Trihalo-methanes have been identified by the Cancer Research Institute as a carcinogen for humans. Considering that in Haft Rousta project, the source of drinking water supply is groundwater and water of Darood Zan dam and disinfection used is chlorine, this study was conducted to determine the concentration of trihalomethanes in drinking water of Haft Rousta project. The present study was conducted in the spring and summer of 2017. For this purpose, three villages (Abbasabad, Majd Abad, Kemar Zard) from Marvdasht city of Fars with a total of 9 stations were selected and the amounts of chlorine, pH, temperature, total organic carbon and trihalo methane were measured with three replications in water samples. The average concentration of trihalomethane compounds in this study was estimated to be 39 mg / l for Abbasabad village, 38.6 mg / l for Kemar Zard village and 39.7 mg / l for Majd Abad village. The highest recorded concentration was calculated in Majd Abad village with a concentration of 73 mg / l. The mean concentrations of chloroform, bromoform, bromodium chloromethane and dichloromethane and totality of halo methanes in network water in spring 1996 were 22.25 7 7.98, 11.42 90 3.90, 7.43 7 2.72, 51, respectively. 5.95 2 2.2, 47.06 15 15.70 mg / l in summer 96 are equal to 14.69 4 4.11, 7.55 99 1.99, 4.93 51 1.51, 1.49 3.95 ،, 31.13 97 7.97 mg / l were calculated. Due to the concentration of trihalomethane in the drinking water of the study area, the possibility of trihalomethane compounds due to the consumption of the studied waters is very low and the presence of this pollutant in this danger does not affect consumers in any age group.
