Abstract:
A method for treating contaminated groundwater comprising:selecting an intake point for groundwater, said intake point in hydraulic communication with a source of contaminated groundwater having a natural flow rate, said intake point having a first hydraulic head pressure;selecting a discharge point for said groundwater for discharging said groundwater, said discharge point having a second hydraulic head pressure lower than said first hydraulic head pressure, wherein said intake point is located within a first aquifer and said discharge point is located at a point selected from the group consisting of a second aquifer, a vadose zone, a surface water body, and a ground surface;providing a conduit between said intake point and said discharge point, said conduit forming a passive hydraulic communication with said intake point and said discharge point, said conduit having a relatively low hydraulic pressure head loss therethrough;establishing a passive flow of groundwater between said intake point and said discharge point through said conduit, said passive flow having a passive flow rate greater than said natural flow rate;providing a treatment media within said passive hydraulic communication, whereby said contaminated water flows through said treatment media prior to said discharging.
