Freshwater Website: Groundwater (What is groundwater?)
The level below which all the spaces are filled with water is called the water table. Above the water table lies the unsaturated zone. Here the spaces in the rock and soil contain both air and water. Water in this zone is called soil moisture. The entire region below the water table is called the saturated zone, and water in this saturated zone is ...

WFD. The implications of these controls to the UK, particularly in relation to nitrate and pesticide concentrations in groundwater, may be very serious. Nitrate pollution of the unsaturated zone in the Chalk and Permo-Triassic sandstone aquifers, due to application of agricultural fertilizers is widespread and a store of decades of high level nitrate loadings is held in this ...
