Qualifiers Definition
* See applicable analysis comment.
< Less than the indicated value.
> Greater than the indicated value.
1 Surrogate compound recovery was out of control due to a required sample dilution. Therefore, the sample data was reported without further clarification.
2 Surrogate compound recovery was out of control due to matrix interference. The associated method blank surrogate spike compound was in control and, therefore, the sample data was reported without further clarification. 3 Recovery of the Matrix Spike (MS) or Matrix Spike Duplicate (MSD) compound was out of control due to suspected matrix interference. The associated LCS recovery was in control.
4 The MS/MSD RPD was out of control due to suspected matrix interference. 5 The PDS/PDSD or PES/PESD associated with this batch of samples was out of control due to suspected matrix interference. 6 Surrogate recovery below the acceptance limit.
7 Surrogate recovery above the acceptance limit.

B Analyte was present in the associated method blank.

BU Sample analyzed after holding time expired.

BV Sample received after holding time expired.

CI See case narrative.

E Concentration exceeds the calibration range.

ET Sample was extracted past end of recommended max. holding time.

HD The chromatographic pattern was inconsistent with the profile of the reference fuel standard.

HDH The sample chromatographic pattern for TPH matches the chromatographic pattern of the specified standard but heavier hydrocarbons were also present (or detected).

HDL The sample chromatographic pattern for TPH matches the chromatographic pattern of the specified standard but lighter hydrocarbons were also present (or detected).

J Analyte was detected at a concentration below the reporting limit and above the laboratory method detection limit. Reported value is estimated.

JA Analyte positively identified but quantitation is an estimate.

ME LCS Recovery Percentage is within Marginal Exceedance (ME) Control Limit range (+/- 4 SD from the mean).

ND Parameter not detected at the indicated reporting limit.

Q Spike recovery and RPD control limits do not apply resulting from the parameter concentration in the sample exceeding the spike concentration by a factor of four or greater.

SG The sample extract was subjected to Silica Gel treatment prior to analysis.

X % Recovery and/or RPD out-of-range.

Z Analyte presence was not confirmed by second column or GC/MS analysis.

Solid - Unless otherwise indicated, solid sample data is reported on a wet weight basis, not corrected for % moisture. All QC results are reported on a wet weight basis.

Any parameter identified in 40CFR Part 136.3 Table II that is designated as "analyze immediately" with a holding time of <= 15 minutes (40CFR-136.3 Table II, footnote 4), is considered a "field" test and the reported results will be qualified as being received outside of the stated holding time unless received at the laboratory within 15 minutes of the collection time.

A calculated total result (Example: Total Pesticides) is the summation of each component concentration and/or, if "J" flags are reported, estimated concentration. Component concentrations showing not detected (ND) are summed into the calculated total result as zero concentrations.

Qualifiers Definition
* See applicable analysis comment.
< Less than the indicated value.
> Greater than the indicated value.
1 Surrogate compound recovery was out of control due to a required sample dilution. Therefore, the sample data was reported without further clarification.
2 Surrogate compound recovery was out of control due to matrix interference. The associated method blank surrogate spike compound was in control and, therefore, the sample data was reported without further clarification. 3 Recovery of the Matrix Spike (MS) or Matrix Spike Duplicate (MSD) compound was out of control due to suspected matrix interference. The associated LCS recovery was in control.
4 The MS/MSD RPD was out of control due to suspected matrix interference. 5 The PDS/PDSD or PES/PESD associated with this batch of samples was out of control due to suspected matrix interference. 6 Surrogate recovery below the acceptance limit.
7 Surrogate recovery above the acceptance limit.

B Analyte was present in the associated method blank.

BU Sample analyzed after holding time expired.

BV Sample received after holding time expired.

CI See case narrative.

E Concentration exceeds the calibration range.

ET Sample was extracted past end of recommended max. holding time.

HD The chromatographic pattern was inconsistent with the profile of the reference fuel standard.

HDH The sample chromatographic pattern for TPH matches the chromatographic pattern of the specified standard but heavier hydrocarbons were also present (or detected).

HDL The sample chromatographic pattern for TPH matches the chromatographic pattern of the specified standard but lighter hydrocarbons were also present (or detected).

J Analyte was detected at a concentration below the reporting limit and above the laboratory method detection limit. Reported value is estimated.

JA Analyte positively identified but quantitation is an estimate.

ME LCS Recovery Percentage is within Marginal Exceedance (ME) Control Limit range (+/- 4 SD from the mean).

ND Parameter not detected at the indicated reporting limit.

Q Spike recovery and RPD control limits do not apply resulting from the parameter concentration in the sample exceeding the spike concentration by a factor of four or greater.

SG The sample extract was subjected to Silica Gel treatment prior to analysis.

X % Recovery and/or RPD out-of-range.

Z Analyte presence was not confirmed by second column or GC/MS analysis.

Solid - Unless otherwise indicated, solid sample data is reported on a wet weight basis, not corrected for % moisture. All QC results are reported on a wet weight basis.

Any parameter identified in 40CFR Part 136.3 Table II that is designated as "analyze immediately" with a holding time of <= 15 minutes (40CFR-136.3 Table II, footnote 4), is considered a "field" test and the reported results will be qualified as being received outside of the stated holding time unless received at the laboratory within 15 minutes of the collection time.

A calculated total result (Example: Total Pesticides) is the summation of each component concentration and/or, if "J" flags are reported, estimated concentration. Component concentrations showing not detected (ND) are summed into the calculated total result as zero concentrations.

Samples were received under Chain-of-Custody (COC) on 07/13/16. They were assigned to Work Order 16-07-0873.

Unless otherwise noted on the Sample Receiving forms all samples were received in good condition and within the recommended EPA temperature criteria for the methods noted on the COC. The COC and Sample Receiving Documents are integral elements of the analytical report and are presented at the back of the report.

Holding Times:

All samples were analyzed within prescribed holding times (HT) and/or in accordance with the Calscience Sample Acceptance Policy unless otherwise noted in the analytical report and/or comprehensive case narrative, if required.

Any parameter identified in 40CFR Part 136.3 Table II that is designated as "analyze immediately" with a holding time of <= 15 minutes (40CFR-136.3 Table II, footnote 4), is considered a "field" test and the reported results will be qualified as being received outside of the stated holding time unless received at the laboratory within 15 minutes of the collection time.

Quality Control:

All quality control parameters (QC) were within established control limits except where noted in the QC summary forms or described further within this report.

Subcontractor Information:

Unless otherwise noted below (or on the subcontract form), no samples were subcontracted.

Additional Comments:

Air - Sorbent-extracted air methods (EPA TO-4A, EPA TO-10, EPA TO-13A, EPA TO-17): Analytical results are converted from mass/sample basis to mass/volume basis using client-supplied air volumes.

Solid - Unless otherwise indicated, solid sample data is reported on a wet weight basis, not corrected for % moisture. All QC results are always reported on a wet weight basis.

CASE NARRATIVE
Eurofins Calscience Work Order 16-07-0873
EPA Method 6010B Total Metals:

Project Required Detection Limit (PRDL):

The PRDL’s were analyzed as required per the project QAPP. The low level calibration check performed post the sample batch is outside acceptable range for Arsenic and Thallium on 07/21/16 for soil samples.

The PRDL’s were analyzed as required per the project QAPP. The low level calibration check performed post the sample batch is outside acceptable range for Antimony on 07/22/16 for soil samples.

Table A: Matrix Spike / Matrix Spike Duplicate outside acceptable limits EPA Method 6010B
Batch # Analytes(s)
160719S03 Antimony3,4, Barium3, Vanadium3and Zinc3
3: Recovery of the Matrix Spike (MS) or Matrix Spike Duplicate (MSD) compound was out of control due to suspected matrix interference. The associated LCS recovery was in control. 4: The MS/MSD RPD was out of control due to suspected matrix interference.

The LCS/LCSD recoveries for the associated sample batches are within acceptable control limits, therefore, the results have been released without any further action or qualification.

Qualifiers Definition
* See applicable analysis comment.
< Less than the indicated value.
> Greater than the indicated value.
1 Surrogate compound recovery was out of control due to a required sample dilution. Therefore, the sample data was reported without further clarification.
2 Surrogate compound recovery was out of control due to matrix interference. The associated method blank surrogate spike compound was in control and, therefore, the sample data was reported without further clarification. 3 Recovery of the Matrix Spike (MS) or Matrix Spike Duplicate (MSD) compound was out of control due to suspected matrix interference. The associated LCS recovery was in control.
4 The MS/MSD RPD was out of control due to suspected matrix interference. 5 The PDS/PDSD or PES/PESD associated with this batch of samples was out of control due to suspected matrix interference. 6 Surrogate recovery below the acceptance limit.
7 Surrogate recovery above the acceptance limit.

B Analyte was present in the associated method blank.

BU Sample analyzed after holding time expired.

BV Sample received after holding time expired.

CI See case narrative.

E Concentration exceeds the calibration range.

ET Sample was extracted past end of recommended max. holding time.

HD The chromatographic pattern was inconsistent with the profile of the reference fuel standard.

HDH The sample chromatographic pattern for TPH matches the chromatographic pattern of the specified standard but heavier hydrocarbons were also present (or detected).

HDL The sample chromatographic pattern for TPH matches the chromatographic pattern of the specified standard but lighter hydrocarbons were also present (or detected).

J Analyte was detected at a concentration below the reporting limit and above the laboratory method detection limit. Reported value is estimated.

JA Analyte positively identified but quantitation is an estimate.

ME LCS Recovery Percentage is within Marginal Exceedance (ME) Control Limit range (+/- 4 SD from the mean).

ND Parameter not detected at the indicated reporting limit.

Q Spike recovery and RPD control limits do not apply resulting from the parameter concentration in the sample exceeding the spike concentration by a factor of four or greater.

SG The sample extract was subjected to Silica Gel treatment prior to analysis.

X % Recovery and/or RPD out-of-range.

Z Analyte presence was not confirmed by second column or GC/MS analysis.

Solid - Unless otherwise indicated, solid sample data is reported on a wet weight basis, not corrected for % moisture. All QC results are reported on a wet weight basis.

Any parameter identified in 40CFR Part 136.3 Table II that is designated as "analyze immediately" with a holding time of <= 15 minutes (40CFR-136.3 Table II, footnote 4), is considered a "field" test and the reported results will be qualified as being received outside of the stated holding time unless received at the laboratory within 15 minutes of the collection time.

A calculated total result (Example: Total Pesticides) is the summation of each component concentration and/or, if "J" flags are reported, estimated concentration. Component concentrations showing not detected (ND) are summed into the calculated total result as zero concentrations.

Dear Ms. Crystal:
of Building 99 at the
BFGoodrich Aerostructure[l'B___EG)JFacility in Chula Vista, California, during June and July 1999. The wells were installed for use during an aquifer test. Base,: on initial results. one additional pumping weU 2 additional observation ·;.·ell(!QYI.=3-,md.-4)rwere installed at the A check foljthe f permit fee for three additior.al wells ($450) is included with this> well log submittal. Drill cuttings from the six well borings were placed in rcll-off bins and were properly dispcsed of by Pacific Treatment Environmental Services (PTES). Wash water generated during well 'nstallation was transferred to the onsite pretreatment facility by BFG personneL
[n accordance with the Site c'\s><:S.<ment and Mitiption Manual (revised 1999), copies of a site plan showing the well locarions, we!l logs and laboratory analy1iQJ report are provided._,Lithologic.logs were not for wei! b01ings OW-3 and OW--'1 because in close proxin!J!Y (within 20 feet) of well completion diagrams for wells OW-3 and OW-4 are provided in Figure 3. If you have: any questions, please gi•.'e tlS a -:alL Very truly yours,

Two deep test boringS1IJ.B-:;:!'ancrDB=3) and one deep installed at the BFGoodrich Aerostructures (BFG) Facility in Chula Vista, California, during November and December 1998. The borings and wells were installed to monitor general water quality (TDS and general minerals). The original permit application dated October 20,1998, which included one boring, was approved by the DEH on October 29, 1998. URS Greiner Woodward Clyde (1JR.SGWC) submitted two modifications to the permit for one additional well and one additional boring on November 4 and 18, 1998.

In accordance with the Site Assessment and Mitigation Manual (revised 1999), copies of a site plan showing the boring and well locations, well logs, 3nd laboratory analy1ical reports are provided. Drill cuttings from the three boreholes were placed in roll-off bins and were properly disposed of by Pacific Treatment Environmental Services (PTES). Wash water generated during well installation was transferred to the onsite pretreatment facility by BFG personnel. If you have any questions, please give us a cal!.

Assessor’s Parcel No. 567-022-30-00
Permit No. LMWP-004690
Dear Well Permit Clerk:

Haley & Aldrich, Inc., is submitting this well destruction report to the County of San Diego Department of Environmental Health (DEH) for three monitoring wells (DB-2, DB-4, and DB-5) and two pressure transducers (OW-1 and OW-2) on the property associated with Assessor’s Parcel Number 567-022-30- 00, located at 390 Bay Boulevard at the Rohr, Inc., a Collins Aerospace Company, facility located in Chula Vista, California (Site; Figure 1). The wells and transducers were destroyed under Permit No. LMWP004690, approved by the DEH on September 28, 2020.

Cascade Drilling, Inc., a C-57 licensed drilling company located in Upland, California, completed the destruction of the monitoring wells and pressure transducers. Wells DB-2 and DB-5 and the pressure transducers OW-1 and OW-2 were destroyed on October 19 and October 20, 2020. Well DB-5 was destroyed on November 16 and 17, 2020.

Prior to destruction, the total depth of each well was measured to identify whether the well was free of obstructions. No obstructions were observed. The monitoring wells were abandoned by pressure grouting. Each boring was backfilled from the bottom up to within approximately 5 feet below the ground surface (bgs) with cement-bentonite grout (with 5 percent bentonite by weight) mixed at a ratio of approximately 100 pounds of solids to 35 to 40 gallons of water and then pumped through a tremie pipe. The grout was placed within the screen interval and held at 30 pounds per square inch of pressure for 20 minutes.

A hollow-stem auger rig was used to overdrill the two wells with polyvinyl chloride casings (DB-2 and DB-4) so that the casings could be removed. An 8.5-inch-diameter cutting head was used to destroy and remove the upper 5 feet of casing. The upper 5 feet of well DB-5 was removed by excavating around it County of San Diego Department of Environmental Health
January 6, 2021

to approximately 4 feet bgs and cutting the steel casing off at 5 feet bgs using an arc welder. The upper 5 feet of the DB-2 and DB-5 boreholes were filled with bentonite chips hydrated during placement. The surface at each location was finished in concrete. Table I provides a backfill material summary for each well.

The traffic covers for the pressure transducers (OW-1 and OW-2) were removed and filled with concrete to the surface grade to abandon them. The traffic covers for monitoring wells OW-3 and OW-4, which remain on Site, were replaced in accordance with DEH guidelines. If you have any questions regarding the well destructions, please contact us.

Sincerely yours,
HALEY & ALDRICH, INC.
