What standard must drinking water meet to be deemed safe for public consumption according to the Safe Drinking Water Act?

To be deemed safe for public consumption under the Safe Drinking Water Act, drinking water must meet both primary and secondary maximum contaminant levels. Primary maximum contaminant levels are legally enforceable standards that protect public health by limiting the levels of specific contaminants that can adversely affect human health. These contaminants can include bacteria, viruses, inorganic chemicals, pesticides, and more.

On the other hand, secondary maximum contaminant levels are non-enforceable guidelines related to aesthetic considerations such as taste, odor, color, and other factors that do not pose an immediate health risk but can still affect the quality and acceptability of drinking water.

Meeting both sets of standards ensures that water is not only safe for consumption from a health perspective but also pleasant and acceptable for everyday use. This holistic approach reflects the goal of the Safe Drinking Water Act to ensure comprehensive protection of public health regarding drinking water quality.
