Receipt 

The samples were received on 7/7/2015 9:45 AM; the samples arrived in good condition, properly preserved and, where required, on ice. 

The temperature of the cooler at receipt was 5.3o C.

GC/MS VOA 

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

Metals 

Method(s) 6010B: The following samples was diluted due to the abundance of target and non-target analytes: VS Event 5 Composite 1 

(500-98230-2), (500-98230-B-2-B DU ^), (500-98230-B-2-C MS ^), (500-98230-B-2-D MSD) and (500-98230-B-2-A SD ^). Elevated 

reporting limits (RLs) are provided.

Method(s) 6010B: The following samples was diluted to bring the concentration of target analytes within the calibration range (too 

negative): VS Event 5 Composite 1 (500-98230-2), (500-98230-B-2-B DU ^), (500-98230-B-2-C MS ^), (500-98230-B-2-D MSD) and 

(500-98230-B-2-A SD ^). 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.

General Chemistry 

Method(s) 9034: The Reactive Sulfide matrix spike / matrix spike duplicate (MS/MSD) recoveries for 500-295526 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

GC/MS VOA

Qualifier Description

F2 MS/MSD RPD exceeds control limits

Qualifier

F1 MS and/or MSD Recovery is outside acceptance limits.

Metals

Qualifier Description

B Compound was found in the blank and sample.

Qualifier

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

F2 MS/MSD RPD exceeds control limits

F1 MS and/or MSD Recovery is outside acceptance limits.

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.

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.

General Chemistry

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

F1 MS and/or MSD Recovery is outside acceptance limits.

F2 MS/MSD RPD exceeds control limits

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.
