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

Arsenic, haloacetic acids (HAA5), nitrate and total trihalomethanes (TTHM): New Hampshire’s yearly averages per water system, as CDC’s Environmental Public Health Tracking Network publishes them, 2020 to 2023, with EPA’s 2012 to 2019 file for earlier years.

Fluoride, chromium (total) and uranium: EPA’s compliance monitoring file, samples taken from June 18, 2014 to April 10, 2017. Newer results are in the utility’s annual water quality report.

Above the health goal1

Arsenic

Comes from the source

Above the health goal

4.0ppb

Highest yearly average, 2020 to 2023

2023: not found

Averaged by year, the highest was 4.0 ppb, in 2020: below EPA’s legal limit of 10 ppb, but above its health goal of zero. In 2023, the latest year on file, it wasn’t found. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 5.0 ppb, in 2014.

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 limits5

Haloacetic acids (HAA5)

Forms or is added in treatment

Below EPA’s limits

8.0ppb

Highest yearly average, 2022

Averaged by year, the highest was 8.0 ppb, in 2022, below EPA’s legal limit of 60 ppb. That is the only year on file.

Fluoride

Below EPA’s limits

0.45ppm

Highest yearly average, 2014 to 2017

2017, one sample: 0.41 ppm

Averaged by year, the highest was 0.45 ppm, in 2014, below EPA’s legal limit of 4.0 ppm. In 2017, the latest year on file, its one sample was 0.41 ppm.

What handles it

Nitrate

Below EPA’s limits

1.0ppm

Highest yearly average, 2020 to 2023

Averaged by year, the highest was 1.0 ppm, in 2023, below EPA’s legal limit of 10 ppm. That was also the latest year on file.

What handles it

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

Chromium (total)

Comes from the source

Below EPA’s limits

5.0ppb

Highest yearly average, 2014 to 2017

2017, one sample: 3.0 ppb

Averaged by year, the highest was 5.0 ppb, in 2014, below EPA’s legal limit of 100 ppb. In 2017, the latest year on file, its one sample was 3.0 ppb.

What handles it

Total trihalomethanes (TTHM)

Forms or is added in treatment

Below EPA’s limits

3.1ppb

Highest yearly average, 2020 to 2023

2023 average: 3.0 ppb

Averaged by year, the highest was 3.1 ppb, in 2022, below EPA’s legal limit of 80 ppb. In 2023, the latest year on file, it averaged 3.0 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 7.7 ppb, in 2016.

What handles it

  • NSF/ANSI 53 look for “Trihalomethanes (TTHM) Reduction”
  • NSF/ANSI 58 look for “Trihalomethanes (TTHM) Reduction”
One compound tested and not foundBelow the reporting level in every sample. Not found is not the same as zero.
  • Uranium

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), nitrate and total trihalomethanes (TTHM) results here are New Hampshire’s yearly averages as CDC publishes them, from 2020 on, with EPA’s national file for 2012 to 2019. Fluoride, chromium (total) and uranium come from EPA’s file alone, which ends in 2019. Lamplighter Estates’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 2020 to 2023; EPA’s compliance samples are from June 18, 2014 to April 10, 2017.

Testing your own tap

Lamplighter Estates’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.
