Which of the following is NOT one of the established water quality standards in the Safe Drinking Water Act?

The Safe Drinking Water Act (SDWA) establishes a framework for regulating public water systems to ensure safe drinking water for the public. Under this act, several specific categories of water quality standards are recognized, including chemical, bacteriological, and radiological standards.

Chemical standards refer to the allowable limits of harmful chemicals and pollutants in drinking water, such as heavy metals and pesticides. Bacteriological standards focus on the presence of microorganisms, including bacteria, viruses, and parasites that can affect human health. Radiological standards are concerned with the presence of radioactive substances in drinking water.

Nutritional standards are not included in the SDWA because the act focuses on contaminants and pollutants that may pose health risks rather than the nutritional content of water. While the nutritional aspects may be relevant for food and beverages or for dietary considerations, they do not fall under the regulatory framework established by the SDWA for ensuring the safety and quality of drinking water. Therefore, the option stating nutritional standards does not align with the established categories in the Safe Drinking Water Act.
