ABSTRACT
The study presents waste disposal problems in inconsistent conditions and their effect onenvironmental factors. We analyzed in parallel the monitoring results for 6 months, 3 months, of soil qualityin the immediate vicinity of two landfills in different locations: Aiud (Alba County) and Gura Humorului(Suceava County). At building the deposits no sealing of the platform ground was done, and also thereweren’t provided any plans to make drainage systems, sewage collection and water infiltration through thelandfill. It is discharged into the soil, thus favoring the infiltration of various pollutants. This paper aims toassess the impact of inadequate storage conditions of domestic wastes. The objective is to determine theconcentration of soil heavy metals (Pb2+, Cu2+, Cd2+ and Zn2+) so as to evaluate the degree of soil pollutionin and around landfill sites in the two localities. After the test results came, we performed tables and graphsand drew conclusions from them, regarding the variation in pollutant, points most strongly influenced by thedeposit activity and correlation of monitored parameters.
