Options appraisal

Options Appraisal and the Standard of Remediation. In a regime driven only by arbitrary exceedance of limit values for particular contaminants, the question of standards for remediation would be conceptually quite simple. They could take the form of numerical target values for the same contaminants, set either at or below the triggering limit values. Leaving aside the difficulties of setting comprehensive limit values for all substances in all circumstances, what this approach also inevitably implies is that the only permissible approaches to remediation would be those that acted directly on the contaminants themselves.
