The short answer

1 result is above the limit’s level with no violation recorded, and 2 more are above the health goal. The worst: Haloacetic acids (HAA5), above the limit’s level, no violation. No health-based violations on file since 2016.

What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 2002 to 2024.

Haloacetic acids (HAA5), arsenic, total trihalomethanes (TTHM) and nitrate: New York’s yearly summaries per water system, 2020 to 2024, with EPA’s 2012 to 2019 file for earlier years.

Chromium (total) and fluoride: EPA’s compliance monitoring file, samples taken from July 9, 2013 to June 16, 2019. Newer results are in the utility’s annual water quality report.

Above the limit’s level, no violation recorded1

Haloacetic acids (HAA5)

Forms or is added in treatment

Above the limit’s level, no violation

89.2ppb

Highest yearly average, 2020 to 2024

2024 average: 14 ppb

Averaged by year, the highest was 89.2 ppb, in 2023, above EPA’s legal limit of 60 ppb. Its highest single sample was 158 ppb. In 2024, the latest year on file, it averaged 14 ppb. EPA judges this limit on running averages at each sampling point, and recorded no violation for haloacetic acids (HAA5) at this utility since 2020. Results like these with no violation often include water sampled before treatment or blending; the utility’s annual report says what reaches the tap. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 12.1 ppb, in 2014.

Above the health goal2

Arsenic

Above the health goal

3.3ppb

Highest yearly average, 2022

Averaged by year, the highest was 3.3 ppb, in 2022: below EPA’s legal limit of 10 ppb, but above its health goal of zero. That is the only year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 3.8 ppb, in 2013.

Lead

Above the health goal

1.6ppb

90th percentile, 2022 to 2024

In the latest period, 9 in 10 homes sampled were at or below 1.6 ppb, below EPA’s action level of 15 ppb. The action level drops to 10 ppb on Nov. 1, 2027. EPA’s health goal for lead is zero.

77.4ppb

Highest yearly average, 2020 to 2024

2024 average: 29.5 ppb

Averaged by year, the highest was 77.4 ppb, in 2023, below EPA’s legal limit of 80 ppb. Its highest single sample was 122 ppb. In 2024, the latest year on file, it averaged 29.5 ppb. EPA recorded no violation for total trihalomethanes (TTHM) at this utility since 2020. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 37.7 ppb, in 2014.

Highest sample; found in 4 of 5

2024 average: 0.35 ppm

The highest sample, in 2022, was 0.43 ppm, below EPA’s legal limit of 10 ppm. In 2024, the latest year on file, it averaged 0.35 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 0.84 ppm, in 2012.

What handles it

A certification covers specific claims, not a whole standard. Look for these claims on the certifier’s listing, not the box. Wording varies a little: NSF writes “Lead Reduction,” WQA just “Lead.”

  • NSF/ANSI 53

    Claims: Arsenic (Pentavalent)<=50 ppb Reduction, Lead Reduction

    For: Arsenic, Lead

    Other certifiers’ wording: Arsenic (III) (50 ppb influent level)

  • NSF/ANSI 58

    Claims: Arsenic (Pentavalent)<=50 ppb Reduction, Lead Reduction

    For: Arsenic, Lead

    Other certifiers’ wording: Arsenic (Pentavalent)<=300 ppb Reduction; Arsenic (V) (300 ppb influent level)

At the tap, or for the whole house?

Lead and copper usually come from pipes and fixtures inside or near your home. A whole-house system sits where water enters, so it cannot catch what your own plumbing adds after it. For those, the filter that counts is the one at the tap. How whole-house systems compare.

What this report can’t tell you

  • Everything else. Haloacetic acids (HAA5), arsenic, total trihalomethanes (TTHM) and nitrate results here are New York’s own yearly summaries from 2020 on, with EPA’s national file for 2012 to 2019. Chromium (total) and fluoride come from EPA’s file alone, which ends in 2019. Corbett Community Corp.’s own annual report, which it must send you every year, has newer results for those and the contaminants this page does not show.

  • Your own plumbing. Lead results are the 90th percentile across homes the utility samples. Your home’s service line, solder and fixtures decide yours. A certified lab test is the only way to know.

  • What it means for your health. This page reports what the records show and EPA’s limits and goals; it is not medical advice. If you are worried about a health effect, talk to a doctor or your local health department.

  • Anything after the latest data. SDWIS data is from 2026 Q3; UCMR 5 didn’t sample this utility; New York’s yearly summaries cover 2020 to 2024; EPA’s compliance samples are from July 9, 2013 to June 16, 2019.

Testing your own tap

Corbett Community Corp.’s results are for the water it sends out. What your own service line, solder and fixtures add shows up only in a test of your tap, by a lab New York certifies.
