Groundwater: aquifers, wells and circulation

Year: 2005
From collection: Vital Water Graphics
Author: Delphine Digout, UNEP/GRID-Arendal
Description:
This graphic illustrates groundwater flow, two types of aquifers (confined and unconfined) and three types of wells (artesian; flowing artesian and a water table well in an unconfined aquifer). It shows how groundwater is circulated through the aquifers and how it is recharged. Groundwater represents one of the most important resources for drinking water for human consumption.
