Zusammenfassung:	A composite bioreactor and a method of using same is described. The bioreactor (10) comprises a combination of a sulphur oxidising bacteria (SOB) bioreactor (12) directly on top of a sulphate reducing bacteria (SRB) bioreactor (14); the SOB bioreactor (12) comprising a heap of said soil to be remediated and having suitable microorganisms therein to react with and degrade contained contaminants; said SRB bioreactor comprising trough means (18) having support means to support said soil heap associated with an opening thereof, said support means having a permeable membrane (16) associated therewith to allow passage of liquid but substantially no soil and sulphur reducing bacteria within said trough means (18); and liquid and nutrient supply means to promote growth of said sulphur oxidising bacteria and said sulphate reducing bacteria within said composite bioreactor.
