ABSTRACT:
A subterranean pump of compact design can be inserted into boreholes commonly used for exploratory drill holes to observe subterranean contaminants. The pump operates at the water-oil interface so as to draw off contaminating oil while avoiding the unnecessary pumping of water which would deplete the capacity of the pump. Preferably, the subterranean pump is a jet pump (ejector or educator) which operates on fluids pumped back down-hole by an above ground auxiliary pump. The down-hole pump is maintained at the water-oil interface by floats or other sensors which detect the water-oil interface and operate an electrical hoist or other lifting device to raise and lower the pump in the borehole.
