I see too many problems with the scientific studies of the water in sense that it's blind to the whole. The studies tries to divide and conquer the smaller parts that defines the properties of the water.
My observations are the water works as whole when in interaction with drinking or feeding to the plants. The best water for drinking is spring water.
You have to keep in the mind that water is part of a bigger picture. The Science always ignores the bigger picture. That's why I ignore those studies that are based on divide and conquer principle.
