Technical expertise is important for my projects.   XDD is flexible, likable, and not expensive relative to the services they provide. Unlike some companies who do things the same way every time, XDD is very agile when confronted with changing site conditions.

Hydraulic Capture

Sometimes groundwater extraction and treatment (also known as pump and treat – P&T) makes the most sense for sites where:

  • Capital expenditures for other remedial technologies are significant relative to long-term operation and maintenance of an extraction system
  • Subsurface conditions are not amenable to other in situ remedial technologies

  • Sensitive receptors are located immediately downgradient of groundwater impacts
  • Regulations require hydraulic capture

As XDD is not invested in pushing a singular in-situ remedial technology, we have designed, installed, and operated a number of remedial systems involving hydraulic capture.  Tasks completed by XDD include:

  • Superfund level groundwater and fate and transport modeling
  • Well, conveyance, and equipment construction design and installation oversight
  • Value engineering and design calculations to meet discharge permitting requirements
  • Operation, maintenance, and monitoring services

Recent pump and treat systems designed and installed by XDD Environmental include:

  • Superfund groundwater extraction and treatment at a historic landfill in southern Vermont
  • State led hydraulic capture system in northern Indiana
