Passive NAPL Barrier Design and Construction
In 2006, a “passive” non-aqueous phase liquid (NAPL) barrier was installed at New York State Electric & Gas Corporation’s (NYSEG’s) Court Street Former MGP Site

Construction and In-Situ Hydraulic Conductivity Evaluation of a Deep Soil-Cement-Bentonite Cutoff Wall
This paper presents a case study of a deep soil-cement-bentonite (SCB) slurry trench cutoff wall constructed outside of Smithland, KY in 2010. Installed to a
INSTALLATION OF A SOIL-BENTONITE CUTOFF WALL 4 THROUGH AN ABANDONED COAL MINE
The site is a 72,846 square meter (18-acre) abandoned strip mine located in Western Pennsylvania used for municipal and industrial waste disposal until the mid-1970’s.
Time-Dependent Strength Behavior of Soil-Bentonite Slurry Wall Backfill
Soil-bentonite (SB) slurry trench cutoff walls have been used for over 30 years as subsurface vertical barriers to control ground water flow and contaminant transport.
DESIGN AND CONSTRUCTION CONSIDERATIONS FOR THE USE OF SLURRY WALLS TO CONSTRUCT WATER RESERVOIRS IN THE DENVER FORMATION
Continued population growth combined with limited water resources in the Denver area has resulted in the conversion of a number of mined out gravel pits
Vertical groundwater barriers for contaminated site reclamation
Groundwater barriers are used to maintain separation between contaminated and non-contaminated groundwater regimes. They are often used as part of site reclamation works. In this
Soil Bentonite Cut-off Walls for Confinement of Existing Landfills
The construction of a soil-bentonite (SB) barrier wall in 2004 to confine a landfill at Tempe Tip adjacent to Sydney Airport was the first of
Soil Bentonite Slurry Trench Cutoff Walls: History, Design, and Construction Practices
Slurry trench cutoff walls have been widely used for over 70 years to control groundwater flow, seepage through dams and levees, and contaminant transport. In
DESIGN AND SPECIFICATION CONSIDERATIONS FOR ENVIRONMENTAL CUTOFF WALLS
Vertical cutoff, or barrier, walls are an integral part of environmental site remediation efforts. Vertical barriers are commonly deployed to limit the influx of clean
Cone Penetration and Dilatometer Tests to Evaluate Stresses in a Soil-Bentonite Slurry Trench Cutoff Wall
Soil bentonite (SB) slurry trench cutoff walls have been widely used for over 40 years to control ground water flow, seepage through dams and levees,
