Is Long Beach Tap Water Safe? What Long Beach Utilities’s EPA Records Show
Long Beach Utilities, which serves about 466,772 people in California, reported no PFAS above reporting limits in the EPA’s UCMR5 monitoring (2023-2025). Non-detect means not found above the EPA’s reporting floor in that round — not that the water was never tested again. Its most recent EPA-record lead 90th-percentile was 0.97 ppb — under the current 15 ppb action level.
