Are ground water tables renewable?
Two types of ground water tables can be identified, those that are refilled when it rains and those that were filled a very long time ago and are not renewed. 1. Renewable water tables As indicated on the first page, they are at risk, and not just due to pollution. Another major danger is the increasing pumping of water, which uses up most of it. As the population does not stop growing, and it has its needs, the unceasing collection of water does not even allow the water tables to fill, with the risk of drying out. Not forgetting another danger linked to the reduced volume, the waters coming from the surface are increasingly polluted, they proportionally contaminate the reservoir more easily and can make the ground water table unfit for human consumption. Finally, agriculture is also a threat at two levels. This has to do with exponential irrigation needs which make pumping multiply but also the use of a multitude of chemical products (like pesticides) which rain water will carry into
