86 systems filed a lead service line inventory listing 50 lead lines, 1,458 galvanized lines that must be replaced and 22,720 lines of unknown material.

1 more system is placed in Denton County, TX by the county its records name because it has no service area map that lines up with its own records, so it is 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.
