Summary

No federal limits exceeded in EPA data.

PFAS
Not detectedNone of 29 PFAS found above EPA's reporting limits in 4 samples (2023–2025).
Lead
Below action level7.1 ppb (parts per billion) at the 90th percentile: 9 in 10 homes sampled were at or below it. Action level 15 ppb, falling to 10 ppb in Nov 2027. Monitoring period ending Sep 2025. Your home's pipes can make yours higher.
Violations
Resolved1 health-based violation since 2016, most recently Nov 2021.
What you can do

PFAS (“forever chemicals”)

EPA UCMR 5: 1 entry point tested Feb 2024 to Dec 2024. "Average" is the highest entry-point average (non-detects counted as zero), the way EPA compares UCMR 5 results to the limits. ppt = parts per trillion. These results do not determine compliance.

Pennsylvania has its own PFAS limits. PFOA 14 ppt (this system's highest average: not detected), PFOS 18 ppt (this system's highest average: not detected). State compliance is judged on the state's own sampling, so ask the utility or the state program whether it meets them.

29 PFAS tested, 0 detected at least once. "Not detected" means below EPA's reporting limit (about 2 to 20 ppt depending on the chemical), not proven zero. PFAS not listed were not detected. The limits for PFHxS, PFNA, GenX and the Hazard Index were proposed for rescission in May 2026. That proposal is not final. Systems have until 2029 to meet the limits.

Lithium

Not detected in 4 samples (reporting limit 9 ppb). About lithium.

Lead and copper

Latest 90th percentile: 7.1 ppb lead (Jun 2025 – Sep 2025). Below action level

Lead comes from pipes and fixtures, not the source water, so it varies home to home. The 90th percentile means 9 in 10 sampled homes were at or below it. More on lead.

Health-based violations mean a contaminant exceeded a limit or a required treatment step was missed. Monitoring and reporting violations mean required tests or reports were late or missing, so the water's quality during that time is unknown. The total includes every violation in EPA's records, most of them paperwork.

Questions

Is Lebanon Water Authority water safe to drink?

Lebanon Water Authority had 1 health-based violation since 2016, all since resolved. EPA testing found no PFAS above the federal limits. Federal data can't tell you about your own pipes: lead comes from service lines and plumbing, so test your tap if your home was built before 1986. For the official word, read the utility's annual Consumer Confidence Report.

Does Lebanon Water Authority water have PFAS?

EPA tested Lebanon Water Authority for 29 PFAS between Feb 2024 and Dec 2024 and none were detected above the reporting limits (about 2 to 20 ppt depending on the chemical).

What is the lead level in Lebanon Water Authority water?

The most recent 90th-percentile lead result for Lebanon Water Authority is 7.1 ppb, for the period ending Sep 2025. The federal action level is 15 ppb, falling to 10 ppb in November 2027. The 90th percentile means 9 in 10 homes sampled were at or below this number. Individual homes can be higher.
