The short answer

2 results are above EPA’s legal limit. The worst: Lead, above the action level. 18 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 March 20, 2025 to Dec. 1, 2025.

Lead and copper: EPA SDWIS monitoring periods ending 1993 to 2025.

Haloacetic acids (HAA5), total trihalomethanes (TTHM), nitrate, arsenic, chromium (total) and fluoride: Pennsylvania’s own results, samples taken from Feb. 13, 2020 to Aug. 18, 2026, with EPA’s 2012 to 2019 file for earlier years.

Uranium: EPA’s compliance monitoring file, samples taken from Dec. 13, 2017 to Dec. 13, 2017. Newer results are in the utility’s annual water quality report.

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 limit2

Lead

Comes from pipes, often your own

Above the action level

23.7ppb

90th percentile, 2025

In the latest period, 9 in 10 homes sampled were at or below 23.7 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.

Above the legal limit

73.1ppb

Highest yearly average, 2020 to 2026

2026 average: 41.5 ppb

Averaged by year, the highest was 73.1 ppb, in 2020, above EPA’s legal limit of 60 ppb. Its highest single sample was 101 ppb. In 2026, the latest year on file, its eight samples averaged 41.5 ppb. EPA recorded violations for haloacetic acids (HAA5) at this utility in 2020, 2021, 2022, 2023 and 2024. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 51.7 ppb, in 2018.

Highest yearly average, 2020 to 2026

2026 average: 35.6 ppb

Averaged by year, the highest was 53.8 ppb, in 2020, below EPA’s legal limit of 80 ppb. Its highest single sample was 77.9 ppb. In 2026, the latest year on file, its eight samples averaged 35.6 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 75.5 ppb, in 2015, and EPA recorded a violation in 2019.

Highest sample; found in 1 of 6

2025, one sample: 1.2 ppm

The highest sample, in 2025, was 1.2 ppm, below EPA’s legal limit of 10 ppm. That was also the latest year on file, and its one sample was 1.2 ppm.

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. Haloacetic acids (HAA5), total trihalomethanes (TTHM), nitrate, arsenic, chromium (total) and fluoride results here are Pennsylvania’s own from 2020 on, with EPA’s national file for 2012 to 2019. Uranium comes from EPA’s file alone, which ends in 2019. Centerville Muni Water Auth’s own annual report, which it must send you every year, has newer results for those and 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. 13, 2020 to Aug. 18, 2026; EPA’s compliance samples are from Dec. 13, 2017 to Dec. 13, 2017; Pennsylvania’s PFAS results run from March 20, 2025 to Dec. 1, 2025.

Testing your own tap

Centerville Muni Water Auth’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.
