Organics--The concentrations between the primary and confirmation columns/detectors is >40% different. For HPLC, the difference is >70%.
One or more quality control criteria have not been met. Refer to the applicable narrative or DER.
Sample results are rejected
Analyte was analyzed for, but not detected above the MDL, MDA, MDC or LOD.
Compound cannot be extracted
Consult Case Narrative, Data Summary package, or Project Manager concerning this qualifier
QC Samples were not spiked with this compound
RPD of sample and duplicate evaluated using +/-RL. Concentrations are <5X the RL. Qualifier Not Applicable for Radiochemistry.
Preparation or preservation holding time was exceeded
N/A indicates that spike recovery limits do not apply when sample concentration exceeds spike conc. 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 the duplicate value is less than 5X the RL, a control limit of +/- the RL is used to
evaluate the DUP result.
* Indicates that a Quality Control parameter was not within specifications.
For PS, PSD, and SDILT results, the values listed are the measured amounts, not final concentrations.
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 QC Summary.

SDG #: 599737

Product: The Extraction and Analysis of Per- and Polyfluoroalkyl Substances Using LCMSMS
Analytical Method: EPA 537.1 Modified
Analytical Procedure: GL-OA-E-076 REV# 12
Analytical Batches: 2343845 and 2343831
The following samples were analyzed using the above methods and analytical procedure(s).

The samples in this SDG were analyzed on an "as received" basis.
Data Summary:

All sample data provided in this report met the acceptance criteria specified in the analytical methods and
procedures for initial calibration, continuing calibration, instrument controls and process controls where
applicable, with the following exceptions.

Calibration Information

CCV Requirements
Calibration verification standard (ICV or CCV) requirements have not been met for sample 599737001
(TB110322-00) in this batch in this SDG. One or more target analytes failed acceptance criteria with a positive
bias in the standards bracketing the samples in this SDG. These target analytes were not detected in the
associated environmental samples; therefore, the non-compliance had no adverse effect on the data.

Quality Control (QC) Information

Internal Standard (ISTD) Acceptance
Samples (See Below) exceeded internal standard acceptance criteria for 1,2-13C2 Fluorotelomer sulfonate 6:2
with a positive bias. There were no detections of the associated native target analyte Fluorotelomer sulfonate 6:2
(6:2 FTS) in the samples. These were Field Blank and/or Trip Blank samples therefore the samples were not
diluted in order to bring the internal standard within acceptance criteria. Data were reported as is.
Sample Analyte Value
599737001 (TB110322-00)1, 2-13C2 Fluorotelomer sulfonate 6:2 188* (40%-160%)

The samples in this SDG were analyzed on an "as received" basis.
Data Summary:

All sample data provided in this report met the acceptance criteria specified in the analytical methods and
procedures for initial calibration, continuing calibration, instrument controls and process controls where
applicable, with the following exceptions.

Quality Control (QC) Information

Internal Standard (ISTD) Acceptance
QC and client samples (See Below) exceeded internal standard acceptance criteria for 1,2-13C2 Fluorotelomer
sulfonate 6:2 and/or 1,2-13C2 Fluorotelomer sulfonate 4:2 with a positive bias. There were no detections of the
associated native target analytes Fluorotelomer sulfonate 6:2 (6:2 FTS) or Fluorotelomer sulfonate 4:2 (4:2 FTS)
in the client samples. Data for these samples were therefore reported as is.

Miscellaneous Information

Additional Comments
Some analytes are X qualified because the standards used to make the initial calibration curve did not meet the
ISO 17025 criterion. These are the only standard available for these analytes. A LCS/LCSD pair was extracted
and analyzed in place of sample matrix QC.

Certification Statement

Where the analytical method has been performed under NELAP certification, the analysis has met all of the
requirements of the NELAC standard unless otherwise noted in the analytical case narrative.
