Most people in Arizona receive their drinking water from large municipal water delivery systems that rely on surface water sources such as rivers, lakes and reservoirs. Many others in the state's smaller and rural communities depend on private water sources such as wells and aquifers.

In either case, the Arizona Department of Environmental Quality's Safe Drinking Water Program works to ensure the water they are served is clean and healthy through a wide variety of programs designed to prevent, detect and correct any possible contamination of drinking water or drinking water sources.
