I'll Thank everyone here for their input.
I was just curious to know if there was any chemistry happening besides what 
has been mentioned.
Cheers

Cool water holds more dissolved gasses than warm. so 'outgassing' happens when 
water warms up and bubbles will form on below liquid surfaces.  If these gases 
aren't allowed to vent off, they will probably re-absorb when the temperature 
drops again.  

Evaporation/Condensation inside the container also happens with temperature 
cycles.

    yes... sounds like condensation.  I
      haven't noticed that on mine...but then I go thru it pretty
      quickly.   Good info to know.  I just love this site.  Glad I
      found it.

      Evaporation and Condensation fits.

          @ Patricia...I'm not referring to any change in
            quality or change in meter readings or coloration etc, just
            the water droplets which keep appearing inside the glass
            storage vessels.  Minimal air space between product and lid,
            but I also have half empty containers in storage for a
            couple of years and consequently more room to observe these
            droplets being created and enlarging.  I'm talking quite a
            while in storage here though.
            

            
            @ Sandee...I have never used any coloured glass, just
              clear glass containers.  
            

            
            "Sweating"...I suppose you could call it that, little
              beads of water droplets collecting around the inside of
              the vessel, and the longer the time in storage, the larger
              those droplets get, eventually resulting in some running
              down the glass and returning back into the solution no
              doubt.
