Name key U.S. environmental laws related to water quality and public health protection.

• A. Clean Water Act, Safe Drinking Water Act, NEPA, and RCRA (plus state equivalents)
• B. Only Clean Water Act
• C. Federal Insecticide, Fungicide, and Rodenticide Act
• D. International treaties unrelated to water

Answer: (A)

Protecting water quality and public health in the United States relies on several major laws that together cover surface and drinking water, as well as how federal actions and waste management affect water resources. The Clean Water Act sets the framework for protecting surface waters by controlling discharges into rivers, lakes, and coastal areas through permit systems and water-quality standards, aiming to keep these waters safe for ecosystems and people. The Safe Drinking Water Act focuses specifically on drinking water supplies, establishing health-based standards for contaminants and overseeing drinking-water systems to prevent waterborne illnesses. The National Environmental Policy Act requires federal agencies to assess the environmental impacts of their actions, including effects on water resources, and to consider alternatives, so water quality and public health are part of federal decision-making. The Resource Conservation and Recovery Act governs the management and disposal of hazardous and non-hazardous wastes, helping prevent pollution of groundwater and surface waters from spills, leaks, or improper handling. Taken together, these laws—along with state equivalents—form a broad framework that protects water quality and safeguards public health.

Other options fall short because they don’t cover the full scope of water protection: one choice would omit drinking-water standards and waste-management safeguards; another centers on pesticide regulation rather than broad water-quality protection; and another points to international treaties that aren’t the primary U.S. domestic framework for water quality and public health.
