The short answer
2 results are above EPA’s new limit, which takes effect in 2029, and 2 more are above the health goal. The worst: PFOA, above EPA’s new limit (2029). 3 health-based violations since 2016.
What handles itWhat was found
PFAS: Pennsylvania’s own results under its PFAS rule, entry point samples taken from Feb. 22, 2024 to July 30, 2026.
Uranium, arsenic, total trihalomethanes (TTHM), nitrate, haloacetic acids (HAA5), chromium (total) and fluoride: Pennsylvania’s own results, samples taken from Feb. 24, 2020 to Sept. 24, 2026, with EPA’s 2012 to 2019 file for earlier years.
PFAS: PFOA, PFOS 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 EPA’s new limit (2029)11 ppt highest, found in 22 of 22 samples. Details |
| PFOS | 4.0 ppt | Above EPA’s new limit (2029)7.1 ppt highest, found in 11 of 22 samples. Details |
| PFHxS | 10 ppt | Not foundNot found in any of 16 samples |
| PFNA | 10 ppt | Not foundNot found in any of 16 samples |
| HFPO-DA (GenX) | 10 ppt | Not foundNot found in any of 16 samples |
| PFBS | Index only | Below EPA’s limits18 ppt highest, found in 16 of 16 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 EPA’s new limit, which takes effect in 20292
PFOA
Comes from the source
11ppt
Highest sample, Oct. 30, 2024; found in 22 of 22
2026 average: 6.3 ppt
The highest sample was 11 ppt, about 2.8 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 9.5 ppt, for the year to March 31, 2025: below Pennsylvania’s limit of 14 ppt and above EPA’s new limit of 4.0 ppt. In 2026, the latest year on file, its three samples averaged 6.3 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.”
- NSF/ANSI 53
Claims: PFOA Reduction, PFOS Reduction, Arsenic (Pentavalent)<=50 ppb Reduction
For: PFOA, PFOS, Arsenic
Other certifiers’ wording: Total PFAS Reduction; Perfluorooctanoic Acid (PFOA); Perfluorooctane Sulfonate (PFOS); Arsenic (III) (50 ppb influent level)
- NSF/ANSI 58
Claims: Perfluorooctanoic Acid (PFOA), Perfluorooctane Sulfonate (PFOS), Uranium, Arsenic (Pentavalent)<=50 ppb Reduction
For: PFOA, PFOS, Uranium, Arsenic
Other certifiers’ wording: Arsenic (Pentavalent)<=300 ppb Reduction; Arsenic (V) (300 ppb influent level)
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. Uranium, arsenic, 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. Plumstead Twp Summer Hill Mead’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 Feb. 24, 2020 to Sept. 24, 2026; Pennsylvania’s PFAS results run from Feb. 22, 2024 to July 30, 2026.
