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. 1 health-based violation since 2016.

What handles it

What was found

PFAS: Pennsylvania’s own results under its PFAS rule, entry point samples taken from March 13, 2024 to Feb. 25, 2026.

Lead and copper: EPA SDWIS monitoring periods ending 1993 to 2019.

Copper: EPA’s file records a utility’s copper only when it exceeds the action level. The last here was 2.0 ppm, for the period ending Dec. 31, 1993. None since is on file, so it is not counted as a current finding.

Arsenic, total trihalomethanes (TTHM), haloacetic acids (HAA5), chromium (total), fluoride, nitrate and uranium: Pennsylvania’s own results, samples taken from Aug. 10, 2020 to Aug. 19, 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

24.5ppb

90th percentile, 2019

In the latest period, 9 in 10 homes sampled were at or below 24.5 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.

Arsenic

Above the health goal

2.0ppb

Highest yearly average, 2021 to 2024

2024, one sample: 1.8 ppb

Averaged by year, the highest was 2.0 ppb, in 2021: below EPA’s legal limit of 10 ppb, but above its health goal of zero. In 2024, the latest year on file, its one sample was 1.8 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 11.4 ppb, in 2017.

2026, one sample: 11.6 ppb

Averaged by year, the highest was 16 ppb, in 2025, below EPA’s legal limit of 80 ppb. In 2026, the latest year on file, its one sample was 11.6 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 12.3 ppb, in 2018.

2026: not found

Averaged by year, the highest was 3.0 ppb, in 2025, below EPA’s legal limit of 60 ppb. Its highest single sample was 3.7 ppb. In 2026, the latest year on file, it wasn’t found in its one sample. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 3.9 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.”

  • NSF/ANSI 53

    Claims: Lead Reduction, Arsenic (Pentavalent)<=50 ppb Reduction

    For: Lead, Arsenic

    Other certifiers’ wording: Arsenic (III) (50 ppb influent level)

  • NSF/ANSI 58

    Claims: Lead Reduction, Arsenic (Pentavalent)<=50 ppb Reduction

    For: Lead, Arsenic

    Other certifiers’ wording: Arsenic (Pentavalent)<=300 ppb Reduction; Arsenic (V) (300 ppb influent level)

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. Arsenic, total trihalomethanes (TTHM), haloacetic acids (HAA5), chromium (total), fluoride, nitrate and uranium results here are Pennsylvania’s own from 2020 on, with EPA’s national file for 2012 to 2019. Roulette Twp Water Authority’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 Aug. 10, 2020 to Aug. 19, 2026; Pennsylvania’s PFAS results run from March 13, 2024 to Feb. 25, 2026.

Testing your own tap

Roulette Twp Water Authority’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.
