Shouldn’t we have learned by now that refilling water bottles is the way to go? The real reason to drink bottled water is because of its purity, right? Yet the Los Angeles Times found that about 64% of bottled water is filtered tap water, and Consumer Reports found that bottled water can contain heavy metals and bacteria. Even if bottled water comes from a spring, it must still undergo filtration and ozonization, meaning it is no longer “pure” spring water. Most spring water is also said to be minimally treated to maintain its “natural” characteristics, whatever those are.
