Abstract: 

The aim of this research is to investigate the existence and the three dimensional distribution of the pollution around Sarkhoun refinery. Following the initial investigation of the site, wells were dug up to hardpans followed by sampling. Soil pollution mappings and its distribution were performed by Surfer and Arc GIS and MATLAB softwares. The results showed that due to the lack of underground water in the area and the hardpans near soil surface, pollution spread has happened through gas spread from the limited region above the hardpan. Geostatistic studies and 3-dimential estimated pollutions mapping by software showed the range of studied polluted soil for TOG and TPH was 3633 and 2612 mg/Kg near burning pits and to 7 and 4 mg/Kg in the west south of the refinery. Furthermore, pollution spread in the direction of soil layers gradient is towards Salt River, which is placed in the east of the refinery. In the east of refinery, sudden increase in both pollution maps was related to the tube lines breakage. The result showed that TOG pollution map and TPH pollution map had similar trend. The results of the simulations revealed that in Sarkhoun soils by increasing in water debit to burning pits, risk of pollution spreading increased, Therefore appropriate remedy for blockage of spreading would be necessary.
