The short answer

2 results are above EPA’s legal limit. The worst: Lead, above the action level. 15 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 Feb. 26, 2025 to Nov. 17, 2025.

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 4.4 ppm, for the period ending Dec. 31, 1998. None since is on file, so it is not counted as a current finding.

Haloacetic acids (HAA5), total trihalomethanes (TTHM), arsenic, chromium (total), fluoride and nitrate: Pennsylvania’s own results, samples taken from Feb. 24, 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, 2013 to Oct. 18, 2019. 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.

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

54.5ppb

90th percentile, 2019

In the latest period, 9 in 10 homes sampled were at or below 54.5 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.

What handles it

Haloacetic acids (HAA5)

Forms or is added in treatment

Above the legal limit

80.1ppb

Highest yearly average, 2020 to 2026

2026 average: 50.1 ppb

Averaged by year, the highest was 80.1 ppb, in 2022, above EPA’s legal limit of 60 ppb. Its highest single sample was 147 ppb. In 2026, the latest year on file, its four samples averaged 50.1 ppb. EPA recorded violations for haloacetic acids (HAA5) at this utility in 2020, 2021, 2022 and 2023. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 135 ppb, in 2016, and EPA recorded violations in 2016 and 2017.

Total trihalomethanes (TTHM)

Below EPA’s limits

71.2ppb

Highest yearly average, 2020 to 2026

2026 average: 58.2 ppb

Averaged by year, the highest was 71.2 ppb, in 2020, below EPA’s legal limit of 80 ppb. Its highest single sample was 113 ppb. In 2026, the latest year on file, its four samples averaged 58.2 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 77.3 ppb, in 2019.

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), arsenic, chromium (total), fluoride and nitrate 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. Icmsa Arcadia’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. 24, 2020 to Aug. 18, 2026; EPA’s compliance samples are from Dec. 13, 2013 to Oct. 18, 2019; Pennsylvania’s PFAS results run from Feb. 26, 2025 to Nov. 17, 2025.

Testing your own tap

Icmsa Arcadia’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.
