Abstract

Deep groundwaters from sites potentially suitable for the disposal of spent nuclear fuel have been chemically characterized. The waters are classified according to their contents of main constituents and pH as shallow or deep groundwaters. New equipment consisting of a mobile field laboratory and downhole pH and Eh probes has been successfully used in the investigations.

The deep groundwaters contain appreciable amounts of iron and sulphide and Eh values monitored downhole are more negative than those obtained from calculations based on the ferrous iron ferric hydroxide system. Laboratory simulations of the water rock interaction indicate that the dissolved oxygen is quickly removed when the water is in contact with the rock.
