What is the main purpose of the National Primary Drinking Water Regulations?

The main purpose of the National Primary Drinking Water Regulations is to protect public health by limiting contaminants in drinking water. These regulations are set by the Environmental Protection Agency (EPA) and serve to safeguard the drinking water supply from harmful substances that can adversely affect human health. By establishing maximum allowable levels for various contaminants, the regulations aim to minimize the risks associated with waterborne diseases and chemical exposure.

This focus on public health distinguishes these regulations from other potential priorities such as aesthetic qualities or operational guidance. While taste standards and aesthetic improvements can enhance the drinking experience, they do not address the critical issue of health protection, which is the foremost concern of the primary regulations. Additionally, while guidance for water system operators is important for effective management and compliance, it is not the central purpose of these regulations. The overarching goal remains the prevention of illness and promotion of safe drinking water for all consumers.
