ABSTRACT
The process of cleaning and restoring contaminated soil and water, with the possibility of associated air contamination, is just beginning to be understood as a complex and costly undertaking. The regulatory steps themselves are lengthy and many months may be consumed before remedial action can actually begin. Gathering sufficient data to characterize the extent of the contamination fully and finding accurate cost figures on which to base the feasibility studies and decisions have been difficult. However, as more sites are addressed, more remedial techniques are commercialized, and more case studies and other documentation are published, the task of remediation is becoming more manageable and systematic.
