Definitions and Other Information

Analyte is not certified or the state of the samples origination does not offer certification for the Analyte.

MCL

The Maximum Contaminant Level (MCL) is the maximum concentration of a chemical that is allowed in public drinking water systems. The MCL is established by the U.S. Environmental Protection Agency (EPA). Some states have MCLs that are equal to or less than the Federally established MCL. The listed MCL value reflects the MCL established by the State where the sample was taken.

General Notes for

The RLs and MDLs (Reporting Limit and Method Detection Limit respectively) reported are adjusted for any dilution necessary due to the levels of target and/or non-target analytes and matrix interference. The RL(REPORTING LIMIT) is based upon the lowest standard utilized for the calibration where applicable.
Samples are retained for a period of thirty days after submittal of report, unless other arrangements are made.
York's liability for the above data is limited to the dollar value paid to York for the referenced project.
This report shall not be reproduced without the written approval of York Analytical Laboratories, Inc.
All analyses conducted met method or Laboratory SOP requirements. See the Sample and Data Qualifiers Section for further information.
It is noted that no analyses reported herein were subcontracted to another laboratory, unless noted in the report.
This report reflects results that relate only to the samples submitted on the attached chain-of-custody form(s) received by York.

MCL The Maximum Contaminant Level (MCL) is the maximum concentration of a chemical that is allowed in public drinking water systems. The MCL is established by the U.S. Environmental Protection Agency (EPA). Some states have MCLs that are equal to or less than the Federally established MCL. The listed MCL value reflects the MCL established by the State where the sample was taken. ## **General Notes for N5E0475** 1. The RLs and MDLs (Reporting Limit and Method Detection Limit respectively) reported are adjusted for any dilution necessary due to the levels of target and/or non-target analytes and matrix interference. The RL(REPORTING LIMIT) is based upon the lowest standard utilized for the calibration where applicable. 2. Samples are retained for a period of thirty days after submittal of report, unless other arrangements are made. 3. York's liability for the above data is limited to the dollar value paid to York for the referenced project. 4. This report shall not be reproduced without the written approval of York Analytical Laboratories, Inc. 5. All analyses conducted met method or Laboratory SOP requirements. See the Sample and Data Qualifiers Section for further information. 6. It is noted that no analyses reported herein were subcontracted to another laboratory, unless noted in the report. 7. This report reflects results that relate only to the samples submitted on the attached chain-of-custody form(s) received by York. ## **Approved By:** Cassie Mosher Chemistry Director Phil Murphy Interim Microbiology Director **==> picture [152 x 36] intentionally omitted <==** **==> picture [156 x 3031] intentionally omitted <==** **Date:** May 2123, 2025 56 Church Hill Road #2 (203) 270-9973 Newtown, CT 06470 FAX (203) 270-3348 ClientServices@yorklab.com Page 6 of 7 www.YORKLAB.com Page 7 of 7

MCL The Maximum Contaminant Level (MCL) is the maximum concentration of a chemical that is allowed in public drinking water systems. The MCL is established by the U.S. Environmental Protection Agency (EPA). Some states have MCLs that are equal to or less than the Federally established MCL. The listed MCL value reflects the MCL established by the State where the sample was taken. ## **General Notes for N5E0475** 1. The RLs and MDLs (Reporting Limit and Method Detection Limit respectively) reported are adjusted for any dilution necessary due to the levels of target and/or non-target analytes and matrix interference. The RL(REPORTING LIMIT) is based upon the lowest standard utilized for the calibration where applicable. 2. Samples are retained for a period of thirty days after submittal of report, unless other arrangements are made. 3. York's liability for the above data is limited to the dollar value paid to York for the referenced project. 4. This report shall not be reproduced without the written approval of York Analytical Laboratories, Inc. 5. All analyses conducted met method or Laboratory SOP requirements. See the Sample and Data Qualifiers Section for further information. 6. It is noted that no analyses reported herein were subcontracted to another laboratory, unless noted in the report. 7. This report reflects results that relate only to the samples submitted on the attached chain-of-custody form(s) received by York. ## **Approved By:** Cassie Mosher Chemistry Director Phil Murphy Interim Microbiology Director **==> picture [152 x 36] intentionally omitted <==** **==> picture [156 x 3130] intentionally omitted <==** **Date:** May 2330, 2025 56 Church Hill Road #2 (203) 270-9973 Newtown, CT 06470 FAX (203) 270-3348 ClientServices@yorklab.com Page 6 of 7 www.YORKLAB.com Page 7 of 7

2025-05-01York Lab Technical Report — Wastewater 2025 (N5E0269, collected 05/07/2025)
— pinned to version dated 2025-05-01
Both documents are the same York Lab technical report (Project N5E0269, Wastewater 2025) for samples collected 05/07/2025, with Document B appearing to be a reformatted or reissued version of Document A on the same date.
2025-05-01York Lab Technical Report — Wastewater 2025 (N5E0833, collected 05/28/2025)
— pinned to version dated 2025-05-01
Both are separate York Lab technical reports on different wastewater samples (different York Project IDs: N5E0269 vs N5E0833, collected on different dates), each a distinct analytical work product, not revisions of the same singular report.
2025-05-01York Lab Technical Report — Village of Red Hook (N5E0475, collected 05/14/2025)
— pinned to version dated 2025-05-01
Both documents are the same York Lab technical report (Project N5E0475) for Village of Red Hook water samples collected 05/14/2025, with Document B appearing to be a reformatted or reprocessed version of Document A on the same date.
2025-05-01York Lab Technical Report — Village of Red Hook Wastewater (N5E0683, collected 05/21/2025)
— pinned to version dated 2025-05-01
Both documents are the same York Lab technical report (N5E0683) for Village of Red Hook Wastewater samples collected 05/21/2025, with Document B appearing to be a complete or revised version of Document A from the same analytical work.
2025-07-14Mayor's Report — June 2025
Two separate laboratory reports on the same project with different sample batches, collection dates, and York project numbers (N5E0269 vs N5E0833); each is an independent analytical work product, not a revision of the same singular decision or document.
2025-07-14York Lab Technical Report — May 21, 2025 (Project N5E0683)
Both are separate technical reports from York Lab on different projects (N5E0269 vs N5E0683) with different collection dates and client project IDs, not revisions of the same singular instrument.
2025-07-14York Lab Technical Report — May 7, 2025 (Project N5E0269)
Both documents are the same York Lab technical report (Project N5E0269, dated 05/21/2025) for the Village of Red Hook wastewater analysis, with identical sample data and methodology; the two board filings on the same day (2025-07-14) represent the same underlying lab report artifact in different presentation contexts.
2025-07-14York Lab Technical Report — May 28, 2025 (Project N5E0833)
Two separate technical reports on different York projects (N5E0269 vs N5E0833) with different collection dates and client project IDs, linked only by shared topic area (wastewater analysis).
2025-07-14York Lab Technical Report — May 14, 2025 (Project N5E0475)
Two separate technical reports on different wastewater projects (Wastewater 2025 vs. Project N5E0475) with different York project numbers, sample IDs, and collection dates; they are distinct board artifacts that happen to share a topic area (water quality), not revisions of the same singular decision or instrument.
