Directional drilling has been used for a variety of purposes, including utilities, dewatering, and remedial activities. Using this method for site cleanup versus traditional vertical extraction wells needs to be considered based upon today's remedial challenges. Traditionally, it has been stated that a single horizontal well can substitute for up to 11 vertical wells. This “rule” is arbitrary, since length and depth of the plume, surface access, and hydrogeological conditions must be considered. A better way to evaluate the cost‐benefit of a horizontal versus vertical well system is a predicted zone of influence using a mathematical and hydrogeological approach, as described herein.
