The saline portion of the edwards aquifer s aline edwards aquifer has often b een mentioned as a source of water for desalination or a quifer s torage and r ecovery asr.However, because of.
Saltwater intrusion has occurred to some degree in many of the coastal aquifers of the united states.Since saltwater cannot be used to irrigate crops or be consumed by people, saltwater intrusion can be very problematic to coastal communities that rely on fresh groundwater supplies for the livelihood.

Saline intrusions into coastal groundwater via aquifer penetration have become a major concern 1 because it is the commonest source of pollution to groundwater.The extent of saltwater intrusions into groundwater is dependent on several natural and anthropogenic factors the nature of the aquifer and its natural recharge rates.
The map, which is derived from the ground water atlas of the united states, indicates the areal extent of the uppermost principal aquifers on a national scale.In this map, a principal aquifer is defined as a regionally extensive aquifer or aquifer system that has the potential to be used as a.

The floridan aquifer system, composed of the upper and lower floridan aquifers, is a sequence of paleogene carbonate rock which spans an area of about 100,000 square miles 260,000 km 2 in the southeastern united states.It underlies the entire state of florida and parts of alabama, georgia, mississippi, and south carolina.The floridan aquifer system is one of the worlds most productive.
Population growth and changing climate continue to impact on the availability of natural resources.Urbanization of vulnerable coastal margins can place serious demands on shallow groundwater.Here, groundwater management requires definition of coastal hydrogeology, particularly the seawater interface.Electrical resistivity imaging eri appears to be ideally suited for this purpose.
What is an aquifer an aquifer is a geological formation, composed of granular sediments or fractured rock, which contains sufficient saturated permeable material to yield significant quantities of water to wells and springs.How is groundwater contaminated groundwater contamination is linked to deficient practices and faulty infrastructures.
This study was aimed at mapping the subsurface extent of saline water intrusions into aquifers at the eastern part of dahomey basin, nigeria.The study adopted geoelectric sounding methods.108 vertical electrical soundings ves and 9 induced polarization soundings ips data were acquired using schlumberger array technique.Three aquifer units were delineated across the study area.

As a new sink of co2 permanent storage, the depleted shale reservoir is very promising compared to the deep saline aquifer.To provide a greater understanding of the benefits of co2 storage in a shale reservoir, a comparative study is conducted by establishing the full-mechanism model, including the hydrodynamic trapping, adsorption trapping, residual trapping, solubility trapping as.
The worlds first subsurface co 2 sequestration operation is currently running at the sleipner field in the central north sea.Here, co 2 extracted from the natural gas produced at sleipner, is being injected into the mio-pliocene utsira sand, a subsurface saline sandstone aquifer, at a depth of about 1000 m below sea level.The injected co.
These problem soils range from a slightly saline soil condition which reduces crop growth to extensive areas where cultivation is almost impossible.Problems relating to the origin and management of dryland saline soils have been discussed at several meetings in the recent past anonymous 1976, 1978 holmes and talsma 1981.5.1 mode of formation.

The ultimate fate of cosub 2 injected into saline aquifers for environmental isolation is governed by three interdependent yet conceptually distinct processes cosub 2 migration as a buoyant immiscible fluid phase, direct chemical interaction of this rising plume with ambient saline waters, and its indirect chemical interaction with aquifer.
Underground saline aquifers are widely used for the disposal and storage of waste and unwanted fluids.Due to their large capacity, deep saline aquifers and depleted oil reservoirs are now the main candidates for geological storage of co 2 as a means to cut anthropogenic co 2 emissions.There are two options for carbon dioxide sequestration in a deep saline aquifer in situ and ex situ.
