How is water naturally filtered underground?

In nature, water is filtered through layers of soil, sand, rock, and other natural materials like leaves. Surfaces where water can penetrate are called permeable surfaces. As impervious (or impenetrable) surfaces increase in urban areas, this leads to less natural water filtration.

What is river side called?
