Future scientists, engineers, public health workers face challenges which were predicted, but certainly not expected to emerge this soon and to the magnitude presently occurring. The problems and projected solutions in this book cover a broad spectrum of issues including industrial and domestic solid wastes, air pollution and associated global warming, noise pollution and safety. Many engineering elements go into developing solutions to these problems including the need for additional detailed mapping and surveying, developing improved waste water treatment, including the development of more eco-friendly process and importance on conservation. Issues such as environmental assessments now play a most important role in practically all proposed developments. Old landfills are being mined for fuel, new landfills are designed to prevent waste materials from migrating to groundwater and new approaches to waste incineration focus on energy recovery and conversion of waste materials into usable materials. This text should help engineers and scientists meet the environmental challenges.
