The ZIP code it serves
The short answer
2 results are above EPA’s new limit, which takes effect in 2029, and 1 more is above the health goal. The worst: PFOS, above EPA’s new limit (2029). No health-based violations on file since 2016.
What handles itWhat was found
PFAS: Pennsylvania’s own results under its PFAS rule, entry point samples taken from Feb. 18, 2025 to Oct. 15, 2025.
Lead and copper: EPA SDWIS monitoring periods ending 1993 to 1996.
Nitrate, fluoride, total trihalomethanes (TTHM), haloacetic acids (HAA5), arsenic, chromium (total) and uranium: Pennsylvania’s own results, samples taken from March 18, 2020 to Aug. 19, 2026, with EPA’s 2012 to 2019 file for earlier years.
PFAS: PFOS, PFOA and PFBS were found, of the six PFAS in EPA’s 2024 drinking water rule; their results are below.

| 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. | ||
About PFAS certifications
NSF’s PFAS claims are tested to below 20 ppt. EPA’s limit is 4.0 ppt, and EPA says no certification yet shows a filter reaching its levels.
Above EPA’s new limit, which takes effect in 20292
PFOS
Comes from the source
4.7ppt
Highest sample, April 16, 2025; found in 2 of 4
2025 average: 2.3 ppt
The highest sample was 4.7 ppt, above EPA’s new limit of 4.0 ppt, which takes effect in 2029. EPA’s health goal is zero. Compliance will be judged on a running annual average, not one sample. Averaged over four quarters at one entry point, the way both Pennsylvania’s limit and EPA’s are judged, the highest was 2.3 ppt, for the year to Dec. 31, 2025: below Pennsylvania’s limit of 18 ppt and below EPA’s new limit of 4.0 ppt. Its only year on file is 2025, when its four samples averaged 2.3 ppt.

2025 average: 2.0 ppt
The highest sample was 4.2 ppt, above EPA’s new limit of 4.0 ppt, which takes effect in 2029. EPA’s health goal is zero. Compliance will be judged on a running annual average, not one sample. Averaged over four quarters at one entry point, the way both Pennsylvania’s limit and EPA’s are judged, the highest was 2.0 ppt, for the year to Dec. 31, 2025: below Pennsylvania’s limit of 14 ppt and below EPA’s new limit of 4.0 ppt. Its only year on file is 2025, when its four samples averaged 2.0 ppt.

Lead
Comes from pipes, often your own
9.0ppb
90th percentile, 1996
In the latest period, 9 in 10 homes sampled were at or below 9.0 ppb, below EPA’s action level of 15 ppb. The action level drops to 10 ppb on Nov. 1, 2027. EPA’s health goal for lead is zero.

Nitrate
Comes from the source
10.1ppm
Highest sample; found in 28 of 28
2026 average: 4.3 ppm
The highest sample, in 2025, was 10.1 ppm, which EPA rounds to 10 ppm to compare: at its legal limit of 10 ppm, not above it. In 2026, the latest year on file, its four samples averaged 4.3 ppm. EPA recorded no violation for nitrate at this utility since 2020. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 10.4 ppm, in 2018.

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
Claims: PFOS Reduction, PFOA Reduction, Lead Reduction
For: PFOS, PFOA, Lead
Other certifiers’ wording: Total PFAS Reduction; Perfluorooctane Sulfonate (PFOS); Perfluorooctanoic Acid (PFOA)
- NSF/ANSI 58
Claims: Perfluorooctane Sulfonate (PFOS), Perfluorooctanoic Acid (PFOA), Lead Reduction
For: PFOS, PFOA, Lead
At the tap, or for the whole house?
Lead and copper usually come from pipes and fixtures inside or near your home. A whole-house system sits where water enters, so it cannot catch what your own plumbing adds after it. For those, the filter that counts is the one at the tap. How whole-house systems compare.

What this report can’t tell you
Everything else. Nitrate, fluoride, total trihalomethanes (TTHM), haloacetic acids (HAA5), arsenic, chromium (total) and uranium results here are Pennsylvania’s own from 2020 on, with EPA’s national file for 2012 to 2019. Hideaway Mobile Home Park’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 March 18, 2020 to Aug. 19, 2026; Pennsylvania’s PFAS results run from Feb. 18, 2025 to Oct. 15, 2025.
