Which agency primarily oversees sanitation regulations in the United States?

The Environmental Protection Agency (EPA) is the primary agency responsible for overseeing sanitation regulations in the United States. The EPA establishes standards and regulations to protect human health and the environment, which includes air quality, water purity, and waste management. This agency plays a critical role in regulating pollutants that can affect sanitation and public health, ensuring that drinking water and wastewater systems meet safety standards.

In the context of sanitation, the EPA's guidelines help ensure that communities maintain hygienic conditions, which are vital for preventing disease outbreaks. Additionally, the EPA conducts research and provides technical assistance to support best practices in sanitation and waste management.

While the other agencies have important roles related to health and safety, they each focus on specific areas: OSHA primarily focuses on workplace safety, the CDC monitors public health and disease control, and the FDA oversees food safety and pharmaceuticals. Although all contribute to elements of sanitation, the EPA is specifically tasked with regulating and enforcing standards directly related to environmental sanitation.
