Low permeability cutoff walls can be used to control subsurface contamination and enhance the effectiveness of site remediation techniques. The Waterloo Barrier{trademark} (patents pending) is a steel sheet piling that incorporates a cavity within the interlocking joint between piles. The cavity is flushed clean and sealed after the piles have been installed in the ground to form a vertical cutoff wall. Bulk hydraulic conductivities of 10{sup {minus}8} to 10{sup {minus}10} cm/s have been demonstrated at field installations. Recent case histories are presented in which the Waterloo Barrier{trademark} is used as a component in the control and remediation of contaminated sites. At an abandoned mine site, groundwater containing elevated values of zinc and arsenic has migrated from the tailings impoundment to the adjacent lake. A municipal landfill site in a residential neighborhood is generating methane gas which has been detected in the basements of nearby homes. A cutoff wall constructed at the property line was designed to control off-site migration and improve the efficiency of a new, active gas collection system. The barrier has also been used at several commercial sites for control of flow of contaminated groundwater and for providing isolation and containment of subsurface sources of contaminants. Source isolation of DNAPLs at an industrial plant has been achieved with an enclosure cut-off wall keyed to an aquitard.
