Phreatodrobia Punctata
''Phreatodrobia'' is a genus of very small or minute freshwater snails with a gill and an operculum, aquatic gastropod mollusks in the family Lithoglyphidae.Hershler R. & Thompson F. G. (1990). "''Antrorbis breweri'', a new genus and species of hydrobiid cavesnail (Gastropoda) from Coosa River Basin, northeastern Alabama". ''Proceedings of the Biological Society of Washington'' 103(l): 197-204PDF The generic name ''Phreatodrobia'' is derived from the Greek word " phreatos" which means ground water, as in phreatic, and from the suffix ''-drobia'' based on family name Hydrobiidae (where it was originally classified), which means "living in water". Species Species within the genus ''Phreatodrobia'' include: * '' Phreatodrobia conica'' Hershler & Longley, 1986 * '' Phreatodrobia coronae'' Hershler, 1987Hershler & Longley (1987). "Phreatodrobia coronae, a New Species of Cave Snail from Southwestern Texas". ''The Nautilus ''Nautilus'' is the fictional submarine belonging to ...

Edwards Aquifer
The Edwards Aquifer is one of the most prolific artesian aquifers in the world. Located on the eastern edge of the Edwards Plateau in the U.S. state of Texas, it is the source of drinking water for two million people, and is the primary water supply for agriculture and industry in the aquifer's region. Additionally, the Edwards Aquifer feeds the Comal River, Comal and San Marcos Springs, provides springflow for recreational and downstream uses in the Nueces River, Nueces, San Antonio River, San Antonio, Guadalupe River (Texas), Guadalupe, and San Marcos River, San Marcos river basins, and is home to several unique and endangered species. Basin characteristics Geography Located in South Central Texas, the Edwards Aquifer encompasses an area of approximately that extends into parts of 11 counties. The aquifer's boundaries begin at the groundwater divide in Kinney County, East of Brackettville, and extend Eastward through the San Antonio area and then Northeast where the aquif ...

Ground Water
Groundwater is the water present beneath Earth's surface in rock and soil pore spaces and in the fractures of rock formations. About 30 percent of all readily available fresh water in the world is groundwater. A unit of rock or an unconsolidated deposit is called an ''aquifer'' when it can yield a usable quantity of water. The depth at which soil pore spaces or fractures and voids in rock become completely saturated with water is called the ''water table''. Groundwater is recharged from the surface; it may discharge from the surface naturally at springs and seeps, and can form oases or wetlands. Groundwater is also often withdrawn for agricultural, municipal, and industrial use by constructing and operating extraction wells. The study of the distribution and movement of groundwater is ''hydrogeology'', also called groundwater hydrology. Typically, groundwater is thought of as water flowing through shallow aquifers, but, in the technical sense, it can also contain soil mois ...
