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, Delaney Stone.
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
B The target analyte was detected in the associated blank.
J See case narrative for an explanation
J Value is estimated
U Analyte was analyzed for, but not detected above the MDL, MDA, MDC or LOD.
X Consult Case Narrative, Data Summary package, or Project Manager concerning this qualifier
h Preparation or preservation holding time was exceeded

Analyte concentration is not detected above the detection limit
Consult Case Narrative, Data Summary package, or Project Manager concerning this qualifier
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.

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.

Internal Standard (ISTD) Acceptance
Industrial samples 597952003 (FT090722-21) and 597952004 (FTB090722-21) did not meet acceptance criteria
for one or more internal standards with a positive bias. The samples were diluted in order to bring internal
standards within acceptance criteria. The results for these samples were reported from the undiluted and diluted
analyses. Industrial samples 597952003 (FT090722-21) and 597952004 (FTB090722-21) did not meet
acceptance criteria for one or more internal standards with a negative bias. The sample was diluted in order to
bring internal standards within acceptance criteria. There was in sufficient sample remaining to allow for
re-extractions to determine if the failures were due to matrix interference or laboratory error. The results for
these samples were therefore reported as is from the undiluted and diluted analyses.

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 standards (ICV or CCV) requirements have not been met for samples 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
Industrial samples 597952014 (W090722-33) and 597952017 (D090722-21WD) did not meet acceptance criteria
for one or more internal standards with a positive bias. The samples were diluted in order to bring internal
