The ‘GHI’ of Water Pollution

G

Groundwater describes any kind of water “trapped” underneath the surface of the earth. It can be flowing water, permafrost or water mixed with other liquids. Groundwater is not static, in the sense that it stays a a particular level in the earth, it travels with time and move down the water table. Groundwater is normally of a very good quality because of the natural filtering that occurs when then the water passes through the ground.
