The short answer

2 results are above the health goal. The worst: Uranium, above the health goal. No health-based violations on file since 2016.

What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 2010 to 2024.

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

Uranium, chromium (total) and fluoride: EPA’s compliance monitoring file, samples taken from July 29, 2014 to Oct. 16, 2017. Newer results are in the utility’s annual water quality report.

Above the health goal2

Uranium

Comes from the source

Above the health goal

3.4ppb

Highest yearly average, 2017

Averaged by year, the highest was 3.4 ppb, in 2017: below EPA’s legal limit of 30 ppb, but above its health goal of zero. That is the only year on file.

What handles it

Lead

Comes from pipes, often your own

Above the health goal

1.5ppb

90th percentile, 2022 to 2024

In the latest period, 9 in 10 homes sampled were at or below 1.5 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.

Below EPA’s limits3

Total trihalomethanes (TTHM)

Below EPA’s limits

27.5ppb

Highest yearly average, 2022 to 2023

Averaged by year, the highest was 27.5 ppb, in 2023, below EPA’s legal limit of 80 ppb. That was also the latest year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 24.2 ppb, in 2019.

Haloacetic acids (HAA5)

Forms or is added in treatment

Below EPA’s limits

12ppb

Highest yearly average, 2022

Averaged by year, the highest was 12 ppb, in 2022, below EPA’s legal limit of 60 ppb. That is the only year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 8.4 ppb, in 2016.

Highest sample; found in 5 of 5

2024 average: 0.32 ppm

The highest sample, in 2023, was 0.45 ppm, below EPA’s legal limit of 10 ppm. In 2024, the latest year on file, it averaged 0.32 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 0.34 ppm, in 2018.

What handles it

  • NSF/ANSI 58 look for “Nitrate/Nitrite Reduction”
  • NSF/ANSI 53 look for “Nitrate/Nitrite (30 ppm challenge)”

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.”

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. Total trihalomethanes (TTHM), haloacetic acids (HAA5), nitrate and arsenic results here are New York’s own yearly summaries from 2020 on, with EPA’s national file for 2012 to 2019. Uranium, chromium (total) and fluoride come from EPA’s file alone, which ends in 2019. Sackett Lake Estates’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 29, 2014 to Oct. 16, 2017.

Testing your own tap

Sackett Lake Estates’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.
