The past thirty years have seen the emergence of a growing desire worldwide
that positive actions be taken to restore and protect the environment from
the degrading effects of all forms of pollution — air, water, soil, and noise.
Since pollution is a direct or indirect consequence of waste, the seemingly idealistic
demand for “zero discharge” can be construed as an unrealistic demand
for zero waste. However, as long as waste continues to exist, we can only attempt
to abate the subsequent pollution by converting it to a less noxious form.
Three major questions usually arise when a particular type of pollution has
been identified: (1) How serious is the pollution? (2) Is the technology to abate
it available? and (3) Do the costs of abatement justify the degree of abatement
achieved? This book is one of the volumes of the Handbook of Environmental
Engineering series. The principal intention of this series is to help readers formulate
answers to the last two questions above.
