Resumo: | ABSTRACT Cemeteries are potential sources of groundwater contamination and, despite the several studies that evidence this sort of contamination, only a few consider how the aspects and characteristics of the unsaturated zone interfere in this process. This study evaluated the quality of groundwater in the areas of two cemeteries under the same precipitation regime, climate and burial practices, but with pedological differences. During one year, the physicochemical parameters potential hydrogen (pH), electrical conductivity, oxidation-reduction potential, dissolved oxygen, total dissolved solids, chemical oxygen demand, total phenols, total phosphorus and ammonia (NH3), as well as the heavy metals cadmium (Cd), lead (Pb), copper (Cu), chromium (Cr), nickel, (Ni) and zinc (Zn), were monitored in the groundwater from two cemeteries located in the urban area of the municipality of Lages, Brazil. Samplings were performed in monitoring wells inside the cemeteries and the local rainfall was registered. The quality of the groundwater from both cemeteries indicates contamination by necro-leachate constituents such as mineral salts, NH3, total phenols, Cd, Cr and Ni, which, besides being harmful to the environment, pose a risk to public health. The precipitation, which had a direct effect on the height of the water level in the groundwater aquifer, increased the levels of contaminants, while the reduced values of cation-exchange capacity (CEC), considering that a large part of the soil is occupied by Al3+ ions, reduced the adsorption potential of the other metals. |
