Program Comments:
As per Pace analytical, Methane holding times were exceeded for work order J16050381: samples AS-09 (2016013674) and
SW-104 (2016013675). Client has been notified.
Data Flags & Calculations:
Any analytical tests or individual analytes within a test flagged with a Qualifier indicate a deviation from the method quality
system or quality control requirement. The qualifier description is found at the end of the Certificate of Analysis (sample results)
under the qualifiers heading. All results are reported on a dry weight basis unless otherwise noted. Subcontracted data
included on the Duke Certificate of Analysis is to be used as information only. Certified vendor results can be found in the
subcontracted lab final report. Duke Energy Analytical Laboratory subcontracts analyses to other vendor laboratories that have
been qualified by Duke Energy to perform these analyses except where noted.
Data Package:
This data package includes analytical results that are applicable only to the samples described in this narrative. An estimation of
the uncertainty of measurement for the results in the report is available upon request. This report shall not be reproduced, except
in full, without the written consent of the Analytical Laboratory. Please contact the Analytical laboratory with any questions. The
order of individual sections within this report is as follows:
Job Summary Report, Sample Identification, Technical Validation of Data Package, Analytical Laboratory Certificate of Analysis,
Analytical Laboratory QC Reports, Sub -contracted Laboratory Results, Customer Specific Data Sheets, Reports &
Documentation, Customer Database Entries, Test Case Narratives, Chain of Custody (COC)
Certification:
The Analytical Laboratory holds the following State Certifications : North Carolina (DENR) Certificate #248, South Carolina
(DHEC) Laboratory ID # 99005. Contact the Analytical Laboratory for definitive information about the certification status of
specific methods.

DEFINITIONS
DF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot.
ND - Not Detected at or above adjusted reporting limit.
J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
MDL -Adjusted Method Detection Limit.
PQL - Practical Quantitation Limit.
RL - Reporting Limit.
S - Surrogate
1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is
a combined concentration.
Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values.
LCS(D) - Laboratory Control Sample (Duplicate)
MS(D) - Matrix Spike (Duplicate)
DUP - Sample Duplicate
RPD - Relative Percent Difference
NC - Not Calculable.
SG - Silica Gel - Clean -Up
U - Indicates the compound was analyzed for, but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether, Styrene, and Vinyl chloride.
A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA
Method 8260.
N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for
each analyte is a combined concentration.
Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes.

The Qualifiers in this report are defined as follows:
* A quality control analyte recovery is outside of specified acceptance criteria
** Analyte is a Tracer compound
** Analyte is a surrogate compound
J Value is estimated
U Analyte was analyzed for, but not detected above the MDL, MDA, MDC or LOD.
Where the analytical method has been performed under NELAP certification, the analysis has met all of the
requirements of the NELAC standard unless qualified on the Certificate of Analysis.
The designation ND, if present, appears in the result column when the analyte concentration is not detected above
the limit as defined in the 'U' qualifier above.
This data report has been prepared and reviewed in accordance with GEL Laboratories LLC
standard operating procedures. Please direct any questions to your Project Manager, Lindsay Fabra.

N/A indicates that spike recovery limits do not apply when sample concentration exceeds spike cone. by a factor of 4 or more or %RPD not applicable.
^ The Relative Percent Difference (RPD) obtained from the sample duplicate (DUP) is evaluated against the acceptance criteria when the sample is greater than
five times (5X) the contract required detection limit (RL). In cases where either the sample or duplicate value is less than 5X the RL, a control limit of +/- the

For PS, PSD, and SDILT results, the values listed are the measured amounts, not final concentrations.
