 3: DPT & GW Field Activities DPT Lithologic Core To develop a lithologic cross-section of the site, two (2) continuous soil cores will be installed to approximately 60 ft bls or to refusal. The two lithologic macrocores will be installed by DPT drilling. The continuous soil core will be visually characterized and logged onsite by a geologist. Special attention will be devoted to the identification of any clay-bearing and/or other low permeable strata that may serve as a confining or semi-confining layer. A qualitative moisture assessment will also be logged throughout the entire bore (wet and dry sections). The findings of the lithologic core will be used to construct the appropriate direct push sampling intervals. The proposed locations for the two lithologic borings are shown on Figure 4.

Installation of Piezometers To determine the surficial groundwater flow, three (3) piezometers will be installed following the installation of the continuous soil cores. The DPT rig will install 1-inch diameter polyvinyl chloride (PVC) piezometers screened across the water table to a total depth of approximately 15 ft bls. The shallow piezometer wells will be constructed with 10 feet of 1-inch diameter, Schedule 40 PVC fine mesh pre-pack screen constructed of a 0.006-inch slotted screen with 30/65 sand pack. The proposed locations of the piezometers are shown on Figure 4.

The three piezometers will be surveyed for top of casing elevations and water levels will be measured to determine the general direction of shallow groundwater flow at the site. Thereafter, the piezometers will also be sampled for volatile organic compounds or VOCs (full list) to obtain preliminary groundwater analytical data by utilizing a fixed laboratory. The piezometers will be completed as permanent monitoring points.

Existing Monitoring Wells No known existing monitoring wells were observed on the property.

DPT Groundwater Sampling Groundwater beneath the facility will be characterized by collecting three discrete groundwater samples from proposed direct-push technology (DPT) boring locations. Groundwater samples will be collected from Nine (9) DPT locations using a GeoProbe® screen point sampler. The sampler will be advanced to the target depths of approximately 10, 20, and 30 ft bls for a total of 27 groundwater samples. The exact depth of groundwater sampling will be adjusted according to potential semi-confining layers identified during previous assessment activities including the lithologic borings. The groundwater samples will be submitted to a fixed laboratory for analysis by EPA Method 8260 for the presence of VOCs (full list).

Onsite DPT groundwater sample locations are shown on Figure 7.

Subtask 4: Well Installations After conferring with the FDEP to determine the necessary locations and proposed depths for monitoring wells, based on the site-specific assessment data, three (3) additional shallow and one (1) deep monitoring well will be installed at the site. The shallow wells will be installed by a DPT rig with hollow stem auger capabilities and constructed similarly to the piezometers. The shallow wells will be constructed of 1-inch diameter PVC with 10 feet of fine mesh pre-pack 0.006-inch slotted screen with a 30/65 sand pack and installed to a 15 ft total depth, dependent on the depth to groundwater encountered at the site.

The deep well will be installed by direct push to an estimated total depth of 35 ft bls. The well will be constructed of 1-inch diameter PVC with 5 feet of fine mesh pre-pack 0.006-inch slotted screen with a 30/65 sand pack installed from 30 to 35 ft bls. A two-to-three-foot fine silica sand seal will be installed above the screen and the remaining annulus will be tremie grouted to just below the surface.

Locations and actual installation depths for the monitoring wells will be discussed and approved by the FDEP prior to installation. The proposal funding is currently limited to the 4 additional wells discussed above. If additional wells are deemed necessary, a change order for the additional scope will be requested.

Well Sampling Groundwater samples will be collected from the piezometers (3) and the exterior shallow and deep monitoring wells (4) and the samples will be submitted to a State of Florida-certified fixed-base laboratory for analyses by EPA Method 8260 (full list). In addition, the proposed scope of work includes the collection of samples from up to four (4) selected monitoring wells or piezometers for analysis by DEP SOP: LC-001-3 at the FDEP State Laboratory for PFAS constituents.

During the well sampling event, soil and aqueous samples of the generated investigative-derived waste (IDW) will be sampled for characterization and disposal. Characterization soil samples will be collected for TCLP Extraction by EPA Method 1311 and leachate analysis will be performed by EPA Method 8260 (full list) and the RCRA four metals arsenic (As), cadmium (Cd), chromium (Cr) and lead (Pb) by EPA Method 6010. Liquid IDW samples will be submitted for the same analysis as the soil leachate.

Subtask 5-SAR Reporting The soil and groundwater results will be compiled and summarized in a SAR prepared in accordance with the requirements of Chapter 62-780, the Contaminated Site Cleanup Criteria.

Subtask 6: PFAS Groundwater Sampling Additionally, the proposed scope of work includes the collection of samples from three to four (3 to 4) selected monitoring wells or piezometers for analysis by DEP SOP: LC-001-3 at the FDEP State Laboratory for PFAS constituents.

Schedule Field activities will commence in June 2025, upon approval of the task assignment. The initial field activities will be scheduled for completion by August 29, 2025. Following review of the preliminary data, the well network will be installed and sampling results for FDEP review should be completed before September 23, 2025, and the completed SAR report should be submitted by November 7, 2025. A Task Completion date should be set for January 16, 2026, to allow for review and approval of the SAR, which will be signed and sealed upon submittal.

APTIM proposes to perform this scope of work in accordance with the terms and conditions of the contract executed between APTIM Environmental & Infrastructure, LLC and Florida Department of Environmental Protection No. HW689. APTIM will begin the proposed scope of work upon issuance of the Task Assignment Notification.

a. Installation of two (2) continuous soil cores by direct push to 60 ft bls (or first refusal). The

Macro core will be installed to identify the depth to groundwater and log the lithology at the boring location.

b. Upon completion of the lithologic core, the borehole must be properly abandoned by tremie-grouting the hole under pressure from the bottom to the surface. The approximate proposed location of the DPT lithologic cores are shown on the attached Figure 4.

2. Installation of three (3) Shallow Piezometers (Figure 4):

a. Utilize 3-1/4-inch OD or equivalent rods.

b. 1-inch diameter, schedule 40, PVC well riser and 0.006” slotted screen installed to a total depth of 15 feet bls (or shallower, dependent on the depth to groundwater).

c. 10 feet Pre-Pak Well Screen with a 30/65 grade sand pack.

d. Flush-threaded PVC bottom caps and well riser piping.

e. Allow for borehole collapse to top of screen at 5 feet bls, then place silica sand seal (30/65 grade or equivalent) to 4 ft bls.

f. Grout borehole to within 0.5 ft bls.

g. At surface, flush, 8-inch diameter steel bolt-down manhole set in high strength 2ft x 2ft concrete, pad with water-tight expandable plug well seal.

h. Please utilize a wood frame for the construction of the manhole pad, if not within concrete or asphalt.

i. The piezometers will require development by rigorously over-pumping and surging.

j. Consolidate IDW to an area approved by the shopping center management for future characterization, removal, and disposal.

k. The proposed locations for the three (3) Piezometers are shown on the attached Figure 4.

3. Outdoor DPT Groundwater Sampling (Exterior) – Figure 7:

a. Nine (9) outdoor DPT groundwater sampling locations are proposed within the parking and possible landscaped areas surrounding the site. Three (3) discreet interval screen point groundwater samples will be collected from each location at approximately 10, 20, and 30 ft bls or 40 ft bls (possibly deeper) for the collection of a groundwater samples.

b. All bores, including DPT groundwater locations will be properly abandoned by tremie-grouting the hole under pressure from the bottom up.

c. Please include all equipment and supplies, pumps, tubing, foot valves, connectors, and miscellaneous materials necessary for the collection of the groundwater samples. Sample containers will be provided by the laboratory.

d. The proposed locations for the DPT groundwater sampling are shown in the attached figures.

4. Additional Monitoring Well Installations (Separate Mobilization):

a. Note that the installation of wells will be performed separately from the DPT groundwater sampling, therefore, the Driller should include a separate mobilization for the well installations.

b. After conferring with the FDEP, the quote should include the installation of three (3) additional shallow wells and one (1) deep monitoring well.

c. The shallow wells will be installed similar to the piezometers, utilizing a direct push drilling rig.

The shallow wells will also be similarly constructed of 1-inch diameter PVC with 10 feet of fine mesh pre-pack 0.006-inch slotted screen with a 30/65 sand pack and installed to a 15 ft total depth or shallower, dependent on the depth to groundwater encountered at the site. The wells will also be flush mounted within 8-inch diameter steel bolt-down manholes.

d. The deep well will also be installed by direct push to an estimated total depth of 35 ft bls. The well will be constructed of 1-inch diameter PVC with 5 feet of fine mesh pre-pack 0.006-inch slotted screen with a 30/65 sand pack installed from 30 to 35 ft bls. A two to three foot fine silica sand seal will be installed above the screen and the remaining annulus will be tremie grouted to just below the surface.
