Today, there is much discussion about the dangers of water contamination to human health. Numerous environmental studies and projects are undertaken and accomplished every year. Despite this, most developing countries continue to struggle with the inefficient administration of their water supplies. The problem of contaminated water and the method of purifying it are both extremely challenging, and much of the research done on the topic is probably not up to the mark to cope with the current environmental issues. Henceforth, appropriate methods need to be developed and established to improve water quality. Through this book, the authors aim to provide a framework for understanding the causes, pollutants, and potential remediation for water contamination. The text provides up-to-date reviews of the latest research and practises for removing contaminants from water through green methods.
