The ZIP code it serves
The short answer
1 result is above EPA’s legal limit, and 1 more is above the health goal. The worst: Fluoride, above the legal limit. 16 health-based violations since 2016.
What handles itWhat was found
Uranium, nitrate, arsenic 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.
Fluoride: EPA’s violation records from 2020 on.
Above the legal limit1
Fluoride
Forms or is added in treatment
4.2ppm
Limit violation, 2022
EPA recorded four violations of the legal limit for fluoride at this utility in 2022 and 2023. The highest measured level, for July 1, 2022 to Sept. 30, 2022, was an average of 4.2 ppm, above EPA’s legal limit of 4.0 ppm.
What handles it
- NSF/ANSI 58 look for “Fluoride Reduction”
- NSF/ANSI 53 look for “Fluoride”
Above the health goal1
Uranium
Comes from the source
9.2ppb
Highest yearly average, 2022
Averaged by year, the highest was 9.2 ppb, in 2022: below EPA’s legal limit of 30 ppb, but above its health goal of zero. That is the only year on file.
What handles it
- NSF/ANSI 58 look for “Uranium”
Below EPA’s limits1
Nitrate
Comes from the source
0.24ppm
Highest yearly average, 2023
Averaged by year, the highest was 0.24 ppm, in 2023, below EPA’s legal limit of 10 ppm. That is the only year on file.
What handles it
- NSF/ANSI 58 look for “Nitrate/Nitrite Reduction”
- NSF/ANSI 53 look for “Nitrate/Nitrite (30 ppm challenge)”
2 compounds tested and not foundBelow the reporting level in every sample. Not found is not the same as zero.
- 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.”
- NSF/ANSI 53
Claim: Fluoride
For: Fluoride
- NSF/ANSI 58
Claims: Fluoride Reduction, Uranium
For: Fluoride, Uranium
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. Uranium, nitrate, arsenic 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. Rolling Ridge’s own annual report, which it must send you every year, has 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.
