The necro chorume generated by the decomposition of human bodies has a high pollution load and depending on its location, it may reach and contaminate the soil, the surface and underground water resources. The problem is critical because the analyzed cemetery is located in a vulnerable area and the surrounding population makes use of the water under the influence of the necro chorume, and therefore, subjected to water carrying diseases. This study aimed to analyze the concentrations of heavy metals barium, copper, chromium and zinc in soil occupied by necropolis. An auger was used to collect soil samples in 10 different sites and depths. For determining the concentration of metals, the technique of fluorescence X-ray Energy Dispersive with the support of the software Surfer 10 was used to spatially generate concentration data maps. The concentrations of barium and copper indicated contamination of the soil in all sampled sites, while the chrome showed evidence of contamination at various depths between 0 and 300 cm. The lowest topographic point was the only one to have zinc concentration above reference values, indicating a contamination by this element in the surface flow and sub-surface water. With these results we can confirm the potential of metal contamination in soil occupied by the cemetery
