Appropriate monitoring techniques using bomb tritium and other geochemical parameters in hydrogeological investigations

Abstract: A critical review of earlier uses of bomb tritium spotlights problems in its applications that may result in erroneous interpretations. The old monitoring technique using boreholes causes mixing of groundwaters of different age zones. In this study, the mixing problem is overcome by using modern monitoring devices of multi-level samplers and bundle piezometers that yield groundwater samples of small volumes at closely-spaced intervals. The old method may be used to determine recharge and discharge areas of aqu… Show more

“…Tritium may represent inputs from both cosmogenic and fallout sources (Figure 1), but most hydrological significance attaches to the latter source and the fact that the tritium concentrations associated with precipitation falling since the thermonuclear testing of the 1950s will have been up to two orders of magnitude greater than the preexisting background levels (cf. Egboka, 1985). This has provided the basis for distinguishing recent and older groundwater and calculating their relative contributions to springs (e.g.…”
