The short answer

1 result is above EPA’s legal limit. The worst: Copper, above the action level. No health-based violations on file since 2016.

What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 2005 to 2023.

Total trihalomethanes (TTHM), haloacetic acids (HAA5), nitrate and arsenic: New York’s yearly summaries per water system, 2020 to 2024, with EPA’s 2012 to 2019 file for earlier years.

Chromium (total), fluoride and uranium: EPA’s compliance monitoring file, samples taken from Aug. 1, 2013 to Dec. 23, 2019. Newer results are in the utility’s annual water quality report.

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.”

At the tap, or for the whole house?

Lead and copper usually come from pipes and fixtures inside or near your home. A whole-house system sits where water enters, so it cannot catch what your own plumbing adds after it. For those, the filter that counts is the one at the tap. How whole-house systems compare.

Violations since 2016

No health-based violations on file with EPA since 2016. There are 101 monitoring or reporting violations: a sample missed, late or not reported.

What this report can’t tell you

  • Everything else. Total trihalomethanes (TTHM), haloacetic acids (HAA5), nitrate and arsenic results here are New York’s own yearly summaries 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. Roxbury Water District’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; New York’s yearly summaries cover 2020 to 2024; EPA’s compliance samples are from Aug. 1, 2013 to Dec. 23, 2019.

Testing your own tap

Roxbury Water District’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 York certifies.

No lab New York certifies is within 75 miles of the area Roxbury Water District serves on the state’s list. Some take samples by mail; the state’s page lists them all.
