The short answer

1 result is above EPA’s legal limit, and 1 more is above the health goal. The worst: Haloacetic acids (HAA5), above the legal limit. 8 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 Jan. 17, 2024 to June 12, 2026.

Lead and copper: EPA SDWIS monitoring periods ending 1993 to 1996.

Haloacetic acids (HAA5), total trihalomethanes (TTHM), nitrate, arsenic, chromium (total), fluoride and uranium: Pennsylvania’s own results, samples taken from Jan. 3, 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.

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

Haloacetic acids (HAA5)

Forms or is added in treatment

Above the legal limit

68.7ppb

Highest yearly average, 2020 to 2026

2026 average: 43.2 ppb

Averaged by year, the highest was 68.7 ppb, in 2025, above EPA’s legal limit of 60 ppb. Its highest single sample was 91.7 ppb. In 2026, the latest year on file, its six samples averaged 43.2 ppb. EPA recorded violations for haloacetic acids (HAA5) at this utility in 2022, 2023 and 2025. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 46.2 ppb, in 2013.

Above the health goal

1.0ppb

90th percentile, 1996

In the latest period, 9 in 10 homes sampled were at or below 1.0 ppb, below EPA’s action level of 15 ppb. The action level drops to 10 ppb on Nov. 1, 2027. EPA’s health goal for lead is zero.

Below EPA’s limits

74.3ppb

Highest yearly average, 2020 to 2026

2026 average: 52.3 ppb

Averaged by year, the highest was 74.3 ppb, in 2025, below EPA’s legal limit of 80 ppb. Its highest single sample was 99 ppb. In 2026, the latest year on file, its six samples averaged 52.3 ppb. EPA recorded no violation for total trihalomethanes (TTHM) at this utility since 2020. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 78.6 ppb, in 2015, and EPA recorded a violation in 2016.

2026, one sample: 1.3 ppm

The highest sample, in 2026, was 1.3 ppm, below EPA’s legal limit of 10 ppm. That was also the latest year on file, and its one sample was 1.3 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 1.3 ppm, in 2017.

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), fluoride and uranium results here are Pennsylvania’s own from 2020 on, with EPA’s national file for 2012 to 2019. Reynolds Water Company’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 Jan. 3, 2020 to Aug. 13, 2026; Pennsylvania’s PFAS results run from Jan. 17, 2024 to June 12, 2026.

Testing your own tap

Reynolds Water Company’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.
