The short answer

1 result is above EPA’s legal limit. The worst: Lead, above the action level. 2 health-based violations since 2016.

What handles it

What was found

PFAS: Pennsylvania’s own results under its PFAS rule, entry point samples taken from June 12, 2024 to June 9, 2026.

Lead and copper: EPA SDWIS monitoring periods ending 1994 to 2003.

Nitrate, total trihalomethanes (TTHM), haloacetic acids (HAA5), arsenic, chromium (total), fluoride and uranium: Pennsylvania’s own results, samples taken from Feb. 12, 2020 to Aug. 13, 2026, with EPA’s 2012 to 2019 file for earlier years.

PFAS: None of the six PFAS in EPA’s 2024 drinking water rule was found in this utility’s samples. None of the other 12 PFAS tested for was found either.

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.

Above the legal limit1

Lead

Comes from pipes, often your own

Above the action level

20ppb

90th percentile, 2003

In the latest period, 9 in 10 homes sampled were at or below 20 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.

Below EPA’s limits3

Nitrate

Below EPA’s limits

8.9ppm

Highest sample; found in 26 of 26

2026 average: 7.5 ppm

The highest sample, in 2024, was 8.9 ppm, below EPA’s legal limit of 10 ppm. In 2026, the latest year on file, its three samples averaged 7.5 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 6.9 ppm, in 2019.

Below EPA’s limits

16.6ppb

Highest yearly average, 2020 to 2026

2026 average: 7.6 ppb

Averaged by year, the highest was 16.6 ppb, in 2022, below EPA’s legal limit of 80 ppb. Its highest single sample was 27.8 ppb. In 2026, the latest year on file, its three samples averaged 7.6 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 10 ppb, in 2013.

10.8ppb

Highest yearly average, 2020 to 2026

2026 average: 4.2 ppb

Averaged by year, the highest was 10.8 ppb, in 2022, below EPA’s legal limit of 60 ppb. Its highest single sample was 14.5 ppb. In 2026, the latest year on file, its three samples averaged 4.2 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 2.8 ppb, in 2016.

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.”

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), haloacetic acids (HAA5), arsenic, chromium (total), fluoride and uranium results here are Pennsylvania’s own from 2020 on, with EPA’s national file for 2012 to 2019. Selinsgrove Center’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. 12, 2020 to Aug. 13, 2026; Pennsylvania’s PFAS results run from June 12, 2024 to June 9, 2026.

Testing your own tap

Selinsgrove Center’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.
