Purpose and Results

This report contains the analytical data for the sample(s) identified on the attached chain-of-custody received in our laboratory on May 28, 2025 and listed below. The project was identified as your project: Wastewater 2025 .

The analyses were conducted utilizing appropriate EPA, Standard Methods, and ASTM methods as detailed in the data summary tables.

All samples were received in proper condition meeting the customary acceptance requirements for environmental samples except those indicated under the Sample and Analysis Qualifiers section of this report.

All analyses met the method and laboratory standard operating procedure requirements except as indicated by any data flags, the meaning of which are explained in the Sample and Data Qualifiers Relating to This Work Order section of this report and case narrative if applicable.

Please contact Client Services at 203-270-9973 with any questions regarding this report.

Definitions and Other Information

TNTC Too numerous to count

HT-01 This result was reported from an analysis conducted outside of the EPA recommended holding time.

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 N5E0833

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.

Village of Red Hook ~ Village Green Committee ~ Monthly Report ’ ' January 2025 Spring Planting planning is underway, if you are interested in having trees planted, please reach out. We are looking to add trees to any of our village streets so if you are out and about a see an open space maybe in front of new or old businesses you can send those suggestions to us as well. We are actively recruiting members. If you are interested in giving back to your community but don’t have a lot of time to give this may be the perfect committee for you! Village of Red Hook Y Sewer Department ' Monthly Report ‘ 1 January 2025 In January we worked hard to continue to address the issues that the WWTP has been having. We had received our report back from the Audit that had been scheduled the previous month. Unfortunately, there were several areas of concern, even after the “food dump” in December, that came out of the audit. The audit was thorough and documented many facets of the state of the wastewater treatment plant, processes in place, etc. Based on the report from the project manager we worked on a priority list and slowly have been working to rectify and fix each area we can as quickly as possible – some of which is on an operational standpoint and others are mechanical. Systems had been down and are waiting on parts to fix completely. Additionally, as we think about the expansion, we been working with the Senior Project Manager to provide detailed SOPs for our Wastewater Treatment Operator to follow. The Board also voted to send out an RFP for our WWTP and our Water systems. We continue to have conversations at the department level of what makes the most sense. Additionally, mid-January the team met with a representative from New York Rural Water Association who has experience with sewer code and functionality of WWTPs in general. We are seeking out the experts in the field to continue to help guide us in this endeavor. We are sympathetic to the concerns that this under operating plant has caused and that is why we are actively working to try to fix and repair what has been done and to implement process along that way to hopefully prevent this from happening again. We meet every other Friday. If you have concerns about the expansion and/or are currently in the Sewer Use Area and have comments, concerns, etc. please do not hesitate to reach out. There is also the expression of interest form up on our website if you are wanting to connect into the sewer (capacity required). It will put you on our list of places to consider and puts you on our radar. Village of Red Hook Y Speed Limit Initiative ' Monthly Report ‘1 January 2025 ‘ We are waiting to hear back from the Engineering team about tackling a portion of the report around the School Zone separately from the overall Village speed limit so that we can move forward. Village of Red Hook ~ Town of Red Hook Greenway and Trails Committee ’ Monthly Report ’ ' January 2025 The meeting met on the second Thursday of the month at Town Hall. The committee picked up where it had left off in November continuing to discuss signage along the trails, new blazing projects with Winnakee Land Trust, as well as wanting to collaborate to create alternative or safer pathways into the village from the neighborhoods just next to it. Village of Red Hook i Climate Smart Communities Monthly Report ‘ 1 January 2025 We tabled at the recent Repair Café announcing that the Compost program will be launching soon. This had a lot of community engagement and residents seem to be excited about this program coming directly to the Village Center.

2025-05-01York Lab Technical Report — Wastewater 2025 (N5E0833, collected 05/28/2025)
— pins a specific version of this chain
Both are technical reports on the same project but separated by ~5 years with different collection/report dates; they are distinct artifacts, not revisions of each other.
2025-07-14York Lab Technical Report — Wastewater 2025 (N5E0833) — May 28, 2025 samples
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).
2025-07-14Mayor's Report — June 2025
Both documents are the same York Lab technical report (Project N5E0833, Wastewater 2025) for samples collected May 28, 2025, with identical content and same-day filing dates; Document B appears to be a complete or revised version of Document A.
2025-07-14York Lab Technical Report — Wastewater 2025 (N5E0269) — May 7, 2025 samples
Two distinct York Lab technical reports on different projects (N5E0269 vs N5E0833) with different sample dates and client project IDs; they are separate analytical work products, not revisions of the same instrument.
