Abstract
A sampling device is provided for driving into the ground to sample fluids at a desired depth without requiring the drilling of a well. The sampling device utilizes a universal drive point device which is removably coupled to a tubular point holder. The drive point device includes an outer surface which extends along a drive cone between a lower end and an upper end along a longitudinal axis. The outer surface tapers radially outwardly from the lower end and is adapted for penetrating the ground to form a borehole. A stub extends outwardly along the longitudinal axis from the upper end of the drive cone. The stub is configured for insertion within a bottom end of the tubular point holder. The stub includes an axially elongated circumferential groove. An elongated annular seal is seated within the circumferential groove. The annular seal is adapted for frictionally coupling and sealing against an inner diameter within the bottom end of the tubular point holder. The annular seal is highly compressible and expandable to accommodate tubular point holders of different inner diameters.
