Abstract
A sampling device includes a barrel having a downhole end, an exterior surface, an interior surface defining a hollow interior, and an open end at the downhole end of the hollow interior. A fluid entrance penetrates the exterior surface. A fluid path having an outlet port is fluidly coupled to the fluid entrance. The device is driven into a subsurface so that a soil sample is forced into the hollow interior. While the device is still in the subsurface a fluid sample is collected through the least one fluid entrance and fluid path.
