Job Narrative 380-141535-1

Analytical test results meet all requirements of the associated regulatory program listed on the Accreditation/Certification Summary Page unless otherwise noted under the individual analysis. Data qualifiers and/or narrative comments are included to explain any exceptions, if applicable.

· Matrix QC may not be reported if insufficient sample is provided or site-specific QC samples were not submitted. In these situations, to demonstrate precision and accuracy at a batch level, a LCS/LCSD may be performed, unless otherwise specified in the method.

· Surrogate and/or isotope dilution analyte recoveries (if applicable) which are outside of the QC window are confirmed unless attributed to a dilution or otherwise noted in the narrative.

Regulated compliance samples (e.g. SDWA, NPDES) must comply with the associated agency requirements/permits.

Receipt The sample was received on 3/20/2025 10:10 AM. Unless otherwise noted below, the sample arrived in good condition, and, where required, properly preserved and on ice. The temperature of the cooler at receipt time was 5.9°C.

GC/MS VOA

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: Surrogate recovery for the following sample was outside control limits: (570-223084-A-1-F MSD). Evidence of matrix interference is present; therefore, re-extraction and/or re-analysis was not performed.

Method 8270C: The continuing calibration verification (CCV) associated with batch 570-549108 recovered above the upper control limit for 4-Chloro-3-methylphenol. The samples associated with this CCV were non-detects for the affected analytes; therefore, the data have been reported. The associated samples are impacted: SFOI-SludgeProfile (380-141535-1) and (CCVIS 570-549108/2).

Method 8270C: The following sample was diluted due to the nature of the sample matrix: SFOI-SludgeProfile (380-141535-1).

Elevated reporting limits (RLs) are provided.

Method 8270C: The matrix spike / matrix spike duplicate (MS/MSD) recoveries for the following sample associated with preparation batch 570-547957 and analytical batch 570-548522 were outside control limits: (570-223084-A-1-E MS) and (570-223084-A-1-F MSD). The associated laboratory control sample (LCS) recovery met acceptance criteria.

Method 8270C: The following samples were diluted due to the nature of the sample matrix: (570-223084-A-1-G), (570-223084-A-1- E MS) and (570-223084-A-1-F MSD). 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.

Gasoline Range Organics Method 8015B_GRO: Surrogate recovery for the following sample was outside control limits: SFOI-SludgeProfile (380-141535-1).

Evidence of matrix interference is present; therefore, re-extraction and/or re-analysis was not performed.

Method 8015B_GRO: The matrix spike (MS) recoveries for preparation batch 570-551593 and analytical batch 570-551511 were outside control limits. Non-homogeneity 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.

Diesel Range Organics Method 8015B_DRO - Silica Gel Cleanup: Surrogate recovery for the following sample was outside control limits: SFOI- SludgeProfile (380-141535-1). Evidence of matrix interference is present; therefore, re-extraction and/or re-analysis was not performed.

Method 8015B_DRO - Silica Gel Cleanup: Due to the high concentration of C23-C44 and C13-C44, the matrix spike / matrix spike duplicate (MS/MSD) for preparation batch 570-549698 and 570-551160 and analytical batch 570-552861 could not be evaluated for accuracy and precision. The associated laboratory control sample (LCS) met acceptance criteria.

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

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

PCBs Method 8082: The following sample required a mercury clean-up, via EPA Method 3660A, to reduce matrix interferences caused by sulfur: SFOI-SludgeProfile (380-141535-1). The reagent lot number used was: 5963588. EPA 8082.

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

Pesticides Method 8081B: The native sample, matrix spike, and matrix spike duplicate (MS/MSD) associated with preparation batch 570-547455 and analytical batch 570-548304 were performed at the same dilution. Due to the additional level of analyte present in the spiked samples, the concentration of 4,4'-DDT in the MS/MSD was above the instrument calibration range. The data have been reported and qualified.

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 and precision for preparation batch 570-556098 and analytical batch 570-556411 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) precision was within acceptance limits.

Method 6010B - STLC Citrate: The method blank for preparation batch 570-547904 and 570-548650 and analytical batch 570-549179 contained < Barium> above the method detection limit. This target analyte concentration was less than the reporting limit (RL) in the method blank; therefore, re-extraction and/or re-analysis of samples was not performed.

Method 7471B: The matrix spike / matrix spike duplicate (MS/MSD) recoveries for preparation batch 570-548822 and analytical batch 570-549239 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.

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

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