The short answer

1 result is above EPA’s legal limit, and 1 more is above the health goal. The worst: Haloacetic acids (HAA5), above the legal limit. 5 health-based violations since 2016.

What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 2002 to 2006.

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

Above the legal limit

56.8ppb

Highest yearly average, 2020 to 2024

2024 average: 47.6 ppb

Averaged by year, the highest was 56.8 ppb, in 2021, below EPA’s legal limit of 60 ppb. Its highest single sample was 77.5 ppb. In 2024, the latest year on file, it averaged 47.6 ppb. EPA judges this limit at each sampling point, and recorded a violation for haloacetic acids (HAA5) at this utility in 2020. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 70.9 ppb, in 2019, and EPA recorded a violation in 2019.

Above the health goal

11ppb

90th percentile, 2006

In the latest period, 9 in 10 homes sampled were at or below 11 ppb, below EPA’s action level of 15 ppb. The action level drops to 10 ppb on Nov. 1, 2027, and this result is at or above that. EPA’s health goal for lead is zero.

Below EPA’s limits

65.3ppb

Highest yearly average, 2020 to 2024

2024 average: 56.9 ppb

Averaged by year, the highest was 65.3 ppb, in 2022, below EPA’s legal limit of 80 ppb. Its highest single sample was 105 ppb. In 2024, the latest year on file, it averaged 56.9 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 78.9 ppb, in 2013.

What handles it

  • NSF/ANSI 53 look for “Trihalomethanes (TTHM) Reduction”
  • NSF/ANSI 58 look for “Trihalomethanes (TTHM) Reduction”

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. Haloacetic acids (HAA5) and total trihalomethanes (TTHM) results here are New York’s own yearly summaries from 2020 on, with EPA’s national file for 2012 to 2019. Wyoming Correctional’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

Wyoming Correctional’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 Wyoming Correctional serves on the state’s list. Some take samples by mail; the state’s page lists them all.
