Text 16C Issues in soil remediation

Multifunctionality has proven very difficult to achieve in practice. About 50 per cent of the clean-upsoil does not meet the multifunctionaluity target and has to be used under additional constraints.
Achieving miltifunctionality may be hampered by the cost of the operations and by technical and feasibility constraints. Technology for soil remediation is developing very quickly with a shift from radical, hard solutions (such as excavate-pump-and-treat) to biological techniques which, for instance, exploit natural attenuation phenomena. However, the costs issues are still a mayor constraint to soil remediation. High costs have become both politically indefensible, and economically unfeasible. Facing sheer expenditures, companies have often applied await-and-seeattitude, delaying the operations as much as possible often exploiting the ambiguities of the guideline and the possibility of some discretionary interpretation of the law. The main issue raised by the private sector is that the multifunctionality objective systematically disregards efficiency and effectiveness considerations. Most companies do know what the future use of contaminated sites will be, and thus question the general principle that all sites should becleaned-upto the same extent. An industrial area may need less strict measures than a residential one. In addition, the application of soft, but long, remediation techniques may significantly cut costs, although

may delay the soil usage and leave many sites polluted for a considerable time.
Although the cost-relatedmatters are clear, the multifunctionality objective may also raise some environmental concerns. Scientists consider multifunctionality as thesoil-relatedinterpretation of sustainability. An implicit, and almost universal, assumption is that by cleaningup a polluted site (or rehabilitating any degraded area) there is a net environmental benefit. Growing evidence has been provided that suggests that this assumption should be challenged and that the overall environmental balance of remediation may not be always positive. By considering the full cycle of the remediation process, it can be recognized that the process requires the use of natural resources like energy and clean water, and may result into a transfer of pollution to other environments, for instance by creating air pollution, water pollution and waste. The soil remediation thus raises two types of environmental concerns:
1.A local, site specific concern, related to the need of reducing contamination below some safe level. This is clearly the positive site of the coin, in the sense that soil remediation provides a net local benefit.
2.A regional or even global concern, related to the need of minimizing the use of scarce resources during the operations and the spread and transfer of pollution to other environments. These factors are the negative side of the remediation and cannot be disregarded in computing the full environmental balance of remediation.
