Many traditional methods of decontamination use chemicals which are inherently harmful and can be direct environmental hazards. These methods may generate large volumes of mixed waste and high disposal costs. Sandblasting grit disposal costs have dramatically increased. Also, the additional volume of contaminated waste generated by sandblasting impacts the facilities disposal quotas. Water blasting now requires expensive procedures. State and federal governments are developing regulations that are restricting the use of these methods. Therefore, alternative technologies are becoming increasingly important.
