The short answer

1 result is above the health goal. The worst: Arsenic, above the health goal. 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 10, 2025 to Dec. 16, 2025.

Arsenic, fluoride, nitrate, total trihalomethanes (TTHM), chromium (total), haloacetic acids (HAA5) and uranium: Pennsylvania’s own results, samples taken from Aug. 13, 2020 to July 29, 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.

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 health goal1

Arsenic

Comes from the source

Above the health goal

2.0ppb

Highest yearly average, 2021 to 2024

2024 average: 0.5 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 two samples averaged 0.5 ppb.

What handles it

  • NSF/ANSI 58 look for “Arsenic (Pentavalent)<=50 ppb Reduction”
  • NSF/ANSI 53 look for “Arsenic (Pentavalent)<=50 ppb Reduction”

Below EPA’s limits3

Fluoride

Forms or is added in treatment

Below EPA’s limits

0.33ppm

Highest yearly average, 2021 to 2024

2024 average: 0.24 ppm

Averaged by year, the highest was 0.33 ppm, in 2021, below EPA’s legal limit of 4.0 ppm. In 2024, the latest year on file, its two samples averaged 0.24 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 0.35 ppm, in 2012.

What handles it

Nitrate

Comes from the source

Below EPA’s limits

0.21ppm

Highest sample; found in 2 of 7

2026: not found

The highest sample, in 2022, was 0.21 ppm, below EPA’s legal limit of 10 ppm. 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 sample of 0.04 ppm, in 2012.

What handles it

  • NSF/ANSI 58 look for “Nitrate/Nitrite Reduction”
  • NSF/ANSI 53 look for “Nitrate/Nitrite (30 ppm challenge)”

Total trihalomethanes (TTHM)

Forms or is added in treatment

Below EPA’s limits

1.1ppb

Highest yearly average, 2022 to 2025

2025: not found

Averaged by year, the highest was 1.1 ppb, in 2022, below EPA’s legal limit of 80 ppb. 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 yearly average of 5.5 ppb, in 2012.

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

    Claim: Arsenic (Pentavalent)<=50 ppb Reduction

    For: Arsenic

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

  • NSF/ANSI 58

    Claim: Arsenic (Pentavalent)<=50 ppb Reduction

    For: Arsenic

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

At the tap, or for the whole house?

These come with the water itself, so a whole-house system certified for the same claims treats every tap and shower. A filter at the tap treats drinking water for much less. How whole-house systems compare.

What this report can’t tell you

  • Everything else. Arsenic, fluoride, nitrate, total trihalomethanes (TTHM), chromium (total), haloacetic acids (HAA5) and uranium results here are Pennsylvania’s own from 2020 on, with EPA’s national file for 2012 to 2019. Corry Two Mhc’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. 13, 2020 to July 29, 2026; Pennsylvania’s PFAS results run from March 10, 2025 to Dec. 16, 2025.

Testing your own tap

Corry Two Mhc’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.
