Diagnóstico da qualidade da água subterrânea em poços nas áreas rurais de Caçapava do Sul -RS

Abstract

Water is a vital resource for life on earth and is of great importance for socioeconomic development. For this reason it is essential to look for ways to preserve the sources so that the water is free of contamination and suitable for human consumption. Thus, the objective of this work was to evaluate the physicochemical and microbiological quality of groundwater from four wells located in rural Caçapava do Sul -RS. For this, the water samples from the predetermined wells, named Point 1, Point 2, Point 3 and Point 4 were analyzed. The parameters evaluated were total alkalinity, chlorides, total coliforms, conductivity, total hardness, nitrate, pH, total solids and turbidity. The results obtained were compared with CONAMA Resolution 396/2008 and Ordinance 2.941 / 2011 of the Ministry of Health and demonstrated to be within the required standards, except for alkalinity and turbidity, which assumed high values for all points. Thus, with the results of this research, it was found the importance of analyzing the quality of groundwater resources to supply in areas with water limitations.
