Boil water advisories in Missouri

We read this state's own advisory list

The agency that publishes it

Missouri DNR

What that list covers

Boil orders published statewide by the Missouri Department of Natural Resources as the Socrata dataset DNR-WPP-Boil Order Report (j2a5-itxh). The whole dataset held 7 records on 2026-08-22, each of them a small private system, and the response dated the data 3 days old at source. This is the list Missouri publishes; it is not an inventory of every boil order in force in the state, and a short or empty list is never evidence that Missouri has none. The dataset carries no status field, so a lift is signalled solely by a record disappearing from a later fetch.

We read it on an hourly cycle. Last successful read 2026-08-31T04:20:08.178+00:00

Questions about this page

Does this page list every boil water advisory in Missouri?

It lists what Missouri DNR's own statewide list showed when we last read it, one entry per water system rather than one per notice. A notice a utility issued directly, and never sent to that list, would not appear here.

Where are boil water advisories for Missouri published?

Missouri DNR publishes them, and its own statewide list is the list we read into this page on an hourly cycle. The link to it is on this page.

How many water systems does this page cover?

Our database holds 650 public water systems in Missouri. 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.

Is anything on this page a verdict about whether the water is safe?

This is not a statement that your water is safe. It means the state's list did not name your system. Your utility is the authority for your own water.
