How long must a Precautionary Boil Water Advisory or Boil Water Notice be in effect?

An advisory or notice will remain in effect until test samples show the water is safe to drink. Testing for bacteria requires 18 to 24 hours to complete, depending on the type of test used. The samples are incubated to actually grow bacteria, if any are present. As a result, advisories and notices will be in effect for at least 24 hours.
