497592 on 2/27/2026Report ID

Enclosed are the analytical results for samples received by the laboratory on Feb 10, 2026.

The ALS Environmental laboratory in Middletown, Pennsylvania is a National Environmental Laboratory Accreditation Program (NELAP) accredited laboratory and as such, certifies that all applicable test results meet the requirements of NELAP.

If you have any questions regarding this certificate of analysis, please contact Stacey Welk (Project Coordinator) at (717) 944-5541.

Analyses were performed according to our laboratory’s NELAP-approved quality assurance program and any applicable state requirements.

The test results meet requirements of the current NELAP standards or state requirements, where applicable. For a specific list of accredited analytes, refer to the certifications section of the ALS website at www.alsglobal.com/en/Our-Services/Life-Sciences/Environmental/Downloads.

Notes

Samples collected by ALS personnel are done so in accordance with the procedures set forth in the ALS Field Sampling Plan (20 - Field

Services Sampling Plan).

Except as qualified, Clean Water Act sample analyses are consistent with methodology requirements in 40 CFR Part 136, including but not limited to the following EPA Method reference revisions:

EPA 300.1 Rev. 1.0-1997

EPA 300.0 Rev. 2.1-1993

EPA 353.2 Rev. 2.0-1993

EPA 410.4 Rev. 1.0-1993

EPA 420.4 Rev. 1.0-1993

EPA 365.1 Rev. 2.0-1993

EPA 200.7 Rev. 4.4-1994

EPA 200.8 Rev. 5.4-1994

EPA 245.1 Rev. 3.0-1994

Except as qualified, Safe Drinking Water Act sample analyses are consistent with methodology requirements in 40 CFR Part 141.

The Chain of Custody document is included as part of this report.

All Library Search analytes should be regarded as tentative identifications based on the presumptive evidence of the mass spectra.

Concentrations reported are estimated values.

Parameters identified as "analyze immediately" require analysis within 15 minutes of collection. Any "analyze immediately" parameters not listed under the header "Field Parameters" are preformed in the laboratory and are therefore analyzed out of hold time.

Method references listed on this report beginning with the prefix “S” followed by a method number (such as S2310B-97) refer to methods from “Standard Methods for the Examination of Water and Wastewater”.

For microbiological analyses, the "Prepared" value is the date/time into the incubator and the "Analyzed" value is the date/time out the incubator.

An Analysis-Prep Method Cross Reference Table is included after Analytical Results & Qualifiers section in this report.

Unless otherwise noted, all quantitative results for soils are reported on a dry weight basis.

The pH analysis is an "analyze immediately" analysis. Parameters identified as "analyze immediately" require analysis within 15 minutes of collection, and are therefore analyzed outside of the method holding time when analyzed in the laboratory.

This sample was analyzed at a temperature of 19.2 degrees Celsius.2
