摘要

Precise delineation of contaminant plume distribution is essential for effective remediation of contaminated areas in and around unmonitored and not planned cemeteries. In these areas, the necrochorume is the primary source of contamination that reaches groundwater, putting the environment and the population residing around at risk. This contamination is bigger in sandy soils, as, in general, sandy soils are propitious to leachates migration in depth, promoting subsoil and groundwater contamination. Therefore, the present work identified contamination zones in an area occupied by a cemetery located in soils with high sand content, high permeability coefficient, and saturated hydraulic conductivity close to the city of Tramandaí, in the southernmost Brazilian state of Rio Grande do Sul. The results identified concentrations of organic matter and Biochemical Oxygen Demand above the maximum allowed values, clearly pointing to contamination of the samples collected. By using geophysical technique, the bidimensional profiles of apparent resistivity were obtained permitting the assessment and identification of the contaminant plumes. The results point to the necessity to improve burial practices below ground level, especially in areas where the natural characteristics favor the contamination of underground springs. In view of this, the importance of monitoring in these areas stands out as they can alter the quality of the environment and become a public health problem for the local and regional community.
