75 rely mainly on groundwater and 44 on surface water, counting water bought from other systems.

86 systems filed a lead service line inventory listing 0 lead lines, 2 galvanized lines that must be replaced and 31,106 lines of unknown material.

7 more systems are placed in Snohomish County, WA by the county their records name because they have no service area map that lines up with their own records, so they are listed apart and not counted here.

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.
