ABSTRACT:
A device and method are set forth to obtain a ground water sample. The device includes a drive cone adapted to penetrate the ground and a main body having a closed sample chamber. The main body is movable relative to the cone between the first position where the body and cone abut for inserting the device into the ground and a second position where the cone is frictionally restrained by the ground and the body is withdrawn upwardly relative to the cone to expose a sampling tube. The tube including a plurality of openings to receive ground water into the chamber. After receiving the sample, the device is retrieved from the ground.
