The short answer

Nothing in EPA’s and Pennsylvania’s records for this utility is above a health goal. That covers PFAS, plus nitrate, arsenic and other regulated chemicals, 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 Feb. 17, 2025 to Oct. 14, 2025.

Nitrate, total trihalomethanes (TTHM), arsenic, chromium (total), fluoride, haloacetic acids (HAA5) and uranium: Pennsylvania’s own results, samples taken from Jan. 6, 2020 to July 13, 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.

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.

Below EPA’s limits2

Nitrate

Comes from the source

Below EPA’s limits

6.0ppm

Highest sample; found in 28 of 28

2026 average: 5.9 ppm

The highest sample, in 2026, was 6.0 ppm, below EPA’s legal limit of 10 ppm. That was also the latest year on file, and its three samples averaged 5.9 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 5.8 ppm, in 2019.

Total trihalomethanes (TTHM)

Forms or is added in treatment

Below EPA’s limits

7.5ppb

Highest yearly average, 2022 to 2025

Averaged by year, the highest was 7.5 ppb, in 2025, below EPA’s legal limit of 80 ppb. That was also the latest year on file.

What this report can’t tell you

Everything else. Nitrate, total trihalomethanes (TTHM), arsenic, chromium (total), fluoride, haloacetic acids (HAA5) and uranium results here are Pennsylvania’s own from 2020 on, with EPA’s national file for 2012 to 2019. Trotter Farms’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 Jan. 6, 2020 to July 13, 2026; Pennsylvania’s PFAS results run from Feb. 17, 2025 to Oct. 14, 2025.

Testing your own tap

Trotter Farms’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.
