Packed drinking water, often referred to as bottled water, is a widely consumed beverage worldwide, valued for its convenience, purity, and portability. It is typically sourced from natural springs, wells, or municipal water supplies, then subjected to rigorous purification processes to ensure it meets regulatory standards for safety and quality. These processes can include filtration, reverse osmosis, ozonation, and ultraviolet (UV) treatment to remove impurities, pathogens, and other contaminants.

In modern times, the popularity of bottled water has surged, driven by concerns over the quality of tap water, convenience, and lifestyle trends
