State drinking water records
Arkansas drinking water systems
664 community water systems serve Arkansas and are listed below under 75 counties and on the pages of 597 cities and towns. Their own population figures add up to 3,050,790 people, a sum that counts people twice where one system sells water to another.
221 of them (33%) had at least one health-based violation in the last 10 years. 122 systems still have one unresolved.
362 rely mainly on groundwater and 302 on surface water, counting water bought from other systems.
586 systems filed a lead service line inventory listing 260 lead lines, 11,309 galvanized lines that must be replaced and 482,767 lines of unknown material.
2 systems are placed by the county their records name: EPA has no service area map for 1 of them, and 1 has one that does not line up with its own records.

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.
