Data Flags & Calculations:
Analytical Lab
Page 1 of 39
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.

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.
