good, fresh water is found in rivers & lakes....IF we haven't dumped sewage & industrial waste into it...trouble is, we have. Places in Southern Calfornia and Arizona, etc. are dependant on water which starts in Montana, Idaho, Colorado, etc....but there are a whole bunch of folks ahead of them who seem to want to use that water for drinking, power, irregation BEFORE it gets south....and yet they keep growing in Phoenix and trying to build golf courses...and complaining because Colorado & Wyoming don't allow it all to flow on down!

The ONLY solution for the long term is fewer people and less demand....now, imagine a politician campaigning on that platform.
