The short answer

2 results are above EPA’s legal limit. The worst: Lead, above the action level. 2 health-based violations since 2016.

What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 1993.

Arsenic, nitrate, total trihalomethanes (TTHM) and uranium: New Hampshire’s yearly averages per water system, as CDC’s Environmental Public Health Tracking Network publishes them, 2020 to 2023.

Fluoride: EPA’s violation records from 2020 on, with EPA’s 2012 to 2019 file for earlier years.

Chromium (total): EPA’s compliance monitoring file, samples taken from Jan. 26, 2015 to Jan. 22, 2018. Newer results are in the utility’s annual water quality report.

Above the legal limit2

Lead

Comes from pipes, often your own

Above the action level

20ppb

90th percentile, 1993

In the latest period, 9 in 10 homes sampled were at or below 20 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

Fluoride

Forms or is added in treatment

Above the legal limit

5.0ppm

Limit violation, 2025

EPA recorded two violations of the legal limit for fluoride at this utility in 2024 and 2025. The highest measured level, for July 1, 2025 to June 30, 2026, was an average of 5.0 ppm, above EPA’s legal limit of 4.0 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 1.2 ppm, in 2018.

2.2ppb

Highest yearly average, 2015 to 2018

Averaged by year, the highest was 2.2 ppb, in 2018, below EPA’s legal limit of 100 ppb. That was also the latest year on file.

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, Fluoride

    For: Lead, Fluoride

  • NSF/ANSI 58

    Claims: Lead Reduction, Fluoride Reduction

    For: Lead, Fluoride

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. Arsenic, nitrate, total trihalomethanes (TTHM) and uranium results here are New Hampshire’s yearly averages as CDC publishes them, from 2020 on, with EPA’s national file for 2012 to 2019. Chromium (total) comes from EPA’s file alone, which ends in 2019. Riversbend’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 Jan. 26, 2015 to Jan. 22, 2018.

Testing your own tap

Riversbend’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.
