    - In your opinion is the landfill tax (please tick);
      
      Too high. ( )
      
      Too low. ( )
      
      Just right. ( )
      
      Comments: ....................
      
      To date, the introduction of a landfill tax has (please tick);
      
      encouraged the use of alternative remedial methods to the traditional dig and dump and so decreased the amount of landfilling. ( )
      
      had little effect on the use of alternative remedial methods. ( )
      
      had no effect at all on your operations and activities ( )
      
      My research to date has shown that a wide range of innovative remediation technologies have been proven in the United States, the Netherlands and Germany. These have been offered within the UK recently, although these appear to be considered too expensive and so therefore are not commonly used.
      In your opinion what would raising landfill tax achieve? (Please tick);
      
      The use and development of more innovative remedial methods. ( )
      
      An increase in use of tried remedial methods in conjunction with dig and dump ( )
      
      Nothing. ( )

      List in order of priority, the factors which may be regarded as significant obstacles to using innovative in-situ remediation technologies, in the UK;
      
      insurance (liability). ( )
      
      financial backing. ( )
      
      UK conditions not easily comparable to those elsewhere. ( ) (will the new technologies be successful in the UK)?

      Other: ......................... ( )
      
      In-situ treatment can avoid the costs and nuisance associated with excavation and transport, and the long-term problem of maintaining landfill sites. Do you think that in-situ treatment should be encouraged when choosing a remedial method? (Please tick);
      
      Yes. ( )
