+Is Long Beach, CA tap water safe to drink in 2024?

The 2024 Consumer Confidence Report for the Long Beach, CA water utility lists 5 contaminants at or above the federal limit: Lead, Arsenic, Bromate, Uranium, and NDMA. Whether that means the water is "unsafe" depends on which contaminant, how long the exposure, and individual health factors. The table on this page shows the measured value, the federal threshold, and the regulated statistic used for compliance.

+What contaminants are in Long Beach, CA tap water?

44 contaminants were measured in Long Beach, CA's 2024 Consumer Confidence Report, spanning pfas ("forever chemicals"), metals, and disinfection byproducts. 20 have an enforceable federal limit; the rest are detected but unregulated. Every measured value, in the utility's own units, is on this page.

+Which contaminants exceed federal limits in Long Beach, CA tap water?

5 contaminants in Long Beach, CA's 2024 report sit at or above the federal limit: Lead (450.0× the limit); Arsenic (375.0× the limit); Bromate (31.5× the limit); Uranium (7.0× the limit); NDMA (2.5× the limit). The EPA enforces these limits against the regulated reporting statistic — typically a running annual average or 90th percentile — not a one-off sample spike.

+What is the worst contaminant in Long Beach, CA tap water?

The contaminant with the highest measured value relative to its federal limit in the 2024 report is Lead, at 450.0× the federal threshold. It belongs to the metals family of contaminants.
