Sensoil Innovations provides a Vadose-zone Monitoring System (VMS) that enables continuous, real-time tracking of water movement and contaminant transport from the land surface through the unsaturated soil layer to groundwater. The system combines in-situ sensors and sampling units with a cloud-based platform, delivering data on hydrological and chemical subsurface conditions to support early detection and decision-making. VMS is used across sectors including groundwater protection, managed aquifer recharge (MAR), earthen dam and levee stability, land remediation, and smart mining. The system has been deployed globally in large-scale monitoring networks and supports environmental research initiatives such as the EU-funded SCENARIOS project on PFAS contamination.
