Evaluation and development of hydrogeological and geochemical investigation methods for aquifers of low permeability
The main aims of this study were to evaluate and test techniques for obtaining geohydrological data of the aquifers and aquitards of the Upper Creteceous and Lower Tertiary formations in the Netherlands. Current systems and methods for the determination of hydrogeological parameters of sediments around and above rock-salt formations are discussed. The results of the field study, set up to test the validity and applicability of test methods and measurement techniques for aquifers of low permeability, are presented. Details are given of the study on geohydrochemical methods which could provide useful information on the groundwater flow at large depths. This type of information might support formulation of hypotheses on deep groundwater flow and, at a later stage, on the validation of large scale groundwater flow models. Chemical and isotope analyses were performed on several borehole samples taken at different locations, both inside and outside the Zechstein Basin. The interpretation of stable and radioactive natural isotopes and of ionic ratios resulted in conclusions regarding the origin of the salinity of the groundwater samples. Conclusions and recommendations for future study are given as well as some guidelines for the establishment of new boreholes.
