Abstract

Background: MTBE is an Oxygenated material additive to the petrol. This material is used in lead free petrol in order to help the fuel burn better and its formula is CH3(CH3)3. As the result, the elimination of Tetra Ethyl and lead Tetra methyl, used for better burning of fuel, would cause the reduction of air pollution and refinement of air from organic lead compounds. This material has high solubility in water and very low biological resolution property. As the result, the leakage of petrol containing above material through underground reservoirs in PETROL STATIONs can cause distribution of contamination in underground waters or would bring about the danger of contaminating drinkable water wells in cities.Materials and methods: In the first phase was designed is to determine the location of 107 fuel stations in the city of Tehran Out of this umber about 22 stations supplied liquid gas and therefore they were eliminated from the list. Then location of above stations transferred on to a 1/35000 map. By studying geological maps and topography of Tehran district and examining the movement trend of underground water from these maps we studied the movement trend of underground waters. In this phase, with regard to the information obtained from Water and Sewage Company of Tehran province, about 384 wells in an area of 2500 sq.m were located.Results: The overall places selected were 55 locations that from each location 4 samples were taken and then by mixing 4 samples one final sample was chosen for sending to the laboratory. This has been measured by CHROMATOGRAPHY GAS EQUIPMENT together with FID detector. Three locations of the overall sampling locations showed some measurable contamination but less than the standard level therefore in the final phase for each suspected location 5 independent water samples were obtained and once again they were measured. The results of the second phase test were negative.Conclusion: The results obtained show that after 2 years of using lead free petrol in the city of Tehran, at the present the underground resources of this city are free of any contamination with the above agent. But in some locations some contamination with the above mentioned agent has been shown, although very little, and this would increase the danger of contamination of underground waters with the MTBE.The final conclusion is that all locations in danger of contamination should be periodically tested by Water and Sewage Company of Tehran Province in order to protect the quality of drinking water in the city of Tehran and this is a vital factor.
