More colleges join bottled water ban

More than 90 schools have eliminated the item, citing environmental concerns.

Bottled water is coming under attack on college campuses.

More than 90 schools, among them Brown University and Harvard University are banning the sale or restricting the use of plastic water bottles, unnerving the $22 billion retail packaged-water industry in the U.S. The University of Vermont is the latest to join the movement, announcing in January it would stop sales early next year.

Freshmen at colleges across the country are being greeted with stainless-steel bottles in their welcome packs and encouraged to use hydration stations where free, filtered water is available. Brown, which used to sell about 320,000 bottles of water a year in vending machines and campus stores, ended sales in dining halls in 2010. Harvard and Dartmouth College are installing hydration stations in new buildings to reduce trash.
