This post explores the concept of maturing water and possible origins of hard water. Water has been around since the Earth was born. It cleans itself in order to keep thriving for all life to benefit from. In the listed reference, Pangman & Evans suggest that water might even be created deep within the Earth:
"Hydrogen is abundant at the core of the Earth which is like the hot Sun. Hydrogen is released as rocks interact with microbes and as they decompose in the heat. Oxygen is available inside the Earth too—from mineral decomposition and from the surface as the Earth breathes through vents."
From this mixture, steam and water are formed. Deep within caves water seems to seep in from below as underground rivers and lakes are formed, and it eventually rises up through natural springs as freshwater. The water rises from the Earth’s core because it seeks a cooler environment and because it is hydrogen-rich, making it lighter and easily elevated.
Hard water may occur in our homes when immature water is pumped from the ground before it completes its cycle. The energy of the water reacts with minerals differently before it is mature, which is why homes with hard water show mineral deposits in and around their water facilities. Structuring the water allows it to regain its appropriate state and be more efficient.
