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 this report can’t tell you

  • Everything else. Total trihalomethanes (TTHM) and haloacetic acids (HAA5) results here are Rhode Island’s yearly averages as CDC publishes them, from 2020 on, with EPA’s national file for 2012 to 2019. United States Navy - Fort Adams’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 Rhode Island cover 2020 to 2023.

Testing your own tap

United States Navy - Fort Adams’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 Rhode Island certifies.
