To ensure a reliable supply of clean drinking water under changing climatic conditions, land use, and increasing demand, artificial infiltration ponds are a key component of managed aquifer recharge systems. Optimizing their performance requires a detailed understanding of infiltration processes and subsurface transport dynamics. At a managed aquifer recharge (MAR) site in southern Sweden, a permanent Direct Current resistivity and Induced Polarization (DCIP) monitoring system has been installed for this purpose. It is complemented by sensors monitoring water conductivity, level, and temperature. To link field-scale observations with pore-scale processes, systematic laboratory spectral induced polarization (SIP) measurements are performed on in-situ sampled sediments from the infiltration pond. These controlled experiments provide complementary information on the hydraulic properties of the materials and support the interpretation of the field-based DCIP data.
