What is Environmental Engineering?
  
It is the practical implementation of engineering solutions to environmental problems. Environmental Engineering deals with the minimization of waste generation, with the reduction of energy use, with the reduction of natural resources use, with the provision of safe drinking water, with the control of air and water pollution, with the remediation of polluted sites, etc, while providing at the same the development that the community requires. It also deals with the development of new and improved means to protect the environment.

Like most engineers, environmental engineers must have a strong background in mathematics, physics, and chemistry. They learn engineering problem-solving and how to work in teams to accomplish goals. They develop the ability to apply scientific principles as part of making engineering decisions. Environmental engineers are skilled in analysis and design, and they apply their knowledge to protect the environment and human health.
