Abstract
Oil shale samples from Sultani oil shale mine, south of Jordan, were pyrolyzed by a partial combustion to generate shale oil. The produced water was sent for analysis. The different samples were analyzed for carbon content, and results showed that the TOC was 2010 mg per liter of retorted water. Phenol and arsenic contents were measured and found to be 64 mg and 0.18 mg per liter respectively. Phosphate and sulfate were also determined and found to be 35.7 and 5022 mg per liter. On the other hand, ammonium was also found to be 2831 mg per liter. Several elements were traced and reported in the present work, in which arsenic, chrome and nickel are the most important, and the retorted water was found to contain 0.18, 0.7 and 0.5 mg per liter.

The term TOC indicates total organic carbon presenting in retorted water
Summary
Water is necessary for producing shale oil. The amount and quality vary with technology. Water is produced during the processing (retorting) of oil shale that is not indigenous or tributary to local ground water or streams. Wastewater discharged from a retorting plant [3] contains oil, suspension solids, and oxygen nitrogen, and sulfur compounds. It can be treated by sedimentation, oil interception, flocculation, air flotation, and biological treatment. All liquid effluents from the oil shale thermal treatment plants consist of three wastewater streams [4]: Process water containing physically and chemically bound waters, industrial wastewater, and leachate containing different dissolved pollutants, such as phenols and mineral salts. We have tried to identify the different pollutant and contaminants of the retorted water
