The short answer

1 result is above EPA’s legal limit, and 1 more is above the health goal. The worst: Total trihalomethanes (TTHM), above the legal limit. 12 health-based violations since 2016.

What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 2008 to 2025.

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

93.9ppb

Highest yearly average, 2020 to 2024

Averaged by year, the highest was 93.9 ppb, in 2024, above EPA’s legal limit of 80 ppb. Its highest single sample was 128 ppb. That was also the latest year on file. EPA recorded violations for total trihalomethanes (TTHM) at this utility in 2021 and 2022. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 109 ppb, in 2014, and EPA recorded violations in 2013, 2014, 2015, 2016, 2017, 2018 and 2019.

Above the health goal

1.5ppb

90th percentile, 2025

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.

29.6ppb

Highest yearly average, 2020 to 2024

2024 average: 24.5 ppb

Averaged by year, the highest was 29.6 ppb, in 2021, below EPA’s legal limit of 60 ppb. Its highest single sample was 46.7 ppb. In 2024, the latest year on file, it averaged 24.5 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 52 ppb, in 2018.

No certification claim covers this compound yet.

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: Trihalomethanes (TTHM) Reduction, Lead Reduction

    For: Total trihalomethanes (TTHM), Lead

    Other certifiers’ wording: VOC Reduction

  • NSF/ANSI 58

    Claims: Trihalomethanes (TTHM) Reduction, Lead Reduction

    For: Total trihalomethanes (TTHM), 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) and haloacetic acids (HAA5) results here are New York’s own yearly summaries from 2020 on, with EPA’s national file for 2012 to 2019. Dix Water District #1’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

Dix Water District #1’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 Dix Water District #1 serves on the state’s list. Some take samples by mail; the state’s page lists them all.
