Graham and Ashkahn got cornered at Rise with a question from one of the attendees, a float center owner named Gina. And even though the event is over, it'd be a shame to not share this episode. They answer all her questions and concerns about municipal water systems and the levels of filtration that should be done when using water straight from the tap (which probably almost everybody does), they also talk about what you really need to worry about in your tap water.
