Abstract: 

Shahid Hashemi Nejhad Refinery, which is one of the major gas refineries, is situated at a distance of 35 kilometers from Sarakhs and 165 kilometers from the city of Mashhad.

The Refinery has five gas treatment units, two Sulphur retrieval units, two fixation units for gas liquids, one acid water reduction unit, one wastewater refinery unit and various other subsidiary units.

Waste water refinery unit, has been set up to recycle sanitary wastewater of restaurant and convince services and part of industrial wastewater.

However, part of unrefined wastewater is released to refinery lands nearby.

Since the underground water resources in this region is high and in the other hand due to long detention time of waste water, it soaks in to underground water resources, and finally it causes an environmental catastrophy.

Regarding this issue we tried to make our research based on this problem.
In order to confirm the hypothesis of penetration of unrefined waste water into soil and underground water resources, in that region 5 wells were chosen and the parameters such as Cl-, SO4-2, NO2-, NO3-, COD, BOd, Color, pH, Cond., TDS, Ca+2, Mg+2, T. H., were done in June, July, October, November and December also analyzing of heavy metal and TPH were done on samples of the water wells in June, October and December. In order to have a crystal clear, comparisonal diagram which shows the fluctuation of measured parameters in five sample station were.
