. An apparatus has been designed for collection of ground‐water samples in locations of limited water flow when atmospheric contamination must be avoided. The system consists of a packer outfitted with valves, a flow cell, and probes for measurement of dissolved oxygen, pH, and Eh, and is designed for installation in a 3‐inch (7.6‐cm) diameter borehole. The oxygen probe, which is a commercially available electrochemical device, functions accurately without water flow or oxygen consumption. The borehole collector system has been used to characterize the ground water in the Climax granite stock at the Nevada Test Site of the U.S. Department of Energy.
