<p>The invention provides an apparatus and method for taking samples of soil and other materials in an efficient manner as well as for maintaining a high level of integrity of the samples. Using a wire line and a release and retrieve assembly (14), the sampling tube (10) is lowered into an auger (28) that has been bored into the ground to the desired depth. Once lowered to the bottom of the auger (28), the sampling tube (10) is locked into place and the release and retrieve assembly (14) is removed from the auger. A portion (76) of the sampling tube (10) extends beyond the drill bit (16). As the auger is drilled further into the ground, the sampling tube (10) is filled with soil or whatever material is present, without such soil or other material having been disturbed by the drill bit (16). This provides integrity of the sample. After the sample has been collected in the sampling tube (10), the release and retrieve assembly (14) is reinserted into the auger (28) and reattached to the sampling tube (10), which is then unlocked and retrieved out of the auger.</p> |
