The short answer

1 result is above EPA’s legal limit, and 1 more is above the health goal. The worst: Lead, above the action level. No health-based violations on file since 2016.

What handles it

What was found

PFAS: Pennsylvania’s own results under its PFAS rule, entry point samples taken from March 10, 2025 to Nov. 10, 2025.

Lead and copper: EPA SDWIS monitoring periods ending 1993.

Copper: EPA’s file records a utility’s copper only when it exceeds the action level. The last here was 4.1 ppm, for the period ending Dec. 31, 1993. None since is on file, so it is not counted as a current finding.

Nitrate, total trihalomethanes (TTHM), arsenic, chromium (total), fluoride, haloacetic acids (HAA5) and uranium: Pennsylvania’s own results, samples taken from Sept. 8, 2020 to Oct. 8, 2025, with EPA’s 2012 to 2019 file for earlier years.

PFAS: PFOS was found, of the six PFAS in EPA’s 2024 drinking water rule; its result is 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

Above the action level

20.9ppb

90th percentile, 1993

In the latest period, 9 in 10 homes sampled were at or below 20.9 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.

PFOS

Above the health goal

1.6ppt

Highest sample, Nov. 10, 2025; found in 1 of 4

2025 average: 0.41 ppt

The highest sample was 1.6 ppt: below EPA’s new limit of 4.0 ppt, which takes effect in 2029, but above its health goal of zero. Averaged over four quarters at one entry point, the way both Pennsylvania’s limit and EPA’s are judged, the highest was 0.41 ppt, for the year to Dec. 31, 2025: below Pennsylvania’s limit of 18 ppt and below EPA’s new limit of 4.0 ppt. Its only year on file is 2025, when its four samples averaged 0.41 ppt.

0.76ppm

Highest sample; found in 1 of 6

2025: not found

The highest sample, in 2024, was 0.76 ppm, below EPA’s legal limit of 10 ppm. In 2025, the latest year on file, it wasn’t found in its one sample. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 1.3 ppm, in 2015.

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, PFOS Reduction

    For: Lead, PFOS

    Other certifiers’ wording: Total PFAS Reduction; Perfluorooctane Sulfonate (PFOS)

  • NSF/ANSI 58

    Claims: Lead Reduction, Perfluorooctane Sulfonate (PFOS)

    For: Lead, PFOS

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. Nitrate, total trihalomethanes (TTHM), arsenic, chromium (total), fluoride, haloacetic acids (HAA5) and uranium results here are Pennsylvania’s own from 2020 on, with EPA’s national file for 2012 to 2019. Westwood Park Water Co’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 Sept. 8, 2020 to Oct. 8, 2025; Pennsylvania’s PFAS results run from March 10, 2025 to Nov. 10, 2025.

Testing your own tap

Westwood Park Water Co’s results are for the water it sends out. What your own service line, solder and fixtures add shows up only in a test of your tap, by a lab Pennsylvania certifies.
