The water I've been drinking comes from the process of the water cycle. For example the water storage in the ocean EVAPORATES in to the atmosphere so the water we drink will evaporate up into the air leaving the vapors to build up and turn into clouds, that process is called CONDENSATION after the clouds build up more and more it rains,snow,sleet or hail , this process is called PRECIPITATION.
As the cycle continues we experience different taste in our water that we drink daily. Because of the different times and ways how it precipates.
