Unbeknownst to many, bottled water typically shares the same source as municipal water, meaning that bottled water is not a cleaner or safer alternative to tap water. Not to mention the risk of microplastics, BPAs, phthalates, and other toxic chemical compounds leaching into your water from the plastic containers it is housed in that can cause long-term health problems.
For example, the world's largest bottled water brand, Aquafina, has been challenged by Corporate Accountability International, and is now changing its label to address claims of misleading marketing practices. The "P.W.S." that has been on Aquafina's label will now be spelled out as "Public Water Source," which means it comes from the same supply as your tap water... tap water that has chlorine, fluoride, impurities, and other contaminants that affect your water quality, taste, and safety. And all this with a healthy dose of microplastics from the plastic water bottles they're housed in!
And it is not just Aquafina; the water industry is rife with companies filling their bottles with tap water and passing it off as high-quality spring water through sneaky marketing techniques. In reality, most bottled water has simply passed through the same water treatment plant as the water that flows freely from your tap and is then sold back to you at a premium price on the grocery store shelves.
