GROUNDWATER RECOVERY SYSTEM

摘要

A well and method for using the well for removing lighter than water pollutants (e.g. hydrocarbons and other organics) from a water table (14). The well includes a pneumatic pump (22) having an air exhaust port (48) to which a vacuum hose is attached for applying a vacuum to the pump chamber (44) to enable fluids to be drawn into the pump chamber (44) without regard to the hydrostatic head and at a rate sufficient to provide a drawdown of the water table (14) to enable capture of organic compounds present as a floating layer (16) on the water table (14).
