Detergents in Drinking Water of Shiraz

The widespread use of detergents on the one hand and the lack of disposal on the other hand، increases the possibility of these materials to groundwater. In addition to causing toxicity in animals these materials also cause allergic diseases in people. The purpose of this study was to determine the amount of detergent in drinking water in the city of Shiraz. In this cross-sectional study، all drinking water sources in Shiraz (38 sources) was examined for two years: 1387 & 1390. Water sample data were recorded in a checklist and samples after ring transfer to laboratory were tested with Polarymetr Volta. All samples were with normal range of detergent. In this study، statistical test was performed and showed that the amount of detergents in alluvial wells were significantly more than calcareous and network drinking water. No correlation was foured between the amount of detergent and other physical and chemical factors. Although detergents and phosphate levels are rising but in none of the water resources of Shiraz، the amount of phosphate and detergent was higher than the standard range، but for high levels of nitrite and nitrate and the increasing process of the amount of phosphate and detergent in some wells، protecting wells and observing health and privacy sewage treatment is urgent.
