Qwave, if I may interject a bit. H2o will become a much bigger issue as we move forward for some of these reasons:1)useage increases,quantities are fixed 2) Decisions are politicized,often based on emotion,rather than empirical fact.3)The cheese has not yet become adequately binding to initiate the available technology to increase h2o supplies. I am not sure how to play any of this in regard to equities but I can guarantee that equity may have little to do with the ultimate solutions.
