    Aluminum oxide cannot be present in dissolved form in water, it is
    100% non-soluble.  A very fine powder could be transported by water
    as a slurry, suspension, or colloid though.

      Don't know if you can answer this Marshall but I'll
        ask anyway out of curiosity.
        

        
        Is it possible for the waste byproduct of aluminium
          processing plants added to mains water supply to contain any
          aluminium oxide - at all?

            Alumina is aluminum oxide, a very hard ceramic.  It has a
            wide range of uses, from grinding abrasive, plastic filler,
            electrical insulator (like for spark plugs), filter medium,
            paint filler/pigment, catalyst, and gemstones, such as
            rubies and sapphires.

              Hi Joe,

                Is alumina the same as aluminum?  If it is wouldn't that
                be a poor choice to shower in?

                Thanks.
