The short answer

4 results are above EPA’s legal limit, and 1 more is above the health goal. The worst: PFOS, above Pennsylvania’s limit. 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 17, 2023 to July 10, 2026.

Lead and copper: EPA SDWIS monitoring periods ending 1993 to 2022.

Nitrate, arsenic, chromium (total), fluoride, haloacetic acids (HAA5) and total trihalomethanes (TTHM): Pennsylvania’s own results, samples taken from Feb. 24, 2020 to April 17, 2026, with EPA’s 2012 to 2019 file for earlier years.

Uranium: EPA’s compliance monitoring file, samples taken from Oct. 18, 2013 to May 13, 2019. Newer results are in the utility’s annual water quality report.

PFAS: PFOS, PFOA, PFHxS and PFBS 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 Pennsylvania’s limit

56ppt

Highest sample, April 5, 2024; found in 15 of 15

2026 average: 41.8 ppt

The highest sample was 56 ppt, about 14 times 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 53.8 ppt, for the year to Sept. 30, 2024: above Pennsylvania’s limit of 18 ppt and above EPA’s new limit of 4.0 ppt. Pennsylvania recorded 11 violations of its limit for PFOS here, dated Aug. 9, 2023, Oct. 19, 2023, Jan. 30, 2024 and 8 more dates, on running averages of 22 to 54 ppt. In 2026, the latest year on file, its three samples averaged 41.8 ppt.

Pennsylvania recorded 10 violations of its limit for PFOA here, dated Aug. 9, 2023, Oct. 19, 2023, Jan. 30, 2024 and 7 more dates, on running averages of 19 to 39 ppt. In 2026, the latest year on file, its three samples averaged 26 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, Copper Reduction, Lead Reduction

    For: PFOS, PFOA, Copper, Lead

    Other certifiers’ wording: Total PFAS Reduction; Perfluorooctane Sulfonate (PFOS); Perfluorooctanoic Acid (PFOA)

  • NSF/ANSI 58

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.

Hardness

Soft, 8.2 mg/L (0.5 grains per gallon), at its one sampling point, in 2021.

Hardness is calcium and magnesium. EPA sets no limit for it: it shows up as scale on fixtures and in water heaters, and as soap that won’t lather. USGS calls water above 60 mg/L moderately hard, above 120 hard and above 180 very hard.

What this report can’t tell you

  • Everything else. Nitrate, arsenic, chromium (total), fluoride, haloacetic acids (HAA5) and total trihalomethanes (TTHM) 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. Perry Phillips Mobile Homes’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 April 17, 2026; EPA’s compliance samples are from Oct. 18, 2013 to May 13, 2019; Pennsylvania’s PFAS results run from March 17, 2023 to July 10, 2026.

Testing your own tap

Perry Phillips Mobile Homes’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.
