A factory provides drinking water from its well for its employees. What type of public water supply is it classified as?

The scenario describes a factory that provides drinking water from its well specifically for its employees. This setup classifies the water supply as a Non-transient Non-community public water supply.

Non-transient Non-community supplies are those that serve a specific population of people, such as employees or students, who do not change frequently. In this case, the employees of the factory are a stable group that uses the water regularly, qualifying the supply under this classification.

Community supplies, on the other hand, serve the general public at residences and typically do not apply to workplaces like factories. Transient Non-community supplies cater to a transient population—people who do not stay at the water supply site for a long duration, like travelers in a gas station or restaurants. Since the factory's water is primarily for its consistent workforce, the accurate classification solidifies the understanding of how public water supplies are categorized based on user stability and type.
