Abstract
An apparatus for decontamination contaminated groundwater in-situ by increasing the quantity of dissolved oxygen in the contaminated groundwater and generating reactive initiators to remediate the contaminated groundwater. The apparatus includes a submersible pump, an electrolytic cell, and a distribution chamber attached to an outlet of the cell. The distribution chamber is vertically oriented and longitudinally-extending from the outlet of the cell. As the groundwater flows across charging plates of the cell, some of the molecules break into their component parts of hydrogen gas and oxygen gas. A selected vertical length of the chamber provides a resident time for the fluid allowing a majority of the gaseous oxygen to transition to dissolved oxygen.
