The short answer

2 results are above the health goal. The worst: Lead, 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 Feb. 17, 2025 to Oct. 21, 2025.

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

Total trihalomethanes (TTHM), haloacetic acids (HAA5), arsenic, chromium (total), fluoride, nitrate and uranium: Pennsylvania’s own results, samples taken from Aug. 6, 2020 to Aug. 12, 2026, with EPA’s 2012 to 2019 file for earlier years.

PFAS: PFOA was found, of the six PFAS in EPA’s 2024 drinking water rule; its result is 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.

Above the health goal2

Lead

Comes from pipes, often your own

Above the health goal

11ppb

90th percentile, 1996

In the latest period, 9 in 10 homes sampled were at or below 11 ppb, below 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.

PFOA

Above the health goal

0.72ppt

Highest sample, May 14, 2025; found in 2 of 4

2025 average: 0.28 ppt

The highest sample was 0.72 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 0.28 ppt, for the year to Dec. 31, 2025: below Pennsylvania’s limit of 14 ppt and below EPA’s new limit of 4.0 ppt. Its only year on file is 2025, when its four samples averaged 0.28 ppt.

Highest yearly average, 2020 to 2026

2026 average: 25.9 ppb

Averaged by year, the highest was 70 ppb, in 2024, below EPA’s legal limit of 80 ppb. Its highest single sample was 97.3 ppb. In 2026, the latest year on file, its three samples averaged 25.9 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 56.5 ppb, in 2018.

Averaged by year, the highest was 22.8 ppb, in 2025, below EPA’s legal limit of 60 ppb. Its highest single sample was 50.8 ppb. In 2026, the latest year on file, its three samples averaged 20.8 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 24.9 ppb, in 2018.

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: Lead Reduction, PFOA Reduction

    For: Lead, PFOA

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

  • NSF/ANSI 58

    Claims: Lead Reduction, Perfluorooctanoic Acid (PFOA)

    For: Lead, PFOA

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. Total trihalomethanes (TTHM), haloacetic acids (HAA5), arsenic, chromium (total), fluoride, nitrate and uranium results here are Pennsylvania’s own from 2020 on, with EPA’s national file for 2012 to 2019. Mary D Community Association’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 Aug. 6, 2020 to Aug. 12, 2026; Pennsylvania’s PFAS results run from Feb. 17, 2025 to Oct. 21, 2025.

Testing your own tap

Mary D Community Association’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.
