Over a century of intensive industrial and agricultural activity has left a spate of contaminated land areas, now being identified as possible sites for re-development. Increasingly, design professionals are facing the challenges of treating contaminated soils. This note outlines the legal issues of remediation and who is responsible for the clean-up costs. It also explores various options of treating contaminated sites and how these areas can be safely reused.
