The ZIP code it serves
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: PFOS, above EPA’s new limit (2029). 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 March 3, 2025 to Aug. 3, 2026.
Lead and copper: EPA SDWIS monitoring periods ending 1993 to 1996.
Copper: EPA’s file records a utility’s copper only when it exceeds the action level. The last here was 8.2 ppm, for the period ending Dec. 31, 1993. 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. 6, 2020 to Aug. 3, 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.

| 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
PFOS
Comes from the source
10.5ppt
Highest sample, April 1, 2025; found in 7 of 7
2026 average: 8.9 ppt
The highest sample was 10.5 ppt, about 2.6 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 9.1 ppt, for the year to Dec. 31, 2025: below Pennsylvania’s limit of 18 ppt and above EPA’s new limit of 4.0 ppt. In 2026, the latest year on file, its three samples averaged 8.9 ppt.

PFOA
Comes from the source
8.2ppt
Highest sample, April 1, 2025; found in 7 of 7
2026 average: 7.9 ppt
The highest sample was 8.2 ppt, about twice 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 7.8 ppt, for the year to Sept. 30, 2026: 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 7.9 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, Lead Reduction
For: PFOS, PFOA, Lead
Other certifiers’ wording: Total PFAS Reduction; Perfluorooctane Sulfonate (PFOS); Perfluorooctanoic Acid (PFOA)
- NSF/ANSI 58
Claims: Perfluorooctane Sulfonate (PFOS), Perfluorooctanoic Acid (PFOA), Lead Reduction, Uranium
For: PFOS, PFOA, Lead, 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.

Hardness
Hard, 176 mg/L (10.3 grains per gallon), at its one sampling point, 2023 to 2024.
Hardness is calcium and magnesium. EPA sets no limit for it: it shows up as scale on fixtures and in water heaters, and as soap that won’t lather. USGS calls water above 60 mg/L moderately hard, above 120 hard and above 180 very hard.
Violations since 2016
No health-based violations on file with EPA since 2016. There are 2 monitoring or reporting violations: a sample missed, late or not reported.
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. Lca Upper Milford Central Div’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. 6, 2020 to Aug. 3, 2026; Pennsylvania’s PFAS results run from March 3, 2025 to Aug. 3, 2026.
