   It should remove all of this and more; but be careful, because EDI looks   
   like overkill in your case and you may end up poisoning your plants with   
   too clean water. Have you considered something less strict, such as   
   reverse osmosis?

   Chemists, chemical engineers, material scientists - desalination is   
   actually pretty huge field of science.
