Description
Essentials of Environmental Engineering is designed for use in an introductory university undergrad course. This book introduces environmental engineering as a profession applying science and math theories to describe and explore the relationship between environmental science and environmental engineering.
Environmental engineers work to sustain human existence by balancing human needs from impacts on the environment with the natural state of the environment. In the face of global pollution, diminishing natural resources, increased population growth (especially in disadvantaged countries), geopolitical warfare, global climate change (cyclical and/or human-caused), and other environmental problems, it is clear that we live in a world that is undergoing rapid ecological transformation. Because of these rapid changes, the role of environmental engineering has become increasingly prominent. Moreover, advances in technology have created a broad array of modern environmental issues. To mitigate these issues, we must capitalize on environmental protection and remediation opportunities presented by technology.
Essentials of Environmental Engineering addresses these very issues. It was written with the student in mind. Complex topics are explained in an easy-to understand format and style. Numerous examples are given and chapter review questions along with solutions are provided in the text.
