Our article deals with the problem of unpleasant odors, which in recent years have become increasingly acute. In this paper describes Vilnius wastewater treatment facilities located near residential districts of Vilnius, such as Karoliniškės and Lazdynai. The article deals with odor dispersion and its dependence on distance to the source, wind direction, speed, etc. Studies were carried out in three stages: Exploring the Vilnius District wastewater treatment plant (Gariūnai, Maxima bazė, supermarket Karoliniškės, and Lazdynai) and investigating wastewater treatment plant access (up to 1,000 m from the treatment plant), and a third installment fully investigated odor dispersion in the Lazdynai District. Studies have shown that under certain weather conditions (favorable winds, high wind speed, high air temperature) odor dispersion, and intensification that has exceeded Hygiene Norm HN 121:2010, “odor threshold concentration of the living environment in the air,” to the specified maximum value.
