The short answer

Nothing in EPA’s and Pennsylvania’s records for this utility is above a health goal. That covers PFAS, plus nitrate, arsenic and other regulated chemicals, not everything. No health-based violations on file since 2016.

What was found

PFAS: Pennsylvania’s own results under its PFAS rule, entry point samples taken from March 13, 2025 to Nov. 13, 2025.

Nitrate, total trihalomethanes (TTHM), haloacetic acids (HAA5), arsenic, chromium (total), fluoride and uranium: Pennsylvania’s own results, samples taken from Aug. 6, 2020 to Aug. 27, 2026, with EPA’s 2012 to 2019 file for earlier years.

PFAS: None of the two PFAS in EPA’s 2024 drinking water rule was found in this utility’s samples.

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.

Below EPA’s limits3

Nitrate

Comes from the source

Below EPA’s limits

0.59ppm

Highest sample; found in 3 of 7

2026: not found

The highest sample, in 2022, was 0.59 ppm, below EPA’s legal limit of 10 ppm. In 2026, the latest year on file, it wasn’t found in its one sample. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 0.48 ppm, in 2012.

What handles it

  • NSF/ANSI 58 look for “Nitrate/Nitrite Reduction”
  • NSF/ANSI 53 look for “Nitrate/Nitrite (30 ppm challenge)”

Total trihalomethanes (TTHM)

Forms or is added in treatment

Below EPA’s limits

3.9ppb

Highest yearly average, 2022 to 2025

Averaged by year, the highest was 3.9 ppb, in 2025, below EPA’s legal limit of 80 ppb. That was also the latest year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 1.0 ppb, in 2012.

What handles it

  • NSF/ANSI 53 look for “Trihalomethanes (TTHM) Reduction”
  • NSF/ANSI 58 look for “Trihalomethanes (TTHM) Reduction”

Haloacetic acids (HAA5)

Forms or is added in treatment

Below EPA’s limits

1.9ppb

Highest yearly average, 2022 to 2025

Averaged by year, the highest was 1.9 ppb, in 2025, below EPA’s legal limit of 60 ppb. That was also the latest year on file.

Violations since 2016

No health-based violations on file with EPA since 2016. There are 45 monitoring or reporting violations: a sample missed, late or not reported.

What this report can’t tell you

  • Everything else. Nitrate, total trihalomethanes (TTHM), haloacetic acids (HAA5), arsenic, chromium (total), fluoride and uranium results here are Pennsylvania’s own from 2020 on, with EPA’s national file for 2012 to 2019. Ludlow County Line System’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. 27, 2026; Pennsylvania’s PFAS results run from March 13, 2025 to Nov. 13, 2025.

Testing your own tap

Ludlow County Line System’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 Ludlow County Line System 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.
