The short answer

2 results are above the health goal. The worst: Arsenic, 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 2007 to 2026.

Arsenic, total trihalomethanes (TTHM), haloacetic acids (HAA5), nitrate and uranium: New York’s yearly summaries per water system, 2020 to 2024.

Above the health goal2

Arsenic

Comes from the source

Above the health goal

1.5ppb

Highest yearly average, 2020 to 2023

2023: not found

Averaged by year, the highest was 1.5 ppb, in 2020: below EPA’s legal limit of 10 ppb, but above its health goal of zero. In 2023, the latest year on file, it wasn’t found.

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

1.0ppb

90th percentile, 2026

In the latest period, 9 in 10 homes sampled were at or below 1.0 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.

What handles it

Below EPA’s limits3

Total trihalomethanes (TTHM)

Forms or is added in treatment

Below EPA’s limits

4.2ppb

Highest yearly average, 2020 to 2023

2023 average: 3.4 ppb

Averaged by year, the highest was 4.2 ppb, in 2022, below EPA’s legal limit of 80 ppb. Its highest single sample was 4.3 ppb. In 2023, the latest year on file, it averaged 3.4 ppb.

  • NSF/ANSI 58 look for “Trihalomethanes (TTHM) Reduction”

Haloacetic acids (HAA5)

Forms or is added in treatment

Below EPA’s limits

2.2ppb

Highest yearly average, 2020 to 2022

2022 average: 2.1 ppb

Averaged by year, the highest was 2.2 ppb, in 2021, below EPA’s legal limit of 60 ppb. Its highest single sample was 4.2 ppb. In 2022, the latest year on file, it averaged 2.1 ppb.

What handles it

Nitrate

Comes from the source

Below EPA’s limits

0.17ppm

Highest sample; found in 2 of 4

2024: not found

The highest sample, in 2023, was 0.17 ppm, below EPA’s legal limit of 10 ppm. In 2024, the latest year on file, it wasn’t found.

What handles it

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

Violations since 2016

No health-based violations on file with EPA since 2016. There are 106 monitoring or reporting violations: a sample missed, late or not reported.

What this report can’t tell you

  • Everything else. Arsenic, total trihalomethanes (TTHM), haloacetic acids (HAA5), nitrate and uranium results here are New York’s own yearly summaries from 2020 on, with EPA’s national file for 2012 to 2019. Blackburne Water Corp’s own annual report, which it must send you every year, has 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.

Testing your own tap

Blackburne Water 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.

No lab New York certifies is within 75 miles of the area Blackburne Water Corp serves on the state’s list. Some take samples by mail; the state’s page lists them all.
