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