Did any MCL violation occur? If so, please describe:

Did an emergency or low pressure problem occur? Did source water bypass an existing treatment process in the system? If so, please explain.

added chlorine manually to storage tanks to maintain residual in distribution while trouble shooting chloine injector and feed line issues

Comments:

injection quill for sodium hypochlorite discovered to be clogged with build up of CaCO3 7/8 - 7/11, back pressure caused rupture of chlorine feed line; replaced line, repiped injection point, ordered

replacement chlorine quill, added chlorine manually to storage tanks to maintain residual in distribution. Note-CaCO3 blockage had to be physically removed; adding physical quill inspection to

routine maintenance items as new operator will be taking over 8/1/2025. Replacement quill will be removable to allow for inspection, original injector was hard piped with no ability for inspection.

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 July 23, 2025 and listed below. The project was identified as your project: Village of Red Hook .

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

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

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.
