The short answer
1 result is above EPA’s legal limit. The worst: Arsenic, above the legal limit. 8 health-based violations since 2016.
What handles itWhat was found
Arsenic, total trihalomethanes (TTHM), haloacetic acids (HAA5), nitrate and uranium: 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. 3, 2015 to Jan. 2, 2019. Newer results are in the utility’s annual water quality report.
Above the legal limit1
Arsenic
Comes from the source
15.5ppb
Highest yearly average, 2020 to 2023
2023 average: 13 ppb
Averaged by year, the highest was 15.5 ppb, in 2022, above EPA’s legal limit of 10 ppb. In 2023, the latest year on file, it averaged 13 ppb, above the limit. EPA recorded violations for arsenic at this utility in 2022 and 2023. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 8.0 ppb, in 2015, and EPA recorded a violation in 2012.

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, total trihalomethanes (TTHM), haloacetic acids (HAA5), nitrate 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. Fluoride and chromium (total) come from EPA’s file alone, which ends in 2019. Freedom Hill/Pine Ridge Est’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. 3, 2015 to Jan. 2, 2019.
