This post is made possible by Boxed Water. As always, I only take financial support from companies I think are doing good things. Support EcoCult by supporting them! A few years ago, I was visiting a friend in Denver. He showed me his super duper fancy water filtration system. "You wouldn't believe the stuff that is in our water," he said as he stood next to the countertop machine that looked both heavier and more expensive than a Kitchen-Aid mixer. "When this is finished purifying the water, there's all sorts of crud left behind." I was skeptical. After all, tap water is sacrosanct to the environmental set. When a former lover ordered bottled water at breakfast, my respect for him plummeted. Who orders bottled water in New York City? Hello, our tap is some of the finest in the world! But in light of the Flint water disaster, I wanted to revisit this view and get an updated answer. And what I found totally surprised me!
