An apparatus (10) for decontamination of 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 (330), an electrolytic cell (334), and a distribution chamber (336) 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.

Appareil (10) de décontamination d'eaux souterraines contaminées in situ, par augmentation de la quantité d'oxygène dissous dans l'eau souterraine contaminée et génération d'initiateurs réactifs pour remédier à l'eau souterraine contaminée. L'appareil comprend une pompe submersible (330), une cellule électrolytique (334) et une chambre de distribution (336) reliée à une sortie de la cellule. La chambre de distribution est orientée verticalement et s'étend longitudinalement à partir de la sortie de la cellule. Du fait que l'eau souterraine s'écoule à travers les plaques de chargement de la cellule, un certain nombre de molécules se scindent en leurs constituants hydrogène gazeux et oxygène gazeux. Une longueur verticale sélectionnée de la chambre procure un temps de séjour pour le fluide, ce qui permet que la majeure partie de l'oxygène gazeux passe à l'état d'oxygène dissous.
