Groundwater Pollution Prevention and Porosity vs Permeability

Porosity is a measure of void spaces between particles in a layer, expressed as a fraction of the volume of void space divided by the total volume, written as a percentage between 0-100%.

Permeability refers to the ability of water to move between pore spaces in a material.

Groundwater recharge is the process of water entering an aquifer, often occurring at plant roots and known as a flux to the water table surface.
