Cooling towers, among other equipments, could have an important atmospheric impact, becoming a source of pollutants or biological agents. The most important, due to its frequency and importance of the outbreaks, is Legionella. Since its discovery in 1976 in Philadelphia, where the total number of cases reached more than 200 of those more than 30 died, several outbreaks have been reported causing tens of deaths. The most important one due to its spread took place in the city of Murcia (Spain), in 2001, with more than 600 cases and where 23 out of 70 investigated cooling towers were positive to Legionella Pneumophila. In the present work, a validated numerical modelization using the Computational Fluid Dynamics (CFD) code ANSYS Fluent is employed to simulate the dispersion of the drift from the cooling tower causative of the outbreak in the real urban environment of Murcia in the days of highest emissions, which are located by means of the number of infections given by the epidemic curve. ...
