1.0 INTRODUCTION
Professional Service Industries, Inc. (PSI) was retained by Hisense Reus LLC to perform a subsurface investigation for the possible environmental impact to the subsurface at the subject property.

1.1 SITE DESCRIPTION AND BACKGROUND
The site is undeveloped land located on the south side of Railroad Avenue, between S. Linden Avenue and S. Spruce Avenue, in South San Francisco, California (Figure 1). The subject property consists of a narrow property that was a former railroad right of way and totals 2.25 acres. Previous sampling was conducted on the property with 25 soil samples collected from 0.5 feet below ground surface. All the soil samples were analyzed for lead and arsenic, four samples were analyzed for nine metals, thirteen samples were analyzed for pesticides, and three samples were analyzed for polynuclear aromatic hydrocarbons (PAHs). None of the pesticides, PAHs, or metals, other than lead, had concentrations greater than their Environmental Screening Level (ESL). Lead was found in three of the 25 soil samples above the ESL. Additionally, six soil samples had lead concentrations greater than the screening criteria of ten times the soluble threshold limit concentration (STLC). These samples would typically be analyzed for soluble lead using a Waste Extraction Test (WET) to determine whether the soluble lead concentration was hazardous and would require disposal as a hazardous waste once designated as a waste. It does not appear that a WET was conducted on the samples above the ten times screening criteria.

Based on a quarterly groundwater report for a site, approximately 100 feet east of the subject property (former Praxair), groundwater is approximately 6 to 8 feet below ground surface (bgs).

Hisense requested this subsurface investigation to attempt to collect the following information. • Lateral and Vertical Extent of Lead Impact, if present. • Additional evaluation of other possible contaminants. • Evaluate groundwater for potential impact.

2.0 SUBSURFACE INVESTIGATION
On January 8 and 9, 2020, borings B1 through B25 were drilled at the subject property by Environmental Control Associates, Inc. of Aptos, California using a Geoprobe drill rig. The borings were located across the subject property in the area where previous sampling occurred. All soil borings were drilled to 4-foot bgs with four borings scheduled to be advanced to 15 feet bgs for collection of groundwater samples. Due to drill refusal, numerous borings were advanced beyond 4 feet bgs to attempt to collect groundwater samples with borings B-1, B-5, and B-12 identified as having groundwater. Additionally, boring B-16 was drilled only to two feet bgs, due to drill refusal.

The locations of the borings are presented in Figure 2.

Prior to drilling, a drilling permit was obtained from San Mateo County Department of Environmental Health (SMCEH). A copy of the permit is included in Appendix A. Additionally, the boring locations were marked in white paint and Underground Service Alert was contacted a minimum of 48 hours prior to drilling. Additionally, a private utility company was also utilized to clear the borings.

Soil samples were logged for lithologic and environmental evaluation in general accordance with the Unified Soil Classification System. The subsurface soil observed to the total depth explored of 4 feet bgs during drilling activities consisted generally of clay in borings B-1 through B-7; interlayered clay, silts and, gravel in borings B-8 through B-17; and clay or silt underlain by sand in borings B-18 through B-24. It should be noted that in boring B-15, the one-foot sample appeared not to be soil, but a cementitious product. Groundwater was encountered between 5 and 8 feet bgs with some borings drilled below 8 feet bgs did not encounter groundwater.

A photoionization detector (PID) was used to field-screen the soil samples for possible petroleum hydrocarbon impact. No visual or olfactory evidence of petroleum hydrocarbon impact was noted, and all PID concentrations were below the detection limit of 1 part per million (ppm). At the completion of the drilling, the soil borings were backfilled with cement grout according to SMCEH guidelines. The boring logs are presented in Appendix B.

Borings B-1, B-5 and B-12 were advanced below 4-foot bgs to allow for the collection of a groundwater sample. At the completed depth, temporary well casing was installed in the open boring consisting of threaded 0.75-inch diameter, Schedule 40 PVC casing with 0.010-inch machine-slotted screen, and a threaded end cap at the bottom. The temporary well was used as a conduit for the collection of groundwater from the borings. Prior to groundwater sampling, the depth to groundwater in each of the temporary wells was measured from the top of the well casing. For boring B-5, the casing was left in overnight to allow groundwater to enter the boring.

New polyethylene tubing was lowered through the casing down to the groundwater and groundwater samples were collected using a ball valve, forcing groundwater upward to the Hisense – Subsurface - SSF, CA

surface. Groundwater was discharged from the tubing directly into new laboratory-supplied vials and bottles, allowing the discharge to flow gently down the inside of the sample containers with minimal turbulence. The containers were filled, capped, labeled, logged on a chain-of custody form, and placed in a chilled ice chest pending delivery to the laboratory for analysis. New tubing was used at each well.

Once a sample was collected, it was logged on a chain-of custody form, labeled, and placed into a chilled ice chest pending delivery to the analytical laboratory. The samples were delivered to the laboratory within 48-hours of collection. All groundwater samples collected were transported to SunStar Laboratories (SunStar), a State of California certified lab, under strict COC protocol.

At the completion of groundwater sampling, the temporary monitoring well casing was removed and the boring(s) abandoned with cement grout. Fieldwork for drilling and groundwater sampling activities were conducted in general accordance with the field procedures described in Appendix C.

3.0 LABORATORY ANALYSIS RESULTS AND DISCUSSION
The soil and groundwater samples were submitted for analysis to SunStar Laboratories, Inc. of Lake Forest, California, a State of California DHS-ELAP certified environmental analytical laboratory. A summary of the laboratory results for the soil and groundwater samples are presented in Tables 1 through 4 with analytical results and chain-of-custody records presented in Appendix D. All soil samples were analyzed for lead according to EPA Method 6010. Additionally, the one-foot soil samples from borings B-6, B-11, B-15, and B-25 were analyzed for the following:
• Total Petroleum Hydrocarbon - Speciation according to EPA Method 8015M. • Volatile Organic Compounds (VOCs) according to EPA Method 8260. • PAHs according to EPA Method 8270.
• CAM Metals (17 Metals) according to EPA Method 6010.
• Chlorinated Pesticides according to EPA Method 8081.
• Polychlorinated Biphenyls (PCBs) according to EPA Method 8082.

All groundwater samples were analyzed for the following:
• TPH‐S according to EPA Method 8015M.
• VOCs according to EPA Method 8260.
• CAM Metals (17 Metals) according to EPA Method 6010.

3.1 SOIL SAMPLE RESULTS
The following are the results of the soil analysis:
• Total Petroleum Hydrocarbons as Gasoline (TPH-G), TPH as Motor Oil (TPH-MO), VOCs, PAHs, Chlorinated Pesticides, and PCBs were not detected at or above the laboratory reporting limit in all of the soil samples.
• TPH as Diesel (TPH-D) was detected in two soil samples at concentrations of 12 and 14 milligrams per kilogram (mg/kg). The TPH-D concentration was compared to the residential Bay Area Regional Water Quality Control Board Environmental Screening Level (ESL-R) for TPHD of 260 mg/kg. Both soil sample concentrations were considerably below the ESL-R. • CAM Metals (CAM 17) were detected in each of the soil samples collected for CAM 17. All of the detected metal concentrations were found at what appears to be background concentrations, with the exception of lead. Elevated lead concentrations were found in Hisense – Subsurface - SSF, CA

numerous soil samples at concentrations above the ESL-R. Additionally, vanadium and arsenic were found at concentrations above the ESL-R. However, these concentrations appear to be background concentrations that do not warrant additional investigation.

The laboratory results indicate that total lead concentrations are elevated. Due to the elevated concentrations of lead, the results of the soil analyses were compared to California Code of Regulations Title 22 List of Inorganic, Persistent, and Bioaccumulative Toxic Substances and their soluble threshold limit concentrations (STLC) and total threshold limit concentrations (TTLC) values. One soil sample (B-15-1) had a total lead concentration greater than the TTLC of 1,000 mg/kg. To determine whether the soil represented by this sample is a State of California (non-RCRA waste) or a Federal RCRA Waste, a Toxicity Characteristic Leaching Potential (TCLP) was performed. The results of the testing indicated that the soluble lead concentration was above the TCLP criteria, therefore, the soil represented by this sample would be classified as a Federal RCRA hazardous waste upon excavation and classification as a waste material.

Total lead concentrations were then compared to the screening criteria of ten times the STLC of 5 milligrams per liter (mg/L). Numerous soil samples had total lead concentrations greater than the screening criteria of ten times the STLC but were below the TTLC. A waste extraction test (WET) was performed on those samples to determine their soluble lead concentration. Five of these soil samples (B-23-1, B-24-1, B-24-2, B-25-1, and B-25-2) had a soluble lead concentration greater than the STLC after a WET. To determine whether the soil represented by these soil sample is a non-RCRA waste or a Federal RCRA waste, a TCLP was performed. The results of the testing indicated that the soluble lead concentration were all below the TCLP criteria, therefore, the soil represented by these samples would be classified a State of California Non-RCRA waste upon excavation and classification as a waste material.

3.2 DISCUSSION
The contaminant of concern as identified in the analyses of the soil samples at the subject property is lead. Lead concentrations above the California Non-RCRA waste criteria upon excavation and classification as a waste material were found in soil samples B-23-1, B-24-1, B-24-2, B-25-1, and B-25-2. These elevated lead concentrations were found in borings B-23 through B-25 on the far western end of the subject property. The 4-foot samples collected in each of these borings did not have elevated lead concentrations, while the 2-foot sample collected in boring B23 did not have elevated lead concentrations. The soil identified as a Non-RCRA waste appears to be confined to the upper two feet on the far western portion of the subject property. Figure 3 depicts the area of lead-impacted Non-RCRA soil. PSI estimated the volume of Non-RCRA soil to be removed using a bulking factor of 1.2. The volume of Non-RCRA soil was estimated to be approximately 425 cubic yards.

Lead concentrations above the Federal RCRA Waste criteria upon excavation and classification as a waste material were found only in soil sample B-15-1. The 2 and 4-foot samples collected from this boring did not have elevated lead concentrations. The soil identified as a Federal RCRA waste appears to be confined to the upper one foot in this area of the subject property. Figure 3 depicts the area of lead-impacted Federal RCRA soil. PSI estimated the volume of Federal RCRA soil to be removed using a bulking factor of 1.2. The volume of Federal RCRA soil was estimated to be approximately 160 cubic yards.

Further investigation in the area of boring B-15 and borings B-23 through B-25 could reduce the volume of soil that would be considered to be a Federal RCRA or Non-RCRA hazardous waste. This is especially true in the area of B-15, as the one-foot sample with the elevated lead concentrations did not appear to be similar to the rest of the soil found across the subject property. There is the possibility that the Federal RCRA waste maybe confined to a small area localized around boring B15

3.3 GROUNDWATER SAMPLE RESULTS
The following are the results of the groundwater analysis:
• TPH-G and VOCs were not detected at or above the laboratory reporting limit in all of the groundwater samples.
• TPH-D was detected in two groundwater samples at concentrations of 0.089 and 0.14 milligrams per kilogram (mg/L). The TPH-D concentrations were compared to the ESL-R for TPH-D of 0.26 mg/L. Both sample concentrations were below the ESL-R. • TPH-MO was detected in two groundwater samples at concentrations of 0.59 and 0.3 mg/L.

TPH-MO does not have an ESL-R. The TPH-MO concentrations do not represent an environmental concern.
• Metals were detected in each of the groundwater samples with concentrations greater than the ESL-R. However, the sample results are believed to be elevated due to the sampling methodology of sampling from an open borehole. Additionally, as all 4-foot soil samples appeared to have background metal concentrations, there is no indication that the metal concentrations detected are due to a release at the subject property. The metal concentrations do not represent an environmental concern.

4.0 SUMMARY & CONCLUSIONS
The results of the testing completed in January 2020 are summarized below. • Soil samples were analyzed for TPH-S, VOCs, PAHs, chlorinated pesticides, PCBs, and metals. The only contaminant of concern was found to be lead. • Soluble lead concentrations were found to be above the STLC, but below the TCLP waste criteria in five soil samples. The soil represented by these samples would be classified as a State of California Non-RCRA waste upon excavation and classification as a waste material.

The soil identified as a Non-RCRA waste appears to be confined to the upper two feet on the far western portion of the subject property. PSI estimated the volume of Non-RCRA soil to be approximately 425 cubic yards.
• Total lead concentrations were found to be above the TTLC and the TCLP waste criteria in one soil sample (B-15-1). The soil represented by this sample would be classified a Federal RCRA waste upon excavation and classification as a waste material. The soil identified as a Federal RCRA waste appears to be confined to the upper one foot. PSI estimated the volume of Non-RCRA soil to be approximately 160 cubic yards. • PSI believes further investigation in the area of boring B-15 and borings B-23 through B-25 could reduce the volume of soil that would be considered to be a Federal RCRA or NonRCRA hazardous waste. This is especially true in the area of B-15, as the one-foot sample with the elevated lead concentrations did not appear to be similar to the rest of the soil found across the subject property.
• The groundwater samples were analyzed for VOCs, metals, and TPH-S. The results of the groundwater analyses did not represent an environmental concern.

It appears that this investigation has defined the lateral and vertical extent of lead impacted soil.

Additional sampling may reduce the volume of estimated soil that may need to be removed as hazardous waste.

SAMPLE PROTOCOL

FIELD PROCEDURES
I. SOIL BORINGS AND COLLECTION OF SOIL AND GROUNDWATER SAMPLES

1. Prior to the commencement of soil boring activities at the site, boring locations were marked on the ground with white paint. Underground Service Alert (USA) was contacted to identify underground utilities in the vicinity of the soil borings.

2. A State of California-licensed drilling company conducted soil boring and sampling activities. The soil borings were advanced using the Geoprobe direct push method. Flush-threaded rods with a stainless steel sampler were advanced into the ground using a hydraulic percussion hammer.

3. Soil samples were collected using a 4-foot long, 2-inch inside diameter, macro-core stainless steel sampler. Soil samplers were washed between borings with Alconox soap followed by two deionized water rinses. The sampler was lined with clean acetate sleeves.

4. After the sampler was retrieved, the sleeves were extracted from the sampler without disturbing the sample.

5. Boring logs were prepared under the supervision of a California-Registered Geologist. Soil from each sample was described in accordance with Unified Soil Classification System by a PSI geologist and recorded on a field-boring log. The data recorded on the logs were based on examination of soil samples retrieved in the tubes, and drilling conditions observed in the field. Boring logs include information regarding the location of each boring, geologic descriptions of materials encountered, occurrence of groundwater and photoionization detector (PID) measurements of the soil samples collected (if applicable).

6. Groundwater samples were collected from the borings using disposable polyethylene tubing lowered through either the drill rods or through 1-inch diameter, slotted PVC casing.

7. Groundwater samples were collected into preserved containers using positive displacement and a check valve in the tubing.

8. Following groundwater sample collection, the samples were labeled, logged on a chain-of-custody record, placed in an ice-chilled cooler and transported to the environmental laboratory for analysis.

Sample containers and preservatives were utilized as instructed by the analytical laboratory. All transportation and handling of the groundwater samples followed chain-of-custody protocol.

II FIELD DOCUMENTATION OF SAMPLING PROCEDURES
The following outline describes the procedures followed by PSI for proper sampling documentation.

1. Sampling procedures were documented in field notes that will contain:

1. Sample collection procedures

2. Date and time of collection

3. Date of shipping

4. Sample collection location

5. Sample identification number(s)

6. Intended analysis

7. Quality control samples

8. Sample preservation

9. Name of sampler

10. Any pertinent observations

2. Samples were labeled with the following information:

1. Sample number

2. Well number

3. Date and time sample was collected

4. Sampler's name

5. Sample preservatives (if required)

6. Project Number

3. The following is the sample designation system for the site:

For Borings, the samples were labeled B-(Boring Number)-(Depth) (i.e. a sample collected from boring 4 at 5 feet would be B-4-5’)

4. Handling of the samples was recorded on a chain of custody form, which included:

1. Site name

2. Signature of collector

3. Date and time of collection

4. Sample identification number

5. Number of containers in sample set

6. Description of sample and container

7. Name and signature of persons, and the companies or agencies they represent, who are involved in the chain of possession

8. Inclusive dates and times of possession

9. Analyses to be completed

Notes and Definitions
S-MS Surrogate recovery outside of acceptance window confirmed as matrix effect by analysis of MS/MSD on this sample.

SGEL Sample extract was cleaned up with silica gel prior to analysis.

RE-01 Sample contained analytes with concentrations above calibration limits and was rerun at a dilution.

R-07 Reporting limit for this compound(s) has been raised to account for dilution necessary due to high levels of interfering compound(s) and/or matrix affect.

QM-13 Spike recovery for this analyte was bias high in the LCS and/or MS/MSD. Instrument blank, method blank and all samples were ND.

No negative impact on data is expected.

QM-06 Due to noted non-homogeneity of the QC sample matrix, the MS/MSD did not provide reliable results for accuracy and precision.

Sample results for the QC batch were accepted based on LCS/LCSD percent recoveries and RPD values.

QM-05 The spike recovery was outside acceptance limits for the MS and/or MSD due to possible matrix interference. The LCS was within acceptance criteria. The data is acceptable as no negative impact on data is expected.

QM-01 The % recovery is outside of established control limits due to matrix interference and/or sample dilution due to matrix effect. The batch was accepted based on acceptable LCS recovery.

C-06 Presence of analyte in sample suspected as common laboratory contaminant, which was also found in the method blank.

B-03 Analyte present in blank due to being a common laboratory contaminant.
