Insertion of Reactive Material for Treating Groundwater

An improved method of inserting reactive material in the ground for treating groundwater contaminated with chlorinated solvents has been devised. An older method involves the removal of a significant portion of soil overlying the treatment volume, and consequently the expensive off-site disposal of the large amount of removed soil (some or all of which is contaminated). In the improved method, only a relatively small amount of soil need be removed.
