ABSTRACT:
The invention comprises a method for making an underground barrier for hazardous leachate that includes digging a trench under biodegradable slurry adjacent a contaminated area, placing a liquid impervious membrane on one side of the trench and securing it by an impervious plug of material lining the bottom of the trench adjacent the membrane's lower end. A drain pipe and risers are positioned in the slurry into which filter gravel is subsequently added.
