Abstract:
A system for catalytic destruction of groundwater contaminants, comprising:a well-bore extending through a water-bearing zone and at least into a contaminated water-bearing zone, a well screen mounted in the well bore and within each of said water-bearing zones, a pump mounted in said contaminated water-bearing zone, a pneumatic packer in said well-bore located intermediate said water-bearing zones, a hydrogen source operatively connected to said pump to receive contaminated water, at least one catalyst column connected to said hydrogen source to receive contaminated water and hydrogen, said at least one catalyst column being constructed to at least reduce halogenated solvents in the contaminated water to a harmless species, and said at least one catalyst column being connected to said well-bore such that effluent from said at least one catalyst column is directed into said well-bore and into said water-bearing zone.
