The short answer

1 result is above the health goal. The worst: Lead, above the health goal. 1 health-based violation since 2016.

What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 2019 to 2026.

Copper: EPA’s file records a utility’s copper only when it exceeds the action level. The last here was 1.8 ppm, for the period ending Dec. 31, 2003. None since is on file, so it is not counted as a current finding.

Nitrate, arsenic, chromium (total) and fluoride: Massachusetts’s own results, samples taken from April 14, 2020 to Sept. 23, 2026, with EPA’s 2012 to 2019 file for earlier years.

Lead

Above the health goal

6.0ppb

90th percentile, 2026

In the latest period, 9 in 10 homes sampled were at or below 6.0 ppb, below EPA’s action level of 15 ppb. The action level drops to 10 ppb on Nov. 1, 2027. EPA’s health goal for lead is zero.

Nitrate

Below EPA’s limits

8.2ppm

Highest sample; found in 25 of 25

2026 average: 5.5 ppm

The highest sample, in 2023, was 8.2 ppm, below EPA’s legal limit of 10 ppm. In 2026, the latest year on file, its three samples averaged 5.5 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 7.2 ppm, in 2017.

What handles it

  • NSF/ANSI 58 look for “Nitrate/Nitrite Reduction”
  • NSF/ANSI 53 look for “Nitrate/Nitrite (30 ppm challenge)”

  • Fluoride

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.

Hardness

Hard, 126 mg/L (7.4 grains per gallon), at its one sampling point, 2023 to 2026.

Hardness is calcium and magnesium. EPA sets no limit for it: it shows up as scale on fixtures and in water heaters, and as soap that won’t lather. USGS calls water above 60 mg/L moderately hard, above 120 hard and above 180 very hard.

What this report can’t tell you

  • Everything else. Nitrate, arsenic, chromium (total) and fluoride results here are Massachusetts’s own from 2020 on, with EPA’s national file for 2012 to 2019. Old Farm Road Water Trust’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; Massachusetts’s results run from April 14, 2020 to Sept. 23, 2026.

Testing your own tap

Old Farm Road 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 Massachusetts certifies.
