A study of spatial heterogeneity of groundwater geochemistry is conducted within an abandoned underground quarry of chalk. An associated geophysical study (electromagnetic mapping at low induction number, and electrical resistivity tomography) is carried out on the surface. It allows to determine the structural geometry of superficial formations, in order to understand the link between the geochemical spatial variability of the lakes and the properties of the environmental medium.
