Report Number: 180-126039-1

With the exceptions noted as flags or footnotes, standard analytical protocols were followed in the analysis of the samples and no problems were encountered or anomalies observed. In addition all laboratory quality control samples were within established control limits, with any exceptions noted below. Each sample was analyzed to achieve the lowest possible reporting limit within the constraints of the method. In some cases, due to interference or analytes present at high concentrations, samples were diluted. For diluted samples, the reporting limits are adjusted relative to the dilution required.

Calculations are performed before rounding to avoid round-off errors in calculated results.

All holding times were met and proper preservation noted for the methods performed on these samples, unless otherwise detailed in the individual sections below.

RECEIPT

The samples were received on 08/20/2021; the samples arrived in good condition, properly preserved and on ice. The temperatures of the 4 coolers at receipt time were 2.2º C, 2.9º C, 3.0º C and 4.1º C.

VOLATILES

Surrogate recovery for the following samples were outside control limits: #20210951 AMENDED COMPOSITE S/DISCRETE S-1 (180-126039-9), #20210952 AMENDED COMPOSITE T (180-126039-10), #20210953 AMENDED COMPOSITE U (180-126039-11), #20210954 AMENDED COMPOSITE V (180-126039-12), #20210955 AMENDED COMPOSITE W (180-126039-13), #20210956 AMENDED COMPOSITE X (180-126039-14), #20210957 AMENDED COMPOSITE Y (180-126039-15) and #20210958 AMENDED COMPOSITE Z (180-126039-16). Evidence of matrix interference is present; therefore, re-extraction and/or re-analysis was not performed. The pH of the samples was 12. High pH often results in low recovery of Dibromofluoromethane surrogate.

The laboratory control sample (LCS) for analytical batch 180-370374 recovered outside control limits for the following analytes:

1,2,4-Trichlorobenzene and Acrolein. These analytes were biased high in the LCS and were not detected in the associated samples;

therefore, the data have been reported.

The continuing calibration verification (CCV) analyzed in batch 180-370374 was outside the method criteria for the following analyte(s):

1,4-Dioxane RF, Vinyl chloride, 1,2,4-Trichlorobenzene and Chloromethane (LOW). A CCV standard at or below the reporting limit (RL) was analyzed with the affected samples and found to be acceptable. As indicated in the reference method, sample analysis may proceed; however, any detection for the affected analyte(s) is considered estimated.

The continuing calibration verification (CCV) analyzed in 180-370374 was outside the method criteria for the following analyte(s): Acrolein and 2-Butanone (HIGH). As indicated in the reference method, sample analysis may proceed; however, any detection for the affected analyte(s) is considered estimated.

The continuing calibration verification (CCV) analyzed in batch 180-368943 was outside the method criteria for the following analyte(s):

1,4-Dioxane RF, ,Bromoform, Trichloroethene, Trichlorofluoromethane, and 2-Hexanone. A CCV standard at or below the reporting limit (RL) was analyzed with the affected samples and found to be acceptable. As indicated in the reference method, sample analysis may proceed; however, any detection for the affected analyte(s) is considered estimated.

SEMIVOLATILES

All sediment samples were diluted due to the nature of the sample matrix. Elevated reporting limits (RLs) are provided.

Surrogate recovery for the following sample was outside control limits: #20210955 AMENDED COMPOSITE W (180-126039-13) and #20210956 AMENDED COMPOSITE X (180-126039-14). Evidence of matrix interference is present and the sample was analyzed at a dilution; therefore, re-extraction and/or re-analysis was not performed.

Naphthalene was detected in method blank LB 180-369295/1-F at a level exceeding the reporting limit. If the associated sample reported a result above the MDL and/or RL, the result has been flagged.

Caprolactam and Phenanthrene were detected in method blank LB 180-369612/1-F at levels that were above the method detection limit but below the reporting limit. The values should be considered estimates, and have been flagged. If the associated sample reported a result above the MDL and/or RL, the result has been flagged.

The RPD of the laboratory control sample (LCS) and laboratory control sample duplicate (LCSD) for preparation batch 180-370105 and analytical batch 180-370777 recovered outside control limits for the following analyte: 2,4-Dinitrophenol.

PESTICIDES

The following samples were diluted due to the nature of the sample matrix: #20210941 COMPOSITE T (180-126039-2), #20210942 COMPOSITE U (180-126039-3), #20210943 COMPOSITE V (180-126039-4), #20210944 COMPOSITE W (180-126039-5), #20210945

COMPOSITE X (180-126039-6), #20210946 COMPOSITE Y (180-126039-7), #20210947 COMPOSITE Z (180-126039-8), #20210951 AMENDED COMPOSITE S/DISCRETE S-1 (180-126039-9), #20210952 AMENDED COMPOSITE T (180-126039-10), #20210953 AMENDED COMPOSITE U (180-126039-11), #20210954 AMENDED COMPOSITE V (180-126039-12), #20210955 AMENDED COMPOSITE W (180-126039-13), #20210956 AMENDED COMPOSITE X (180-126039-14), #20210957 AMENDED COMPOSITE Y (180-126039-15) and #20210958 AMENDED COMPOSITE Z (180-126039-16). Elevated reporting limits (RLs) are provided.

The recovery is within acceptance limits on the other column, indicating that the extraction process was in control.

Compound trans-Chlordane eluted slightly outside the retention time window on the MR-1 column for the following samples: #20210951 AMENDED COMPOSITE S/DISCRETE S-1 (180-126039-9), #20210952 AMENDED COMPOSITE T (180-126039-10), #20210953 AMENDED COMPOSITE U (180-126039-11), #20210954 AMENDED COMPOSITE V (180-126039-12), #20210955 AMENDED COMPOSITE W (180-126039-13), #20210956 AMENDED COMPOSITE X (180-126039-14), #20210957 AMENDED COMPOSITE Y (180-126039-15) and #20210958 AMENDED COMPOSITE Z (180-126039-16). This retention time shift was taken into account when reviewing the sample(s) for target compounds. This compound confirmed on the MR-2 column.

alpha-BHC is being reported with an "E" qualifier. This LCS/SRM is a known value and a dilution was not performed.

The continuing calibration verification (CCV) associated with batch 371152 recovered outside acceptance criteria, low biased, for trans-Chlordane on both columns. A reporting limit (RL) standard was analyzed, and the target analyte was detected. Since the associated samples were non-detect for this analyte, the data have been reported.

The continuing calibration verification (CCV) associated with batch 371632 recovered above the upper control limit for Toxaphene on the MR-1 column. The samples associated with this CCV were non-detects for the affected analytes; therefore, the data have been reported.

The associated sample is impacted: (CCV 180-371632/2).

The continuing calibration verification (CCV) associated with 371632 recovered high and outside the control limits for cis-Chlordane on the MR-1 column. Results are confirmed on both columns and reported from the passing MR-2 column. The associated sample is:

(CCVIS 180-371632/6).

The continuing calibration verification (CCV) associated with batch 371632 recovered above the upper control limit for Toxaphene on the MR-1 column. The samples associated with this CCV were non-detects for the affected analytes; therefore, the data have been reported.

The associated sample is impacted: (CCV 180-371632/28).

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

HERBICIDES

Surrogate recovery for the following sample was outside control limits: #20210942 COMPOSITE U (180-126039-3). Evidence of matrix interference is present; therefore, re-extraction and/or re-analysis was not performed.
