The short answer

1 result is above EPA’s legal limit, 1 more is above EPA’s new limit, which takes effect in 2029, and 3 more are above the health goal. The worst: PFOS, above Pennsylvania’s limit. 1 health-based violation since 2016.

What was found

PFAS: Pennsylvania’s own results under its PFAS rule, entry point samples taken from Feb. 20, 2024 to Sept. 18, 2026.

Lead and copper: EPA SDWIS monitoring periods ending 1993 to 1996.

Arsenic, nitrate, total trihalomethanes (TTHM), haloacetic acids (HAA5), chromium (total), fluoride and uranium: Pennsylvania’s own results, samples taken from April 6, 2020 to Sept. 18, 2026, with EPA’s 2012 to 2019 file for earlier years.

PFAS: PFOS, PFHxS, PFOA and PFBS were found, of the six PFAS in EPA’s 2024 drinking water rule; their results are below.

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.

About PFAS certifications

NSF’s PFAS claims are tested to below 20 ppt. EPA’s limit is 4.0 ppt, and EPA says no certification yet shows a filter reaching its levels.

PFOS

Comes from the source

Above Pennsylvania’s limit

44.7ppt

Highest sample, March 7, 2024; found in 28 of 34

2026 average: 16.3 ppt

The highest sample was 44.7 ppt, about 11 times EPA’s new limit of 4.0 ppt, which takes effect in 2029. EPA’s health goal is zero. Compliance will be judged on a running annual average, not one sample. Averaged over four quarters at one entry point, the way both Pennsylvania’s limit and EPA’s are judged, the highest was 34.1 ppt, for the year to Sept. 30, 2025: above Pennsylvania’s limit of 18 ppt and above EPA’s new limit of 4.0 ppt. Pennsylvania recorded 15 violations of its limit for PFOS here, dated Oct. 22, 2024, Feb. 10, 2025, April 23, 2025 and 5 more dates, on running averages of 19 to 34 ppt. In 2026, the latest year on file, its nine samples averaged 16.3 ppt.

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.”

    For: PFOS, PFHxS, PFOA, Lead, Arsenic

    Claims: Perfluorooctane Sulfonate (PFOS), Perfluorooctanoic Acid (PFOA), Lead Reduction, Arsenic (Pentavalent)<=50 ppb Reduction

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. Arsenic, nitrate, total trihalomethanes (TTHM), haloacetic acids (HAA5), chromium (total), fluoride and uranium results here are Pennsylvania’s own from 2020 on, with EPA’s national file for 2012 to 2019. Muni Auth of Boro of Matamoras’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 April 6, 2020 to Sept. 18, 2026; Pennsylvania’s PFAS results run from Feb. 20, 2024 to Sept. 18, 2026.

Testing your own tap

Muni Auth of Boro of Matamoras’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.
