Directional Technologies designed and installed a horizontal environmental well system featuring variable slot sizes and spacing along the environmental well screen section.
Installation of three air sparge and one soil vapor extraction wells using horizontal directional drilling methods in the overburden material.
The IssueThe New Jersey Department of Environmental Protection (NJDEP) mandated groundwater and soil sampling under an active pharmaceutical company manufacturing building in order to address
Directional Technologies had a perfect solution for this contamination problem at a busy intersection: Install the wells blind, without exit points at the far side of the roadway.
Not a typical radius of influence for a horizontal well which is usually 80’ to 120’ perpendicular to each side of the well screen.
The Horizontal Remediation Well system effectively remediated the site within 18 months. The presentation takes you through the conceptual design and the horizontal well installation to the site closure.

Aggressive removal of dense non-aqueous phase liquid (DNAPL) tetrachloroethylene (PCE) and trichloroethylene (TCE) under an active manufacturing facility is the objective of an electrical resistance heating (ERH) system that was installed using horizontal drilling.
Directional Technologies designed/installed each air sparge well to deliver approximately 2 pounds per minute of oxygen to the subsurface, or a total of 4 pounds per minute.
