In this study, the Total Organic Carbon, Nitrate and Petroleum hydrocarbons of Tehran's groundwater have been measured. According to this study, the average TOC was 9.3 mg/L, which is much above standard. For the Nitrate, although there were few samples below standard, samples above 45 mg/L were numerous, with a maximum of 133 mg/L. The Petroleum Hydrocarbon content of most of the wells was negligible, nevertheless there were two wells indicating MTBE content, which shows contamination from the underground tanks of nearby gas stations. In conclusion, Tehran groundwater needs special treatment to be used as a drinking water.
