Influence of the cemeteries in contamination of underground waters by phenolics compounds

Abstract

The phenol is one of the main compounds using in the prepare of bodies for burial. Objectified with this work evaluate the concentration of total phenols in groundwater that if are under direct influence of two urban cemeteries, both in a city in the Serrana region of Santa Catarina. Because don´t have studies that evaluate the contamination of the groundwater of cemeteries for total phenols, this study is a start point for deepened studies evaluate this contaminate and your dynamics in areas under influence of cemeteries. Was realized gathers of underground water in monitoring wells located inside of these cemeteries, in the four seasons, for one year. For the purposes of analysis, the pH and concentration of total phenols were determined by the colorimetric method. The results indicated high concentrations of total phenols, with minimum concentration of 0,03 mg L-1, in the autumn, and maximum of 2,72 mg L-1, in the summer. The concentrations observed in all the samples gathers, in all the seasons, was above of the value allowed for CONAMA regulation at the 396/2008, that is 0,003 mg L-1, charactering the environment contamination.
