How to clean oil polluted ground water to make suitable for drinking and agriculture use?

Is it possible to remove the contaminated oil from ground water used for agriculture and drinking ? People living in Jaffna are facing a grave threat in accessing clean drinking water due to groundwater pollution caused by oil leakage. In recent days, oil waste is clearly observed in drinking-water sources (wells etc) in Chunnagam and Valigamam areas. Wells are the prime and mostly the sole source of water in Jaffna and this contamination is severely affecting the livelihood in those areas. This issue has resulted in scarcity for clean drinking water for the people living in the areas. No satisfactory action has been taken yet by authorities. Hence, there is an imminent need to create awareness of the issue to a wider audience in order to accelerate the phase at which actions are taken to solve the issue. Can any body give a sustainable solution fore this burning issue in Northern Sri Lanka?
