The short answer

1 result is above EPA’s legal limit, and 1 more is above the health goal. The worst: Nitrate, above the legal limit. 1 health-based violation since 2016.

What handles it

What was found

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

Nitrate, 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.

Arsenic, chromium (total) and fluoride: EPA’s compliance monitoring file, samples taken from Jan. 24, 2012 to Oct. 17, 2017. Newer results are in the utility’s annual water quality report.

Above the legal limit1

Nitrate

Comes from the source

Above the legal limit

13ppm

Highest sample; found in 33 of 33

2024 average: 3.4 ppm

The highest sample, in 2021, was 13 ppm, above EPA’s legal limit of 10 ppm. In 2024, the latest year on file, it averaged 3.4 ppm. EPA recorded a violation for nitrate at this utility in 2021. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 4.5 ppm, in 2017.

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

Above the health goal1

Lead

Comes from pipes, often your own

Above the health goal

5.0ppb

90th percentile, 2025

In the latest period, 9 in 10 homes sampled were at or below 5.0 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)

Below EPA’s limits

21.9ppb

Highest yearly average, 2020 to 2023

2023 average: 3.1 ppb

Averaged by year, the highest was 21.9 ppb, in 2021, below EPA’s legal limit of 60 ppb. In 2023, the latest year on file, it averaged 3.1 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 11 ppb, in 2013.

20.9ppb

Highest yearly average, 2020 to 2023

2023 average: 11.3 ppb

Averaged by year, the highest was 20.9 ppb, in 2021, below EPA’s legal limit of 80 ppb. In 2023, the latest year on file, it averaged 11.3 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 37.2 ppb, in 2013.

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: Nitrate/Nitrite (30 ppm challenge), Lead Reduction

    For: Nitrate, Lead

  • NSF/ANSI 58

    Claims: Nitrate/Nitrite Reduction, Lead Reduction

    For: Nitrate, Lead

    Other certifiers’ wording: Nitrate

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. Nitrate, 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. Arsenic, chromium (total) and fluoride come from EPA’s file alone, which ends in 2019. Clarksville 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 Jan. 24, 2012 to Oct. 17, 2017.

Testing your own tap

Clarksville 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.
