Groundwater is an extensive, concealed and inaccessible resource, and (in contrast to surface water) changes in quantity and quality are often very slow processes occurring below large land areas. These changes cannot be determined by simple one-off snapshot surveys alone, and require more elaborate monitoring networks and data interpretation. The primary goal of aquifer management is to control the impacts of groundwater abstraction and contaminant loads, and monitoring aquifer response and quality trends provide key inputs for this goal. The evaluation of groundwater issues and the implementation of management solutions require hydrogeological data that are in part baseline and in part time-variant in character-the collection of the time-variant component is what is usually considered groundwater monitoring. Groundwater monitoring thus comprises the collection, analysis and storage of a range of data on a regular basis according to specific circumstances and objectives.
