No additional comments. 

Receipt 

The samples were received on 5/12/2015 10:05 AM; the samples arrived in good condition, properly preserved and, where required, on 

ice.

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 batch 287972 had results for As above the reporting 

limit (RL). The method blank (MB), laboratory control sample (LCS), and all other associated QC were within limits. Sample 500-95814-3 

was a non-detect (ND) for As, therefore the data have been reported. 

Method(s) 6010B: The interference check standard solution (ICSAB) associated with batch 287972 had results for Se below the reporting 

limit (RL). The ICSA, method blank (MB), laboratory control sample (LCS), and all other associated QC were within limits. Sample 

interference is not suspected for Se, therefore the data have been reported. 

Method(s) 6010B: The continuing calibration verification (CCV) at line 60 in AD batch 287972 recovered above the upper control limit for Zn. 

The sample associated with this CCV was a non-detect for the affected analyte; therefore, the data have been reported. The following 

sample is impacted: 500-95814-3. 

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

Receipt 

The samples were received on 5/12/2015 10:05 AM; the samples arrived in good condition, properly preserved and, where required, on 

ice.

General Chemistry 

Method(s) 7196A: The method blank for Leach Batch 143090 contained Cr (VI) above the reporting limit (RL). Associated sample(s) were 

re-leached . In both leachate batches, the leachate blank contained Hexachrome above the reporting limit. The Hexachrome result in the 

sample was greater than 10 times the sample, therefore the results were reported. Only the second set of data has been reported.

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

Geotechnical 

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