The present book entitled "Water Pollution and its Recent Challenges" embodies pioneer researches delivered and discussed during the two-day UGC sponsored National Seminar organized by the University Department of Chemistry, S.K.M. University, Dumka, Jharkhand in April 2011, convened by Dr. Hashmat Ali, on the most burning issue of the day viz. Water Pollution. The seminar was attended by a galaxy of Scientists and Researchers from different parts of India. By far the most serious and ominous problem the world is facing today is the problem of water pollution. In spite of adopting various measures in existence so far to check the pollution, the situation is worsening in its complexity day by day due to rapid industrialization, urbanization and exponential growth in population. Moreover, reckless exploitation of water resources to meet the growing demands without paying heed towards sustainability factors has deteriorated the situation furthermore. In the context of such a critical situation, the book, I am sure, will be proved a boon for the speedy control of the continuously deteriorating situation of the problem as the topics contained in the book emphasize mainly over the remedial measures to combat, mitigate and check the pollution. For, some of the most significant deliberations after peer review have been selected to design the book in hand a peerless treatise. The editor realizing the utility and the standard of the book hopes that it would be of immense benefit to Students, Research Scholars, Teachers, Industrialists, NGOs, Policy makers and Scientists working in the field of Water Pollution.
