Which federal organization oversees the Safe Drinking Water Act?

The correct answer is the Environmental Protection Agency (EPA). The Safe Drinking Water Act (SDWA) was enacted in 1974 to protect public health by regulating the nation's water supply. The EPA is responsible for setting the standards for drinking water quality and overseeing the implementation of these standards at the federal, state, and local levels. This includes ensuring that public water systems meet safety requirements and are regularly monitored for contaminants that could affect health.

The other organizations mentioned do not have oversight of the Safe Drinking Water Act. The Centers for Disease Control and Prevention (CDC) focuses on public health and disease prevention but does not regulate water quality under the SDWA. The Food and Drug Administration (FDA) deals mainly with the regulation of food and beverages, and while it plays a role in ensuring bottled water safety, it does not oversee the overall performance of public drinking water supplies. The Federal Emergency Management Agency (FEMA) responds to disasters and emergencies, including those that may affect water safety, but it does not regulate water quality like the EPA does.
