What this report can’t tell you

  • Everything else. Total trihalomethanes (TTHM) and haloacetic acids (HAA5) results here are Pennsylvania’s own from 2021 on, with EPA’s national file for 2012 to 2019. South Park Mhc LLC’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 Nov. 11, 2021 to Aug. 13, 2026.

Testing your own tap

South Park Mhc LLC’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 South Park Mhc LLC serves on the state’s list. Some take samples by mail; the state’s page lists them all.
