Abstract

In Morocco, irrigated perimeters are threatened by diffuse nitric pollution of groundwater, which reduces the potential of water resources which are of good quality, thus creating a health risk for the population and socioeconomic development in the country. Control of this pollution requires sufficient knowledge of the causes and mechanisms to address this problem. The Beni Mellal-Khénifra region suffers from the misuse of agrochemical inputs coupled with agricultural intensification and heavy pumping of groundwater, which is make water in the region of poor quality. Despite decades of efforts to reduce the release of pollutants into the environment, nutrient enrichment of aquatic environments remains an important issue, especially phosphates released into the environment, which come from agricultural sources (fertilizers), industrial wastes, human excrement and detergents as well as nitrates that turn into nitrites causing diseases that are sometimes fatal in newborns. In this context, this study considers the effects of the use of fertilizers on the water quality of the Tadla aquifer. It includes discussion based on various analyses of nitrates, nitrites, and phosphates from polluted areas and unpolluted areas.
