Abstract:
A method of treating a contaminant in groundwater from an aquifer, comprising the steps of:a. identifying a contaminant to be treated;b. preparing a hole through soil layers in the earth to expose an aquifer having a contaminated groundwater therein;c. planting a tree with a root system in said hole in soil so as to develop a treatment area defined by the hydraulic gradient established by the root system, the hydraulic gradient being dependent upon the tree's use of water;d. selecting a treatment material, structure or device in addition to the soil to assist in the treatment of the identified contaminant in the aquifer; ande. arranging the treatment material, structure or device in the treatment area such that water pumped to the root system by the hydraulic gradient of the tree root system is exposed to the treatment material, structure or device before the water is used by the tree via its root system, whereby the treatment material, structure or device treats the identified contaminant from the aquifer.
