Abstract
The use of 14C analysis for dating groundwater with ages up to about 40,000 BP was introduced by Münnich (1957, 1968). Eriksson (1958) proved that hydrodynamic mixing processes usually must be taken into account. But the piston flow model assuming simple convective flow is still used for the interpretation of 14C data (eg, Andres & Geyh 1970; Bath, Edmunds & Andrews 1979), despite its obvious oversimplification of the usual hydraulic situation.
