The short answer

Nothing in EPA’s and CDC’s records for this utility is above a health goal. That covers nitrate, arsenic and other regulated chemicals, plus lead and copper, not everything. No health-based violations on file since 2016.

What was found

Copper: EPA’s file records a utility’s copper only when it exceeds the action level. The last here was 5.1 ppm, for the period ending Dec. 31, 1993. None since is on file, so it is not counted as a current finding.

Nitrate, total trihalomethanes (TTHM), arsenic, haloacetic acids (HAA5) 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.

Chromium (total) and fluoride: EPA’s compliance monitoring file, samples taken from Oct. 13, 2014 to Dec. 4, 2017. Newer results are in the utility’s annual water quality report.

Below EPA’s limits

5.1ppm

Highest yearly average, 2020 to 2023

2023 average: 4.5 ppm

Averaged by year, the highest was 5.1 ppm, in 2021, below EPA’s legal limit of 10 ppm. In 2023, the latest year on file, it averaged 4.5 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 5.3 ppm, in 2014.

What this report can’t tell you

  • Everything else. Nitrate, total trihalomethanes (TTHM), arsenic, haloacetic acids (HAA5) 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) and fluoride come from EPA’s file alone, which ends in 2019. Pinehaven Water Trust’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 Oct. 13, 2014 to Dec. 4, 2017.

Testing your own tap

Pinehaven Water Trust’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.
