The short answer

1 result is above EPA’s legal limit, and 2 more are above the health goal. The worst: Lead, above the action level. 1 health-based violation since 2016.

What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 2006 to 2007.

Uranium, arsenic, 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 and chromium (total): EPA’s compliance monitoring file, samples taken from Feb. 11, 2014 to Oct. 23, 2019. Newer results are in the utility’s annual water quality report.

Above the legal limit1

Lead

Comes from pipes, often your own

Above the action level

16ppb

90th percentile, 2007

In the latest period, 9 in 10 homes sampled were at or below 16 ppb, above 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.

What handles it

Above the health goal2

Uranium

Comes from the source

Above the health goal

23.1ppb

Highest yearly average, 2020 to 2023

2023 average: 20.8 ppb

Averaged by year, the highest was 23.1 ppb, in 2020: below EPA’s legal limit of 30 ppb, but above its health goal of zero. In 2023, the latest year on file, it averaged 20.8 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 24 ppb, in 2014.

What handles it

Arsenic

Comes from the source

Above the health goal

3.1ppb

Highest yearly average, 2021 to 2023

2023 average: 2.5 ppb

Averaged by year, the highest was 3.1 ppb, in 2021: below EPA’s legal limit of 10 ppb, but above its health goal of zero. In 2023, the latest year on file, it averaged 2.5 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 3.4 ppb, in 2016.

Below EPA’s limits1

Fluoride

Forms or is added in treatment

Below EPA’s limits

3.8ppm

Highest yearly average, 2014 to 2019

2019 average: 3.7 ppm

Averaged by year, the highest was 3.8 ppm, in 2016, below EPA’s legal limit of 4.0 ppm. Its highest single sample was 3.9 ppm. In 2019, the latest year on file, its four samples averaged 3.7 ppm.

  • 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.”

  • NSF/ANSI 53

    Claims: Lead Reduction, Arsenic (Pentavalent)<=50 ppb Reduction

    For: Lead, Arsenic

    Other certifiers’ wording: Arsenic (III) (50 ppb influent level)

  • NSF/ANSI 58

    Claims: Lead Reduction, Uranium, Arsenic (Pentavalent)<=50 ppb Reduction

    For: Lead, Uranium, Arsenic

    Other certifiers’ wording: Arsenic (Pentavalent)<=300 ppb Reduction; Arsenic (V) (300 ppb influent level)

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. Uranium, arsenic, 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 and chromium (total) come from EPA’s file alone, which ends in 2019. Forest Edge’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 Feb. 11, 2014 to Oct. 23, 2019.

Testing your own tap

Forest Edge’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.
