Abstract
A process and system for separating and removing volatile organic compounds (VOCs) from groundwater, where said groundwater is polluted by immiscible liquid floating on the water table and by solutes within the water. The process includes pumping the contaminated water through a separator and low pressure tank assembly, that separates silt, sand, and liquid VOCs from the water. The water is pumped through an air stripper to remove the dissolved volatiles from the water. The recovered liquid VOCs from the pressure tank are suitable for processing or reuse. The volatiles liberated from the water in the air stripper are released either to the atmosphere or routed to pollution abatement devices as required by environmental rules. The decontaminated water is released to a sewer system or to the environment.
