The short answer

3 results are above the health goal. The worst: PFOS, above the health goal. 2 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 31, 2025 to June 5, 2026.

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

Copper: EPA’s file records a utility’s copper only when it exceeds the action level. The last here was 1.4 ppm, for the period ending Dec. 31, 2010. None since is on file, so it is not counted as a current finding.

Arsenic, nitrate, total trihalomethanes (TTHM), haloacetic acids (HAA5), chromium (total), fluoride and uranium: Pennsylvania’s own results, samples taken from Jan. 9, 2020 to Aug. 12, 2026, with EPA’s 2012 to 2019 file for earlier years.

PFAS: PFOS was found, of the six PFAS in EPA’s 2024 drinking water rule; its result is below. None of the other 12 PFAS tested for was found.

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.

About PFAS certifications

NSF’s PFAS claims are tested to below 20 ppt. EPA’s limit is 4.0 ppt, and EPA says no certification yet shows a filter reaching its levels.

Above the health goal3

PFOS

Comes from the source

Above the health goal

2.0ppt

Highest sample, Nov. 19, 2025; found in 2 of 12

2026: not found

The highest sample was 2.0 ppt: below EPA’s new limit of 4.0 ppt, which takes effect in 2029, but above its health goal of zero. Averaged over four quarters at one entry point, the way both Pennsylvania’s limit and EPA’s are judged, the highest was 0.5 ppt, for the year to Dec. 31, 2025: below Pennsylvania’s limit of 18 ppt and below EPA’s new limit of 4.0 ppt. In 2026, the latest year on file, it wasn’t found in any of its four samples.

What handles it

Arsenic

Comes from the source

Above the health goal

3.0ppb

Highest yearly average, 2021 to 2025

Averaged by year, the highest was 3.0 ppb, in 2025: below EPA’s legal limit of 10 ppb, but above its health goal of zero. Its highest single sample was 3.2 ppb. That was also the latest year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 4.5 ppb, in 2012.

What handles it

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

Lead

Comes from pipes, often your own

Above the health goal

2.0ppb

90th percentile, 1996

In the latest period, 9 in 10 homes sampled were at or below 2.0 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 limits3

Nitrate

Comes from the source

Below EPA’s limits

5.5ppm

Highest sample; found in 27 of 27

2026 average: 3.2 ppm

The highest sample, in 2023, was 5.5 ppm, below EPA’s legal limit of 10 ppm. In 2026, the latest year on file, its three samples averaged 3.2 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 8.0 ppm, in 2018.

Below EPA’s limits

5.2ppb

Highest yearly average, 2021 to 2026

Averaged by year, the highest was 5.2 ppb, in 2026, below EPA’s legal limit of 80 ppb. Its highest single sample was 6.7 ppb. That was also the latest year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 1.9 ppb, in 2012.

Below EPA’s limits

2.0ppb

Highest yearly average, 2021 to 2026

Averaged by year, the highest was 2.0 ppb, in 2026, below EPA’s legal limit of 60 ppb. Its highest single sample was 3.9 ppb. That was also the latest year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 1.9 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

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

    For: PFOS, Arsenic, Lead

    Other certifiers’ wording: Total PFAS Reduction; Perfluorooctane Sulfonate (PFOS); Arsenic (III) (50 ppb influent level)

  • NSF/ANSI 58

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

    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, nitrate, total trihalomethanes (TTHM), haloacetic acids (HAA5), chromium (total), fluoride and uranium results here are Pennsylvania’s own from 2020 on, with EPA’s national file for 2012 to 2019. Halifax Village’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. 9, 2020 to Aug. 12, 2026; Pennsylvania’s PFAS results run from March 31, 2025 to June 5, 2026.

Testing your own tap

Halifax Village’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.
