Which term defines a Public Water System that supplies water to the same population year-round?

• A. Public Water System
• B. Community Water System
• C. Noncommunity Water System
• D. Seasonal Water System

Answer: (B)

In this topic, the important idea is how public water systems are categorized by who they serve and for how long. A community water system is defined as one that provides water to the same population year-round at a fixed locale. That means residents and businesses in a town or city receive water every day, throughout the year, from that system.

The other terms fit different situations. A public water system is the broad umbrella that includes all systems. A noncommunity water system serves places where people don’t live year-round—think workplaces, schools, churches, or recreational facilities, often with varying or seasonal use. A seasonal water system describes a system that operates only during certain seasons, so it isn’t supplying water year-round.

So, because the question specifies year-round delivery to the same population, the correct term is community water system.
