Prof. Ofer Dahan

Sensoil Ltd.

Ofer Dahan, is an associate professor at the Zuckerberg Institute for Water Research, Ben-Gurion University of the Negev, Israel. His main research activities relate to vadose zone hydrology, land use impact on groundwater quality, remediation of contaminated soils, and development of subsurface monitoring technology.
Throughout years of research he developed a Vadose zone Monitoring system (VMS) which is specifically designed for the study of water flow and contaminant transport in the unsaturated zone. The VMS has been successfully implemented in a wide range of scientific and commercial research projects including: (a) water flow and contaminant transport in the unsaturated zone; (b) long-term impact of agriculture on groundwater quality; (c) floodwater infiltration and groundwater recharge; and (d) bioremediation of contaminated sites.

Vadose Zone Monitoring Systems as a Key to Groundwater Protection

Minimization of subsurface pollution, as well as optimization of remediation strategies, is much dependent on the capability to obtain real-time information on the chemical and hydrological properties of the subsurface. Sensoil''s Vadose Zone Monitoring System (VMS) enables real-time measurement of water flow and contaminant transport across the unsaturated zone, from land surface to groundwater. This promotes effective protection of groundwater from pollution, and enhances remediation of contaminated sites.
