Diagnóstico preliminar da explotação de água subterrânea na folha Quixeramobim (SB.24-V-D-lll), Ceará

Abstract

The present work features the preliminary results of the analysis of deep tube wells and of Quixeramobim's Map rainfall data (SB.24-V-D-III), provided by SIAGAS and FUNCEME,respectively. We performed a statisticai treatment of data from the wells 72 within the limits of Quixeramobim Map. The variabies were anaiyzed and integrated in order to search through their correlation statistics and contour maps, but there were few correlations. Through the correlation matrix there is a little significant correlation between the dynamic levei with the flow and depth of the wells and a slight relationship between the area of occurrence of higher rainfall and the contours of concentration area of higher values of fiows , which can be verified through contour maps. On the water quality, through the comparison with the reference values established in Decree 2,914/2011, it can be concluded that underground water have high salinity, thus making them unfit for human consumption.
