      Sorry Harry, I think I might have you confused, my bad mate. What I was trying to say is that *I* use carbon treatment, not the
      actual water out of the tap. Is that better...? 8-)

      Are you sure about that, Tim? Most areas of Oz, particularly Qld
      coast, still use sand filters, chlorine disinfectant & floc
      technology. Some (like where I live) have introduced
      microfiltration. But only in problem areas is carbon used, because
      of the costs...

      HYPERLINK "http://www.waterquality.crc.org.au/consumers/Consumersp9.htm"http://www.waterquality.crc.org.au/consumers/Consumersp9.htm

      Activated carbon is the most widely used adsorbent material in water
      treatment, because it is highly effective in removing taste and
      odour compounds and algal toxins. It can be used as a powder or in
      granular form.

      In Australia, there has only been limited use of granulated
      activated carbon. In this treatment process, the activated carbon is
      usually placed in a column or filter and the water percolated
      through the bed of carbon granules. After some time the activated
      carbon will become saturated with the adsorbing material and will
      need to be replaced or regenerated. Current technology to regenerate
      the carbon granules involves heating in a high temperature furnace.
      Because of the cost of this regeneration process, it has not been
      used in Australia.

      If water contamination occurs only occasionally, a better approach
      is to add powdered activated carbon to a conventional
      coagulation/flocculation process when the problem arises. The carbon
      is collected in the filters and then discarded with the normal water
      treatment plant sludge. Such intermittent dosing of activated carbon
      powder is used in Australia at numerous locations that have problems
      with blue-green algal blooms.

      The use of activated carbon is a very costly and can be justified
      only when there are particular problems with toxins or taste and
      odour compounds.

      Phone your local council and ask them what the setup is.

      regards Harry
