ABSTRACT:
A method and apparatus for safely disposing hazardous waste in a borehole extending through a seal for a subsurface geopressured formation wherein sealed elongated containers filled with hazardous waste are lowered in the borehole to be positioned within a geopressured formation where the containers are encased in the borehole. In an alternative embodiment, hazardous waste is disposed in the borehole by pressuring the liquid waste and injecting the waste through perforations in a borehole casing directly into the pores of a geopressured formation. The pressurized liquid fractures the geopressure formation and upon release of the pressure on the waste liquid the waste is trapped in the geopressured formation. The seal of the geopressure formation is then restored for providing safe disposal.
