Water Distribution Grade 1 Certification Practice Exam

Which two agencies are tasked with approving laboratory analytical methods for drinking water?

1. The Food and Drug Administration and the Arizona Department of Water Resources

2. The U.S. Environmental Protection Agency and the Arizona Department of Health Services

3. The U.S. Geological Survey and the Arizona Department of Environmental Quality

4. The National Institutes of Health and the Arizona Water Management Division

The correct answer is: The U.S. Environmental Protection Agency and the Arizona Department of Health Services

The U.S. Environmental Protection Agency (EPA) and the Arizona Department of Health Services (ADHS) are the correct agencies tasked with approving laboratory analytical methods for drinking water. The EPA is a federal agency responsible for regulating and ensuring safe drinking water across the United States. It sets national standards for drinking water quality and approves the methods used for the analysis of water samples to ensure they meet these standards. The Arizona Department of Health Services plays a critical role at the state level, implementing federal regulations and setting additional guidelines as necessary to protect public health. By collaborating with the EPA, ADHS is involved in the approval of laboratory methods that detect various contaminants in drinking water to maintain safety and compliance with health standards. Other agencies listed may have roles related to water management or research but do not specifically focus on the approval of laboratory methods for drinking water analysis, making them less relevant in this context.
