The Safe Drinking Water Act has set water quality standards for which categories?

The Safe Drinking Water Act (SDWA) establishes comprehensive water quality standards to ensure that public drinking water is safe for consumption. These standards cover a broad range of contaminants to protect public health. The correct response includes physical, chemical, radiological, and bacteriological categories, reflecting the multifaceted approach that the SDWA takes toward water quality.

Physical standards pertain to the appearance and taste of water, such as turbidity and color. Chemical standards include a variety of substances that can affect health, such as heavy metals and disinfectants. Radiological standards address the presence of radioactive materials, which can pose significant health risks. Finally, bacteriological standards target harmful microorganisms, helping to prevent diseases from pathogens in drinking water.

This comprehensive approach ensures that drinking water is evaluated against multiple criteria, minimizing risks to human health and ensuring access to safe drinking water for all.
