Water Distribution Grade 1 Certification Practice Exam

Which agency is primarily responsible for regulating drinking water quality in the United States?

1. CDC

2. EPA

3. FDA

4. OSHA

The correct answer is: EPA

The Environmental Protection Agency (EPA) is primarily responsible for regulating drinking water quality in the United States. The EPA sets national standards for drinking water to ensure that it is safe for public consumption. This agency enforces the Safe Drinking Water Act, which outlines the requirements for public water systems and establishes regulations to protect the quality of drinking water. The EPA conducts regular assessments of water quality and works to ensure that contaminants are controlled. It provides guidance to state and local authorities, who are often responsible for the day-to-day operations of water treatment plants and distribution systems. While other agencies mentioned play important roles in public health and safety, their focus areas differ significantly from drinking water regulation. For instance, the Centers for Disease Control and Prevention (CDC) focuses on disease control and health information, the Food and Drug Administration (FDA) regulates food safety and pharmaceuticals, and the Occupational Safety and Health Administration (OSHA) oversees workplace health and safety conditions. Thus, the EPA's dedicated role in setting and enforcing drinking water standards makes it the correct answer.
