Environmental engineering is an engineering discipline concerned with the application of scientific and engineering principles to improve and maintain the quality of environment. While environmental science focuses on collecting and analyzing data as well as making hypothesis on the basis of this data, environmental engineering involves the application of this data for the production of outcomes which lead to reducing the impacts of development and population growth. The book studies, analyses and explains the most important concepts in environmental engineering and science. The topics included herein are of utmost significance and bound to provide incredible insights to readers. The book is a resource guide for experts as well as students.
