Water is not packaged in aluminum cans because of consumer views. Plastic is clear, so you can see the "clear, pure water" inside. Metal cans are more often associated with beer and soda, and there's the distant association of metals with a metallic taste (something that doesn't happen as all aluminum cans are epoxy-lined to prevent corrosion). Some sparkling water is still packaged in aluminum cans, but the vast majority choose not to. Paper is probably the most ecologically friendly water packaging, followed by glass.
