TO GO WITH AFP STORY: US-environment-water by Rob LeverThis June 29, 2008 photo illustration shows a woman drinking bottled water. A debate over water is boiling over in the United States and elsewhere amid growing environmental concerns about bottled water and questions about safety of tap water. The US Conference of Mayors in June passed a resolution calling for a phasing out of bottled water by municipalities and promotion of the importance of public water supplies. While largely symbolic, the vote highlighted a growing movement opposing regular use of bottled water because of its plastic waste and energy costs to transport drinking supplies.
