ABSTRACT:
A method for selectively treating sections of soil which are more remote from a soil venting well than previously treated soil sections. Air is drawn through a first group of passageways in a well casing during treatment of a particular section of soil. Air is then prevented from passing through the first group of passageways, as by sealing them, and is drawn through a second lower group of passageways. By sequentially following these steps, different sections of soil located farther from the well and deeper than previously treated sections can be selectively treated.
