If your water is chlorinated ( typically city water) is not the question we should be asking....
What we should be asking is Acidic or Alkaline ... THAT is the question....
I wrote the other day the no matter how much water I drink, my gout does not get better.... That is because my TAP water (chlorinated) - city of philadelphia - has a PH of 6.0 - to 6.25.... ACIDIC
No wonder why it did not help.... So I added a pinch of baking soda.... JUST a pinch.... that brought the water to 7.5 .... just alkaline....
I would suggest you get some litlus paper or PH stix from ph-ion.com and test your water...
Hope this helps!
