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, not everything. No health-based violations on file since 2016.

What was found

Arsenic and nitrate: New Hampshire’s yearly averages per water system, as CDC’s Environmental Public Health Tracking Network publishes them, 2020 to 2022.

Chromium (total), fluoride and uranium: EPA’s compliance monitoring file, samples taken from Jan. 20, 2015 to July 19, 2018. Newer results are in the utility’s annual water quality report.

What this report can’t tell you

  • Everything else. Arsenic and nitrate 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), fluoride and uranium come from EPA’s file alone, which ends in 2019. Canterbury Spruces Housing’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 2022; EPA’s compliance samples are from Jan. 20, 2015 to July 19, 2018.

Testing your own tap

Canterbury Spruces Housing’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.
