| Abstract | Introduction and Problem Statement The Mediterranean region accounts for no less than 97% of the world's olive oil production due to the favourable climatic conditions. Especially, Greece holds the third place worldwide in olive oil production and the island of Crete contributes approximately 5% to the total world olive oil production. The production procedure of olive oil generates large volumes of Olive Oil Mill Wastes (OOMW) with high organic load and rich in-inorganic constituents which lead to pollution of soil and water resources and therefore environmental degradation The OOMW are usually disposed in evaporation ponds which are rarely of proper size and wastewaters often overflow affecting neighbouring systems (soil, surface and groundwater) and other professional activities of the residents (agriculture, livestock farming). The base of the ponds is permeable and thus, the probability for groundwater and deep soil contamination is high. Consequently long-term disposal of waste, without necessary monitoring and protective measures may cause changes in the physico-chemical parameters of the surrounding ecosystems, with the risk of future non-tissue degradation of the environment. Moreover, older waste sites often lack reliable geological or artificial barriers and depositional information, to minimize the possibilities of further environmental damages. The problem of environmental degradation and waste management are of major concern of earth scientists and the local authorities. Geophysical methodologies in terms of Electrical Resistivity Tomography (ERT) can be used for monitoring the changes of the physical characteristics of the subsoil over time and identify the diffusion of the contaminants. An ERT monitoring experiment was conducted for the first time in an OOMW disposal site located in a test site in Crete. The purpose was to validate the resolvable capabilities of the method in capturing the spatial-temporal pollution caused by the low conductivity material of phenolic compounds. |
