The Centre is working on a sustainable plan to provide safe drinking water for all citizens in the light of a Supreme Court directive that all citizens must have access to the resource, said Dr Laxman Prasad, Advisor, Department of Science and Technology, New Delhi.
Central Ground Water Board (CGWB) organised two-day workshop on Water Management and Hydrochemistry in the auditorium of Wadia Institute of Himalayan Geology. The participating experts strongly recommended for proper rehabilitation of the areas of land degenerated by mining in the State.
<p>A three-dimensional mathematical model to simulate regional groundwater flow was used in the coastal area of Kanyakumari district in South Tamil Nadu. The study area is characterized by heavy rainfall, less extraction of groundwater for agricultural, industrial and drinking water supplies. </p>
The present study attempts to delineate aquifers in the piedmont zone of Himalayan foothill region in Pathri Rao watershed, district Haridwar, Uttarakhand, India by using integrated hydrogeologic and geophysical techniques. The geophysical techniques included vertical resistivity soundings, two-dimensional resistivity image profiling and electromagnetic surveys.
There is a need to analyse the rain water before recharging the ground water using rain water harvesting methods, said Marine and Coastal Survey Division Geological Survey of India DDG P V Sukumaran.
In India, small water reservoirs in the desert area are a part of a complex inter-linking natural resource management system. Traditional methods of water harvesting were employed by the local communities led by TBS to rejuvenate a local river, recharge the ground water and re-green a village. In Alwar district, 8600 small water harvesting talabs in 1086 villages have been built since 1985.
Recycling of water has assumed great importance worldwide due to water scarcity in urban areas. Use of fresh water for non potable secondary purposes will have huger burden on natural resources. Based on this objective, a water recycling plant was designed with tertiary treatment consisting of biological contractors for the South Western Railways, Bangalore.
This paper by CGWB on effective management of available ground water resources calls for an integrated approach, combining both supply side and demand side measures. Says that urgent action is needed to augment the ground water in the water stressed areas.
The groundwater is declining in majority of the areas of Delhi on account of overexploitation of the resources. The rate of decline is as high as 1.7 to 2 meters/year in some areas (South & South west Dist.). Thus seven out of nine districts of Delhi are categorized as overexploited with respect to dynamic groundwater resources.
