Receipt 

The samples were received on 12/18/2014 9:45 AM; the samples arrived in good condition, properly preserved and, where required, on 

ice. The temperature of the cooler at receipt was 2.7o 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 interference check standard solution (ICSA) associated with AD batch 269795 had results for Cd above the 

reporting limit (RL). Associated samples 500-89685-3 and 4 were non-detects for Cd, therefore the data has been reported.

Method(s) 6010B: The laboratory blank (LB) for preparation batch 269604 contained Pb above the reporting limit (RL). The sample 

500-89685-3 associated with this LB did not contain the target compound; therefore, re-extraction and/or re-analysis of samples were not 

performed.

Method(s) 6010B: The continuing calibration verification (CCV) at lines 50, 74,and 80 in AD batch 270254 recovered above the upper 

control limit for Zn. The sample associated with these CCV was a non-detecs for the affected analyte; therefore, the data have been 

reported. The following sample is impacted: 500-89685-5.

Method(s) 6010B: The following samples were diluted due to initial results that were more than twice as negative as the reporting limit 

(RL): 500-89685 3 & 4. Elevated reporting limits are provided.

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

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

Qualifiers

Metals

Qualifier Description

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

Qualifier

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.

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.

General Chemistry

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.

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