	This paper covers laboratory and modelling studies of antioxidant BHT (butylated hydroxytoluene) migration from HDPE pipe used in water supply systems. Our laboratory experiments were conducted on a measuring stand constructed on a new HDPE pipe. Determination of BHT concentration in pipe samples was performed with high-resolution size-exclusion chromatography (HR-SEC). Concentration of BHT migrating to drinking water in laboratory conditions was determined with a Trace-Ultra/Polaris Q (Thermo USA) GC-MS system. Modelling studies concerning BHT concentration in water body were performed using commercial CDF software Fluent, Ansys Inc. Our calculations were based on experimentally determined input data, such as diffusion coefficient, as well as initial and boundary conditions. The obtained modelling results showed good agreement with the experimental data.
