Los Angeles / Water guide / 1 of 3
Read your local water information
A practical guide for your home. This is utility context and equipment guidance, not an individual water test.
LADWP’s 2025 Drinking Water Public Health Goals Report covers 2022–2024 and reports compliance with enforceable drinking-water standards. Health-goal exceedances are different from violations of legal drinking-water limits. Your supplier and property need their own assessment.
Confirm the provider for your address
Confirm the provider shown on your water bill. Greater Los Angeles has multiple water suppliers. A city-wide utility report is not a test of your household plumbing or tap.
Utility reports describe a supply and a period of testing. They are not a test of the water at your tap today. Follow current utility notices and use appropriate laboratory testing for a specific safety concern.
