Hello,
Attached please find the sample confirmation files for job 570-87328-1; Rohr Chula Vista-Parcel A/0127827-043

1. The container labels for the following sample did not match the information listed on the Chain-of-Custody (COC): NCB-021-B-050 (570-87328-19). The container labels list NCW-021- B-050, while the COC lists NCB-021-B-050 (collection date matches).

ACTION: Please provide clarification on the above sample ID.

Please feel free to contact me if you have any questions.

Thank you.

Receipt
The samples were received on 3/9/2022 6:30 PM. 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.

Receipt Exception
A trip blank was submitted for analysis with these samples; however, it was not listed on the Chain of Custody (COC).

The client was contacted with the above sample receipt anomaly. The laboratory was provided written direction on how to proceed; please refer to the COC section of the report for further details.

GC/MS VOA
Method 8260B: The matrix spike / matrix spike duplicate (MS/MSD) recoveries for the following sample associated with preparation batch 570-219962 and analytical batch 570-219837 were outside control limits: (570-87413-A-15-C MSD). The associated laboratory control sample (LCS) recovery met acceptance criteria.

Method 8260B: Internal standard (ISTD) response for TBA-d9 for the following sample in analytical batch 570-219837 was outside acceptance criteria: DGA-013-10 (570-87413-3). This ISTD does not correspond to any of the requested target compounds reported from this analytical batch; therefore, the data have been reported.

Method 8260B: The matrix spike / matrix spike duplicate (MS/MSD) recoveries and precision for preparation batch 570-219929 and analytical batch 570-219835 were outside control limits. Sample matrix interference and/or non-homogeneity are suspected because the associated laboratory control sample / laboratory sample control duplicate (LCS/LCSD) recoveries and precision were within acceptance limits.

Method 8260B: The laboratory control sample (LCS) and / or laboratory control sample duplicate (LCSD) for preparation batch 570-219929 and analytical batch 570-219835 recovered outside control limits for Acetone. This analyte was biased high in the LCS and was not detected in the associated samples; therefore, the data have been reported.

Method 8260B: The matrix spike / matrix spike duplicate (MS/MSD) precision for preparation batch 570-220192 and analytical batch 570-220282 was outside control limits. Sample matrix interference is suspected.

Method 8260B: Sample dilution was required prior to analysis due to matrix interferences from sediment that precludes analysis by purge and trap for samples DGA-012-20-GW (570-87413-10) and DGA-020-20-GW (570-87413-24). The reporting limits (RLs) have been adjusted proportionately.

Method 8260B: The continuing calibration verification (CCV) associated with batch 570-221166 recovered above the upper control limit for Dichlorodifluoromethane. The samples associated with this CCV were non-detects for the affected analyte; therefore, the data have been reported.

Method 8260B: The laboratory control sample (LCS) and / or laboratory control sample duplicate (LCSD) for analytical batch 570-221166 recovered outside control limits for Dichlorodifluoromethane. This analyte was biased high in the LCS and was not detected in the associated samples; therefore, the data have been reported.

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