Proposed Scope of Work Southgate Cleaners (Former) 5317 U.S. Highway 19 (Currently 5325 U.S. Hwy 19) New Port Richey, Pasco County, FL 34652 Site Assessment and Reporting Task Assignment DC024C ERIC_5228 (Former Facility No. 519500354) Aptim Environmental & Infrastructure, LLC April 18, 2024

The following is the proposed scope of work for DC024C for the former Southgate Cleaners site located in New Port Richey, Pasco County, Florida. The proposed scope of work under Task Assignment DC024C includes the onsite assessment of soil and groundwater, as well as the preparation of a SAR summarizing the findings of the investigation. Maps showing the proposed soil and groundwater sampling locations, are attached for convenience.

Subtask 1-Project Management Project management hours are calculated based on the labor hours anticipated in the scope of work.

Subtask 2-Meeting & MAGS Preliminary Site Activities A preliminary meeting will be held at the former drycleaning location, primarily to meet onsite and discuss the proposed scope of work to be performed with the current property owner and/or the Pet Supermarket manager (current tenants). In addition, prior to the site visit, access requests will be submitted to the City of New Port Richey and Pasco County to determine the access requirements to the ROW of Leisure Lane (to the west), and access to the property east of the Pet Supermarket should be requested.

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 the oversight of 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 The initial assessment activity at 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 twelve (12) MAGS locations inside and outside of the current Pet Supermarket space, generally within the area occupied by the former drycleaner, as shown on Figure 6. The MAGS extraction points will be installed with a 4-inch concrete core machine (if necessary) and a 3-inch auger to place a 5-foot screened interval from 1 to 6 ft bls. If the groundwater is encountered at a depth deeper or shallower than the anticipated interval, the MAGS screened interval may be adjusted 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 each test for analysis by a fixed laboratory for analysis by Modified EPA Method TO-15.

Prior to the installation of the twelve (12) MAGS wells, soil samples will be collected at each location from depths of 6-inches, 2-foot, 4-foot, and 6-foot for fixed laboratory analysis. The location of the proposed MAGS soil samples is shown on Figure 7. 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.

Following the soil sampling and vapor extraction well installations, the MAGS testing will be performed.

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, four (4) vapor monitoring points (VMPs) will be hand installed at select locations (Figure 6) to allow for collection of vacuum measurements at a distance of 5 ft and 10 ft from the vacuum extraction well being tested. The VMPs 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.

Subtask 3-Soil & GW Field Activities DPT Lithologic Core To develop a lithologic cross-section of the site, one (1) continuous soil core will be installed to approximately 60 ft bls or to refusal. The lithologic macro-core® 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 5.

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 5.

The 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.

Soil Sampling Subtask 3 includes the advancement of the remaining six (6) hand-augered borings to an average depth of 6 ft bls to the water table or to the zone of collapse, whichever is first. A lithologic log will be prepared from the notes at each bore. Soil samples will be collected from depths of 6-inches, 2-foot, 4-foot, and 6-foot for fixed laboratory analysis and identification of potential source areas. The location of the proposed soil samples are shown on Figure 7. 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.

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 30 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 8.

Subtask 4-Well Installations After conferring with the FDEP to determine the necessary locations and 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 similar to the piezometers, with a direct push drilling rig. The shallow wells will 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, 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 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 Site Assessment Report, prepared in accordance with the requirements of Chapter 62-780, the Contaminated Site Cleanup Criteria.

Field activities will commence in May 2024, upon approval of the task assignment. The initial field activities will be scheduled for completion by July 26, 2024. Following review of the preliminary data, the well network will be installed and sampling results for FDEP review should be completed before September 20, 2024, and the completed SAR report should be submitted by November 29, 2024. A Task Completion date should be set for December 31, 2024, 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.
