Boil water advisories in Louisiana
We do not read this state's advisories
We checked Louisiana Dept of Health's site on 22 August 2026, and it publishes its own list of active boil water advisories. We do not read that list into this page, so open it directly for what it shows now.

Questions about this page
- Does this page list every boil water advisory in Louisiana?
- No. We do not read Louisiana Dept of Health's advisories into this page, so nothing on it is a list of what is in force. What this page carries instead is where those advisories are published and which water systems our own database holds.

- Louisiana Dept of Health publishes its own list of active advisories, and this page links to it. We checked it on 22 August 2026.

- Our database holds 455 public water systems in Louisiana. That is a count of what is in our database, not a count of every public water system in the state. Advisories are counted by water system, keyed on the system's federal identifier, and never by the number of separate notices one system has been given.
