Dear Mr. Dal Soglio:

Rockwell Solutions, Inc. oversaw high vacuum dual phase extraction (HVDPE) activities for the above-
referenced release from December 2023 through February 2024. Seven groundwater extraction/
monitoring wells were installed in November 2023 and eighteen monitoring wells were sampled prior to
beginning remediation activities. The results of the installation and groundwater sampling were
documented in a “Monitoring Well Installation and Groundwater Monitoring Report” dated November
21, 2023.

CalClean Event
From December 12, 2023, to February 27, 2024, CalClean conducted high vacuum dual phase extraction
(HVDPE) at fourteen monitoring wells in the MTBE plume. The HVDPE system extracted groundwater
and vapors from five monitoring wells at a time. Extraction wells were moved to treat different parts of
the plume during the eleven-week event. The following table shows how many weeks each well was
treated:

The HVDPE system ran continuously during the 75-day event and extracted approximately 163,590
gallons of groundwater. The extracted groundwater was treated and discharged into the sewer system
through an onsite sewer cleanout with authorization from the South Valley Water Reclamation facility.

Vapor Extraction
The HVDPE system removed soil vapors in conjunction with the groundwater extraction. Vapor
readings were collected from the field analyzer in the system three times a day and vapor samples were
collected on a weekly basis to monitor hydrocarbon removal. Vapors were destroyed by a thermal
oxidizer unit in the truck. CalClean has prepared an extraction report which calculates, based on the daily
readings and weekly vapor samples, that approximately 6,755 pounds of hydrocarbons were removed
during the 75-day event. Vapor analyses indicated 73% and 86% reductions in benzene and TPH vapors,
respectively, from the initial to the final air samples. The CalClean report is attached.

Mid-Remediation Event Groundwater Monitoring
On January 5, 2024, groundwater samples were collected from MW-6 and MW-17. On January 19, 2024,
groundwater samples were collected from MW-7, MW-18, and MW-21. Each groundwater sample was
immediately placed on ice and retained under chain-of-custody documentation until relinquished to the
laboratory for analysis of MBTEXN and TPH-GRO using EPA Method 8260 and TPH-DRO using EPA
Method 8015.

The groundwater sample results collected during the extraction showed reductions in hydrocarbon
concentrations. The January 2024 sample results are included in Table 1 and the analytical reports are
attached.

Post-Remediation Event Groundwater Monitoring
On April 4-5, 2024, groundwater samples were collected from the same eighteen monitoring wells that
were sampled prior to the extraction event. Groundwater measurements and samples were collected from
each well using a disposable bailer. Each groundwater sample was immediately placed on ice and
retained under chain-of-custody documentation until relinquished to the laboratory.

Groundwater samples were submitted for analysis of MBTEXN and TPH-GRO using EPA Method 8260
and TPH-DRO using EPA Method 8015. The results are included in Table 1 and the analytical reports
are attached.

Results
MTBE concentrations decreased an average of 52% in the four most contaminated monitoring wells at the
center of the plume (MW-1, MW-6, MW-17, and MW-21). Figures 1 and 2 are isoconcentration maps
showing the approximate areas of MTBE contamination for the November 2023 and April 2024 sampling
events, respectively. A comparison of the isoconcentration maps from November 2023 to April 2024
show significant reduction in the center of the contaminant plume and some shrinkage of the overall
plume.

Conclusions and Recommendations
The extraction event appears to have been successful in reducing contaminant concentrations. Rockwell
Solutions recommends a second extraction event that focuses mainly on the wells at the center of the
plume.

Analytical test results meet all requirements of the associated regulatory program listed on the Accreditation/Certification Summary
Page unless otherwise noted under the individual analysis.Data qualifiers are applied to indicate exceptions.Noncompliant
quality control (QC)is further explained in narrative comments.
Matrix QC may not be reported if insufficient sample or site-specific QC samples were not submitted.In these situations,to
demonstrate precision and accuracy at a batch level,a LCS/LCSD may be performed,unless otherwise specified in the
method.
Surrogate and/or isotope dilution analyte recoveries (if applicable)which are outside of the QC window are confirmed
unless attributed to a dilution or otherwise noted in the narrative.
Regulated compliance samples (e.g.SDWA,NPDES)must comply with the associated agency requirements/permits.

Analytical test results meet all requirements of the associated regulatory program listed on the Accreditation/Certification Summary
Page unless otherwise noted under the individual analysis.Data qualifiers are applied to indicate exceptions.Noncompliant
quality control (QC)is further explained in narrative comments.
Matrix QC may not be reported if insufficient sample or site-specific QC samples were not submitted.In these situations,to
demonstrate precision and accuracy at a batch level,a LCS/LCSD may be performed,unless otherwise specified in the
method.
Surrogate and/or isotope dilution analyte recoveries (if applicable)which are outside of the QC window are confirmed
unless attributed to a dilution or otherwise noted in the narrative.
Regulated compliance samples (e.g.SDWA,NPDES)must comply with the associated agency requirements/permits.

Job Narrative
570-168479-1
Analytical test results meet all requirements of the associated regulatory program listed on the Accreditation/Certification Summary
Page unless otherwise noted under the individual analysis.Data qualifiers are applied to indicate exceptions.Noncompliant
quality control (QC)is further explained in narrative comments.
Matrix QC may not be reported if insufficient sample or site-specific QC samples were not submitted.In these situations,to
demonstrate precision and accuracy at a batch level,a LCS/LCSD may be performed,unless otherwise specified in the
method.
Surrogate and/or isotope dilution analyte recoveries (if applicable)which are outside of the QC window are confirmed
unless attributed to a dilution or otherwise noted in the narrative.
Regulated compliance samples (e.g.SDWA,NPDES)must comply with the associated agency requirements/permits.
COMMENT
Please note that one or more samples in the following analytical report have exceeded the laboratory recommended holding time
for tedlar bags (3 days).As per client-specific program requirements,associated qualifiers concerning holding time have been
removed.
Receipt
The sample was received on 1/17/2024 7:48 PM.Unless otherwise noted below,the sample arrived in good condition,and,where
required,properly preserved and on ice.The temperature of the cooler at receipt time was 22.0°C
Air -GC/MS VOA
Method TO15_PF:Surrogate recovery for the following sample was outside control limits:TOTAL INLET (570-168479-1).
Evidence of matrix interference is present;therefore,re-extraction and/or re-analysis was not performed.
Method TO15_PF:The continuing calibration verification (CCV)associated with batch 570-402433 recovered above the upper
control limit for tert-Butyl alcohol (TBA).The samples associated with this CCV were non-detects for the affected analytes;
therefore,the data have been reported.
No additional analytical or quality issues were noted,other than those described above or in the Definitions/Glossary page.
Air -GC VOA
No additional analytical or quality issues were noted,other than those described above or in the Definitions/Glossary page.
