The short answer

3 results are above the health goal. The worst: PFOA, above the health goal. No health-based violations on file since 2016.

What handles it

What was found

PFAS: Pennsylvania’s own results under its PFAS rule, entry point samples taken from March 24, 2025 to Nov. 13, 2025.

Nitrate, total trihalomethanes (TTHM), arsenic, chromium (total), fluoride and haloacetic acids (HAA5): Pennsylvania’s own results, samples taken from May 15, 2020 to May 14, 2026, with EPA’s 2012 to 2019 file for earlier years.

Uranium: EPA’s compliance monitoring file, samples taken from Dec. 15, 2014 to April 12, 2018. Newer results are in the utility’s annual water quality report.

PFAS: PFOA and PFOS 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.

PFOA

Above the health goal

3.3ppt

Highest sample, Aug. 14, 2025; found in 4 of 8

2025 average: 1.6 ppt

The highest sample was 3.3 ppt: below EPA’s new limit of 4.0 ppt, which takes effect in 2029, but above its health goal of zero. Averaged over four quarters at one entry point, the way both Pennsylvania’s limit and EPA’s are judged, the highest was 3.1 ppt, for the year to Dec. 31, 2025: below Pennsylvania’s limit of 14 ppt and below EPA’s new limit of 4.0 ppt. Its only year on file is 2025, when its eight samples averaged 1.6 ppt.

2025 average: 1.4 ppt

The highest sample was 3.0 ppt: below EPA’s new limit of 4.0 ppt, which takes effect in 2029, but above its health goal of zero. Averaged over four quarters at one entry point, the way both Pennsylvania’s limit and EPA’s are judged, the highest was 2.8 ppt, for the year to Dec. 31, 2025: below Pennsylvania’s limit of 18 ppt and below EPA’s new limit of 4.0 ppt. Its only year on file is 2025, when its eight samples averaged 1.4 ppt.

2018: not found

Averaged by year, the highest was 0.22 ppb, in 2014: below EPA’s legal limit of 30 ppb, but above its health goal of zero. Its highest single sample was 0.23 ppb. In 2018, the latest year on file, it wasn’t found in any of its six samples.

Highest sample; found in 14 of 14

2026 average: 2.5 ppm

The highest sample, in 2023, was 3.0 ppm, below EPA’s legal limit of 10 ppm. In 2026, the latest year on file, its two samples averaged 2.5 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 2.9 ppm, in 2012.

Highest yearly average, 2021 to 2024

Averaged by year, the highest was 3.3 ppb, in 2024, below EPA’s legal limit of 80 ppb. Its highest single sample was 5.3 ppb. That was also the latest year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 3.5 ppb, in 2017.

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.”

  • NSF/ANSI 53

    Claims: PFOA Reduction, PFOS Reduction

    For: PFOA, PFOS

    Other certifiers’ wording: Total PFAS Reduction; Perfluorooctanoic Acid (PFOA); Perfluorooctane Sulfonate (PFOS)

  • NSF/ANSI 58

    Claims: Perfluorooctanoic Acid (PFOA), Perfluorooctane Sulfonate (PFOS), Uranium

    For: PFOA, PFOS, Uranium

At the tap, or for the whole house?

These come with the water itself, so a whole-house system certified for the same claims treats every tap and shower. A filter at the tap treats drinking water for much less. How whole-house systems compare.

What this report can’t tell you

  • Everything else. Nitrate, total trihalomethanes (TTHM), arsenic, chromium (total), fluoride and haloacetic acids (HAA5) results here are Pennsylvania’s own from 2020 on, with EPA’s national file for 2012 to 2019. Uranium comes from EPA’s file alone, which ends in 2019. Solebury School’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; Pennsylvania’s results run from May 15, 2020 to May 14, 2026; EPA’s compliance samples are from Dec. 15, 2014 to April 12, 2018; Pennsylvania’s PFAS results run from March 24, 2025 to Nov. 13, 2025.

Testing your own tap

Solebury School’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.
