Abstract
A tall cylindrical silicone rubber gas permeable tube is adapted to fit in an injection well at least partly below the water table for the bioremediation of organic contaminants and to contain pressurized oxygen and/or other gases supportive of the anaerobic micro-organism activity. The gases slowly diffuse through the bladder at rates that permit their full utilization by dissolution in the underground water.
