The short answer

Nothing in EPA’s and Pennsylvania’s records for this utility is above a health goal. That covers PFAS; nitrate, arsenic and other regulated chemicals; and lead and copper, 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 19, 2024 to May 28, 2026.

Copper: EPA’s file records a utility’s copper only when it exceeds the action level. The last here was 1.5 ppm, for the period ending Dec. 31, 2015. None since is on file, so it is not counted as a current finding.

Total trihalomethanes (TTHM), haloacetic acids (HAA5), arsenic, chromium (total), fluoride, nitrate and uranium: Pennsylvania’s own results, samples taken from Aug. 25, 2020 to Aug. 13, 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.

EPA’s 2024 PFAS rule, compound by compound

PFAS	EPA’s limit	Result
PFOA	4.0 ppt	Not foundNot found in any of 5 samples
PFOS	4.0 ppt	Not foundNot found in any of 5 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. 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. Mill Creek Area Mun Auth’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. 25, 2020 to Aug. 13, 2026; Pennsylvania’s PFAS results run from March 19, 2024 to May 28, 2026.

Testing your own tap

Mill Creek Area Mun Auth’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.
