The short answer
1 result is above EPA’s legal limit. The worst: Haloacetic acids (HAA5), above the legal limit. 4 health-based violations since 2016.
What was found
PFAS: Pennsylvania’s own results under its PFAS rule, entry point samples taken from March 6, 2024 to Sept. 9, 2026.
Haloacetic acids (HAA5), total trihalomethanes (TTHM), nitrate, fluoride, arsenic, chromium (total) and uranium: Pennsylvania’s own results, samples taken from Jan. 15, 2020 to Aug. 19, 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. | ||

Haloacetic acids (HAA5)
Forms or is added in treatment
50.3ppb
Highest yearly average, 2020 to 2026
2026 average: 24.4 ppb
Averaged by year, the highest was 50.3 ppb, in 2021, below EPA’s legal limit of 60 ppb. Its highest single sample was 82.7 ppb. In 2026, the latest year on file, its four samples averaged 24.4 ppb. EPA judges this limit at each sampling point, and recorded a violation for haloacetic acids (HAA5) at this utility in 2020. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 84.3 ppb, in 2015, and EPA recorded violations in 2013, 2015, 2016 and 2019.

What this report can’t tell you
Everything else. Haloacetic acids (HAA5), total trihalomethanes (TTHM), nitrate, fluoride, arsenic, chromium (total) and uranium results here are Pennsylvania’s own from 2020 on, with EPA’s national file for 2012 to 2019. Greater Johnstown WA Saltlick’s own annual report, which it must send you every year, has the contaminants this page does not show.
