Definition
This variable indicates the source of the dwelling's water supply and whether the unit supplied its own water via an individual well or was attached to a larger public or private system. A "public system" or "private company" is any public or private system or well serving 6 or more units. An "individual well" serves 5 or fewer units and may be located on either the unit's property or an adjacent property. "Other source" includes water from springs, creeks, rivers, or cisterns.
