This book documents the most extensive study ever on the use of deep sea tailing placement at the Island Copper Mine on Canada's Vancouver Island. The study examined all aspects of this innovative program which utilized 400 million tons of tailing solids, beginning with its initial implementation in 1971 to five years after the mine's closure in 1995. Coverage includes placement program, engineering, chemical, biological, cost savings and environmental considerations. Includes 8 color pages.

Environments at Risk is designed as an introductory text and uses case histories of environmental impact assessment to raise issues important in controlling environmental problems. This approach is novel as is the concentration on assessment procedures. In his twenty years of involvement with such cases, Professor Ellis developed his own method of approach for auditing environmental impact assessments, a method which will help readers appraise similar cases in which they are involved, either as concerned citizen, environmental managers or assessors.
