The short answer
2 results are above the health goal. The worst: Arsenic, above the health goal. 1 health-based violation since 2016.
What handles itWhat was found
PFAS: Pennsylvania’s own results under its PFAS rule, entry point samples taken from March 13, 2025 to Dec. 9, 2025.
Arsenic, uranium, nitrate, total trihalomethanes (TTHM), chromium (total), fluoride and haloacetic acids (HAA5): Pennsylvania’s own results, samples taken from March 5, 2020 to March 17, 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.
EPA’s 2024 PFAS rule, compound by compound
| PFAS | EPA’s limit | Result |
|---|---|---|
| PFOA | 4.0 ppt | Not foundNot found in any of 4 samples |
| PFOS | 4.0 ppt | Not foundNot found in any of 4 samples |
| PFHxS | 10 ppt | Not foundNot found in any of 4 samples |
| PFNA | 10 ppt | Not foundNot found in any of 4 samples |
| HFPO-DA (GenX) | 10 ppt | Not foundNot found in any of 4 samples |
| PFBS | Index only | Not foundNot found in any of 4 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. | ||
Above the health goal2
Arsenic
Comes from the source
4.0ppb
Highest yearly average, 2021 to 2024
2024, one sample: 2.4 ppb
Averaged by year, the highest was 4.0 ppb, in 2021: below EPA’s legal limit of 10 ppb, but above its health goal of zero. In 2024, the latest year on file, its one sample was 2.4 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 5.0 ppb, in 2012.

- NSF/ANSI 53 look for “Arsenic (Pentavalent)<=50 ppb Reduction”
Uranium
Comes from the source
5.8ppb
Highest yearly average, 2020 to 2025
Averaged by year, the highest was 5.8 ppb, in 2025: below EPA’s legal limit of 30 ppb, but above its health goal of zero. That was also the latest year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 6.5 ppb, in 2013.
What handles it
- NSF/ANSI 58 look for “Uranium”
Below EPA’s limits2
Nitrate
Comes from the source
0.78ppm
Highest sample; found in 6 of 7
2026, one sample: 0.69 ppm
The highest sample, in 2025, was 0.78 ppm, below EPA’s legal limit of 10 ppm. In 2026, the latest year on file, its one sample was 0.69 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 0.8 ppm, in 2014.

Total trihalomethanes (TTHM)
Forms or is added in treatment
5.8ppb
Highest yearly average, 2021 to 2024
2024, one sample: 5.4 ppb
Averaged by year, the highest was 5.8 ppb, in 2021, below EPA’s legal limit of 80 ppb. In 2024, the latest year on file, its one sample was 5.4 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 4.6 ppb, in 2014.

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: Arsenic (Pentavalent)<=50 ppb Reduction
For: Arsenic
Other certifiers’ wording: Arsenic (III) (50 ppb influent level)
- NSF/ANSI 58
Claims: Arsenic (Pentavalent)<=50 ppb Reduction, Uranium
For: Arsenic, Uranium
Other certifiers’ wording: Arsenic (Pentavalent)<=300 ppb Reduction; Arsenic (V) (300 ppb influent level)
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. Arsenic, uranium, nitrate, total trihalomethanes (TTHM), chromium (total), fluoride and haloacetic acids (HAA5) results here are Pennsylvania’s own from 2020 on, with EPA’s national file for 2012 to 2019. Westgate Water System’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 5, 2020 to March 17, 2026; Pennsylvania’s PFAS results run from March 13, 2025 to Dec. 9, 2025.
