What water bottle companies use tap water?

There are no major water bottle companies that use only tap water. Some companies, like Aquafina and Dasani, use purified tap water, which means that the tap water has undergone a filtration or reverse osmosis process to remove impurities and contaminants. Other companies, like Nestle Pure Life and Evian, use spring or groundwater sources that are naturally filtered through layers of rock and soil.
