The National Ground Water Association (NGWA), headquartered in Westerville, Ohio, is a membership-based nonprofit organization.. Founded in 1948, the organization is composed of United States and international groundwater professionals in four membership divisions: water well contractors, scientists and engineers, manufacturers, and suppliers.
These Wellhead Protection Programs must specify the duties of State agencies, local governmental entities, and public water supply systems to develop and implement wellhead protections. Identification of the area that needs wellhead protection must be based on the hydrologic and geologic information on groundwater flow, recharge, and discharge.
Groundwater banking is a water management mechanism designed to increase water supply reliability. [1] Groundwater can be created by using dewatered aquifer space to store water during the years when there is abundant rainfall .
Use of groundwater, especially for irrigation, may also lower the water tables. Groundwater recharge is an important process for sustainable groundwater management, since the volume-rate abstracted from an aquifer in the long term should be less than or equal to the volume-rate that is recharged.
Sustainable groundwater management: the management and use of groundwater that can be maintained without causing an undesirable result. Undesirable results include any of the following: Persistent lowering of groundwater levels; Significant and unreasonable reductions in groundwater storage; Significant and unreasonable saltwater intrusion
The amount of groundwater right is based on the size of the surface area where each landowner gets a corresponding amount of the available water. Once adjudicated, the maximum amount of the water right is set, but the right can be decreased if the total amount of available water decreases as is likely during a drought.

Water located beneath the ground surface An illustration showing groundwater in aquifers (in blue) (1, 5 and 6) below the water table (4), and three different wells (7, 8 and 9) dug to reach it. Groundwater is the water present beneath Earth's surface in rock and soil pore spaces and in ...
Groundwater is also used by farmers to irrigate crops and by industries to produce everyday goods. Most groundwater is clean, but groundwater can become polluted, or contaminated as a result of human activities or as a result of natural conditions. The many and diverse activities of humans produce innumerable waste materials and by-products ...
