It is generally safe to drink tap water in Sydney. Sydney's tap water is treated and tested rigorously to comply with the Australian Drinking Water Guidelines, ensuring it meets high safety and quality standards. The water is disinfected with chlorine and chloramine, and fluoride is added for dental health. While trace amounts of some chemicals and "forever chemicals" (PFAS) have been detected, authorities maintain that the tap water is safe for consumption, though there is no such thing as naturally pure water. Overall, the water supply undergoes extensive monitoring from source to tap to keep it safe for drinking.
