The short answer

1 result is 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

Copper: EPA’s file records a utility’s copper only when it exceeds the action level. The last here was 1.8 ppm, for the period ending Dec. 31, 2006. None since is on file, so it is not counted as a current finding.

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 and chromium (total): EPA’s compliance monitoring file, samples taken from Feb. 6, 2012 to July 10, 2019. Newer results are in the utility’s annual water quality report.

Above the health goal1

Arsenic

Comes from the source

Above the health goal

0.5ppb

Highest yearly average, 2020 to 2024

2024: not found

Averaged by year, the highest was 0.5 ppb, in 2023: below EPA’s legal limit of 10 ppb, but above its health goal of zero. In 2024, the latest year on file, it wasn’t found. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 0.8 ppb, in 2016.

What handles it

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

Below EPA’s limits4

Haloacetic acids (HAA5)

Forms or is added in treatment

Below EPA’s limits

24.8ppb

Highest yearly average, 2020 to 2024

2024 average: 22.3 ppb

Averaged by year, the highest was 24.8 ppb, in 2023, below EPA’s legal limit of 60 ppb. Its highest single sample was 34 ppb. In 2024, the latest year on file, it averaged 22.3 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 31.8 ppb, in 2018.

Total trihalomethanes (TTHM)

Forms or is added in treatment

Below EPA’s limits

29.8ppb

Highest yearly average, 2020 to 2024

2024 average: 29 ppb

Averaged by year, the highest was 29.8 ppb, in 2023, below EPA’s legal limit of 80 ppb. Its highest single sample was 42 ppb. In 2024, the latest year on file, it averaged 29 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 49.9 ppb, in 2012.

Nitrate

Comes from the source

Below EPA’s limits

1.1ppm

Highest sample; found in 2 of 5

2024 average: 1.1 ppm

The highest sample, in 2024, was 1.1 ppm, below EPA’s legal limit of 10 ppm. That was also the latest year on file, and it averaged 1.1 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 0.038 ppm, in 2016.

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

0.062ppm

Highest yearly average, 2012 to 2019

2019, one sample: 0.059 ppm

Averaged by year, the highest was 0.062 ppm, in 2015, below EPA’s legal limit of 4.0 ppm. Its highest single sample was 0.12 ppm. In 2019, the latest year on file, its one sample was 0.059 ppm.

What handles it

2 compounds tested and not foundBelow the reporting level in every sample. Not found is not the same as zero.
  • Chromium (total)
  • Lead

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

    Claim: Arsenic (Pentavalent)<=50 ppb Reduction

    For: Arsenic

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

  • NSF/ANSI 58

    Claim: Arsenic (Pentavalent)<=50 ppb Reduction

    For: Arsenic

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

At the tap, or for the whole house?

These come with the water itself, so a whole-house system certified for the same claims treats every tap and shower. A filter at the tap treats drinking water for much less. 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 and chromium (total) come from EPA’s file alone, which ends in 2019. Bolton Water District’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 Feb. 6, 2012 to July 10, 2019.

Testing your own tap

Bolton Water District’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.
