The degradation of water bodies as a result of human activities is known as water pollution. It occurs when contaminants enter the natural environment. These contaminants can cause widespread disease and even death in humans through water-borne diseases. Water pollution can be caused by either point sources or non-point sources. The sources which have one recognizable reason of pollution are known as point sources. The non-point sources are relatively more diffused. The measurement of water pollution can be done by conducting chemical, physical or biological tests. Some of the various types of water pollution are groundwater pollution, surface water pollution and marine pollution. The topics included in this book on water pollution are of utmost significance and bound to provide incredible insights to readers. Different approaches, evaluations, methodologies and advanced studies on this field have been included in this book. The book is appropriate for students seeking detailed information in this area as well as for experts.

Water pollution refers to the contamination of water due to the release of substances into water bodies. The pollution sources that pollute water are broadly categorized into point sources and non-point sources. The contaminants that enter the water bodies from a single and identifiable source are referred to as point sources of water pollution. These include discharges from factory and sewage treatment plant. Non-point sources of water pollution are defined as the contamination caused by the cumulative effect of small amounts of contaminants that accumulate from a large area. The various contaminants that cause water pollution encompass pathogens and a wide spectrum of chemicals. Water pollution can be divided on the basis of its location into surface water pollution and groundwater pollution. Most of the topics introduced in this book cover new techniques to control water pollution. It consists of contributions made by international experts. This book will prove to be immensely beneficial to students and researchers in this field.
