State drinking water records
American Samoa drinking water systems
10 community water systems serve American Samoa and are listed below under 3 counties and on the pages of 5 cities and towns. Their own population figures add up to 48,601 people, a sum that counts people twice where one system sells water to another.
6 of them (60%) had at least one health-based violation in the last 10 years. 3 systems still have one unresolved.
9 rely mainly on groundwater and 1 on surface water, counting water bought from other systems.
Their lead service line inventories list no lead lines, no galvanized lines that must be replaced and no lines of unknown material.
10 systems have no service area map from EPA and are placed by mailing address.

Counties come from the counties EPA lists each system serving, matched to 2024 Census counties; where EPA lists none, from the county coded in the system's ID, its service area map, or its mailing address. A county holding at least a fifth of a system's service area map is added when at least a fifth of that map lies in those counties. Towns are the ones EPA lists and the Census places such a map covers, always inside those counties. In New England, where EPA's town names a whole Town, it is not matched to the village of the same name. A system is not listed in a county holding less than a fifth of its map, or in a county or town its map reaches when the map lies mostly outside the counties EPA lists, so a page can leave out a system that serves part of the area.
