The objective of this thesis was to evaluate the concentration of heavy metals due to the generation of leachates from the Haquira controlled landfill with respect to the Environmental Quality Standards (ECA) in the surrounding agricultural soils, applying a descriptive, quantitative methodology with a non-experimental research design. Simple and composite samples were taken from 10 sampling points, the concentration of heavy metals Arsenic (As), Barium (Ba), Cadmium (Cd), Chromium (Cr), Lead (Pb) and Mercury (Hg) were analyzed and physical-chemical parameters were analyzed; 1 sampling point of leachates where the concentration of heavy metals was analyzed, both analyses were carried out in dry and rainy seasons. The results of the research showed that the concentration of heavy metals in the agricultural soils was low. The physical and chemical composition of soils is related to the concentration of heavy metals, since these influence their dispersion and accumulation in soils. The concentration of heavy metals was compared with respect to the ECA's where concentrations of As were obtained from 2.58 - 6.78 mg/Kg; Ba from 101 - 353 mg/Kg; Cd from 0.02 - 0.327 mg/Kg; Hg from 0.03 mg/Kg; and Pb from 4.54 - 16. 9 mg/Kg for dry and rainy season, which do not exceed the ECA's for agricultural soils, with respect to total Cr, concentrations of 8.03 - 14.8 mg/Kg were obtained for dry and rainy season, which does not exceed the Canadian guide soil quality. The highest concentrations of As, Ba, Cd, Pb and Cr in the leachates were found during the dry season. Finally, the heavy metal dispersion model indicates that as the distance from the center of the landfill increases, the concentrations decrease.
