Perversely, I think it would be such a huge problem, that it wouldn't be a problem for long... Either you don't get it, and you get sick and die, or you survive the first 6 - 18 months, and drinking water will be available again. Probably without the convenience, abundance and quality, but I think those things would follow.

It seems to me like it would take much longer to get CPAN fixed or start making new episodes of Futurama.
