The short answer
1 result is above EPA’s legal limit, 2 more are above EPA’s new limit, which takes effect in 2029, and 1 more is above the health goal. The worst: Lead, above the action level. 9 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 17, 2025 to Sept. 10, 2026.
Lead and copper: EPA SDWIS monitoring periods ending 1996 to 2013.
Copper: EPA’s file records a utility’s copper only when it exceeds the action level. The last here was 3.3 ppm, for the period ending Dec. 31, 2000. None since is on file, so it is not counted as a current finding.
Uranium, nitrate, total trihalomethanes (TTHM), haloacetic acids (HAA5), arsenic, chromium (total) and fluoride: Pennsylvania’s own results, samples taken from Jan. 8, 2020 to Aug. 21, 2026, with EPA’s 2012 to 2019 file for earlier years.
PFAS: PFOA, PFOS, 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 12 ppt: see them 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.
Above the legal limit1
Lead
Comes from pipes, often your own
271ppb
90th percentile, 2013
In the latest period, 9 in 10 homes sampled were at or below 271 ppb, above EPA’s action level of 15 ppb. The action level drops to 10 ppb on Nov. 1, 2027, and this result is at or above that. EPA’s health goal for lead is zero.

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: Lead Reduction, PFOA Reduction, PFOS Reduction
For: Lead, PFOA, PFOS
Other certifiers’ wording: Total PFAS Reduction; Perfluorooctanoic Acid (PFOA); Perfluorooctane Sulfonate (PFOS)
- NSF/ANSI 58
Claims: Lead Reduction, Perfluorooctanoic Acid (PFOA), Perfluorooctane Sulfonate (PFOS), Uranium
For: Lead, PFOA, PFOS, Uranium
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. Uranium, nitrate, total trihalomethanes (TTHM), haloacetic acids (HAA5), arsenic, chromium (total) and fluoride results here are Pennsylvania’s own from 2020 on, with EPA’s national file for 2012 to 2019. Brinton Manor’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 Jan. 8, 2020 to Aug. 21, 2026; Pennsylvania’s PFAS results run from March 17, 2025 to Sept. 10, 2026.
