The short answer

1 result is above EPA’s legal limit, and 2 more are above the health goal. The worst: Copper, above the action level. No health-based violations on file since 2016.

What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 2015 to 2023.

Arsenic, haloacetic acids (HAA5), 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.

Fluoride, chromium (total) and uranium: EPA’s compliance monitoring file, samples taken from Dec. 10, 2012 to Aug. 20, 2019. Newer results are in the utility’s annual water quality report.

Above the legal limit1

Copper

Comes from pipes, often your own

Above the action level

2.0ppm

90th percentile, 2021 to 2023

In the latest period, 9 in 10 homes sampled were at or below 2.0 ppm, above EPA’s action level of 1.3 ppm.

What handles it

Above the health goal2

Arsenic

Comes from the source

Above the health goal

1.9ppb

Highest yearly average, 2020 to 2024

2024 average: 0.55 ppb

Averaged by year, the highest was 1.9 ppb, in 2022: below EPA’s legal limit of 10 ppb, but above its health goal of zero. In 2024, the latest year on file, it averaged 0.55 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 0.3 ppb, in 2017.

What handles it

  • NSF/ANSI 58 look for “Arsenic (Pentavalent)<=50 ppb Reduction”
  • NSF/ANSI 53 look for “Arsenic (Pentavalent)<=50 ppb Reduction”

Lead

Comes from pipes, often your own

Above the health goal

2.0ppb

90th percentile, 2025

In the latest period, 9 in 10 homes sampled were at or below 2.0 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.

Haloacetic acids (HAA5)

Forms or is added in treatment

Below EPA’s limits

44.9ppb

Highest yearly average, 2020 to 2023

2023 average: 23 ppb

Averaged by year, the highest was 44.9 ppb, in 2022, below EPA’s legal limit of 60 ppb. In 2023, the latest year on file, it averaged 23 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 29 ppb, in 2015.

Highest yearly average, 2020 to 2023

2023 average: 20 ppb

Averaged by year, the highest was 48.1 ppb, in 2022, below EPA’s legal limit of 80 ppb. In 2023, the latest year on file, it averaged 20 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 40.5 ppb, in 2019.

Nitrate

Comes from the source

Below EPA’s limits

1.2ppm

Highest sample; found in 6 of 6

2024 average: 0.19 ppm

The highest sample, in 2020, was 1.2 ppm, below EPA’s legal limit of 10 ppm. In 2024, the latest year on file, it averaged 0.19 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 3.1 ppm, in 2012.

What handles it

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

Fluoride

Forms or is added in treatment

Below EPA’s limits

0.12ppm

Highest yearly average, 2012 to 2019

2019: not found

Averaged by year, the highest was 0.12 ppm, in 2016, below EPA’s legal limit of 4.0 ppm. In 2019, the latest year on file, it wasn’t found in its one sample.

What handles it

Chromium (total)

Comes from the source

Below EPA’s limits

2.4ppb

Highest yearly average, 2012 to 2019

2019: not found

Averaged by year, the highest was 2.4 ppb, in 2018, below EPA’s legal limit of 100 ppb. Its highest single sample was 4.7 ppb. In 2019, the latest year on file, it wasn’t found in its one sample.

What handles it

One compound tested and not foundBelow the reporting level in every sample. Not found is not the same as zero.
  • Uranium

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

    For: Copper, Arsenic, Lead

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

  • NSF/ANSI 58

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

    For: Copper, 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. Arsenic, haloacetic acids (HAA5), 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. Fluoride, chromium (total) and uranium come from EPA’s file alone, which ends in 2019. Bluestone Acres MHP’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 Dec. 10, 2012 to Aug. 20, 2019.

Testing your own tap

Bluestone Acres MHP’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.
