Job Narrative 660-146568-1

The analytical test results presented in this report meet all requirements of the associated regulatory program listed on the Accreditation/Certification Summary Page, unless otherwise noted. Data qualifiers and/or narrative comments are included to explain any exceptions, if applicable. Regulated compliance samples (e.g. SDWA, NPDES) must comply with associated agency requirements/permits.

· Matrix-specific batch QC (e.g., MS, MSD, SD) may not be reported when insufficient sample volume is available or when site-specific QC samples are not submitted. In such cases, a Laboratory Control Sample Duplicate (LCSD) may be analyzed to provide precision data for the batch.

· For samples analyzed using surrogate and/or isotope dilution analytes, any recoveries falling outside of established acceptance criteria are re-prepared and/or re-analyzed to confirm results, unless the deviation is due to sample dilution or otherwise explained in the case narrative.

Receipt The sample was received on 12/8/2025 1:30 PM. 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 2.7°C.

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

General Chemistry Method 1664A_NP: Insufficient sample volume was available to perform a matrix spike/matrix spike duplicate/sample duplicate (MS/MSD/DUP) associated with analytical batch 670-192264.

Method 1664A_NP: A deviation from the Standard Operating Procedure (SOP) occurred. Details are as follows: Full volume not used due to sample matrix. Bottle not rinsed. Raw Leachate - NWTS (northwest transfer station) (660-146568-1)

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

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