Notes
A thirty-year record of tritium in precipitation,
groundwater and surface water is used together with 85Kr and
other environmental tracers (CFCs, SF6) to evaluate the
dynamics of groundwater/surface water interaction and the
historical trends of nutrient loads and other contaminants in
groundwater and streams in the Odense Pilot River Basin.
Results demonstrate quantitative and qualitative effects of
both agricultural and urban practices on groundwater and
surface water systems including streams and coastal waters.
The radionuclides and the other environmental tracers, which
are used as tracers and groundwater dating tools, demonstrate
by themselves and when compared to hydrological model
simulations, that groundwater abstraction for e.g. the water
supply of the city of Odense affects the flow system and
deteriorate the groundwater quality e.g. where the water table
is lowered significantly. Groundwater dating by the
radionuclides and SF6 also demonstrate that CFC-12, which is
generally not considered to degrade in similar geochemical
environments, is degraded in the investigated anaerobic
aquifer leaving the CFCs unable to estimate absolute
groundwater ages at this site.
