Abstract
A well and method for using the well for removing lighter than water pollutants (e.g. hydrocarbons and other organics) from a water table. The well includes a pneumatic pump having an air exhaust port to which a vacuum hose is attached for applying a vacuum to the pump chamber to enable fluids to be drawn into the pump chamber without regard to the hydrostatic head and at a rate sufficient to provide a drawdown of the water table to enable capture of organic compounds present as a floating layer on the water table.
