The short answer

1 result is above the limit’s level with no violation recorded, and 3 more are above EPA’s new limit, which takes effect in 2029. The worst: PFOS, above the limit’s level, no violation. No health-based violations on file since 2016.

What handles it

What was found

PFAS: Pennsylvania’s own results under its PFAS rule, entry point samples taken from Feb. 6, 2024 to Aug. 31, 2026.

Total trihalomethanes (TTHM) and haloacetic acids (HAA5): Pennsylvania’s own results, samples taken from Aug. 10, 2020 to Aug. 12, 2026, with EPA’s 2012 to 2019 file for earlier years.

PFAS: PFOS, PFNA, 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.

Above the limit’s level, no violation recorded1

226ppt

Highest sample, May 14, 2024; found in 92 of 92

2026 average: 24.4 ppt

The highest sample was 226 ppt, about 57 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 62.1 ppt, for the year to Dec. 31, 2024: above Pennsylvania’s limit of 18 ppt and above EPA’s new limit of 4.0 ppt. Pennsylvania recorded no violation of its limit for PFOS here; its own reckoning of the average, which decides compliance, may count quarters or samples differently. In 2026, the latest year on file, its 26 samples averaged 24.4 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, Total PFAS Reduction, PFOA Reduction

    For: PFOS, PFNA, PFOA, PFHxS

    Other certifiers’ wording: Perfluorooctane Sulfonate (PFOS); Perfluorononanoic Acid (PFNA); Perfluorooctanoic Acid (PFOA); Perfluorohexane Sulfonic Acid (PFHxS)

  • NSF/ANSI 58

    Claims: Perfluorooctane Sulfonate (PFOS), Perfluorooctanoic Acid (PFOA)

    For: PFOS, PFOA

At the tap, or for the whole house?

These come with the water itself, so a whole-house system certified for the same claims treats every tap and shower. A filter at the tap treats drinking water for much less. How whole-house systems compare.

Hardness

Very hard, 183 mg/L (10.7 grains per gallon), at its one sampling point, in 2025.

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. Total trihalomethanes (TTHM) and haloacetic acids (HAA5) results here are Pennsylvania’s own from 2020 on, with EPA’s national file for 2012 to 2019. Lca Emmaus Consecutive Div’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. 10, 2020 to Aug. 12, 2026; Pennsylvania’s PFAS results run from Feb. 6, 2024 to Aug. 31, 2026.

Testing your own tap

Lca Emmaus Consecutive Div’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.
