Water can be glacial water, spring water, well water, purified water or just water from the public water supply (tap water). Many countries, especially developed countries, regulate the quality of bottled water through government standards, typically used to ensure that water quality is safe and labels accurately reflect the content of the bottle. In many developing countries, however, such standards are variable and are often less stringent than those of developed nations.
The Council of Defense of the Natural Sources, Sierra Club and the World Wide Fund for Nature have stressed the importance of consuming less bottled water, and there have been several campaigns against bottled water. Many of these campaigns claim that bottled water is no better than tap water. In addition, waste is generated: as Corporate Accountability International organizations say millions of plastic bottles end up in landfills.
