Boil water advisories in Alaska

Alaska: 12 water systems under an active boil water advisory.

We read this state's own advisory list

The agency that publishes it
Alaska DEC Drinking Water Program
What that list covers
Open boil-water and do-not-drink notices published statewide by the Alaska Department of Environmental Conservation as the ArcGIS layer "Boil Water and Do Not Drink Notice - Open". 64 rows covering 48 distinct water systems on 2026-08-22 — the layer carries one row per affected source facility, so the row count is not the advisory count. It holds open notices only: a lift is signalled solely by a record disappearing from a later fetch.

Do not drink this water. Boiling will not make it safe.

These systems are under a do-not-drink or do-not-use order, not a boil water advisory. The two are not interchangeable, and the difference decides what you should do.

Boiling kills bacteria and viruses. It does nothing to nitrate, arsenic or PFAS — it concentrates them, because the water leaves as steam and the contaminant stays behind. Treating one of these orders the way you would treat an advisory about organisms would make the water worse, not better.

Read the notice your own utility sent, and follow it. It names the substance, the area it covers, and what the utility is telling residents to use instead. Nothing here replaces that notice.

Active boil water advisories

Notices that have been in force for a long time

These systems have been under a notice for more than 90 days. The notices are still in force. They are listed separately so that a notice standing for years does not bury one issued today, and so that the people living under the standing notice are not left off the page.

Questions about this page

Does this page list every boil water advisory in Alaska?
It lists what Alaska DEC Drinking Water Program'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 Alaska published?
Alaska DEC Drinking Water Program 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 102 public water systems in Alaska. 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.
