Contribution of Hydrogeophysical Data for the Assessment of Unconfined Aquifer Protection Levels - An Example from the Northeast of Brazil

Abstract: ABSTRACT. The use of chemical fertilizers in arable perimeters increases productivity, although it can degrade groundwater quality, particularly if such sources are unconfined. In this context, this paper presents the results of an analysis of the natural protection level of the Barreiras Aquifer in an area located on the eastern coast of northeastern Brazil. Such an aquifer presents an unconfined hydraulic character, making it susceptible to contamination from surface ground loads with contaminants associated… Show more
