ABSTRACT:
Liquid, such as ground water in a well casing, is sampled by lowering a submersible liquid sampling device to a submerged sampling position in the liquid, collecting a fixed volume sample of the liquid within a sample collection chamber in the submerged sampling device, and introducing a pressurized inert gas into the collection chamber to expel the fixed volume sample from the chamber through a sample transfer tube to a ground level sample receiver which may immediately analyze the sample or be removable for analysis of the sample in a separate laboratory.
