Non-Transient Non-Community Water Systems serve which of the following populations?

• A. Individuals on a short-term basis
• B. The same group of at least 25 people over six months a year
• C. Tourists in various locations
• D. Only residents of mobile home parks

Answer: (B)

Non-Transient Non-Community Water Systems are designed to provide water to the same group of people consistently over a period of time. This typically includes facilities such as schools, factories, and hospitals where the same population—at least 25 individuals—uses the water supply for at least six months of the year. Understanding this classification is important for recognizing how water systems are regulated and managed, as the requirements for safety and monitoring may differ based on the nature and stability of the population served. In contrast, the other options describe scenarios involving short-term usage or transient populations, which are not consistent and do not fit the definition of Non-Transient Non-Community Water Systems. Therefore, the focus on a stable, defined group of users for a significant part of the year is what makes this answer correct.
