The short answer
1 result is above EPA’s legal limit, and 3 more are above the health goal. The worst: Total trihalomethanes (TTHM), above the legal limit. 16 health-based violations since 2016.
What handles itWhat was found
PFAS: Pennsylvania’s own results under its PFAS rule, entry point samples taken from March 18, 2024 to Sept. 16, 2026.
Lead and copper: EPA SDWIS monitoring periods ending 1992 to 1998.
Total trihalomethanes (TTHM), haloacetic acids (HAA5), nitrate, fluoride, arsenic, chromium (total) and uranium: Pennsylvania’s own results, samples taken from March 11, 2020 to Sept. 14, 2026, with EPA’s 2012 to 2019 file for earlier years.
PFAS: PFOS, PFOA, PFHxS and PFBS were found, of the six PFAS in EPA’s 2024 drinking water rule; their results are below.
EPA’s 2024 PFAS rule, compound by compound
| PFAS | EPA’s limit | Result |
|---|---|---|
| PFOA | 4.0 ppt | Above the health goal2.5 ppt highest, found in 5 of 6 samples. Details |
| PFOS | 4.0 ppt | Above the health goal3.1 ppt highest, found in 6 of 6 samples. Details |
| PFHxS | 10 ppt | Below EPA’s limits0.84 ppt highest, found in 1 of 4 samples. Details |
| PFNA | 10 ppt | Not foundNot found in any of 4 samples |
| HFPO-DA (GenX) | 10 ppt | Not foundNot found in any of 4 samples |
| PFBS | Index only | Below EPA’s limits2.7 ppt highest, found in 3 of 4 samples. Details |
| 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.

Total trihalomethanes (TTHM)
Forms or is added in treatment
91ppb
Highest yearly average, 2020 to 2026
2026 average: 72.7 ppb
Averaged by year, the highest was 91 ppb, in 2023, above EPA’s legal limit of 80 ppb. Its highest single sample was 168 ppb. In 2026, the latest year on file, its three samples averaged 72.7 ppb. EPA recorded violations for total trihalomethanes (TTHM) at this utility in 2022, 2023 and 2024.

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: Trihalomethanes (TTHM) Reduction, PFOS Reduction, PFOA Reduction, Lead Reduction
For: Total trihalomethanes (TTHM), PFOS, PFOA, Lead
Other certifiers’ wording: VOC Reduction; Total PFAS Reduction; Perfluorooctane Sulfonate (PFOS); Perfluorooctanoic Acid (PFOA)
- NSF/ANSI 58
Claims: Trihalomethanes (TTHM) Reduction, Perfluorooctane Sulfonate (PFOS), Perfluorooctanoic Acid (PFOA), Lead Reduction
For: Total trihalomethanes (TTHM), PFOS, PFOA, 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.
