Chancellor Mark S. Wrighton samples water at the Student Union Bottled Water vs. Tap Water Taste Test outside the Danforth University Center Oct. 22 while (from right) sophomore Jennifer O’Neill and freshman Nora Long look on. Test participants were asked to identify which of four identical cups contained St. Louis tap water and three different brands of bottled water: Ice Mountain, Aquafina and Dasani. The event, part of the Congress of the South 40’s Eco-Olympics during Campus Sustainability Week Oct. 20-24, was held to demonstrate that there is little difference in the taste of water from a bottle — which often ultimately ends up in a landfill — and water from a tap. This was part of an ongoing education effort being implemented as the University moves toward eliminating bottled water on campus.
