Abstract:
1. A process for preventing the generally lateral, subterranean migration of fresh water beyond an established perimeter and routing of said fresh water comprising: determining the subterranean migration of fresh water by use of computer aided modeling of the terrain in combination with a field soil analysis to determine flows base on hydrostatic pressure; mapping soil permeability as a function of depth to quantify leakage losses due to soil layer consistency; calculating an insertion depth based on said hydrostatic pressure and said soil layer consistency for positioning of a non-permeable barrier that allows for the maximum interception of said subterranean migration of the fresh water; making an excavation to said insertion depth to accommodate said non-permeable barrier for maximum interception of the fresh water and allowing for a predetermined leakage loss; inserting said non-permeable barrier into said excavation; forming a slurry wall from a soil and bentonite mixture having a permeability rate of about 1.times.10.sup.−6 cm/sec, said slurry wall maintaining said non-permeable barrier in position; wherein said barrier wall intersects the flow path of subterranean migration of the fresh water and to route the fresh water to enhance containment said predetermined leakage loss reducing hydraulic pressure said barrier and said slurry wall.
