Wastewater from oil refinery in Khartoum produces high amounts of wastewater every daily and many recommendations were suggested e. g. to be used for irrigation of tree plantingln order to study the effect of the wastewater on the environment mainly the soil around the refmery, water samples were collected fi'om the treatment pond in the refinery and soil samples from dilferent sites were taken for quality assessment. The analysis of samples showed presence of high concentration of oil in the water and soil samples. Furthermore, a significant increase in concentration of some minerals was evident. Hence, it is recommended that application of refinery wastewater as irrigation water negatively affected soil quality and might cause soil pollution in the fixture.
