N/A
Analyte was analyzed for, but not detected above the MDL, MDA, MDC or LOD.
Value is estimated
Organics--The concentrations between the primary and confirmation columns/detectors is >40% different. For HPLC, the difference is >70%.
Analyte has been confirmed by GC/MS analysis
The target analyte was detected in the associated blank.
Concentration of the target analyte exceeds the instrument calibration range
The TIC is a suspected aldol-condensation product
Consult Case Narrative, Data Summary package, or Project Manager concerning this qualifier
Organics--Presumptive evidence based on mass spectral library search to make a tentative identification of the analyte (TIC). Quantitation is based
on nearest internal standard response factor
Analytical holding time was exceeded
Analyte is a surrogate compound
Result is less than value reported
Result is greater than value reported
Preparation or preservation holding time was exceeded
Sample results are rejected
RPD of sample and duplicate evaluated using +/-RL. Concentrations are <5X the RL. Qualifier Not Applicable for Radiochemistry.
Results are reported from a diluted aliquot of the sample
RPD or %Recovery limits do not apply.

Analyte concentration is not detected above the detection limit
Consult Case Narrative, Data Summary package, or Project Manager concerning this qualifier
Non Calibrated Compound
Compound cannot be extracted
One or more quality control criteria have not been met. Refer to the applicable narrative or DER.
See case narrative
QC Samples were not spiked with this compound
Presumptive evidence based on mass spectral library search to make a tentative identification of the analyte (TIC). Quantitation is based on nearest
internal standard response factor
See case narrative for an explanation
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 either the sample or 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
The internal standard response (13C3_PFPrOPra) was outside of the acceptance criteria for sample 611332002.
The sample was re-extracted and the result was not confirmed. Therefore, data was reported from the original
and re-extracted analyses. 611332002 (D012423-02).

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.

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.
