If I'm not mistaken, one of the drawbacks of desalination is the toxicity of the highly concentrated crap that's left over. The world can only consume so much sea salt. Although I've never heard a good explanation as to why they can't dump the shit back into the ocean. Localized pockets of ultra salinity perhaps???
