The concept of water resources is multidimensional. It is not limited only to its physical measure (hydrological and hydrogeological), the ‘flows and stocks’, but encompasses other more qualitative, environmental and socio-economic dimensions.

Fresh groundwater is used for many important purposes, with the largest amount going toward irrigating crops, Local city and county water departments withdraw a lot of groundwater for public uses, such as for delivery to homes, businesses, and industries, as well as for community uses.

Industries and mining facilities also used a lot of groundwater. The majority of water used for self-supplied domestic people who supply their own home water, usually by a well and livestock purposes came from groundwater sources.
