A method for storing hazardous materials within a pile by installing a drill casing a perforated casing section into a well installed in the pile, inserting a pipe or hose having an opening into the drill casing, aligning the opening of the pipe or hose with at least one perforated casing section, sealing the drill casing to isolate air or fluid flowing into or out of the drill casing so that the air or fluid only flows into or out of the drill casing through the at least one perforated casing section, pulling or pushing air or fluid through the pipe or hose at a pressure sufficient to open void spaces within the pile, and injecting hazardous materials through the pipe or hose at pressure sufficient to cause the hazardous materials to fill the void spaces.
