Abstract
A controlled containment barrier system is provided that can prevent the migration of dissolved phased contaminants in water systems. The system includes sheet piling installed in a body of water, the sheet piling having valves disposed at various vertical elevations on the sheet piling panels that allow the discharge of water at various strata in the body of water through the barrier system.
Claims21
A controlled containment barrier system for a body of water disposed on top of a permeable layer of soil, the permeable layer disposed on an impermeable layer of soil, the system comprising:
- a) a plurality of barrier panels configured to be placed in a side by side configuration across the body of water wherein a lower edge of the panels is further configured to be inserted through the permeable layer to the impermeable layer;
- and
- b) at least one valve mechanism disposed on at least one of the plurality of barrier panels, the at least one valve mechanism configured to operated from a closed position, wherein water is prevented from flowing through the barrier system, to an open position, wherein water can flow through the barrier system.
An improved controlled containment barrier system for a body of water disposed on top of a permeable layer of soil, the permeable layer disposed on an impermeable layer of soil, the system comprising a plurality of barrier panels configured to be placed in a side by side configuration across the body of water wherein a lower edge of the panels is further configured to be inserted through the permeable layer to the impermeable layer, the improvement comprising:
- at least one valve mechanism disposed on at least one of the panels, the at least one valve mechanism configured to operated from a closed position, wherein water is prevented from flowing through the barrier system, to an open position, wherein water can flow through the barrier system.
A method for allowing uncontaminated water to flow through a controlled containment barrier system for a body of water disposed on top of a permeable layer of soil, the permeable layer disposed on an impermeable layer of soil, the method comprising the steps of:
- a) providing the controlled containment barrier system, the system comprising:
- i) a plurality of barrier panels configured to be placed in a side by side configuration across the body of water wherein a lower edge of the panels is further configured to be inserted through the permeable layer to the impermeable layer, and
- ii) at least one valve mechanism disposed on at least one of the plurality of barrier panels, the at least one valve mechanism configured to operated from a closed position, wherein water is prevented from flowing through the barrier system, to an open position, wherein water can flow through the barrier system;
- b) closing at least one of the valve mechanisms disposed at a first elevation substantially horizontally adjacent to a first strata of water disposed in the body of water, the first strata of water further comprising contaminated water;
- and
- c) opening at least one of the valve mechanisms disposed at a second elevation substantially horizontally adjacent to a second strata of water disposed in the body of water, the second strata of water further comprising the uncontaminated water.
