Mean residence times of groundwater in shallow fissured rock aquifers; test site Lindau Germany

Mean residence times of groundwater in shallow fissured rock aquifers; test site Lindau Germany

Pages 175-181 1994

The evaluation of time series of natural isotopes ( (super 3) H- and (super 18) O-content of water samples) was carried out in order to gain informations about the mean residence time of groundwater at different depths at the Fissured Rock Test Site Lindau. A comprehensive sampling scheme was devised making use of a technical array of numerous wells and a 600 m long observation tunnel equipped with sampling galleries lying 90 m below the surface. The monitoring program included water samples from the unsaturated zone as well as from groundwater. The monitoring of seasonal isotope variations in water samples from the unsaturated zone was achieved with the help of ceramic suction cups and a small lysimeter. The groundwater samples were taken from springs, artesian and pumped wells exploring varying depths of the aquifer. The seasonal variations in the isotope contents of percolation water, groundwater and precipitation were evaluated considering lumped parameter models. The obtained results indicate a general groundwater age related stratification. This age related stratification seems to be characteristic for the aquifer under investigation and could be proved by vertical isotope profiles at several test wells. The profiles generally showed significant changes in the isotope content of water samples within a 10 m depth interval occurring approximately 25 m to 35 m below the surface. The measured (super 3) H- the (super 18) O-contents in water samples are directly correlated with the hydrochemical mineralization. The observed stratification of groundwater is interpreted to result from glacial processes and it seems to be characteristic for shallow groundwater in granitic plutons at the southern part of Germany.
