Which statement is true regarding the primary Drinking Water Standards?

The statement that accurately describes the primary Drinking Water Standards is that they apply to both community water systems and non-transient, non-community water systems. The U.S. Environmental Protection Agency (EPA) has set these standards to ensure that public water systems deliver safe drinking water.

Community water systems serve the same population year-round, while non-transient, non-community systems serve a non-residential population, such as schools or factories, that routinely uses the same water source for at least six months of the year. This reflects the intent of the regulations to safeguard public health across both types of systems.

The emphasis on both system types indicates a broad regulatory approach to protect consumers from potential contaminants, ensuring that water quality does not vary based on the type of public water system. Addressing both community and non-transient non-community systems ensures a wider scope of public health safety regarding drinking water quality.
