3.0 SAMPLING AND ANALYSIS

3.1 Scope of Work
The Limited Phase II ESA involved the evaluation and sampling of subsurface soil at 11 locations and soil vapor at 11 locations . The depths of borings were between 2 feet to 5 feet below ground surface (bgs) which were based on the client's scope of work. Geoprobe® was used for soil borings. The soil was continuously sampled throughout the depth of the soil borings. All soil samples were visually inspected, and field screened for potential petroleum hydrocarbons exhibiting the greatest potential for impacts (i.e. staining, odor, or highest PID reading).

3.2 Subsurface Sampling
Field activities included collection of subsurface soil and soil vapor samples to assess the subsurface condition at the Subject Property. The Limited Phase II ESA field work was conducted on March 19, 2023 and in accordance with standard environmental engineering practices.

RSB retained GeoRockers Drilling under a subcontractor agreement for drilling work. Mr. Jim Bean, Professional Associate collected subsurface soil and groundwater sam ples. 11 soil borings were drilled to different depths ranging from 2 feet to 5 feet.

The Final Limited Phase II ESA sampling locations are shown in Figure 2 . The field investigation activities that include subsurface samplings are:
• One (1) soil sample collected from each boring. A total, of 11 soil samples were collected. • One (1) soil vapor sample was collected from each boring. A total, of 11 soil vapor samples were collected.

The soil cores were examined in the field to document lithology, color, moisture content, and visual or olfactory evidence of chemical impact. In addition, the samples were scanned with an Organic Vapor Monitor (OVM) equipped with a Photoionization Detector (PID) to detect the presence of volatile organic vapors. Based on the PID readings and visual or olfactory evidence , one soil sample was collected from each boring. The soil samples were placed in laboratory-supplied, method-specified containers. The samples were immediately stored on ice in coolers, and transported under chain-of-custody control to Eurofins - Environment Testing America, a National Environmental Laboratory Accreditation Conference (NELAC) certified laboratory for analysis. At the completion of field activities, the soil cores were backfilled with unused soil cores along with bentonite chips and hydrated with water.

Soil vapor sample locations were augered at the soil sampling locations, sample ports inserted, the annulus space backfilled with sand, and a hydrated bentonite surface seal emplaced. The sampling apparatus was tested for leakage using the shut-in test and the surface seals were leak tested by applying water to a towel and placing around the sample tube at the seal. No leaks were observed during sampling. Summa canister valves were opened to collect samples, valves were closed when the vacuum reached approximately 5” Hg per the attached gauge. The vapor samples were shipped to ALS Global in Salt Lake City, UT.

Please refer to Table 1 for the sampling location, Table 2 for a summary of the analytical results of soil samples, and Table 3 for a summary of the analytical results of soil vapor samples . Non-dedicated equipment and downhole tools were decontaminated before the start of drilling operations and between each boring location. Continuous soil samples from the ground surface to the final completion depth were Limited Phase II Environmental Site Assessment

evaluated at each boring location. A representative portion of every sample was evaluated to determine the sampling location depth. Mr. Jim Bean, Professional Associate, was present at the Subject Property during the drilling operation to monitor the quality of work.

The vapor samples were shipped to ALS Global in Salt Lake City, UT, and the soil samples were shipped to Eurofins in Tustin, CA.

Receipt
The samples were received on 3/20/2023 10:04 AM. Unless otherwise noted below, the samples arrived in good condition, and where required, properly preserved and on ice. The temperature of the cooler at receipt was 3.2º C.

GC/MS VOA
Method 8260B: Insufficient sample volume was available to perform a matrix spike/matrix spike duplicate (MS/MSD) associated with analytical batch 570-313157. The laboratory control sample (LCS) was performed in duplicate (LCSD) to provide precision data for this batch.

No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

GC/MS Semi VOA
Method 8270C SIM: Samples are Dark/Black. SB10-2 (570-131785-10) and SB11-2 (570-131785-11) No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

Metals
Method 6010B: The matrix spike / matrix spike duplicate (MS/MSD) recoveries for preparation batch 570-313229 and analytical batch 570-313660 were outside control limits for one or more analytes, see QC Sample Results for detail. Sample matrix interference and/or non-homogeneity are suspected because the associated laboratory control sample (LCS) recovery is within acceptance limits.

Method 6010B: The serial dilution performed for the following sample associated with batch 570-315464 was outside control limits for Zinc: (570-131803-A-2-F SD ^25)
Method 6010B: The matrix spike / matrix spike duplicate (MS/MSD) recoveries of Barium, Lead and Antimony for preparation batch 570-314037 and analytical batch 570-315464 were outside control limits. Sample matrix interference and/or non-homogeneity are suspected because the associated laboratory control sample (LCS) recovery was within acceptance limits.

No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

Organic Prep
Method 3546: Due to the matrix, the following sample could not be concentrated to the final method required volume: SB10-2 (570-131785-10). The reporting limits (RLs) are elevated proportionately.The final volume was changed from 2mL to 4mL. 8270S I M P A H
No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

VOA Prep
No analytical or quality issues were noted, other than those described in the Definitions/Glossary page.
