Of course not. Water, acting as a solvent, reaches into every cell to absorb and carry away the poisons that are formed as a part of the life process. This cleansing process cannot function properly when the water itself is polluted. The average person's kidney filters about 400 gallons of blood a day. It's rather common sense that we can greatly aid this process by consuming pure water.
Water helps transport substances in the body.
As a solvent, water helps prepare substances for transport across cell membranes and for distribution throughout the body by way of the circulatory and lymph systems. When the water is filled with contaminants, its ability to dissolve bodily substances is impaired. Water keeps body chemistry regulated and functioning properly. Without enzymes and trace minerals, the metabolic activities in the body cannot take place. Contaminants in the drinking water will interfere with these crucial processes.
