Here determination of the level dimensions regularity of the multicomponent contamination zones (by heavy metals and petroleum products) of the soils adjacent to the municipal solid waste landfill. The dependences of the mercury, copper and zinc concentrations in the soil on the distance to the landfill of municipal solid waste were determined, similar dependence was specified for petroleum products for a distance of up to 500 m. The research employed the regression analysis technique for investigating single-factor experiments and other paired patterns. The selection of a suitable function was based on commonly utilized options, determined by the criterion of achieving the maximum correlation coefficient value. Regression analyses were conducted by employing linearizing transformations, facilitating the conversion of non-linear regularities into linear forms. Graphical dependences, describing the change in the concentrations of individual soil pollutants with the distance from the municipal solid waste landfill have been built, they enable to demonstrating the satisfactory convergence of theoretical outcomes with empirical observations was achieved. The level regularity of multicomponent soil contamination (with petroleum products and heavy metals) at the distance from the municipal solid waste landfill has been obtained, it’s required for determining the dimentions of the zones of multicomponent soil contamination. Applying the method of iterations, the dimensions of the multicomponent contamination zones (with petroleum products and heavy metals) of the soils, adjacent to the landfill of municipal solid waste have been determined: very heavy pollution–22.93 m, heavy pollution–81.77 m, average pollution–474.9 m from the foot of the landfill.
