The short answer

2 results are above EPA’s legal limit, 2 more are above EPA’s new limit, which takes effect in 2029, and 1 more is above the health goal. The worst: Copper, above the action level. 3 health-based violations since 2016.

What was found

PFAS: Pennsylvania’s own results under its PFAS rule, entry point samples taken from Feb. 19, 2025 to July 15, 2026.

Lead and copper: EPA SDWIS monitoring periods ending 2004 to 2025.

Nitrate, total trihalomethanes (TTHM), arsenic, chromium (total), fluoride, haloacetic acids (HAA5) and uranium: Pennsylvania’s own results, samples taken from Jan. 9, 2020 to Aug. 27, 2026, with EPA’s 2012 to 2019 file for earlier years.

PFAS: PFOA, PFOS, 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.

Above the legal limit2

Copper

Comes from pipes, often your own

Above the action level

2.5ppm

90th percentile, 2025

In the latest period, 9 in 10 homes sampled were at or below 2.5 ppm, above EPA’s action level of 1.3 ppm.

What handles it

Nitrate

Comes from the source

Above the legal limit

16.2ppm

Highest sample; found in 29 of 29

2026 average: 6.3 ppm

In 2020, three samples were above EPA’s legal limit of 10 ppm, the highest 16.2 ppm. The next sample at the same point, within 30 days, kept the average above the limit for two; one has no follow-up sample on file within 30 days. In 2026, the latest year on file, its three samples averaged 6.3 ppm. EPA recorded a violation for nitrate at this utility in 2020. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 25.2 ppm, in 2019, and EPA recorded a violation in 2018.

8.7ppt

Highest sample, Aug. 20, 2025; found in 7 of 7

2026 average: 7.0 ppt

The highest sample was 8.7 ppt, about twice 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 7.4 ppt, for the year to Dec. 31, 2025: below Pennsylvania’s limit of 14 ppt and above EPA’s new limit of 4.0 ppt. In 2026, the latest year on file, its three samples averaged 7.0 ppt.

The highest sample was 4.2 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 3.8 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. Its only year on file is 2025, when its four samples averaged 3.8 ppt.

2025 average: 23.8 ppt

The highest sample was 33.2 ppt, below EPA’s hazard index benchmark of 2,000 ppt. PFBS has no legal limit or health goal of its own. Its only year on file is 2025, when its four samples averaged 23.8 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: Copper Reduction, Nitrate/Nitrite (30 ppm challenge), PFOA Reduction, PFOS Reduction, Lead Reduction

    For: Copper, Nitrate, PFOA, PFOS, Lead

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

  • NSF/ANSI 58

    Claims: Copper Reduction, Nitrate/Nitrite Reduction, Perfluorooctanoic Acid (PFOA), Perfluorooctane Sulfonate (PFOS), Lead Reduction

    Other certifiers’ wording: Nitrate

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

Very hard, 306 mg/L (17.9 grains per gallon), at its one sampling point, in 2026.

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, total trihalomethanes (TTHM), arsenic, chromium (total), fluoride, haloacetic acids (HAA5) and uranium results here are Pennsylvania’s own from 2020 on, with EPA’s national file for 2012 to 2019. Miller Manor Homeowners Assoc’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. 27, 2026; Pennsylvania’s PFAS results run from Feb. 19, 2025 to July 15, 2026.

Testing your own tap

Miller Manor Homeowners Assoc’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.

No lab Pennsylvania certifies is within 75 miles of the area Miller Manor Homeowners Assoc serves on the state’s list. Some take samples by mail; the state’s page lists them all.

Penn State Agricultural Analytical Services Laboratory: Drinking water test kits from many county Extension offices, mailed back to the lab overnight with payment. Packages cover bacteria and basic chemistry, with add-ons for nitrate, metals, lead, and mining or gas drilling concerns. The standard package of bacteria, pH and total dissolved solids is $60, or $70 with nitrate; bacteria alone is $40, nitrate $15 and lead $25.
