Pollution is undesirable state of the natural environment being contaminated with harmful substances as a consequence of human activities so that the environment becomes harmful or unfit for living things; especially applicable to the contamination of soil, water, or the atmosphere by the discharge of harmful substances. In addition to the harm to living beings, both present or future and known or unknown, pollution cleanup and surveillance are enormous financial drains of the economies of the world. This book focuses on issues and developments critical for the field.

Regional Approaches to Water Pollution in the Environment integrates knowledge and experience on pollution problems related to industrial, agricultural and municipal activities and former military sites, with special emphasis on the Black Triangle: the region situated at the borders between North Bohemia, Polish Lower Silesia and South Saxony. Here, some five million inhabitants live in an area of brown coal basins having the highest emissions of sulphuric and nitrogen emission in the whole of Europe. The large-scale damage in this region is due to obsolete technology and insufficient equipment for monitoring emissions. Health effects are severe, and controlling the pollution can only be done at high cost. There is thus a need to exchange knowledge and experience on methods for evaluating the expected effects of measures and purification techniques to remedy ground and surface water pollution.

Pollution is undesirable state of the natural environment being contaminated with harmful substances as a consequence of human activities so that the environment becomes harmful or unfit for living things; especially applicable to the contamination of soil, water, or the atmosphere by the discharge of harmful substances. In addition to the harm, either present or future and known or unknown, to living beings, pollution cleanup and surveillance are enormous financial drains of the economies of the world. This book gathers leading research from throughout the world dealing with water pollution.

Public agencies and industry will probably spend tens of billions of dollars on new water pollution abatement facilities in the next few decades. Added billions will be spent for the operation of new and existing facilities. How can physical science research reduce the cost of achieving objectives? And how can social science research make sure that the right objectives are being efficiently pursued? This title, first published in 1962, is directed to the orientation of the research effort, and the tool used for this purpose is an economic framework. This book will be of interest to students of economics and environmental studies.

Goethe said- Everything originated in water, and everything is sustained by water . Really with its multidimensional uses, water is one of the most precious gifts of nature without which no life could survive. The maximum part of the earth is covered with water but unfortunately we have only 3% of it in the form of freshwater, out of which 2% is in the form of glaciers and mountain ice thus only 1% of the total is on disposal for various requirements. The water is more enough if it is used and managed properly but due to our mismanagement and non-awareness, the whole world is facing teething crisis of water shortage as well as water pollution. Not only this, the waterbodies are now-a-days treated as dustbin. Man has miserably failed to realize his unabated interference in the natural recycling of essential elements, which have posed a serious threat to his own existence. The aim of this book is to provide a wide-ranging and authoritative coverage or water pollution, which is fundamental to our understanding and appreciation of the nature of aquatic environment. The book will be very much helpful for students, research scholars, Professors, scientists and policy makers in order to provide a sufficient depth of the subject to satisfy the needs at a level which will be comprehensive and interesting.
