ABSTRACT
Despite the widespread use of Stabilisation/ Solidification (S/S) outside the UK since the 1950s, particularly in North America (US EPA 1986), (Conner 1998, Kirk 1996), there are few data pertaining to the field performance of S/S waste forms in service. In particular, there have been no co-ordinated field studies to verify the long-term effectiveness of S/S to treat waste for hazardous constituents. As a result of this omission from the literature, an international project, to extract S/S samples from remedial operations in the UK, USA and France has recently started. The project, Performance Assessment of Stabilised/Solidified Waste-Forms, or PASSiFy is expected to take 3 years to complete and involve 10 to 12 sites in these three countries.
