The short answer

Nothing in EPA’s and Massachusetts’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

Nitrate: Massachusetts’s own results, samples taken from Oct. 19, 2022 to Oct. 14, 2025, with EPA’s 2012 to 2019 file for earlier years.

Fluoride, arsenic and chromium (total): EPA’s compliance monitoring file, samples taken from Oct. 1, 2014 to Oct. 12, 2017. Newer results are in the utility’s annual water quality report.

What this report can’t tell you

Everything else. Nitrate results here are Massachusetts’s own from 2022 on, with EPA’s national file for 2012 to 2019. Fluoride, arsenic and chromium (total) come from EPA’s file alone, which ends in 2019. Quabbin Sunrise Cooperative Inc’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; Massachusetts’s results run from Oct. 19, 2022 to Oct. 14, 2025; EPA’s compliance samples are from Oct. 1, 2014 to Oct. 12, 2017.

Testing your own tap

Quabbin Sunrise Cooperative Inc’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 Massachusetts certifies.
