The goal behind this work is defined as the study of the quality of water from karst springs near quarries exploiting limestone rock in order to assess its adequacy with domestic uses. At that end, a study at the mountain level was carried out. This mountain is in the Haouz area, in Tetouan, which is located north of Morocco and shelters active quarries. This research is based on the assessment of the physico-chemical parameters of the spring water used by local residents and located near this industry. The water quality evaluation was carried out by comparing the recorded values, according to Moroccan Standards related to the quality of water for human use. The review of some parameter’s indicative of water pollution (T °, pH, electrical conductivity, dissolved oxygen, turbidity, total dissolved solids and the alkalimetric total title) revealed that the quality of the studied spring water is good and does not present any health risk to the users of this water during the winter season.
Abstract. The Western Rif is a rural area characterized by rock extraction and agriculture. As a result, the surface of the land in the region is exposed to different sources of contamination which alters the quality of the soil. Leaching of the soil and runoff to surface water may impact the quality of surface water used by local people. A mapping of the land use by GIS of an area located at the level of the western Rif was carried out then an analysis of the interactions between the uses of the land; the practices, the quality of the surface layer of the soil and the quality of the water were made. Thanks to the processing of satellite images and to samples on the ground and assays of the physic-chemical parameters of soils and water (T °, pH, MES, turbidity, Nitrate, nitrite, phosphorus, nitrogen, etc.). The results of these analyzes revealed that these activities lead to an alteration in the quality of the surface layer of the soil, its characterization of which changes depending on the land use. Surface water is endowed with the components identified in the soil. This reveals that land use has generally negative physical and chemical impacts on surface waters.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
