Which type of water supply is classified as a Community Water Supply?

A Community Water Supply is defined by its service to a stable population over an extended period, which typically means serving the same group of residents year-round. This consistent service allows water operators to manage water quality and infrastructure effectively to meet the needs of a permanent population. In Indiana, as well as federally, community water systems are essential for ensuring that public health standards are maintained, since they provide drinking water directly to households.

The other types of supply mentioned do not fit this definition. A supply serving non-residents for less than 60 days indicates a temporary use and does not contribute to a community's long-term water needs. Similarly, a supply exclusively for industrial purposes would not serve the residential population and thus does not qualify as a community water supply. Lastly, a supply only for seasonal residents caters to transient users rather than a consistent population, furthering the distinction from a community water supply. Overall, the B choice underscores the critical aspect of continuity in service which characterizes community water systems.
