Receipt
The samples were received on 3/20/2023 10:04 AM. Unless otherwise noted below, the samples arrived in good condition, and where required, properly preserved and on ice. The temperature of the cooler at receipt was 3.2º C.

GC/MS VOA
Method 8260B: Insufficient sample volume was available to perform a matrix spike/matrix spike duplicate (MS/MSD) associated with analytical batch 570-313157. The laboratory control sample (LCS) was performed in duplicate (LCSD) to provide precision data for this batch.

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

GC/MS Semi VOA
Method 8270C SIM: Samples are Dark/Black. SB10-2 (570-131785-10) and SB11-2 (570-131785-11) No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

Metals
Method 6010B: The matrix spike / matrix spike duplicate (MS/MSD) recoveries for preparation batch 570-313229 and analytical batch 570-313660 were outside control limits for one or more analytes, see QC Sample Results for detail. Sample matrix interference and/or non-homogeneity are suspected because the associated laboratory control sample (LCS) recovery is within acceptance limits.

Method 6010B: The serial dilution performed for the following sample associated with batch 570-315464 was outside control limits for Zinc: (570-131803-A-2-F SD ^25)
Method 6010B: The matrix spike / matrix spike duplicate (MS/MSD) recoveries of Barium, Lead and Antimony for preparation batch 570-314037 and analytical batch 570-315464 were outside control limits. Sample matrix interference and/or non-homogeneity are 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.

Organic Prep
Method 3546: Due to the matrix, the following sample could not be concentrated to the final method required volume: SB10-2 (570-131785-10). The reporting limits (RLs) are elevated proportionately.The final volume was changed from 2mL to 4mL. 8270S I M P A H
No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

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