Innovative remedial techniques used at distressed brownfields in recent years include in situ thermal remediation, bioremediation and in situ oxidation.
Over the succeeding years, these targets were substantially exceeded, with the brownfield proportion reaching 80% by 2009, and average densities 43 dwellings per hectare.
Typical contaminants found on contaminated brownfield land include hydrocarbon spillages, solvents, pesticides, heavy metals such as lead (e.g., paints), tributyltins, and asbestos.
