Abstract: Portable, self powered water pumping apparatus for use in sampling water in remotely located wells comprises a wheeled hose reel cart which supports a long length of plastic hose or tubing. The tubing has a small diameter length of inner tubing telescoped inside itself throughout most of its length. The inner tubing passes through the wall of the outer tubing near the upper end thereof and is connected to a pressurized cylinder of gas such as a standard 14 oz. propane gas cylinder. When the lower ends of the tubes are well submerged beneath the water level in a well, admission of gas to the inner tube at its upper end will force water up through an annular space between the tubes and out the upper end of the outer tube where it can be collected. A channeled plug at the bottom of the tubes prevents the tubes from collapsing, helps to keep them straight and together as they are lowered into the well and provides partial support for a weight hanging from the bottom of the tubes.
