What is a Transient Noncommunity Water System (TNCWS)?

A Transient Noncommunity Water System (TNCWS) is defined as a water system that serves the public but not the same individuals for more than six months. This type of water system typically supplies water to places like gas stations, campgrounds, or hotels where people may only stay temporarily. It is important for TNCWS to adhere to specific regulations and monitoring requirements to ensure the safety and quality of the water provided, despite the transient nature of its user base.

In contrast, options that describe a system serving the same group of people year-round, one that serves individuals for more than six months, and a permanent supply for community residents are all characteristic of community water systems, which have different regulations and responsibilities regarding water safety and quality management.
