Assessment of industrial pollution and water quality in the Nile River using GIS-based indices at Aswan, Egypt.

ABSTRACT: Industrial pollution represents a critical threat to freshwater ecosystems, particularly in regions where rivers serve multiple socio-economic functions. The Nile River in Aswan Governorate, southern Egypt, is a vital source of drinking water, irrigation, fisheries, and tourism, yet it is increasingly exposed to untreated industrial effluents. This study assessed the spatial extent and intensity of such pollution using geographic information system (GIS)-based spatial interpolation alongside two comprehensive indices: the weighted arithmetic water quality index (WAWQI) and the canadian water quality index (CWQI). Findings revealed distinct pollution hotspots near major industrial discharge areas, where water quality was classified as poor to very poor (WAWQI: 52.6-127.4; CWQI: 74.2-68.3).
