Does this page list every boil water advisory in Michigan?

No. We do not read Michigan EGLE'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.

How many water systems does this page cover?

Our database holds 655 public water systems in Michigan. 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.
