A Comparison of Two Multiple-Level Ground-Water Monitoring Systems

Source

In the context of the Canadian Nuclear Fuel Waste Management Program, Atomic Energy of Canada Ltd. (AECL) is conducting research into the underground disposal of nuclear fuel waste deep in stable plutonic rock. As part of this research, AECL has developed and tested many geotechnical instrumentation systems. Two multiple-level ground-water monitoring systems have been used to evaluate hydrogeological conditions in fractured rock and overburden materials: the Waterloo system and the Westbay system. Both instruments are designed to isolate several sections of a single borehole for ground-water measurements. The instruments were tested in adjacent boreholes drilled to about 60-m depth in granitic rock at the AECL's Atikokan research area in Ontario, Canada. Various aspects of these instrument systems, including the design, testing and sampling methods, and ground-water measurement data are compared. The information contained in this paper may assist future users to determine if these systems, or other systems, will be effective for their applications.
