Hall Environmental Analysis Laboratory received 2 sample(s) on 11/18/2021 for the analyses presented in the following report.

Andy Freeman

These were analyzed according to EPA procedures or equivalent. To access our accredited tests please go to www.hallenvironmental.com or the state specific web sites.

In order to properly interpret your results, it is imperative that you review this report in its entirety. See the sample checklist and/or the Chain of Custody for information regarding the sample receipt temperature and preservation. Data qualifiers or a narrative will be provided if the sample analysis or analytical quality control parameters require a flag.

When necessary, data qualifiers are provided on both the sample analysis report and the

QC summary report, both sections should be reviewed. All samples are reported, as received, unless otherwise indicated. Lab measurement of analytes considered field parameters that require analysis within 15 minutes of sampling such as pH and residual chlorine are qualified as being analyzed outside of the recommended holding time.

Please don't hesitate to contact HEAL for any additional information or clarifications.

Raw data reports are processed and reviewed by the analyst using the TargetLynx software package.

Calibration Information

Initial Calibration All initial calibration requirements have been met for this sample delivery group (SDG).

Page 6 of 20 Work Order: 19090

Continuing Calibration Verification (CCV) Requirements All associated calibration verification standard(s) (CVS) met the acceptance criteria.

Quality Control (QC) Information

Certification Statement The test results presented in this document are certified to meet all requirements of the 2009 TNI Standard.

Method Blank (MB) Statement The MB(s) analyzed with this SDG met the acceptance criteria.

Surrogate Recoveries All surrogate recoveries were within the established acceptance criteria for this SDG.

Laboratory Control Sample (LCS) Recovery The LCS spike recoveries met the acceptance limits.

Laboratory Control Sample Duplicate (LCSD) Recovery The LCSD spike recoveries met the acceptance limits.

LCS/LCSD Relative Percent Difference (RPD) Statement The RPD(s) between the LCS and LCSD met the acceptance limits.

QC Sample Designation A matrix spike and matrix spike duplicate analysis was not required for this SDG.

Technical Information

Receipt Temperature Samples were received within temperature requirements.

Holding Time Specifications CFA assigns holding times based on the associated methodology, which assigns the date and time from sample collection. Those holding times expressed in hours are calculated in the AlphaLIMS system. Those holding times expressed as days expire at midnight on the day of expiration. All samples in this SDG met the specified holding time.

Preparation/Analytical Method Verification All procedures were performed as stated in the SOP.

Sample Dilutions The samples in this SDG did not require dilutions.

Sample Re-extraction/Re-analysis Re-extractions or re-analyses were not required in this SDG.

Miscellaneous Information

Manual Integrations Certain standards and QC samples required manual integrations to correctly position the baseline as set in the calibration standard injections. Where manual integrations were performed, copies of all manual integration peak profiles are included in the raw data section of this fraction.

Manual integrations were required for data files in this SDG.
