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. No health-based violations on file since 2016.
What handles itWhat was found
PFAS: Pennsylvania’s own results under its PFAS rule, entry point samples taken from July 28, 2023 to Sept. 24, 2026.
Lead and copper: EPA SDWIS monitoring periods ending 1993 to 1996.
Arsenic, uranium, total trihalomethanes (TTHM), nitrate, haloacetic acids (HAA5), chromium (total) and fluoride: Pennsylvania’s own results, samples taken from March 9, 2020 to Aug. 10, 2026, with EPA’s 2012 to 2019 file for earlier years.
PFAS: PFOS, PFOA, PFHxS, PFNA and PFBS were found, of the six PFAS in EPA’s 2024 drinking water rule; their results are below. Two other PFAS with no federal limit were found, the highest PFHxA at 4.4 ppt: see them below.

| PFBS | Index only | Below EPA’s limits6.3 ppt highest, found in 17 of 30 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.
Above the legal limit1
PFOS
Comes from the source
22ppt
Highest sample, Feb. 6, 2024; found in 31 of 36
2026 average: 2.0 ppt
The highest sample was 22 ppt, about 5.5 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 17.8 ppt, for the year to Dec. 31, 2024: below Pennsylvania’s limit of 18 ppt and above EPA’s new limit of 4.0 ppt. Pennsylvania recorded two violations of its limit for PFOS here, dated July 31, 2024 and Nov. 12, 2024, on running averages of 19 to 21 ppt. In 2026, the latest year on file, its nine samples averaged 2.0 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.”
- NSF/ANSI 53
Claims: PFOS Reduction, PFOA Reduction, Arsenic (Pentavalent)<=50 ppb Reduction, Lead Reduction
For: PFOS, PFOA, Arsenic, Lead
Other certifiers’ wording: Total PFAS Reduction; Perfluorooctane Sulfonate (PFOS); Perfluorooctanoic Acid (PFOA); Arsenic (III) (50 ppb influent level)
- NSF/ANSI 58
Claims: Perfluorooctane Sulfonate (PFOS), Perfluorooctanoic Acid (PFOA), Arsenic (Pentavalent)<=50 ppb Reduction, Uranium, Lead Reduction
For: PFOS, PFOA, Arsenic, Uranium, Lead
Other certifiers’ wording: Arsenic (Pentavalent)<=300 ppb Reduction; Arsenic (V) (300 ppb influent level)
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, uranium, total trihalomethanes (TTHM), nitrate, haloacetic acids (HAA5), chromium (total) and fluoride results here are Pennsylvania’s own from 2020 on, with EPA’s national file for 2012 to 2019. Bcwsa New Hope’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.
