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.

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.

Sample was re-extracted due to PFHxA contamination in the MB. 646119005 (W110723-RK).

Miscellaneous Information

Additional Comments

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 1205584270 (MB),
1205584271 (LCS), 1205584272 (Non SDG 646466002MS), 1205584273 (Non SDG 646466002MSD) and
646119005 (W110723-RK) 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

Matrix Spike (MS) Recovery Statement
The MS or MSD (See Below) recovered spiked analytes outside of the established acceptance limits. As similar
recoveries were displayed in the MS and MSD, the failures were attributed to sample matrix interference and the
data were reported.

MS/MSD Relative Percent Difference (RPD) Statement
The RPD values between the MS and MSD (See Below) were not within the acceptance limits. Since all other
RPD values met acceptance criteria, the noted exceptions are attributed to vagaries in the extraction process. The
