- Summary:
- Remediation of subsurface contamination is an up-to-date subject, due to the high number of contaminated sites in all developed countries. Risk assessment for long term exposure to humans is the approach most applied world-wide to identify contaminated sites and the remediation target limits. This book discusses research in this field.
