PREFACE
This book is meant to be an introductory text on the Fundamentals of Environmental Science
and Engineering. Today, knowledge of Environmental Science is essential for students as well
as practicing engineers and scientists of all disciplines. Here an attempt has been made to
provide precise and upta date infoIlllation on the fundamental aspects of Environmental Science
and Engineering without going much in-depth in to specific areas, so as to be useful for a
cross section of fields of study. Indian technical universities are making the study of
Environmental Science and Engineering mandatory for all courses and hence a 'comprehensive
textbook covering all domains of this field (including the policy aspects and management
practices) is the need of the hour.
The book adopts a simple narrative style keeping in mind both the knowledge requirements
and the examination needs of university students. The authors wish to profusely thank all those
who have supported them in the
