ENCYCLOPEDIA OF ENVIRONMENTAL SCIENCE AND ENGINEERING FULL BOOK PDF DOWNLOAD.
The editors were honored to have had the foreword to the first four editions written by the eminent thinker and
renowned environmental engineer, the late Dr. Abel Wolman. His insights through the decades proved to be accu-
rate and his overview is shared in this fifth edition as inspiration to innovators in the coming decades and in
memory of his distinguished contributions to the environmental field.
The 1980s appear in a world dominated by change at an unprecedented pace. Familiar and new problems tumble
over each other and are communicated globally by the second, instead of by the month. Scientific and technologic
choices are spawned day by day, while search for innovation is stimulated anew by government, universities, and
private industry.
Practitioners are startled by these events and try to keep apace with society’s demands by pressing for relevant
research, implementation of findings, and translating their significance to the public they serve. It is within this
challenging setting that a fifth edition of the Encyclopedia of Environmental Science and Engineering is born. Its
content is intended to register the striking characteristics of the changes we note to eliminate the already obsolete
and to expose the new on the horizon.
In the turbulence of the sixties and seventies, policies, plans, solutions, and regulations flowed without inter-
ruption from legislative and executive halls. The eighties might appropriately be devoted to post-audit stock-
taking and reorientation of both policy and action. Clarification of purpose in confrontation of the problems of the
environment is overdue. Validation of our efforts, over the last two decades, should provide an arena of productiv-
ity for science and engineering to guide us through the coming decades.
As manpower and money are always in short supply, even in so-called rich countries, they must be husbanded.
How to use them with maximum competence and logic, minimum risk, and least cost is a continuing obligation in
the protection and control of the biosphere.
We must extricate ourselves from adversarial combat in a world of negativism and move to an orderly identifi-
cation of what we know and away from the hysterical search for a doubtful Utopia. The authors in this fifth edition
continue the pursuit of new knowledge, calculated to bring new fruits of health, safety, and comfort to man and his
environs. The charms, as well as the subtle hazards, of the terms “conservation, preservation, and ecology” need to
be crystallized so that the public and their decision-makers practice this complex art with clearer conception and
perception than is apparent in recent bitter confrontations.
