Abstract:
A method for the disposal of biosolids, the method comprising:a) providing a supply of biosolids; b) creating a slurry of the biosolids suitable for injecting; c) selecting an injection formation below a ground surface and separated from the ground surface by one or more pairs of alternating layers of high permeability and low permeability; d) injecting the biosolids slurry into the injection formation at a pressure sufficient to create and maintain fractures within the selected injection formation; e) allowing degradation of the injected biosolids slurry; and f) monitoring pressure in the one or more than one of the alternating layers of high permeability and low permeability above the injection formation during a time selected from the group consisting of before biosolids injection, during biosolids injection, after biosolids injection and a combination of before biosolids injection, during biosolids injection and after biosolids injection.
