What type of water has been treated and is safe for drinking?

Tap water is the type of water that has undergone treatment processes to ensure it is safe for drinking. Municipal water systems typically treat tap water through various methods, including filtration, disinfection (often involving chlorine or UV light), and sometimes fluoridation. These processes are regulated by health standards to ensure that the water is free from harmful contaminants, making it suitable for consumption by the public.

Spring water, mineral water, and distilled water can also be safe for drinking. However, they are not necessarily subject to the same rigorous treatment and monitoring processes as tap water from municipal sources. Spring water is sourced from natural springs and may require minimal processing, while mineral water contains minerals and is sourced from groundwater. Distilled water, on the other hand, is water that has been boiled into vapor and condensed back into liquid, removing minerals and impurities but is not treated in the same way as municipal tap water. Thus, while all these types can be safe to drink, tap water is the one that is specifically treated through a comprehensive system to meet public health standards.
