Process for removing contaminants and apparatus therefor

A borehole is provided in the contaminated area a perforated riser pipe 44 is placed in the borehole a vacuum extraction pipe 30 with an opening arranged inside of the perforated riser pipe 44 is instaled within the perforated riser pipe 44 and a packing 61 is instaled in a portion of the annular space between the vacuum extraction pipe and the perforated riser pipe 44. And gases and liquid are introduced from the subsurface to the packing 61 by applying a vacuum to the vacuum extraction pipe 30 and the gases and the liquid are transported to the surface as a common stream and a stream which is primarily liquid and a stream which is primarily gaseous are formed and contaminants are removed from at least one of the liquid stream and the gaseous stream.
