Natural Purification of Liquid Water on Earth
Before we dig into the main topic, it is important to have an idea over the water cycle in nature, therefore understanding how water quality is falling and then purifying.
The hydrological cycle is the cycling of water molecules from the ocean to the atmosphere, then to the land and back to the ocean, or the storage in various reservoirs.
Let’s elaborate on its journey now: water evaporated from the ocean eventually condenses as water droplets in clouds.
If the cloud grows large enough, the droplets coalesce and fall as precipitation, mostly as rain, sometimes as snow or ice when the temperature is very low.

74% of all water evaporated into the atmosphere falls as precipitation on the ocean, mostly in the tropics. 26% falls on the land. But the distribution of rainfall is very uneven.
Some of the water runs into streams, lakes, and rivers, which return the water to the ocean while some soaks into the ground (infiltrates) and becomes groundwater.
The water then can percolate deeper into the ground supplying water to subsurface reser
