The short answer

2 results are above the health goal. The worst: Uranium, above the health goal. 1 health-based violation since 2016.

What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 2012 to 2024.

Uranium, nitrate, fluoride, arsenic and chromium (total): Massachusetts’s own results, samples taken from June 3, 2020 to April 8, 2026, with EPA’s 2012 to 2019 file for earlier years.

Above the health goal2

Uranium

Comes from the source

Above the health goal

22.5ppb

Highest yearly average, 2022 to 2025

2025, one sample: 22.2 ppb

Averaged by year, the highest was 22.5 ppb, in 2022: below EPA’s legal limit of 30 ppb, but above its health goal of zero. In 2025, the latest year on file, its one sample was 22.2 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 20.7 ppb, in 2019.

What handles it

Lead

Comes from pipes, often your own

Above the health goal

0.7ppb

90th percentile, 2022 to 2024

In the latest period, 9 in 10 homes sampled were at or below 0.7 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.

What handles it

Below EPA’s limits2

Nitrate

Comes from the source

Below EPA’s limits

1.9ppm

Highest sample; found in 7 of 7

2026, one sample: 1.9 ppm

The highest sample, in 2026, was 1.9 ppm, below EPA’s legal limit of 10 ppm. That was also the latest year on file, and its one sample was 1.9 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 2.4 ppm, in 2014.

Highest yearly average, 2020 to 2026

2026: not found

Averaged by year, the highest was 0.1 ppm, in 2020, below EPA’s legal limit of 4.0 ppm. In 2026, the latest year on file, it wasn’t found in its one sample. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 0.2 ppm, in 2013.

What handles it

2 compounds tested and not foundBelow the reporting level in every sample. Not found is not the same as zero.
  • Arsenic
  • Chromium (total)

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

Very hard, 399 mg/L (23.3 grains per gallon), at its one sampling point, 2015 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. Uranium, nitrate, fluoride, arsenic and chromium (total) results here are Massachusetts’s own from 2020 on, with EPA’s national file for 2012 to 2019. Pine Hill Condominium’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 June 3, 2020 to April 8, 2026.

Testing your own tap

Pine Hill Condominium’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.
