The ORS Probe / Pump is used to assist in the recovery of hydrocarbons from ground water. It automatically pumps water from under the oil / water interface so that a cone of depression is created. This increases the flow of surrounding water and pollutants into the recovery well, permitting more rapid clean-up of the ground water. The probe is designed to maintain the level of the recovery well at a predetermined distance below the surrounding water table. The probe will also shut the pump off automatically when hydrocarbons come near the pump intake. This feature prevents inadvertent removal of the hazardous materials. As the pollutants flow into the recovery well the Scavenger separates them out and automatically pumps them to the surface. (The Scavenger is a separate oil / water separation system not included with this pump).

Oil Recovery Systems was in business from the mid-1970s into the 1980s. They manufactured oil / water separation equipment. It spun off a division called Groundwater Technology in 1989, which is a firm that specializes in in-situ site remediation. It is now based in the Netherlands.
