QC REFERENCE
QC Report Types
(1) Calibration Verification-Blanks Verifies that there is no or minimal contamination in the instrument calibration.
(2) Calibration Verification-Control Samples Verifies the accuracy of the instrument calibration.
(3) Method Verification-Blanks Verifies that there is no or minimal contamination in the prep method procedure.
(4) Method Verification-Control Samples Verifies the accuracy of the method,including the prep procedure.
(5) Spike Verification Determines sample matrix interferences,if any.
(6) Duplicate Verification Verifies the precision of the instrument and/or method.
QC Sample Types
ICV Initial Calibration Verification AS Analytical(Post Digestion)Spike
CCV Continuing Calibration Verification MS Matrix Spike
LCSW Laboratory Control Sample-Water ASD Analytical Spike(Post Digestion)Duplicate
LCSS Laboratory Control Sample-Soil MSD Matrix Spike Duplicate
ICB Initial Calibration Blank DUP Sample Duplicate
CCB Continuing Calibration Blank
PBW Prep Blank-Water
PBS Prep Blank-Soil
Onique ACZ QC Summary Qualifiers(Q)
Z Poor spike recovery is accepted because sample concentration is four times greater than spike concentration.
Y This sample, instead of one of yours,was used as the quality control sample for the workgroup batch.
X QC is out of control. See Case Narrative.
W Poor recovery for Silver quality control is accepted because Silver often precipitates with Chloride.
V High blank data accepted because sample concentration is 10 times higher than blank concentration
T High Relative Percent Difference(RPD)accepted because sample concentrations are less than lOx the MDL.

Comments
(1) QC results calculated from raw data. Results may be vary slightly if the reported(rounded)values are used in the calculations.
(2) Soil.Sludge,and Plant matrices for Inorganic analyses are reported on a dry weight basis.
(3) Animal matrices for Inorganic analyses are reported on an"as received"basis.
(4) All matrices for Organic analyses are reported on an"as received"basis,except for TPH-IR analyses on soils
which are reported on a dry weight basis.
• (5) The PCN/SCN header on the QC reports stands for Primary Control Number/Secondary Control Number.
All stock chemicals are given a PCN and any reagent made at the bench level is assigned a SCN. These numbers track
our standards and chemicals so that any reagent is traceable to a certificate of analysis.
