Remote sensing, GIS and chemical analysis for assessment of environmental impacts on rising of groundwater around Kima Company, Aswan, Egypt

Abstract

Abstract Background Kima company is located east of the river Nile, 2.5 km south of Aswan City. The Quaternary sands and gravels represent the main groundwater aquifer in the area. It is mainly recharged from the river Nile seepage between the high and the old Aswan Dams. Some water seepage comes from the fish hatchery canal close to the area. The objective is to study the temporal-spatial development of the drainage ponds resulting from the rise of the groundwater level in line with the agricultural and urban development in and around the Kima plant area using chemical analysis and advanced technology (remote sensing and GIS techniques). Results Many wells were drilled and used to pump the groundwater in and south of the area, from which 15 wells that were used to feed Aswan city by drinking water were stopped since 2009. As result, the groundwater level rises and most of the wells of Kima company flooded. The groundwater quality deteriorated and some environmental changes in the surrounding area were detected. Monitoring and analysis of these changes are studied using remote sensing and GIS techniques. The results show an increase in both the surface water bodies (ponds) and urban areas. Conclusions Since 2009, 15 productive drinking water wells were ceased in the study area. It is the main reason which caused more rising of the groundwater level accompanied by increasing of its salinity. The study detected and calculated the area influenced by the groundwater seepage, urbanization, and the agricultural reclamation areas. The successive changes in these parameters throughout the period 2007–2017 are calculated. Rising groundwater levels are expected to be a chronic problem and will likely be a major issue for residential areas of Aswan city.
