Risk management is an approach to decision making for historically
contaminated sites where the need for action, and the nature
of any possible actions, is decided on the basis of risk assessment.
Risk management is the key issue in contaminated land remediation.
This requires the assessment of the presumed contaminated
site. The orientation assessment provides that basis for
the statement of the preliminary risk, whereas the detailed
assessment identifies the contaminant(s) and the extent
of contamination. This is followed by the planning of the
contamination prevention actions. Finally, aftercare
ensures the regular control of the site, and if necessary,
provides the basis for further actions or defines the future
use of the site. During this process, continuous supervision
of activities is required, and priorities have to be decided
in each phase of the process.
