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. 2 health-based violations since 2016.

What was found

PFAS: Pennsylvania’s own results under its PFAS rule, entry point samples taken from Jan. 22, 2025 to Nov. 12, 2025.

Fluoride, arsenic, chromium (total), haloacetic acids (HAA5), nitrate, total trihalomethanes (TTHM) and uranium: Pennsylvania’s own results, samples taken from July 14, 2020 to July 21, 2026, with EPA’s 2012 to 2019 file for earlier years.

PFAS: None of the six 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.

What this report can’t tell you

  • Everything else. Fluoride, arsenic, chromium (total), haloacetic acids (HAA5), nitrate, total trihalomethanes (TTHM) and uranium results here are Pennsylvania’s own from 2020 on, with EPA’s national file for 2012 to 2019. Hemlock Village MHP’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 July 14, 2020 to July 21, 2026; Pennsylvania’s PFAS results run from Jan. 22, 2025 to Nov. 12, 2025.

Testing your own tap

Hemlock Village MHP’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.
