In Africa, groundwater is the major source of drinking water and its use for irrigation is forecast to increase substantially to combat growing food insecurity. Despite this, there is little quantitative information on groundwater resources in Africa, and groundwater storage is consequently omitted from assessments of freshwater by: An online introduction to the groundwater resources of 51 African countries, and a gateway to further information. Many of the country profiles have been co-authored by groundwater experts in Africa. Each profile includes new hydrogeological and supporting maps, and references and links to further online and printed information. In eastern Uttar Pradesh, Bihar, West Bengal and Orissa there is thick layer of marshy soil spread over the ground, hence they are most suitable for underground development because of lesser depth. The level of groundwater development is 6 per cent in Orissa, 19 per cent in Bihar, 24 per cent in West Bengal and 34 per cent in Western Uttar Pradesh. 4. Ground water dependent community. Based on the above criteria, artificial recharge to ground water in South and South west district needs to be given top priority so as to make the ground water resources sustainable and improve the quality which is deteriorating because of over-exploitation.
management of ground water resources should involve a combination of supply side and demand side measures depending on the regional setting. As far as ground water resource availability is concerned the share of alluvial areas covering Eastern Plain states of Bihar, Orissa (part), Eastern Uttar Pradesh and West Bengal and. Potential additional groundwater resources) because for this the data sets were considered to be outdated. All details of the digitization process are described in the project report. It describes the published paper maps and reports, from which the dataset was derived, the digital dataset, its formats and attribute data and highlights a number. To improve the borehole success rate in these terrains, and to develop groundwater resources in a sustainable manner, a multi-disciplinary approach is needed. This approach must incorporate: an understanding of the structural geology and its influence on the occurrence of groundwater so that target features can be identified;. The geology of Ghana is primarily very ancient crystalline basement rock, volcanic belts and sedimentary basins, affected by periods of igneous activity and two major orogeny mountain building events. Aside from modern sediments and some rocks formed within the past million years of the Phanerozoic Eon, along the coast, many of the rocks in Ghana formed close to one billion years ago or.
Uttar Pradesh is a part of the middle Indo-Gangetic plains and has been found to be severely affected by As contamination of groundwater, as established by several small-scale studies. 1. Introduction. The presence of arsenic in ground water has been reported from many parts of the world particularly in the Bengal delta and Bangladesh (Berg et al., ), China (Kinniburgh and Smedley, ), Vietnam (UNESCAP-UNICEF-WHO, ) and Nepal (Tandukar et al., ).Arsenic contamination in India is well documented (Datta and Kaul, , Garai et al., , . ground. Water in the aeration zone, usually temporary, is formed in periods of recharge and occurs near the surface in poorly permeable rocks (loams, clays). The close connection between groundwater and atmosphere is apparent throughout the aeration zone. Rain and snowmelt water percolates into the depth and recharge groundwater resources. There may be this issue in Maharashtra, but in Eastern Uttar Pradesh, Bihar and West Bengal, adequate rainfall and geology ensures that water tables are replenished regularly so such issues are.
