The short answer

1 result is above the health goal. The worst: Lead, above the health goal. 4 health-based violations since 2016.

What handles it

What was found

PFAS: Pennsylvania’s own results under its PFAS rule, entry point samples taken from March 26, 2024 to Sept. 29, 2026.

Lead and copper: EPA SDWIS monitoring periods ending 1993 to 2007.

Total trihalomethanes (TTHM), haloacetic acids (HAA5), nitrate, fluoride, arsenic, chromium (total) and uranium: Pennsylvania’s own results, samples taken from March 10, 2020 to Sept. 22, 2026, with EPA’s 2012 to 2019 file for earlier years.

PFAS: None of the six PFAS in EPA’s 2024 drinking water rule was found in this utility’s samples. None of the other 12 PFAS tested for was found either.

Results from Pennsylvania’s own PFAS monitoring, samples where water enters the pipes; each compound’s card has its four-quarter averages, the way limits are judged. The limits are EPA’s 2024 rule, with compliance due from 2029; EPA has since proposed changes to some of them, explained on each compound’s page. Pennsylvania’s own limits for PFOA and PFOS are in force now. PFBS has no limit of its own and counts only toward EPA’s Hazard Index, which TapBuff works out only from UCMR 5’s averages, so it isn’t given here.

Above the health goal1

Lead

Comes from pipes, often your own

Above the health goal

3.0ppb

90th percentile, 2007

In the latest period, 9 in 10 homes sampled were at or below 3.0 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.

Below EPA’s limits

65.1ppb

Highest yearly average, 2020 to 2026

2026 average: 38.8 ppb

Averaged by year, the highest was 65.1 ppb, in 2021, below EPA’s legal limit of 80 ppb. Its highest single sample was 134 ppb. In 2026, the latest year on file, its six samples averaged 38.8 ppb. EPA recorded no violation for total trihalomethanes (TTHM) at this utility since 2020. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 61.8 ppb, in 2013.

2026 average: 29.2 ppb

Averaged by year, the highest was 29.5 ppb, in 2025, below EPA’s legal limit of 60 ppb. Its highest single sample was 55.7 ppb. In 2026, the latest year on file, its nine samples averaged 29.2 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 57.5 ppb, in 2018, and EPA recorded violations in 2018 and 2019.

0.37ppm

Highest sample; found in 3 of 13

2026: not found

The highest sample, in 2022, was 0.37 ppm, below EPA’s legal limit of 10 ppm. In 2026, the latest year on file, it wasn’t found in any of its two samples. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 0.73 ppm, in 2012.

Highest yearly average, 2020 to 2026

2026: not found

Averaged by year, the highest was 0.12 ppm, in 2021, below EPA’s legal limit of 4.0 ppm. Its highest single sample was 0.13 ppm. In 2026, the latest year on file, it wasn’t found in any of its two samples.

What handles it

21 compounds tested and not foundIncluding all six PFAS in EPA’s 2024 rule. Below the reporting level in every sample. Not found is not the same as zero.

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.

What this report can’t tell you

  • Everything else. Total trihalomethanes (TTHM), haloacetic acids (HAA5), nitrate, fluoride, arsenic, chromium (total) and uranium results here are Pennsylvania’s own from 2020 on, with EPA’s national file for 2012 to 2019. Mansfield University’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; Pennsylvania’s results run from March 10, 2020 to Sept. 22, 2026; Pennsylvania’s PFAS results run from March 26, 2024 to Sept. 29, 2026.

Testing your own tap

Mansfield University’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 Pennsylvania certifies.
