Groundwater flow in E and NE part of Bohemian Cretaceous Basin (3H, 14C, SF6 tracers, nitrate content) : mean residence time and question of effective contamination monitoring

Abstract

Study describes flow in aquifers in Bohemian Cretaceous basin using isotopic tracers. Flow system can be separated into 2 subsystems, each with very different mean residence time.
