Which of the following is a water efficiency program initiated by the EPA?

• A. Save Our Water
• B. Green Home Program
• C. Smart Water Management
• D. California WaterWise Initiative

Answer: (A)

The Save Our Water program, initiated by the Environmental Protection Agency (EPA), focuses on promoting water conservation and efficiency practices among communities and individuals. It aims to educate the public on the importance of wise water use, especially in areas affected by drought or water scarcity. This initiative provides resources and guidelines to help promote sustainable landscaping practices that reduce water use while maintaining healthy ecosystems.

The other options, while they may have their own merits in the context of water conservation, are not specifically programs initiated by the EPA. For instance, the Green Home Program relates more broadly to sustainable living practices, the Smart Water Management initiative often refers to various state or local programs rather than a singular EPA-led initiative, and the California WaterWise Initiative is focused on specific regional efforts to enhance water efficiency in California. Therefore, Save Our Water is the most fitting answer as it clearly aligns with an EPA-initiated water efficiency program.
