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.
Aggressive removal of dense non-aqueous liquid (DNAPL) phase tetrachloroethylene (PCE) and trichloroethylene (TCE) under and active manufacturing facility is the objective of an electrical resistance heating (ERH) system that was installed using horizontal drilling.
Bentonite-based drilling fluid is hydrated ex situ and yields prior to commencing directional drilling; and
bentonite is a component of the directional drilling mud system, not the sole component.
On Sept. 13th 2001, Kathy Sequino’s telephone rang. It was the New York Department of Transportation.
Horizontal Soil Vapor Extraction and Horizontal Air Sparge Well Case Study. Installation to remediated site closure.
Air sparging (AS) is a proven groundwater remediation technique that removes volatile organic compounds (VOCs) from groundwater.
Directional Technologies designed and installed 17 entry/exit horizontal remediation wells for bioamendment injection and 10 utility conduit crossings under the busy tracks in the rail yard.
Directional Technologies successfully overcame challenges while installing four horizontal air sparging wells at an Air Force facility in the southeastern United States
Directional Technologies designed and installed a radial horizontal well system of six blind horizontal wells, with over 200 feet total of horizontal screen.
