The invention is a system and a method for bioremediating hydrocarbon-contaminated groundwater. The method comprises contacting the hydrocarbon-contaminated groundwater with a source of microbial nutrients and then aerating the nutriated water with air or oxygen, the aeration being conducted under substantially bubble-free conditions.

[ What is claimed is:] [1.]1. A system for treatment of hydrocarbon-contaminated ground water comprising:an underground bioreactor having an inlet at a first end and an outlet at a second end;barrier means for diverting a plume of the hydrocarbon-contaminated groundwater into the inlet of the underground bioreactor;means for supplying microbial nutrients proximate the inlet of the bioreactor; andmeans for supplying substantially bubble-free oxygen or air to the bioreactor. [4.]4. A method for enhancing the biodegradation of hydrocarbon-contaminated water comprising:directing the hydrocarbon-contaminated water to flow through an in-ground bioreactor and in contact with a source of microbial nutrients therein while introducing oxygen or air into the water in the bioreactor, the nutrients being controlled release pellets dispersed over an inorganic mesh in the form of a spiral-wound bale, and the oxygen or air being introduced substantially bubble free, thereby enhancing the biodegradation of the hydrocarbon-contaminated water.
