dc.description.abstract This paper analyzes the dispersion of soil pollutants from the sewage treatment mud from Tomesti, Iasi. The results were obtained by sampling soil samples from different depths (0-20 cm, 20-40 cm and 40-60 cm). The soil material, consisting of urban sludge, at all samples collected on the 0-20 cm depth shows well-developed structural aggregates, having a structure that varies from grain to sub-lime polyhedra with a medium development degree. The material exhibits hydrophysical properties - mechanical and hydric stability, consistency being moderately dry in a dry, moderately glue-like state, with macroporous, medium and large macroporous, resulting in good aeration porosity and optimum aerohydric regime. In the range of 20-40 cm the soil material is relatively well structured, with smaller structural aggregates, the lack of groundwater causing an increase in consistency, plasticity and reduction of interspaces between aggregates. For the depth between 40-60 cm the soil is well structured, with medium-sized aggregates with a grainy structure in the first part, subangular polyhedral in the sub-surface, micro and meso-good activity. The study area is the sludge dumps from Tomeşti from Iaşi. It was built in 1994 by removing the soil layer on an area of 9.1 hectares of land and the construction of surrounding and separating dams. Around the warehouse was made a drainage channel that ensures the drainage of the deposit. The warehouse is located in the major river bed of the Bahlui River, on its right side. The straight line to the Iaşi Wastewater Treatment Plant is about 2000 m. The sludge from the process of the Iasi wastewater treatment plant was transported to the warehouse through a pumping station and a discharge pipeline. en_US
