This study aims to establish a connection between the trihalogenomethanes content in drinking water of an infiltration intake and parameters characterizing water quality (turbidity, chromaticity, oxidizability), chlorine doses, and water consumption. Trihalomethanes include chloroform, bromodichloromethane, dibromochloromethane, and bromoform. It is known that trihalomethanes can harm public health. These compounds have a toxic polymorphism and can cause long-term effects, including carcinogenesis. It is shown that a satisfactory description of the trihalogenomethanes content can be obtained by modeling the annual cycle, taking into account the displacement of parameters (2-3 months), relative to the trihalogenomethanes content. Equations considering the displacement of water quality indicators have a high determination coefficient (0.95-0.97). The use of the same displacement for the time series of true values allows us to obtain equations with a sufficiently high determination coefficient, which indicates the possibility of their use for the predictive assessment of the trihalomethanes content in drinking water.
