Abstract

The invention provides a novel apparatus and method for removing liquid contaminant from a well to decontaminate a contaminated aquifer. The apparatus includes a pump capable of moving water and contaminant from below ground surface to a location above ground surface, a motor connected to drive the pump and means connected to power the motor. A water and contaminant inlet are located between the pump and the motor to accept inward flow of water and contaminant to the pump. An outlet pipe connects to the pump and extends above ground surface. A sleeve surrounds the inlet and connects between the inlet and the motor and has an opening to receive water and contaminant. The sleeve is sized to slide in and out of the well and is larger than the outlet pipe. The sleeve creates an annular space around the outlet pipe to permit passage of water and contaminant from the open end to the inlet.
