Abstract
Olive oil production is one of the most important activities in the Mediterranean area and in Greece in particular. Olive oil production generates a large volume of liquid wastes which can cause severe pollution due to the high organic and in-inorganic load that they convey. In this work we assess the ability of time-lapse electrical resistivity tomography (ERT) technique to monitor Olive-oil mills’ wastes (OOMW) movement into an aquifer. Test involve performing extensive synthetic modelling using computer generated models for cross-hole ERT arrangements and applying various 4D time lapse inversion processing to the monitoring data. Further, 4D time lapse inversion was performed to cross-hole ERT data obtained during a tank experiment which involved simulation of OOMW movement into a saturated aquifer. Results validate the applicability of cross-hole time lapse ERT to monitor OOMW movement and help to decide ways for optimum data processing and collection.
