Executive Summary
Forensic Analytical Consulting Services (FACS), on behalf of Hal Hays Construction Inc., (Client)
conducted a Limited Site Investigation at Cal Water station 49-02 located at 3333 Stockdale Hwy., Bakersfield, CA 93309 (Site). The assessment was performed on March 4, 2019. FACS’s assessment was conducted in general compliance with the Above Storage Tank (AST) Bakersfield’s permit guidelines
and with the oversight of Shane Gardner the Hazardous Materials Specialist for the Bakersfield Fire Department.
Prior to implementing any intrusive activities at the Site, on February 28, 2019, FACS contacted the Bakersfield Fire Department. Mr. Shane Gardner, the Hazardous Materials Specialist for the Bakersfield Fire Department had overseen the removal of the AST that was completed by MD Concrete Cutting and
Demolition on February 28, 2019 (Permit No. 19-10000105). As part of the AST removal activities, soil sampling in the vicinity of the former AST was required.
On March 4, 2019, FACS advanced one soil boring using a hand auger to a depth of two feet below surface grade (bgs). The soil sample did not exhibit VOCs and TPH gasoline concentrations above the laboratory method reporting limits. TPH diesel, and motor oil reported concentrations at 24 milligrams per kilograms (mg/Kg) and 41 mg/Kg, respectively. Metals detected were barium (125 mg/Kg), cadmium (0.64 mg/Kg), chromium (12.0 mg/Kg) cobalt (8.32 mg/Kg), copper (10.6 mg/Kg), lead (10.3 mg/Kg), nickel (7.18 mg/Kg), vanadium (37.0 mg/Kg), and zinc (48.4 mg/Kg). A summary of the analysis results for TPH and detected metals are represented in Tables 1 and 2, respectively. FACS compared the reported concentrations to the Regional Screening Levels, Resident Soil (RSL). The reported
concentrations were below the applicable RSL.
The objective of the investigation was to evaluate the presence of TPH, VOCs, and metals, above
relevant laboratory reporting limits in association with the former operations of the AST. Additional site investigation activities associated with the AST removal are not recommended at this time.
If concrete, soils, or groundwater located on the site are to be disturbed during future excavations or construction activities, affected soil or groundwater encountered should be properly characterized, treated, and/or disposed in accordance with applicable local, state or federal regulations.

Introduction
Forensic Analytical Consulting Services (FACS), on behalf of Hal Hays Construction Inc., (Client) conducted a Limited Site Investigation at Cal Water station 49-02 located at 3333 Stockdale Hwy., Bakersfield, CA 93309 (Site). The Site location map is included as Figure 1. The assessment was
performed on March 4, 2019. This report contains the findings and recommendations from our investigation. FACS’s assessment was conducted in general compliance with the Above Storage Tank (AST) Bakersfield’s permit guidelines and with the oversight of Shane Gardner the Hazardous Materials
Specialist for the Bakersfield Fire Department.
Scope of Work
The objective of the investigation was to evaluate the presence of total petroleum hydrocarbons (TPH), volatile organic compounds (VOCs), and metals, above relevant laboratory reporting limits in association with the former operations of the AST.
Field Activities
Pre-Field Activities
Prior to implementing any intrusive activities at the Site, on February 28, 2019, FACS contacted the Bakersfield Fire Department. Mr. Shane Gardner, the Hazardous Materials Specialist for the Bakersfield
Fire Department had overseen the removal of the AST that was completed by MD Concrete Cutting and Demolition on February 28, 2019 (Permit No. 19-10000105). As part of the AST removal activities, soil sampling in the vicinity of the former AST was required.
Soil Borings
On March 4, 2019, FACS advanced one soil boring using a hand auger to a depth of two feet below surface grade (bgs). The sample location was selected downgradient to the former AST. The sample
location is presented as Figure 2.
In addition, the soil samples were field screened using sensory methods and a calibrated photoionization
detector (PID) to detect the presence of total VOCs. No odors were detected in the soil samples. Soil PID readings did not exceed ambient air readings, observed at 0.0 parts per million by volume (ppmv).
Soil Sampling
FACS’s soil sampling program involved collecting one soil sample from the bottom of the boring at two
feet bgs. The soil sample was collected and placed in laboratory prepared glass jar and placed on ice in a cooler. The sample cooler and completed chain-of-custody form was relinquished to Enthalpy Analytical Laboratory, in Orange, California for standard turnaround time using a courier service.
Laboratory Analytical Methods
The soil sample was analyzed for VOCs by United States Environmental Protection Agency (EPA) Method 8260B, California Administrative Metals (CAM) 17 metals by EPA Method 6010B, and TPH by EPA Method 8015M.
Laboratory results are summarized in Tables 1 and 2. The executed chain-of-custody form and laboratory data sheets are provided in Appendix A.

Data Evaluation
Soil Samples The soil sample did not exhibit VOCs and TPH gasoline concentrations above the laboratory method
reporting limits. TPH diesel, and motor oil reported concentrations at 24 milligrams per kilograms (mg/Kg) and 41 mg/Kg, respectively. Metals detected were barium (125 mg/Kg), cadmium (0.64 mg/Kg), chromium (12.0 mg/Kg) cobalt (8.32 mg/Kg), copper (10.6 mg/Kg), lead (10.3 mg/Kg), nickel (7.18
mg/Kg), vanadium (37.0 mg/Kg), and zinc (48.4 mg/Kg). A summary of the analysis results for TPH and detected metals are represented in Tables 1 and 2, respectively.
FACS compared the reported concentrations to the Regional Screening Levels, Resident Soil (RSL). The reported concentrations were below the applicable RSL. Findings and Recommendations
The findings and recommendations of this investigation are as follows:
• Based on the analytical results, the Site appears to have been affected with a release of
TPH diesel, motor oil, and select metals.
• The reported concentrations were below the applicable RSL.
• The objective of the investigation was to evaluate the presence of TPH, VOCs, and metals, above relevant laboratory reporting limits in association with the former operations of the AST. Additional site investigation activities associated with the AST removal are not recommended at this time.
• If concrete, soils, or groundwater located on the site are to be disturbed during future excavations or construction activities, affected soil or groundwater encountered should be properly characterized, treated, and/or disposed in accordance with applicable local, state or federal regulations.
Limitations
This investigation is limited to the conditions and practices observed and information made available to
FACS. The methods, conclusions and recommendations provided are based on FACS’s judgment, expertise, and the standard of practice for professional service in the industry. They are subject to the limitations and variability inherent in the methodology employed. As with all environmental investigations,
this investigation is limited to the defined scope and does not purport to set forth all hazards nor indicate that other hazards do not exist.

Analytical Results Report
Data Qualifiers and Definitions
Qualifiers
A See Report Comments.
B Analyte was present in an associated method blank.
B1 Analyte was present in a sample and associated method blank greater than MDL but less than RDL.
BQ1 No valid test replicates. Sample Toxicity is possible. Best result was reported.
BQ2 No valid test replicates.
BQ3 No valid test replicates. Final DO is less than 1.0 mg/L. Result may be greater.
BQ4 Minor Dissolved Oxygen loss was observed in the blank water check, however, the LCS was within criteria, validating the batch.
BQ5 Minor Dissolved Oxygen loss was observed in the blank water check.
C Possible laboratory contamination.
D RPD was not within control limits. The sample data was reported without further clarification.
D1 Lesser amount of sample was used due to insufficient amount of sample supplied.
D2 Reporting limit is elevated due to sample matrix. Target analyte was not detected above the elevated reporting limit.
D3 Insufficient sample was supplied for TCLP. Client was notified. TCLP was performed per the Client’s instructions.
DW Sample result is calculated on a dry weigh basis.
E Concentration is estimated because it exceeds the quantification limits of the method.
I The sample was read outside of the method required incubation period.
IR Inconclusive Result. Legionella is present, however, there is possible non-specific agglutination preventing specific identification.
J Reported value is estimated
L The laboratory control sample (LCS) or laboratory control sample duplicate (LCSD) was out of control limits. Associated sample
data was reported with qualifier.
L2 LCS did not meet recovery criteria, however, the MS and/or MSD met LCS recovery criteria, validating the batch.
M The matrix spike (MS) or matrix spike duplicate (MSD) was not within control limits due to matrix interference. The associated
LCS and/or LCSD was within control limits and the sample data was reported without further clarification.
M1 The matrix spike (MS) or matrix spike duplicate (MSD) is not within control limits due to matrix interference.
M2 The matrix spike (MS) or matrix spike duplicate (MSD) was not within control limits. The associated LCS and/or LCSD was not
within control limits. Sample result is estimated.
N1 Sample chromatography does not match the specified TPH standard pattern.
NC The analyte concentration in the sample exceeded the spike level by a factor of four or greater, spike recovery and limits do not
apply.
P Sample was received without proper preservation according to EPA guidelines.
P1 Temperature of sample storage refrigerator was out of acceptance limits.
P2 The sample was preserved within 24 hours of collection in accordance with EPA 218.6.
P3 Per Client request, sample was composited for volatile analysis. Sample compositing for volatile analysis is not recommended
due to potential loss of target analytes. Results may be biased low.
Q1 Analyte Calibration Verification exceeds criteria. The result is estimated.
Q2 Analyte calibration was not verified and the result was estimated.
Q3 Analyte initial calibration was not available or exceeds criteria. The result was estimated.
S The surrogate recovery was out of control limits due to matrix interference. The associated method blank surrogate recovery
was within control limits and the sample data was reported without further clarification.
S1 The associated surrogate recovery was out of control limits; result is estimated.
S2 The surrogate was diluted out due to the presence of high concentrations of target and/or non-target compounds. Surrogate
recoveries in the associated batch QC met recovery criteria.
S3 Internal Standard did not meet recovery limits. Analyte concentration is estimated.
T Sample was extracted/analyzed past the holding time.
T1 Reanalysis was reported past hold time due to failing replicates in the original analysis (BOD only).
T2 Sample was analyzed ASAP but received and analyzed past the 15 minute holding time.
T3 Sample received and analyzed out of hold time per client’s request.
T4 Sample was analyzed out of hold time per client’s request.
T5 Reanalysis was reported past hold time. The original analysis was within hold time, but not reportable.
T6 Hold time is indeterminable due to unspecified sampling time.
T7 Sample was analyzed past hold time due to insufficient time remaining at time of receipt.
