A system and method for removing volatile organic compounds (VOCs) from groundwater. A compressor (18) injects gas into a well (10) through a gas line (16) to cause rising bubbles and a water flow toward and up the well (10). A water and bubble mixture (20) flows upward in an annular space (21). Water flows to an unsaturated zone (24) through a series of drains (25). A deflection plate (30) helps guide vapor to an extraction line (33) which ultimately leads to a vapor treatment device (34).
