The main objectives of the study to measure the concentrations of trihalomethanes (THMs) in drinking water of Cairo, Egypt, and their associated risks. Two hundred houses were visited and samples were collected from consumer taps water. Risks estimates based on exposures were projected by employing deterministic and probabilistic approaches. The THMs species (dibromochloromethane, bromoform, chloroform, and bromodichloromethane) ranged from not detected to 76.8 μg/lit. Non-carcinogenic risks induced by ingestion of THMs were exceed the tolerable level (10-6). Data obtained in this research demonstrate that exposure to drinking water contaminants and associated risks were higher than the acceptable level.
