Comments

No additional comments. 

Receipt 

The samples were received on 2/3/2015 1:00 PM; the samples arrived in good condition, properly preserved and, where required, on ice. 

The temperature of the cooler at receipt was 1.6o C.

GC/MS VOA 

Method(s) 8260B: The following sample was diluted to bring the concentration of target analytes within the calibration range: VS Event 2 

Discrete 1 (500-91647-1). Elevated reporting limits (RLs) are provided.

No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

Metals 

Method(s) 6010B: The continuing calibration verification (CCV) at line 86 in AD batch 274901 recovered above the upper control limit for Zn. 

The associated sample, 500-91647-3 was a non-detect for the affected analyte; therefore, the data has been reported.

Method(s) 6010B: Due to sample matrix effect on the internal standard (ISTD), a dilution was required for the following sample 

500-91647-2.

No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

General Chemistry 

Method(s) 7196A: The hexavalent chromium soluble matrix spike (MS) and the soluble/insoluble matrix spike duplicate (MSD) recoveries 

for batch 276426 were outside control limits. Sample matrix interference is suspected because the associated laboratory control sample 

(LCS) recovery was within acceptance limits.

No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

Qualifiers

Metals

Qualifier Description

J Result is less than the RL but greater than or equal to the MDL and the concentration is an approximate value.

Qualifier

B Compound was found in the blank and sample.

F5 Duplicate RPD exceeds limit, and one or both sample results are less than 5 times RL. The data are considered valid because the 

absolute difference is less than the RL.

F3 Duplicate RPD exceeds the control limit

4 MS, MSD: The analyte present in the original sample is greater than 4 times the matrix spike concentration; therefore, control limits are not 

applicable.

F1 MS and/or MSD Recovery exceeds the control limits

^ ICV,CCV,ICB,CCB, ISA, ISB, CRI, CRA, DLCK or MRL standard: Instrument related QC exceeds the control limits.

General Chemistry

Qualifier Description

F1 MS and/or MSD Recovery exceeds the control limits

Qualifier

HF Field parameter with a holding time of 15 minutes. Test performed by laboratory at client's request.

B Compound was found in the blank and sample.

J Result is less than the RL but greater than or equal to the MDL and the concentration is an approximate value.
