Abstract
A method and system for removing free phrase product from the surface of a subterranean body of water includes a plurality of extraction sites. The extraction sites extend below ground and intersect the free product. Each of the plurality of extraction sites is in communication with a vacuum supply which provides suction to remove free product from the surface of the groundwater.
