The short answer

1 result is above the health goal. The worst: Uranium, above the health goal. No health-based violations on file since 2016.

What handles it

What was found

Nitrate and total trihalomethanes (TTHM): New Hampshire’s yearly averages per water system, as CDC’s Environmental Public Health Tracking Network publishes them, 2022 to 2023, with EPA’s 2012 to 2019 file for earlier years.

Uranium, fluoride, chromium (total) and arsenic: EPA’s compliance monitoring file, samples taken from April 10, 2018 to Jan. 3, 2019. Newer results are in the utility’s annual water quality report.

Above the health goal1

Uranium

Comes from the source

Above the health goal

2.8ppb

Highest yearly average, 2018 to 2019

Averaged by year, the highest was 2.8 ppb, in 2019: below EPA’s legal limit of 30 ppb, but above its health goal of zero. That was also the latest year on file.

What handles it

Below EPA’s limits3

Nitrate

Comes from the source

Below EPA’s limits

4.4ppm

Highest yearly average, 2022 to 2023

Averaged by year, the highest was 4.4 ppm, in 2023, below EPA’s legal limit of 10 ppm. That was also the latest year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 1.3 ppm, in 2019.

What handles it

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

Fluoride

Below EPA’s limits

0.98ppm

Highest yearly average, 2018

Averaged by year, the highest was 0.98 ppm, in 2018, below EPA’s legal limit of 4.0 ppm. That is the only year on file.

What handles it

Chromium (total)

Comes from the source

Below EPA’s limits

1.4ppb

Highest yearly average, 2018

Averaged by year, the highest was 1.4 ppb, in 2018, below EPA’s legal limit of 100 ppb. That is the only year on file.

What handles it

  • Arsenic
  • Total trihalomethanes (TTHM)

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?

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.

Filters with those claims on a certifier’s listing

None of the filters TapBuff has checked so far carry these claims. Search the certifier listings for the claim above.

What this report can’t tell you

  • Everything else. Nitrate and total trihalomethanes (TTHM) results here are New Hampshire’s yearly averages as CDC publishes them, from 2022 on, with EPA’s national file for 2012 to 2019. Uranium, fluoride, chromium (total) and arsenic come from EPA’s file alone, which ends in 2019. Connor Court’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; CDC’s yearly averages for New Hampshire cover 2022 to 2023; EPA’s compliance samples are from April 10, 2018 to Jan. 3, 2019.

Testing your own tap

Connor Court’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 Hampshire certifies.
