Abstract
A method for treating contaminants includes emitting plural streams of a fluid into a soil formation with the streams having different radii of influences in different directions. A directional microporous diffuser directionally emits microbubbles. Solenoid controlled valves control fluid or air distribution to inlets to provide directional control of bubble emanation.
