The short answer
1 result is above EPA’s legal limit. The worst: Total trihalomethanes (TTHM), above the legal limit. 5 health-based violations since 2016.
What handles itWhat was found
PFAS: Pennsylvania’s own results under its PFAS rule, entry point samples taken from Nov. 21, 2024 to June 23, 2025.
Total trihalomethanes (TTHM) and haloacetic acids (HAA5): Pennsylvania’s own results, samples taken from Feb. 4, 2020 to July 31, 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 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
Claim: Trihalomethanes (TTHM) Reduction
For: Total trihalomethanes (TTHM)
Other certifiers’ wording: VOC Reduction
- NSF/ANSI 58
Claim: Trihalomethanes (TTHM) Reduction
For: Total trihalomethanes (TTHM)
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.

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. Landis Homes’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 Feb. 4, 2020 to July 31, 2026; Pennsylvania’s PFAS results run from Nov. 21, 2024 to June 23, 2025.
