NEW DELHI: The two-day national conference and workshop on "Emerging Technology for Controlling Groundwater Pollution: Drinking Water Perspectives'' ended here on Friday recommending use of scientific methods involving modelling techniques and improved understanding of relations between contaminants. Other recommendations that emerged during the deliberations included use of Geographical Information System and watershed approach, developing and evaluating viability of emerging low cost water treatment technologies, in situ water treatment and pollution controlling techniques for groundwater at field scale and strengthening the involvement of academia and researchers. Suggesting use of artificial recharge techniques in different parts of the country, former Chairman of the Central Ground Water Board, D.K. Chadha, emphasised the need for focused research on groundwater estimation for the country. Contamination of groundwater resulting from landfill sites was another concern raised during the discussions. Speaking on the potential of groundwater contamination that might result from sanitary landfill facility at Bhatti Mines in the Capital, Dr. Keshari from IIT Delhi described how the pollutants would spread and contaminate groundwater in South Delhi. About 125 delegates participated in the conference. Fifty-odd technical papers were presented at six technical sessions covering groundwater problems and issues, environmental consequences of developmental activities, human health risk assessment, technologies for controlling groundwater pollution, groundwater quality monitoring, hydrogeological investigation, drinking water supply, water treatment technologies, groundwater chemistry and sustainability of groundwater resources. The two-day conference heard many eminent speakers including the Chairman of the Central Ground Water Board, Saleem Romani; Chief Executive Officer of Delhi Jal Board, Rakesh Mohan; Secretary-General of International Commission on Irrigation and Drainage, M. Gopal Krishnan; former Chairman of the Central Pollution Control Board, D.K. Biswas, and IIT professor, A.K. Gosain. The speakers shared their views and expressed the need to initiate direct action for water resources across the country. Organised by the Department of Civil Engineering, Indian Institute of Technology (IIT), Delhi, in association with the Search Foundation and Hinge Services, the conference was supported by Union Ministry of Environment and Forests.
