Is Reno Tap Water Safe? What Truckee Meadows Water Authority’s EPA Records Show
Truckee Meadows Water Authority, which serves about 442,000 people in Reno-Sparks (the Truckee Meadows), Nevada, reported PFOA, PFOS, PFHxS above the EPA limit in the EPA’s UCMR5 PFAS monitoring (2023-2025). That is the system’s own reported occurrence — “reported above the limit,” not “in violation”; enforcement of the PFAS limits phases in through 2029-2031. Its most recent EPA-record lead 90th-percentile was non-detect (below the reporting limit) — under the current 15 ppb action level. The system has 1 health-based violation on its federal SDWA record.

These are the highest samples in the state/EPA record for this system — a snapshot, not a current reading; the utility’s Consumer Confidence Report is the official current record.
