Thank you for allowing Plantation Pipe Line Company's representatives (CH2M HILL, now part of
Jacobs Engineering Group Inc.) to conduct semiannual soil vapor monitoring activities on your property in
October 2018. The purpose of this letter is to provide a summary of the monitoring activities conducted on
your property, along with a summary of the analytical results.
October 2018 Monitoring Activities
On October 3, 2018, CH2M (now Jacobs) sent you an email requesting access to your property to collect
semiannual samples from soil vapor monitoring points SV-5R and SV-14R (see attached figure). On
October 17, 2018, leak checks were conducted on each soil vapor monitoring point prior to collecting a
vapor sample. Both soil vapor monitoring points passed the leak check and were purged with an electric
sampling pump prior to sample collection. Soil vapor samples were then collected using vacuum canisters
and sampling syringes with charcoal tubes. The samples were submitted to ALS Environmental (ALS) in
Simi Valley, California for analysis of benzene, toluene, ethylbenzene, xylenes (BTEX), naphthalene, and
2-methylnaphthalene.
As previously discussed via email on October 18, 2018, it was determined that the connections on the
vacuum canister leaked while collecting the sample from soil vapor monitoring point SV-5R for the
analysis of BTEX. In the October 18, 2018 email, Jacobs requested access to your property to recollect
the vacuum canister sample from soil vapor monitoring point SV-5R. On October 19, 2018, a leak check
was conducted on monitoring point SV-5R prior to collecting a vapor sample. The soil vapor monitoring
point passed the leak check and was purged with an electric sampling pump prior to sample collection.
Soil vapor samples and duplicate samples were then collected using vacuum canisters. The samples
were submitted to ALS in Simi Valley, California for the analysis of BTEX.
Analytical Results
The analytical data from the October 17, 2018 and October 19, 2018 monitoring events are attached to
this letter and are summarized in Table 1. When reviewing the laboratory analytical report, please note
the sample identifications for your soil vapor monitoring points are SV-5R-101718, SV-5R-101918, and

SV-14R-101718. Duplicate samples were collected from soil vapor monitoring point SV-5R as part of a
standard practice to measure field and laboratory precision, as well as to provide an indication of the
comparability of the results. The duplicate sample identifications are SV-5RD-101718 and SV-5RD-
101918. Data from historical monitoring events are shown in Table 2.
The analytical results show that the samples collected in October 2018 were significantly lower than North
Carolina Department of Environmental Quality (NCDEQ) and United States Environmental Protection
Agency (USEPA) regulatory screening criteria, as shown in Table 1. The purpose of these soil gas criteria
is for "screening" site data to help identify areas, contaminants, and conditions that may require further
evaluation or attention.
Factors Influencing the Analytical Results
In general, soil vapor monitoring results are expected to vary over time due to several factors, including
seasonal temperature changes, changes in barometric pressure, changes in water table elevations,
changes in subsurface conditions due to precipitation prior to a monitoring event, changes in subsurface
conditions due to operating the remediation system, and variations in the contaminant source
concentrations. Also, because the original soil vapor monitoring points were replaced (SV-5 was replaced
by SV-5R in November 2012, and SV-14 was replaced by SV-14R in November 2012), they are currently
installed in slightly different locations compared to the original points. Furthermore, the changes in
concentrations observed to date are within the range of concentration variability anticipated due to the
factors described above.
An initial evaluation of the precipitation data, vacuum monitoring data, and analytical data to date
generally shows that during and following precipitation events positive pressure and elevated
concentrations are observed in SV-5R; during drier periods, vacuum influence and relatively lower
analytical concentrations are observed. This trend suggests that the soil vapor extraction (SVE) system is
positively influencing SV-5R and the surrounding area during periods of drier weather; however, during
periods of increased precipitation, positive pressure is noted, along with elevated concentrations. The
SVE system will continue to recover soil vapor from the vicinity of SV-5R, with optimal vapor recovery
during periods of drier weather.
Similar conditions regarding precipitation and vacuum and pressure readings have been observed at SV-
14R, although to a lesser extent, likely due to the proximity of SV-14R to the SVE well and potentially
more permeable soil near SV-14R.
Soil Vapor Monitoring Plan
The next semiannual monitoring event is currently planned for April 2019. Jacobs will contact you
separately to coordinate this monitoring event.
Thank you for your assistance and we apologize for any inconvenience this sampling program may
cause. Please feel free to contact me at 704.543.3285 or Jerry Aycock with Plantation at 770.751.4165 if
you have any questions about the monitoring results. The NCDEQ is an additional resource to discuss
aspects of the site and our monitoring activities. Ms. Trudy Beverly is the NCDEQ case manager and can
be contacted at 704.663.1699 concerning this site (NCDEQ Incident #88110).
Again, thank you for your cooperation.
Sincerely,
Mike Skeean, P.E.
Project Manager

1. Introduction
The purpose of this memorandum is to present the results of the data validation process for the soil vapor
samples collected at the Plantation Pipe Line Company (PPL) Poplar Tent Road. The samples were
collected in October 2018.
Samples were submitted to ALS Global in Simi Valley, California for the following analyses:
• T015 SIM Volatiles
• T017 Volatiles
These data were validated for compliance with the analytical method requirements. This process included
a review of these data to assess the accuracy, precision, and completeness based upon procedures
described in guidance documents such as the Environmental Protection Agency (EPA) National
Functional Guidelines for Organic Data Review (EPA 2017). The Quality assurance/quality control
(QA/QC) summary forms and data reports were reviewed and the resulting findings are documented
within each subsection that follows.
During the data validation, if QA/QC parameters were not within the acceptance limits, associated sample
results were appended with a primary qualifying flag that indicated a possible anomaly with these data.
The qualifying flags originated during the data review and validation processes. This qualification also
included the use of secondary sub -qualifier flags. The secondary qualifiers provide the reasoning behind
the assignment of a qualifier to these data. The definitions of the primary qualifiers are presented below.
2. Validation Flag Definitions
The following primary qualifiers were used to qualify the data:
[_]: Detected. The analyte was analyzed for and detected at the concentration shown.
[J]: Estimated. The analyte was present but the reported value may not be accurate or precise.
[U]: Undetected. The analyte was analyzed for but not detected above the method detection limit.
[UJ]: Detection limit estimated. The analyte was analyzed for but qualified as not detected; the
detection limit is estimated.
[R]: Rejected. The data are not useable.
[X]: Excluded. Data were not used due to another value being more appropriate.

3. Organic Parameters
3.1 Quality Control Review
The following list represents the QA/QC measures that were reviewed during the data quality evaluation
procedure for organic data:
• Holding Times — The holding times are evaluated to verify that samples were extracted and
analyzed within holding times.
• Blank samples — Method blank samples were provided for this project. Blank samples enable the
reviewer to determine if an analyte may be attributed to sampling or laboratory procedures, rather
than environmental contamination from site activities.
• Surrogate Recoveries — Surrogate Compounds are added to each sample and the recoveries are
used to monitor lab performance and possible matrix interference.
• Lab Control Sample (LCS) — These samples are a "controlled matrix", laboratory reagent water, in
which target compounds have been added prior to extraction/analysis. The recoveries serve as a
monitor of the overall performance of each step during the analysis, including sample preparation.
• Matrix Spike/Matrix Spike Duplicate (MS/MSD) Samples — Spike recovery is used to evaluate
potential matrix interferences, as well as accuracy. Precision information is also determined by
calculating the reproducibility between the recoveries of each spiked parameter.
• Field Duplicate Samples — These samples are collected to determine precision between a native
and its duplicate. This information can only be determined when target compounds are detected.
4. Volatile Organic Compound Analyses
The QA/QC parameters for VOC analyses by SW-846 8260B for all samples were within acceptable
control limits with the exceptions listed below. A brief overview of the data evaluation follows:
4.1 Holding Time
All holding time requirements were met.
4.2 Field Duplicates
Duplicate field samples were collected and submitted to the laboratory for analysis. There are two
conditions under which the native and field duplicate are deemed outside acceptance criteria. For
condition one, if a result for the native and field duplicate are less than five times the reporting limit, the
two results must be within one times the reporting limit to meet acceptance criteria. In condition two, if the
result is greater than five times the reporting limit, the two results must agree to within 20 percent relative
percent difference to meet acceptance criteria. All acceptance criteria were met.
4.3 Recoveries — Surrogates, MS/MSD, LCS/LCSD
Surrogates and LCS/LCSD recoveries all met acceptance criteria. A MS/MSD set was not collected for
this event.
4.4 Analytical Blanks
No target analytes were detected in the blanks.

Data Validation Summary - Plantation Pipe Line Poplar Tent Road Site JACOBSW
5. PARCC
Precision is defined as the agreement between duplicate results, and was estimated by comparing
duplicate MS recoveries, and field duplicate sample results. The precision between the native and field
duplicate sample results for all analyses were within acceptable criteria indicating that the sample matrix
did not interfere with the overall analytical process.
Accuracy is a measure of the agreement between an experimental determination and the true value of
the parameter. In the case of VOC analysis, each of the samples were spiked with a surrogate compound
with a known concentration before preparation. The surrogate and MS/MSD data provides a measure of
the matrix effects as they may affect accuracy and precision of the analytical method. The LCS results
demonstrate accuracy of the method. Spike recoveries were within the method acceptance limits,
showing no evidence of matrix interferences that affect the usability of the data.
Representativeness criteria are a qualitative measure of the degree to which sample data accurately
and precisely represent a characteristic environmental condition. Representativeness is a subjective
parameter and is used to evaluate the efficacy of the sampling plan design. Representativeness was
demonstrated by providing full descriptions in the project scoping documents of the sampling techniques
and the rationale used for selecting sampling locations.
Completeness is defined as the percentage of measurements that are judged to be valid compared to
the total number of measurements made. There were no data rejected and or seen as not usable due to
quality control or sampling issues.
Comparability is another qualitative measure designed to express the confidence with which one data
set may be compared to another. Factors that affect comparability are sample collection and handling
techniques, sample matrix type, and analytical method. Comparability is limited by the other PARCC
parameters because data sets can be compared with confidence only when precision and accuracy are
known. Data from this investigation are comparable with other previous data collected at the site due to
the laboratories use of EPA or appropriate methods to analyze the samples and supported by the results
of the laboratory's analytical reports.
6. Conclusion
A review of the analytical data submitted regarding the investigation of PPL Poplar Tent Road soil vapor
sampling event in October 2018 by Jacobs has been completed. The validation demonstrated that the
analytical systems were in control and all data results can be used in the decision -making process.

RE: Poplar Tent Road Site / 699855CH.PT.EM
Dear Mike:
Enclosed are the results of the samples submitted to our laboratory on October 23, 2018. For
your reference, these analyses have been assigned our service request number PI 805716.
All analyses were performed according to our laboratory's NELAP and DoD-ELAP-approved quality
assurance program. The test results meet requirements of the current NELAP and DoD-ELAP
standards, where applicable, and except as noted in the laboratory case narrative provided. For a
specific list of NELAP and DoD-ELAP-accredited analytes, refer to the certifications section at
www.alsglobal.com. Results are intended to be considered in their entirety and apply only to the
samples analyzed and reported herein.
If you have any questions, please call me at [phone].
Respectfully submitted,

CASE NARRATIVE
The samples were received intact under chain of custody on October 23, 2018 and were stored in
accordance with the analytical method requirements. Please refer to the sample acceptance check
form for additional information. The results reported herein are applicable only to the condition of
the samples at the time of sample receipt.
Due to instrumentation issues the samples were analyzed by EPA TO-1 5 SIM but reported to the
low level scan reporting limits.
Volatile Organic Compound Analysis
The samples were analyzed in SIM mode for volatile organic compounds in accordance with EPA
Method TO-15 from the Compendium of Methods for the Determination of Toxic Organic
Compounds in Ambient Air, Second Edition (EPA/625/R-96/010b), January, 1999. This
procedure is described in laboratory SOP VOA-TO1 5. The analytical system was comprised of a
gas chromatograph / mass spectrometer (GC/MS) interfaced to a whole -air preconcentrator.
This method is included on the laboratory's NELAP and DoD-ELAP scope of accreditation. Any
analytes flagged with an X are not included on the NELAP or DoD-ELAP accreditation.
The containers were cleaned, prior to sampling, down to the method reporting limit (MRL)
reported for this project. For projects requiring DoD QSM 5.1 compliance canisters were
cleaned to <1 /2 the MRL. Please note, projects which require reporting below the MRL could
have results between the MRL and method detection limit (MDQ that are biased high.
The results of analyses are given in the attached laboratory report. All results are intended to be considered in their
entirety, and ALS Environmental (ALS) is not responsible for utilization of less than the complete report.
Use of ALS Environmental (ALS)'s Name. Client shall not use ALS's name or trademark in any marketing or reporting
materials, press releases or in any other manner ("Materials') whatsoever and shall not attribute to ALS any test result,
tolerance or specification derived from ALS's data ('Attribution') without ALS's prior written consent, which may be withheld
by ALS for any reason in its sole discretion. To request ALS's consent, Client shall provide copies of the proposed Materials
or Attribution and describe in writing Client's proposed use of such Materials or Attribution. If ALS has not provided written
approval of the Materials or Attribution within ten (10) days of receipt from Client, Client's request to use ALS's name or
trademark in any Materials or Attribution shall be deemed denied. ALS may, in its discretion, reasonably charge Client for
its time in reviewing Materials or Attribution requests. Client acknowledges and agrees that the unauthorized use of ALS's
name or trademark may cause ALS to incur irreparable harm for which the recovery of money damages will be inadequate.
Accordingly, Client acknowledges and agrees that a violation shall justify preliminary injunctive relief. For questions contact
the laboratory.

RE: Poplar Tent Road Site / 699855.CH.PT.EM
Dear Mike:
Enclosed are the results of the samples submitted to our laboratory on October 25, 2018. For
your reference, these analyses have been assigned our service request number PI 805822.
All analyses were performed according to our laboratory's NELAP and DoD-ELAP-approved quality
assurance program. The test results meet requirements of the current NELAP and DoD-ELAP
standards, where applicable, and except as noted in the laboratory case narrative provided. For a
specific list of NELAP and DoD-ELAP-accredited analytes, refer to the certifications section at
www.alsglobal.com. Results are intended to be considered in their entirety and apply only to the
samples analyzed and reported herein.
If you have any questions, please call me at [phone].
Respectfully submitted,
ALS I Environmental

CASE NARRATIVE
The samples were received intact under chain of custody on October 25, 2018 and were stored in
accordance with the analytical method requirements. Please refer to the sample acceptance check
form for additional information. The results reported herein are applicable only to the condition of
the samples at the time of sample receipt.
Volatile Organic Compound Analysis
The samples were analyzed for volatile organic compounds in accordance with EPA Method TO-
1 5 from the Compendium of Methods for the Determination of Toxic Organic Compounds in
Ambient Air, Second Edition (EPA/625/R-96/01 Ob), January, 1999. This procedure is described
in laboratory SOP VOA-TO1 5. The analytical system was comprised of a gas chromatograph /
mass spectrometer (GC/MS) interfaced to a whole -air preconcentrator. This method is included
on the laboratory's NELAP and DoD-ELAP scope of accreditation. Any analytes flagged with an X
are not included on the NELAP or DoD-ELAP accreditation.
The containers were cleaned, prior to sampling, down to the method reporting limit (MRL)
reported for this project. For projects requiring DoD QSM 5.1 compliance canisters were
cleaned to <1 /2 the MRL. Please note, projects which require reporting below the MRL could
have results between the MRL and method detection limit (MDQ that are biased high.
The results of analyses are given in the attached laboratory report. All results are intended to be considered in their
entirety, and ALS Environmental (ALS) is not responsible for utilization of less than the complete report.
Use of ALS Environmental (ALS)'s Name. Client shall not use ALS's name or trademark in any marketing or reporting
materials, press releases or in any other manner ("Materials') whatsoever and shall not attribute to ALS any test result,
tolerance or specification derived from ALS's data ('Attribution') without ALS's prior written consent, which may be withheld
by ALS for any reason in its sole discretion. To request ALS's consent, Client shall provide copies of the proposed Materials
or Attribution and describe in writing Client's proposed use of such Materials or Attribution. If ALS has not provided written
approval of the Materials or Attribution within ten (10) days of receipt from Client, Client's request to use ALS's name or
trademark in any Materials or Attribution shall be deemed denied. ALS may, in its discretion, reasonably charge Client for
its time in reviewing Materials or Attribution requests. Client acknowledges and agrees that the unauthorized use of ALS's
name or trademark may cause ALS to incur irreparable harm for which the recovery of money damages will be inadequate.
Accordingly, Client acknowledges and agrees that a violation shall justify preliminary injunctive relief. For questions contact
the laboratory.

Concord, North Carolina 28027
Subject: Results from Recent Soil Vapor Monitoring
Plantation Pipe Line Company
Poplar Tent Road Site
NCDEQ Groundwater Incident No. 88110
Dear Mr. and Mrs. Nestora,
14120 Ballantyne Corporate Place, Suite 200
Charlotte, North Carolina 28277
United States
T +1.704.544.4040
F +1.704.544.4041

Thank you for allowing Plantation Pipe Line Company's representatives (CH2M HILL, now part of
Jacobs Engineering Group Inc.) to conduct semiannual soil vapor monitoring activities on your property in
October 2018. The purpose of this letter is to provide a summary of the monitoring activities conducted on
your property, along with a summary of the analytical results.
October 2018 Monitoring Activities
On October 3, 2018, CH2M (now Jacobs) sent you an email requesting access to your property to collect
semiannual samples from soil vapor monitoring points SV-10R2, SV-12R, and SV-13R (see attached
figure). On October 17, 2018, leak checks were conducted on soil vapor monitoring points SV-10R2, SV-
12R, and SV-13R prior to collecting a vapor sample. These soil vapor monitoring points passed the leak
check and were purged with an electric sampling pump prior to sample collection. Soil vapor samples
were then collected using vacuum canisters and sampling syringes with charcoal tubes. The samples
were submitted to ALS Environmental (ALS) in Simi Valley, California for analysis of benzene, toluene,
ethylbenzene, xylenes (BTEX), naphthalene, and 2-methyl naphthalene.
Analytical Results
The analytical data from the October 17, 2018 monitoring event are attached to this letter and are
summarized in Table 1. When reviewing the laboratory analytical report, please note the sample
identifications for your soil vapor monitoring points are SV-10R2-101718, SV-12R-101718, and SV-13R-
101718. Data from historical monitoring events are shown in Table 2.
The analytical results show that the samples collected in October 2018 were significantly lower than North
Carolina Department of Environmental Quality (NCDEQ) and United States Environmental Protection
Agency (USEPA) regulatory screening criteria, as shown in Table 1. The purpose of these soil gas criteria
is for "screening" site data to help identify areas, contaminants, and conditions that may require further
evaluation or attention.

The results of the October 2018 monitoring event are generally consistent with the results of the previous
monitoring events. As shown in Table 2, some variability is apparent when comparing the data from the
historical monitoring events. In general, soil vapor monitoring results are expected to vary due to several
factors, including seasonal temperature changes, changes in barometric pressure, changes in water table
elevations, changes in subsurface conditions due to precipitation prior to a monitoring event, changes in
subsurface conditions due to operation of the remediation system, and variations in the contaminant
source concentrations. Also, because the soil vapor monitoring points have been replaced (SV-1 OR was
replaced by SV-10R2 in 2014 and SV-12 was replaced by SV-12R in 2012), they are currently installed in
slightly different locations compared to the original monitoring points.
Soil Vapor Monitoring Plan
The next semiannual monitoring event is planned for April 2019. Jacobs will contact you separately to
coordinate this monitoring event.
Thank you for your assistance and we apologize for any inconvenience this sampling program may
cause. Please feel free to contact me at 704.543.3285 or Jerry Aycock with Plantation at 770.751.4165 if
you have any questions about the monitoring results. The NCDEQ is an additional resource to discuss
aspects of the site and our monitoring activities. Ms. Trudy Beverly is the NCDEQ case manager and can
be contacted at 704.663.1699 concerning this site (NCDEQ Incident #88110).
Again, thank you for your cooperation
Sincerely,
Mike Skeean, P.E.

1. Introduction
The purpose of this memorandum is to present the results of the data validation process for the soil vapor
samples collected at the Plantation Pipe Line Company (PPL) Poplar Tent Road. The samples were
collected in October 2018.
Samples were submitted to ALS Global in Simi Valley, California for the following analyses:
• T015 SIM Volatiles
• T017 Volatiles
These data were validated for compliance with the analytical method requirements. This process included
a review of these data to assess the accuracy, precision, and completeness based upon procedures
described in guidance documents such as the Environmental Protection Agency (EPA) National
Functional Guidelines for Organic Data Review (EPA 2017). The Quality assurance/quality control
(QA/QC) summary forms and data reports were reviewed and the resulting findings are documented
within each subsection that follows.
During the data validation, if QA/QC parameters were not within the acceptance limits, associated sample
results were appended with a primary qualifying flag that indicated a possible anomaly with these data.
The qualifying flags originated during the data review and validation processes. This qualification also
included the use of secondary sub -qualifier flags. The secondary qualifiers provide the reasoning behind
the assignment of a qualifier to these data. The definitions of the primary qualifiers are presented below.
2. Validation Flag Definitions
The following primary qualifiers were used to qualify the data:
[_]: Detected. The analyte was analyzed for and detected at the concentration shown.
[J]: Estimated. The analyte was present but the reported value may not be accurate or precise.
[U]: Undetected. The analyte was analyzed for but not detected above the method detection limit.
[UJ]: Detection limit estimated. The analyte was analyzed for but qualified as not detected; the
detection limit is estimated.
[R]: Rejected. The data are not useable.
[X]: Excluded. Data were not used due to another value being more appropriate.

3. Organic Parameters
3.1 Quality Control Review
The following list represents the QA/QC measures that were reviewed during the data quality evaluation
procedure for organic data:
• Holding Times — The holding times are evaluated to verify that samples were extracted and
analyzed within holding times.
• Blank samples — Method blank samples were provided for this project. Blank samples enable the
reviewer to determine if an analyte may be attributed to sampling or laboratory procedures, rather
than environmental contamination from site activities.
• Surrogate Recoveries — Surrogate Compounds are added to each sample and the recoveries are
used to monitor lab performance and possible matrix interference.
• Lab Control Sample (LCS) — These samples are a "controlled matrix", laboratory reagent water, in
which target compounds have been added prior to extraction/analysis. The recoveries serve as a
monitor of the overall performance of each step during the analysis, including sample preparation.
• Matrix Spike/Matrix Spike Duplicate (MS/MSD) Samples — Spike recovery is used to evaluate
potential matrix interferences, as well as accuracy. Precision information is also determined by
calculating the reproducibility between the recoveries of each spiked parameter.
• Field Duplicate Samples — These samples are collected to determine precision between a native
and its duplicate. This information can only be determined when target compounds are detected.
4. Volatile Organic Compound Analyses
The QA/QC parameters for VOC analyses by SW-846 8260B for all samples were within acceptable
control limits with the exceptions listed below. A brief overview of the data evaluation follows:
4.1 Holding Time
All holding time requirements were met.
4.2 Field Duplicates
Duplicate field samples were collected and submitted to the laboratory for analysis. There are two
conditions under which the native and field duplicate are deemed outside acceptance criteria. For
condition one, if a result for the native and field duplicate are less than five times the reporting limit, the
two results must be within one times the reporting limit to meet acceptance criteria. In condition two, if the
result is greater than five times the reporting limit, the two results must agree to within 20 percent relative
percent difference to meet acceptance criteria. All acceptance criteria were met.
4.3 Recoveries — Surrogates, MS/MSD, LCS/LCSD
Surrogates and LCS/LCSD recoveries all met acceptance criteria. A MS/MSD set was not collected for
this event.
4.4 Analytical Blanks
No target analytes were detected in the blanks.

Data Validation Summary - Plantation Pipe Line Poplar Tent Road Site JACOBSW
5. PARCC
Precision is defined as the agreement between duplicate results, and was estimated by comparing
duplicate MS recoveries, and field duplicate sample results. The precision between the native and field
duplicate sample results for all analyses were within acceptable criteria indicating that the sample matrix
did not interfere with the overall analytical process.
Accuracy is a measure of the agreement between an experimental determination and the true value of
the parameter. In the case of VOC analysis, each of the samples were spiked with a surrogate compound
with a known concentration before preparation. The surrogate and MS/MSD data provides a measure of
the matrix effects as they may affect accuracy and precision of the analytical method. The LCS results
demonstrate accuracy of the method. Spike recoveries were within the method acceptance limits,
showing no evidence of matrix interferences that affect the usability of the data.
Representativeness criteria are a qualitative measure of the degree to which sample data accurately
and precisely represent a characteristic environmental condition. Representativeness is a subjective
parameter and is used to evaluate the efficacy of the sampling plan design. Representativeness was
demonstrated by providing full descriptions in the project scoping documents of the sampling techniques
and the rationale used for selecting sampling locations.
Completeness is defined as the percentage of measurements that are judged to be valid compared to
the total number of measurements made. There were no data rejected and or seen as not usable due to
quality control or sampling issues.
Comparability is another qualitative measure designed to express the confidence with which one data
set may be compared to another. Factors that affect comparability are sample collection and handling
techniques, sample matrix type, and analytical method. Comparability is limited by the other PARCC
parameters because data sets can be compared with confidence only when precision and accuracy are
known. Data from this investigation are comparable with other previous data collected at the site due to
the laboratories use of EPA or appropriate methods to analyze the samples and supported by the results
of the laboratory's analytical reports.
6. Conclusion
A review of the analytical data submitted regarding the investigation of PPL Poplar Tent Road soil vapor
sampling event in October 2018 by Jacobs has been completed. The validation demonstrated that the
analytical systems were in control and all data results can be used in the decision -making process.

RE: Poplar Tent Road Site / 699855CH.PT.EM
Dear Mike:
Enclosed are the results of the samples submitted to our laboratory on October 23, 2018. For
your reference, these analyses have been assigned our service request number PI 805716.
All analyses were performed according to our laboratory's NELAP and DoD-ELAP-approved quality
assurance program. The test results meet requirements of the current NELAP and DoD-ELAP
standards, where applicable, and except as noted in the laboratory case narrative provided. For a
specific list of NELAP and DoD-ELAP-accredited analytes, refer to the certifications section at
www.alsglobal.com. Results are intended to be considered in their entirety and apply only to the
samples analyzed and reported herein.
If you have any questions, please call me at [phone].
Respectfully submitted,
ALS I Environmental

Client: Jacobs Service Request No: PI 805716
Project: Poplar Tent Road Site / 699855CH.PT.EM
CASE NARRATIVE
The samples were received intact under chain of custody on October 23, 2018 and were stored in
accordance with the analytical method requirements. Please refer to the sample acceptance check
form for additional information. The results reported herein are applicable only to the condition of
the samples at the time of sample receipt.
Due to instrumentation issues the samples were analyzed by EPA TO-1 5 SIM but reported to the
low level scan reporting limits.
Volatile Organic Compound Analysis
The samples were analyzed in SIM mode for volatile organic compounds in accordance with EPA
Method TO-15 from the Compendium of Methods for the Determination of Toxic Organic
Compounds in Ambient Air, Second Edition (EPA/625/R-96/010b), January, 1999. This
procedure is described in laboratory SOP VOA-TO1 5. The analytical system was comprised of a
gas chromatograph / mass spectrometer (GC/MS) interfaced to a whole -air preconcentrator.
This method is included on the laboratory's NELAP and DoD-ELAP scope of accreditation. Any
analytes flagged with an X are not included on the NELAP or DoD-ELAP accreditation.
The containers were cleaned, prior to sampling, down to the method reporting limit (MRL)
reported for this project. For projects requiring DoD QSM 5.1 compliance canisters were
cleaned to <1 /2 the MRL. Please note, projects which require reporting below the MRL could
have results between the MRL and method detection limit (MDQ that are biased high.
The results of analyses are given in the attached laboratory report. All results are intended to be considered in their
entirety, and ALS Environmental (ALS) is not responsible for utilization of less than the complete report.
Use of ALS Environmental (ALS)'s Name. Client shall not use ALS's name or trademark in any marketing or reporting
materials, press releases or in any other manner ("Materials') whatsoever and shall not attribute to ALS any test result,
tolerance or specification derived from ALS's data ('Attribution') without ALS's prior written consent, which may be withheld
by ALS for any reason in its sole discretion. To request ALS's consent, Client shall provide copies of the proposed Materials
or Attribution and describe in writing Client's proposed use of such Materials or Attribution. If ALS has not provided written
approval of the Materials or Attribution within ten (10) days of receipt from Client, Client's request to use ALS's name or
trademark in any Materials or Attribution shall be deemed denied. ALS may, in its discretion, reasonably charge Client for
its time in reviewing Materials or Attribution requests. Client acknowledges and agrees that the unauthorized use of ALS's
name or trademark may cause ALS to incur irreparable harm for which the recovery of money damages will be inadequate.
Accordingly, Client acknowledges and agrees that a violation shall justify preliminary injunctive relief. For questions contact
the laboratory.

RE: Poplar Tent Road Site / 699855.CH.PT.EM
Dear Mike:
Enclosed are the results of the samples submitted to our laboratory on October 25, 2018. For
your reference, these analyses have been assigned our service request number PI 805822.
All analyses were performed according to our laboratory's NELAP and DoD-ELAP-approved quality
assurance program. The test results meet requirements of the current NELAP and DoD-ELAP
standards, where applicable, and except as noted in the laboratory case narrative provided. For a
specific list of NELAP and DoD-ELAP-accredited analytes, refer to the certifications section at
www.alsglobal.com. Results are intended to be considered in their entirety and apply only to the
samples analyzed and reported herein.
If you have any questions, please call me at [phone].
Respectfully submitted,
ALS I Environmental

CASE NARRATIVE
The samples were received intact under chain of custody on October 25, 2018 and were stored in
accordance with the analytical method requirements. Please refer to the sample acceptance check
form for additional information. The results reported herein are applicable only to the condition of
the samples at the time of sample receipt.
Volatile Organic Compound Analysis
The samples were analyzed for volatile organic compounds in accordance with EPA Method TO-
1 5 from the Compendium of Methods for the Determination of Toxic Organic Compounds in
Ambient Air, Second Edition (EPA/625/R-96/01 Ob), January, 1999. This procedure is described
in laboratory SOP VOA-TO1 5. The analytical system was comprised of a gas chromatograph /
mass spectrometer (GC/MS) interfaced to a whole -air preconcentrator. This method is included
on the laboratory's NELAP and DoD-ELAP scope of accreditation. Any analytes flagged with an X
are not included on the NELAP or DoD-ELAP accreditation.
The containers were cleaned, prior to sampling, down to the method reporting limit (MRL)
reported for this project. For projects requiring DoD QSM 5.1 compliance canisters were
cleaned to <1 /2 the MRL. Please note, projects which require reporting below the MRL could
have results between the MRL and method detection limit (MDQ that are biased high.
The results of analyses are given in the attached laboratory report. All results are intended to be considered in their
entirety, and ALS Environmental (ALS) is not responsible for utilization of less than the complete report.
Use of ALS Environmental (ALS)'s Name. Client shall not use ALS's name or trademark in any marketing or reporting
materials, press releases or in any other manner ("Materials') whatsoever and shall not attribute to ALS any test result,
tolerance or specification derived from ALS's data ('Attribution') without ALS's prior written consent, which may be withheld
by ALS for any reason in its sole discretion. To request ALS's consent, Client shall provide copies of the proposed Materials
or Attribution and describe in writing Client's proposed use of such Materials or Attribution. If ALS has not provided written
approval of the Materials or Attribution within ten (10) days of receipt from Client, Client's request to use ALS's name or
trademark in any Materials or Attribution shall be deemed denied. ALS may, in its discretion, reasonably charge Client for
its time in reviewing Materials or Attribution requests. Client acknowledges and agrees that the unauthorized use of ALS's
name or trademark may cause ALS to incur irreparable harm for which the recovery of money damages will be inadequate.
Accordingly, Client acknowledges and agrees that a violation shall justify preliminary injunctive relief. For questions contact
the laboratory.
