The short answer

1 result is above EPA’s new limit, which takes effect in 2029, and 3 more are above the health goal. The worst: PFOS, above EPA’s new limit (2029). 3 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 5, 2025 to May 12, 2026.

Lead and copper: EPA SDWIS monitoring periods ending 1994 to 1996.

Arsenic, nitrate, chromium (total), fluoride, haloacetic acids (HAA5), total trihalomethanes (TTHM) and uranium: Pennsylvania’s own results, samples taken from Sept. 24, 2020 to May 7, 2026, with EPA’s 2012 to 2019 file for earlier years.

PFAS: PFOS, PFOA and PFHxS were found, of the six PFAS in EPA’s 2024 drinking water rule; their results are below.

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.

PFOS

Above EPA’s new limit (2029)

5.0ppt

Highest sample, March 5, 2025; found in 5 of 5

2026 average: 4.6 ppt

The highest sample was 5.0 ppt, above EPA’s new limit of 4.0 ppt, which takes effect in 2029. EPA’s health goal is zero. Compliance will be judged on a running annual average, not one sample. Averaged over four quarters at one entry point, the way both Pennsylvania’s limit and EPA’s are judged, the highest was 4.6 ppt, for the year to June 30, 2026: below Pennsylvania’s limit of 18 ppt and above EPA’s new limit of 4.0 ppt. In 2026, the latest year on file, its two samples averaged 4.6 ppt.

2026 average: 3.3 ppt

The highest sample was 3.4 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 3.1 ppt, for the year to June 30, 2026: below Pennsylvania’s limit of 14 ppt and below EPA’s new limit of 4.0 ppt. In 2026, the latest year on file, its two samples averaged 3.3 ppt.

Lead

Comes from pipes, often your own

Above the health goal

2.5ppb

90th percentile, 1996

In the latest period, 9 in 10 homes sampled were at or below 2.5 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.

What handles it

Arsenic

Comes from the source

Above the health goal

1.0ppb

Highest yearly average, 2021

Averaged by year, the highest was 1.0 ppb, in 2021: below EPA’s legal limit of 10 ppb, but above its health goal of zero. That is the only year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 2.0 ppb, in 2012.

Highest sample; found in 7 of 7

2026, one sample: 2.2 ppm

The highest sample, in 2026, was 2.2 ppm, below EPA’s legal limit of 10 ppm. That was also the latest year on file, and its one sample was 2.2 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 3.9 ppm, in 2017.

What handles it

  • NSF/ANSI 58 look for “Nitrate/Nitrite Reduction”

2025 average: 1.4 ppt

The highest sample was 2.0 ppt, below EPA’s new limit of 10 ppt, which takes effect in 2029. No entry point has four quarters of results in a row to average, the way EPA’s limit is judged. Its only year on file is 2025, when its three samples averaged 1.4 ppt.

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, PFOA Reduction, Lead Reduction, Arsenic (Pentavalent)<=50 ppb Reduction

    For: PFOS, PFOA, Lead, Arsenic

    Other certifiers’ wording: Total PFAS Reduction; Perfluorooctane Sulfonate (PFOS); Perfluorooctanoic Acid (PFOA); Arsenic (III) (50 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, chromium (total), fluoride, haloacetic acids (HAA5), total trihalomethanes (TTHM) and uranium results here are Pennsylvania’s own from 2020 on, with EPA’s national file for 2012 to 2019. Country Crest MHP’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 Sept. 24, 2020 to May 7, 2026; Pennsylvania’s PFAS results run from March 5, 2025 to May 12, 2026.

Testing your own tap

Country Crest MHP’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.
